SUMMARY<br />

Today, ‘green buildings’ have become one of the most famous and<br />

fastest growing construction and design concepts; in fact, green<br />

buildings are doubling every three years worldwide. Owners, developers,<br />

architects, designers and even consumers are realizing its importance<br />

in sustainability, and expressing deep interest in the cost-efficiency,<br />

energy saving solutions, modern design, and the quality of life that such<br />

buildings are offering to present and future generations.<br />

Due to the built environment<br />

playing such a substantial role in the<br />

sustainable development discourse,<br />

Green Buildings hold particular<br />

importance, especially in cities; this<br />

is largely because buildings are the<br />

largest energy-consuming sector<br />

worldwide – accounting for more<br />

than 40% of global energy-use and<br />

responsible for an estimated 30% of<br />

city-wide emissions.<br />

In addition, buildings hold the most<br />

promise when it comes to “potential for<br />

global energy savings”; the International<br />

Energy Agency posits that the world’s<br />

built stock accounts for up to 41% of<br />

global energy savings potential by 2035.<br />

This is primarily due to green buildings<br />

using ~40% less energy and ~30%<br />

less water than in standard buildings<br />

of the same size. Furthermore, there<br />

are roughly 8-<strong>10</strong> million new buildings<br />

constructed each year, worldwide.<br />

Imagine a world where each of those<br />

new buildings erected each passing<br />

year were resource- and cost-efficient,<br />

consuming less energy and water,<br />

releasing less CO 2<br />

emissions, improving<br />

air quality, and built to be more durable<br />

than our standard building stock; the<br />

world would undoubtedly be making<br />

a gigantic step towards sustainable<br />

development and the greater good.<br />

Although the area of sustainable and<br />

green development has received<br />

a lot of attention from researchers<br />

and practitioners, with many papers<br />

being published on “Green Cities” or<br />

“Sustainable Cities”, very few public<br />

papers have tried to collate and<br />

evaluate data on the progress made in<br />

the development of green buildings in<br />

Global Cities. In particular, few report<br />

on the rate of green building adoption,<br />

or the efficiency and performance of<br />

the built environment within these<br />

cities. This paper seeks to compare<br />

the performance of <strong>10</strong> Global Cities<br />

specifically with regards to Green<br />

Buildings.<br />

In order to rank these cities’ green<br />

building performance, a set of criteria<br />

has been developed. The methodology<br />

developed assesses the Global Cities<br />

for their green building performance<br />

across four categories, out of which<br />

three focused on total number of green<br />

2<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings


uildings, performance and initiatives,<br />

and one category focused on the city’s<br />

green initiatives, which provides a<br />

supportive infrastructure that fosters a<br />

healthy green building movement.<br />

After assessing the <strong>10</strong> Global Cities<br />

for green building performance, the<br />

leading cities were found to be Paris,<br />

followed by Singapore and London.<br />

Sydney, Tokyo and Hong Kong came<br />

respectively in the fourth, fifth and<br />

sixth positions. While New York, Dubai,<br />

Beijing, and Shanghai were the laggards<br />

on this ranking.<br />

When evaluating the Global Cities<br />

on the number of green buildings<br />

and the certification systems in use<br />

(for green buildings), the research<br />

identified Singapore, London and Paris<br />

as the top scorers. These three top<br />

cities are advanced in the adoption<br />

of new and existing green buildings,<br />

and experience a high level of green<br />

building activity.<br />

It should be noted that though Beijing,<br />

Dubai and Shanghai lagged in many<br />

green building indicators compared to<br />

its other Global City peers, these cities<br />

are among the most recent joiners of<br />

the green building movement; when<br />

considering the limited number of<br />

years that Beijing, Dubai and Shanghai<br />

have been working to green their<br />

built stock, the achievements of these<br />

cities are profound, especially when<br />

considering the large number of highly<br />

internationally-certified buildings<br />

currently standing within these cities.<br />

When the Global Cities were ranked<br />

based on the overall performance<br />

and efficiency of the built stock, the<br />

research concluded that Paris and<br />

Singapore are amongst the best<br />

performers; this confirms that the<br />

green building efforts in Singapore and<br />

Paris are palpable, and that the local<br />

green building standards are stringent<br />

enough to produce tangible results.<br />

Although attempting to compare and<br />

rank the numerous green building<br />

policies and codes would pose a<br />

challenge due to their volume and<br />

diversity, Singapore did indeed stand<br />

out as a pioneer in the industry by<br />

putting a comprehensive and bold set<br />

of policies and targets for greening<br />

the city’s built block. As a city that has<br />

committed to greening 80% of its builtstock<br />

by 2030, Singapore stands out as<br />

one of the most ambitious cities on the<br />

list of cities evaluated.<br />

Finally, the assessment of the citylevel<br />

green initiatives established that<br />

both Sydney and Hong Kong have set<br />

higher than average CO 2<br />

reduction<br />

targets amongst the <strong>10</strong> Global Cities,<br />

and have also proven themselves<br />

as they perform noticeably well with<br />

low CO 2<br />

emissions city-wide and high<br />

percentages of waste recycling. Paris,<br />

Singapore, and New York also seem to<br />

perform extremely well on the green<br />

initiatives by implementing appropriate<br />

green solutions for waste and energy<br />

efficiencies.<br />

Thus, for all the above mentioned<br />

reasons, it is important to benchmark<br />

and publish the green building<br />

performance of the largest, most<br />

attractive Global Cities, in order to<br />

evaluate global progress towards<br />

sustainable development, increase<br />

knowledge-sharing, share bestpractices,<br />

and better understand what<br />

is and is not working.<br />

METHODOLOGY AND<br />

MEASUREMENTS<br />

Selecting the Global<br />

Cities in the Ranking<br />

The Global Cities selected for this<br />

white paper were adopted from The<br />

Globalization and World Cities Research<br />

Network (GaWC) approach, which is<br />

a leading academic think-tank that<br />

classifies and researches Global Cities.<br />

As per GaWC, Global Cities are heavily<br />

ranked based on economic factors,<br />

followed by political and cultural<br />

factors. Cities are sorted into three<br />

major categories: Alpha, Beta, and<br />

Gamma. The top <strong>10</strong> Global Cities are<br />

comprised of the Alpha++ and Alpha+<br />

cities, which are vastly more integrated<br />

with the global economy than others.<br />

Due to the similar levels of integration,<br />

pressures, and dynamics of these top<br />

<strong>10</strong> GaWC Global Cities, these were<br />

the Global Cities (outlined in Table 1)<br />

selected to become the basis of this<br />

white paper.<br />

Ranking Cities by Green Building Performance<br />

This paper seeks to compare the performance of these <strong>10</strong> Global Cities specifically with regards to Green Buildings. Each of<br />

these cities were analyzed to assess each city’s green-building policies and targets, adoption of green building certification and<br />

construction projects, and the efficient performance of the city’s built-environment.<br />

In order to rank these cities’ green building performance, a set of criteria was developed. The methodology developed<br />

assesses the Global Cities for their green building performance across four categories, out of which three focus on the<br />

total number of green buildings, performance and initiatives, and one category focuses on the city’s green initiatives and<br />

performance. The data used across all metrics was collected up to the end of year of 2014.<br />

Green Building Metrics<br />

1. City-wide Green Building Landscape<br />

This category assesses the total number of green buildings in each city, and<br />

assesses the <strong>10</strong> Global Cities on the number of green buildings, the certifications<br />

given to those buildings, and the availability of green building credentialed<br />

professionals in the city.<br />

The metrics in this category are as follows:<br />

• The % of green buildings versus total number of buildings<br />

• Number of green buildings<br />

• Number of green building credentialed professionals per building<br />

The abovementioned metrics are assessed and analyzed thoroughly in Chapter 4.<br />

2. Green Building Efficiency and<br />

Performance<br />

This category evaluates the current efficiency and<br />

performance of buildings within each of the <strong>10</strong> Global<br />

Cities by measuring CO 2<br />

emissions and energy use<br />

of each city’s built environment. Water consumption<br />

was also evaluated, but not enough reliable data was<br />

available for inclusion.<br />

The metrics in this category are as follows:<br />

• CO 2<br />

emissions from buildings<br />

• CO 2<br />

emissions from buildings per capita<br />

• CO 2<br />

emissions from buildings per GDP<br />

• Energy consumption from buildings<br />

• Energy consumption from buildings per capita<br />

• Energy consumption from buildings per GDP<br />

The abovementioned metrics are assessed and<br />

analyzed thoroughly in Chapter 5.<br />

3. Green Building Policies and Targets<br />

This category identifies available city green building codes and targets, and compares them amongst the <strong>10</strong> Global Cities.<br />

The metrics in this category are as follows:<br />

• Green building code<br />

• City-wide green building targets<br />

The existence of the abovementioned metrics is assessed and discussed in Chapter 6. It should be noted that only the<br />

development and existence of green building codes and targets were assessed for the purpose of this paper; the effectiveness<br />

or resulting impact of these codes and targets being put in place was not compared, as the analysis required is too subjective.<br />

Thus, this chapter discusses the differences between city-wide codes and green building targets, solely for the purpose of<br />

knowledge-sharing.<br />

Green City Metrics<br />

1. Green City Culture and Environment<br />

This category looks at the city-level green initiatives in<br />

each city and evaluates the effectiveness of the adoption<br />

of those initiatives. Because the green building movement<br />

thrives in sustainability-oriented cities which have policies<br />

and leadership that provides an enabling and fostering<br />

environment, it was important to have one set of metrics that<br />

measured the sustainability culture of a city.<br />

The metrics in this category are as follows:<br />

• Climate action plan<br />

• City-wide CO 2<br />

emissions<br />

• City-wide CO 2<br />

emissions per capita<br />

• City-wide CO 2<br />

emissions per GDP<br />

• % of CO 2<br />

emission reduction targets<br />

• % of renewable energy consumed by the city<br />

• % of waste recycled by the city<br />

The abovementioned metrics are assessed and analyzed<br />

thoroughly in Chapter 7.<br />

CHAPTER 2<br />

INTRODUCTION TO<br />

GREEN BUILDINGS<br />

The Green Building Movement<br />

In 1987, the Brundtland<br />

Commission (formerly known<br />

as the World Commission<br />

on the Environment and<br />

Development (WCED) issued the<br />

Brundtland Report at the United<br />

Nations, which first defined<br />

sustainable development as the<br />

“development which meets the<br />

needs of the present without<br />

compromising the ability of future<br />

generations to meet their own<br />

needs.” Therefore, the pursuit<br />

of sustainability requires holistic<br />

thinking in order to understand<br />

how and to what degree each<br />

developmental element affects its<br />

surroundings. By understanding<br />

and measuring these impacts, we<br />

can seek to minimize each effect.<br />

Today, ‘Green Buildings’ have<br />

increasingly become one of<br />

the most growing construction<br />

and design concepts. Owners,<br />

developers, architects, designers<br />

and even consumers are realizing<br />

its importance in sustainability.<br />

When the resource-efficiency<br />

of these green buildings are<br />

coupled with modern designs<br />

and an enhanced quality of life<br />

– the “Business Case for Green<br />

Buildings” quickly become an<br />

attractive one, to both present<br />

and future generations.<br />

The aim of this white paper is to<br />

evaluate Global Cities particularly<br />

on green building performance.<br />

This is particularly important<br />

because green buildings are<br />

one of the most important<br />

elements to the sustainable<br />

development discourse, and the<br />

built environment plays a very<br />

substantial role in cities. In fact,<br />

buildings are the largest energyconsuming<br />

sector worldwide<br />

– accounting for more than 40%<br />

of energy use and responsible<br />

for an estimated 30% of city-wide<br />

emissions.<br />

The focus of this chapter will be<br />

to introduce the concept of green<br />

buildings, highlight the benefits<br />

of building green, and identify<br />

prevailing trends in the green<br />

building movement.<br />

What are Green Buildings?<br />

Green Buildings present itself as an opportunity to generate<br />

tangible results towards sustainable development. The<br />

practice of green buildings drives environmental, economic<br />

and social benefits; this is done by fostering the efficient<br />

operations of buildings through the responsible use of<br />

resources in construction and operations, enhancing<br />

durability, and therefore lowering both operational and longterm<br />

maintenance costs, and often driving up the quality of<br />

life in these built environments.<br />

Green buildings are known to have less negative impacts<br />

on the environment in comparison to standard buildings<br />

of the same size. They are designed, developed, and run by<br />

taking into consideration key elements such as indoor air<br />

quality, efficient resource use (e.g. use of energy, water, and<br />

materials), outdoor views, and synergy with the surrounding<br />

landscape.<br />

Benefits of Building Green<br />

Green buildings play a major role in…<br />

• Decreasing energy use. With the integration of<br />

renewable and zero carbon technologies, green<br />

buildings are made more comfortable, less costly to<br />

operate, and increasingly energy efficient. In essence,<br />

42% less energy is used in a green building than in a<br />

standard building of the same size.<br />

• Reducing water waste. Innovative ways are adopted<br />

in order to achieve water conservation. In fact, statistics<br />

show that 34% less water is wasted in a green building<br />

than in a standard building of the same size.<br />

• Minimizing waste and encouraging reuse. Waste<br />

generation can be minimized through the use of durable<br />

materials and the design of recycling systems. This will<br />

lower waste costs since recycling generally costs less<br />

than getting rid of landfill.<br />

• Conserving natural resources. By maximizing the<br />

use of re-usable, renewable, sustainably managed<br />

materials, it is ensured that buildings make truly low<br />

impacts.<br />

• Boosting employee productivity. Employee<br />

productivity in a green commercial building can be<br />

boosted by 15%, which can strongly affect the attraction<br />

and retention of human capital.<br />

• Supporting a healthier lifestyle and enhancing<br />

well-being. Commercial and residential green<br />

buildings produce efficient heating, ventilating, and<br />

air-conditioning systems to provide high quality indoor<br />

air, and incorporate natural light and views. This creates<br />

an excellent environment for the people residing in or<br />

occupying those buildings, which in turn enhances their<br />

comfort and satisfaction.<br />

“People spend more than 90 percent of<br />

their time indoors — from homes to offices,<br />

schools, retail stores, fitness centers,<br />

health care facilities, and more — which<br />

means that buildings, and everything<br />

in them, can have a profound effect on<br />

human health and well-being. Our built<br />

environment can shape our habits and<br />

choices, regulate our sleep-wake cycle,<br />

drive us toward healthy and unhealthy<br />

choices, and passively influence our health<br />

through the quality of our surroundings.<br />

The WELL Building Standard (WELL)<br />

is the first building standard to focus on<br />

health, and health provides a framework<br />

to incorporate a variety of strategies to<br />

integrate human health and well-being at<br />

the heart of building design, construction<br />

and operations. The standard also has the<br />

potential to transform the way humans<br />

interact with the buildings and spaces they<br />

live in through innovative design.”<br />

– Paul Sciallia, Founder of WELL Institute, U.S.<br />

Central Park Sydney, Australia<br />

When considering just some of the benefits of ‘building<br />

green’, it is easy to see why this is a strategic initiative worth<br />

pursuing for many cities and countries at a government level.<br />

Green cities are also linked to better well-being and greater<br />

popularity, which can enhance a city’s competitiveness,<br />

leading to enhanced tourism and other economic revenues<br />

for a city. As more and more cities are trying to mitigate<br />

their negative footprint on the environment and reduce the<br />

operational costs of running their own cities, a “green-built<br />

environment” becomes increasingly important.<br />

Prevailing Trends in<br />

Green Buildings<br />

The global supply and demand for<br />

green building is on the rise as owners,<br />

engineers, contractors, and tenants<br />

realize the importance of the long-term<br />

market opportunity.<br />

1. There is a major shift in the<br />

expectations stakeholders have<br />

of their own buildings. The level<br />

of education in relation to green<br />

buildings and green materials<br />

from key stakeholders such<br />

as architects, developers, and<br />

end-users is growing. The global<br />

green building materials market is<br />

anticipated to grow at a Compound<br />

Annual Growth Rate (CAGR) of<br />

around 13% during the 2015-2020<br />

period. As already explained,<br />

green buildings are service<br />

providers of enhanced health and<br />

well-being, better environment,<br />

and minimized operating costs.<br />

Consequently, the green building<br />

material market is also expected to<br />

reach USD 234.77 billion by 2019.<br />

2. An increasingly cost-conscious and<br />

financially conservative world has<br />

emerged in the aftermath of the<br />

global financial crisis, coupled with<br />

the recent volatility in the price of<br />

fossil-fuel based energy. In such a<br />

global context, the long-term costsavings<br />

of a green building that<br />

consumes less energy and utilizes<br />

renewable energy is growing<br />

in demand. Accordingly, the<br />

International Energy Agency (IEA)<br />

posits that renewable energy will<br />

represent the largest single source<br />

of electricity growth over the next<br />

five years, and is expected to top<br />

700 gigawatts by 2020 – which is<br />

more than twice Japan’s currently<br />

installed power capacity.<br />

3. Globalization is boosting<br />

sustainable real estate<br />

development worldwide and<br />

aligning regulations. The flow of<br />

economic and intellectual capital<br />

in international trade is helping<br />

to emphasize the adoption of<br />

energy-efficient building practices<br />

and world-class designs; this<br />

has contributed significantly in<br />

achieving public awareness on<br />

environmental concerns and<br />

the need for adopting greener<br />

solutions.<br />

With the increasing demand for green<br />

buildings, developers and clients are<br />

realizing the business, social and<br />

environmental value that green projects<br />

are providing. Global green building<br />

activity is steadily on the rise. In 2009,<br />

only 13% of developers responding to<br />

a survey stated that over 60% of their<br />

firms’ construction projects were a<br />

‘green building’. In 2015, green activity<br />

was four times higher, where over 50%<br />

of all respondents stated that more<br />

than 60% of their firms’ construction<br />

“Singapore can certainly be considered a leader in<br />

the field of green building. The city target for 80<br />

per cent of buildings to achieve BCA Green Mark<br />

standards by 2030 is ambitious but achievable, and<br />

the Singapore Green Building Council (SGBC) will<br />

play a key role in delivering this!”<br />

“Singapore and London are the cities which have the<br />

highest green building activity, and Costa Rica, France,<br />

Singapore, and the United Kingdom are the countries that<br />

witness high demand for green building materials”<br />

– Michael Scarpf, Head of Sustainable Construction at Lafarge Holcim, Switzerland<br />

After assessing the ten Global Cities<br />

for green building performance, the<br />

winning city is Paris, followed closely by<br />

Singapore. London rounds out the <strong>Top</strong><br />

3 performing cities.<br />

Paris and Singapore took the top spot<br />

by excelling in all four assessment<br />

categories: City-wide green building<br />

landscape, green building efficiency and<br />

performance, green building policies<br />

and targets, and green city culture and<br />

environment. They were the only cities<br />

that ranked within the <strong>Top</strong> 5 in every<br />

category.<br />

Both Paris and Singapore have strong<br />

building efficiency and performance,<br />

which shows that both local and international<br />

certification standards are<br />

yielding high-performance on green<br />

buildings. London benefits from high<br />

yield of green buildings in the city,<br />

which can be linked to the fact that the<br />

United Kingdom was the first country<br />

ever to introduce a green building<br />

certification system (e.g. BREEAM). Paris<br />

16<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings<br />

fell just slightly short of Singapore in<br />

the absolute number of green buildings<br />

in the city, and by not setting out a clear<br />

city-wide green building target.<br />

Sydney, Tokyo, and Hong Kong came<br />

respectively in the fourth, fifth and sixth<br />

positions. Although the three cities<br />

performed extremely well on the green<br />

city culture and environment, Sydney<br />

and Hong Kong’s ranks were negatively<br />

affected with the poor results<br />

they achieved on their green building<br />

landscape and performance. Quite<br />

surprisingly, Sydney had the fewest<br />

absolute number of green buildings in<br />

the city, with only 67 green buildings<br />

to date. New York followed as number<br />

7. It has a relatively healthy number<br />

of green buildings constructed within<br />

the city, with 287 (5th) and 320 (4th)<br />

green buildings respectively, due to<br />

having the largest built-environments<br />

in comparison to the other cities, the<br />

percentage of green buildings as per<br />

the total built landscape ranked these<br />

cities as laggards.<br />

Finally, Dubai, Beijing, and Shanghai<br />

were the last cities on the list; this was<br />

an unsurprising result, as these three<br />

cities are amongst the most recent to<br />

join the green building movement. It is<br />

expected that these rankings should<br />

see changes in the future as these<br />

newer ‘green building cities’ are setting<br />

ambitious targets in order to catch up<br />

to other cities’ levels.<br />

Dubai, for example, launched its local<br />

green building standard last among<br />

these <strong>10</strong> Global Cities, in 20<strong>10</strong>, resulting<br />

in fewer locally certified buildings<br />

(8th), and only launched its green<br />

building regulations and specifications<br />

in 2012. Despite the slow start, Dubai<br />

ranks 5th in internationally certified<br />

green buildings (<strong>10</strong>4), and has a total of<br />

147 internationally and locally certified<br />

green buildings erected on its<br />

cityscape. Dubai already ranks 6th for<br />

‘green buildings as a percentage of<br />

total buildings’ and is certainly a city to<br />

watch, as the city seems to work quickly<br />

to recover lost time.


“The UAE is running<br />

behind, compared to its<br />

European counterparts,<br />

but it won’t be like that for<br />

long. We are learning from<br />

others’ experience,<br />

mistakes and best<br />

practices, and adapting<br />

‘old concepts’ to our own<br />

environment and situation.<br />

This is placing the emirate<br />

at a privileged position<br />

where we can focus on the<br />

right aspects from the very<br />

beginning and become a<br />

playground for innovation<br />

and an example for the<br />

other countries in the<br />

region.”<br />

CHAPTER 4<br />

GREEN BUILDING<br />

LANDSCAPE<br />

How Green is the Built<br />

Stock of Global Cities?<br />

Green Buildings<br />

are doubling every<br />

3 years worldwide.<br />

*The absolute number of green buildings: The total<br />

number of green building projects or certification<br />

applications submitted for each city.<br />

Green Buildings are rapidly increasing<br />

– doubling every three years worldwide<br />

as a response to accelerating demand<br />

for sustainability. Green Buildings have<br />

proven to not only minimize the impact<br />

of humankind on the environment but<br />

also to improve social and economic<br />

conditions.<br />

That being the case, cities worldwide<br />

are taking the action to “green” their<br />

built stock and integrate sustainability<br />

principles into the design and planning<br />

process of construction.<br />

Therefore, Global Cities were assessed<br />

on the basis of their green building<br />

landscape, which is defined as the total<br />

number of green buildings and green<br />

building certification systems in use.<br />

The Green Building landscape is an<br />

important dimension to consider since<br />

it shows the overall current uptake of<br />

Green Buildings across our <strong>10</strong> Global<br />

Cities.<br />

London, Singapore and Paris take the<br />

top 3 spots with regards to Green<br />

Building Landscape. This is primarily<br />

due to these three cities scoring in<br />

the top 3 for both *the absolute<br />

number of green buildings and on<br />

the ‘green buildings as a percentage<br />

of total number of buildings’ metrics.<br />

London and Paris particularly scored<br />

high with 68% and 64% of the built<br />

environment comprising green<br />

buildings, respectively; Singapore<br />

followed with 48% of its built landscape<br />

being “green”. Singapore and London,<br />

in particular, also had a very high rate<br />

of absolute number of green buildings<br />

with 2,339 and 1,729, respectively.<br />

Paris also ranked 3rd in absolute<br />

number of green buildings, but scored<br />

relatively low in comparison to the top<br />

2 cities with just 456 green buildings<br />

This chapter gives a brief overview<br />

of sustainability ratings for building<br />

and construction projects, and the<br />

associated certifications systems; and<br />

evaluates cities based on the total<br />

number of green buildings, comparison<br />

of the number of locally and<br />

internationally certified buildings, and<br />

certified credentialed professionals.<br />

Green Building<br />

Certifications<br />

Green Building Certification is an<br />

integral part of the planning and<br />

construction of sustainable buildings.<br />

From the early 1990s, the number<br />

of sustainability tools along with the<br />

number of buildings certified have<br />

increased dramatically worldwide. In<br />

addition to standards for design and<br />

construction of buildings in line with<br />

sustainability goals set by government<br />

authorities, there now exist more than<br />

600 green building certification systems<br />

globally.<br />

These green building ratings or<br />

certification systems are measuring<br />

tools that provide guidelines for the<br />

planning and construction of buildings<br />

while taking into consideration<br />

environmental, economic and social<br />

factors. Moreover, they allow building<br />

owners and developers to confidently<br />

label their buildings as “green” in<br />

a standardized and recognizable<br />

format. The assessment instruments<br />

measure, rate and certify the level<br />

of compliance and performance of<br />

a building with alignment to specific<br />

environmental goals and requirements<br />

set by the standardization organization,<br />

often in line with city-targets, thereby<br />

contributing to the achievement of<br />

those targets.<br />

The first Green Building rating system<br />

in the world was created in the UK in<br />

1990 and named the Building Research<br />

Establishment’s Environmental<br />

Assessment Method (BREEAM). It is<br />

a multi-attribute rating system that<br />

integrates the assessment of the<br />

following key categories: Water, Energy,<br />

Material, Innovation, Management,<br />

Land Use & Ecology, Health & Well-<br />

Being, Pollution, and Waste. Being<br />

highly recognized globally, it has served<br />

as a basis for numerous countryspecific<br />

schemes for rating systems,<br />

such as Hong Kong’s 4-star Green<br />

Building Certification System.<br />

Despite BREEAM being the first green<br />

building rating system, the most widelyused<br />

Green Building rating system<br />

around the globe is the Leadership<br />

in Energy and Environmental Design<br />

(LEED) system, launched in the United<br />

States. It was established by the U.S.<br />

Green Building Council in 2000 for<br />

the sustainability assessment and<br />

rating of green building projects.<br />

LEED assesses projects on the basis<br />

of credits earned across the following<br />

seven categories: Site Selection, Water<br />

Efficiency, Energy and Atmosphere,<br />

Materials and Resources, Indoor<br />

Environmental Quality, Regional Priority,<br />

and Innovation in Design. Credits are<br />

evaluated and eventually result in a<br />

point score compatible with four levels<br />

of LEED certification: Certified, Silver,<br />

Gold, and Platinum.<br />

In order to stimulate the demand for<br />

sustainable buildings and to suit the<br />

individual climatic, cultural and legal<br />

boundary conditions, many countries<br />

have designed and began adopting<br />

their own Green Building rating<br />

systems (Figure 5). In fact, all <strong>10</strong> cities<br />

in our Global Green Building Cities<br />

Ranking have developed their own local<br />

certification. Although each certification<br />

differs in the ratings awarded and<br />

categories assessed, the Green Building<br />

evaluation principle of “awarding credits<br />

for each pillar” is the same.<br />

Today, there exists<br />

more than 600<br />

green building<br />

certification<br />

systems globally.<br />

“Part of the difficulty with both LEED and<br />

BREEAM systems is the one approach across<br />

multiple geographies, climates and cultures. For<br />

example, transportation needs in Texas are very<br />

different from Singapore; water security in Beijing<br />

is different to Manila which requires different<br />

issues to be ranked differently to match local/<br />

regional environment and regulations.”<br />

“All three cities – London, Paris, Singapore – are clearly<br />

advanced in the field of green buildings in terms of<br />

standards and actual certified buildings and landmarks.<br />

They also have a long history of urban planning, research,<br />

regulations and frameworks, which make them examples<br />

– Saeed Al Abbar, Chairman of Emirates Green Building Council, United Arab Emirates<br />

WHO’S PERFORMING BETTER IN <strong>THE</strong> TOTAL NUMBER OF GREEN BUILDINGS?<br />

By ranking the Global Cities by total<br />

number of green buildings, Solidiance<br />

has estimated the number of Green<br />

Buildings as a percentage of total<br />

number of buildings in each city (Figure<br />

6). It should be noted that ‘the total<br />

number of buildings’ was derived<br />

from adding up the total number of<br />

skyscrapers and the total number of<br />

high-rise buildings in a city. Due to the<br />

inconsistency of available data, and<br />

green building certifications generally<br />

targeting high-rise buildings firstand-foremost,<br />

low-rise buildings and<br />

other types of buildings (ie. churches,<br />

etc.) were removed from the total<br />

building count for the purposes of this<br />

paper. The total number of Green<br />

Buildings for each city is a sum of<br />

building projects certified by LEED,<br />

BREEAM and local certification<br />

systems.<br />

With regards to the city leading the<br />

Green Buildings chart, London has the<br />

highest percentage of green building<br />

projects (68%) for its total number of<br />

green buildings among the ten Global<br />

Cities chosen. Abreast of London,<br />

Paris also has more than half of the<br />

built stock (64%) certified as ‘Green’.<br />

Singapore, with the concerted efforts<br />

of its government agencies, round<br />

out the top three Global Cities with<br />

48% percent of total number of green<br />

buildings. It is worth noting here that<br />

the fact that the total number of<br />

buildings was limited to two types<br />

of buildings (High-rise buildings 1<br />

and Skyscrapers 2 ), had an impact on<br />

generating such high percentages.<br />

1<br />

High-rise buildings are defined as a multi-story structure between 35-<strong>10</strong>0 meters tall, or a building of unknown height from 12-39 floors.<br />

(source: http://www.emporis.com/building/standard/3/high-rise-building)<br />

While looking at the number of total<br />

buildings, the inconsistency between<br />

the percentage of Green Buildings and<br />

number of total buildings is noticed.<br />

For instance, although it makes sense<br />

for Singapore and London to achieve<br />

high percentages of green buildings<br />

from the built stock since they both<br />

rank first and second respectively<br />

on total number of green buildings<br />

(Figure 8), Paris’ result (Figure 9) can<br />

be questioned as the city does benefit<br />

from having the lowest number of total<br />

buildings (Figure 7). For those that<br />

may claim that Singapore performs<br />

particularly well because it is a relatively<br />

small city, Figure 8 quickly lays those<br />

arguments to rest; Singapore has the<br />

highest number of absolute green<br />

buildings with 2,339 Green Buildings<br />

built to date, outperforming London by<br />

35%.<br />

The disparity between those top<br />

three cities mentioned above and<br />

cities following them is high. As such,<br />

the percentage of Green Buildings in<br />

Shanghai, which comes fourth after<br />

Singapore, is 15%. The fifth city in the<br />

rank is also Chinese: Beijing with 11%<br />

of the total number of green buildings.<br />

Dubai, Tokyo, Sydney, and New York<br />

City come as the next, whereas Hong<br />

Kong complete the list with the lowest<br />

percentage (4%). Having New York City<br />

and Hong Kong achieve the lowest<br />

ratings might be attributed to the fact<br />

that they both have double or triple the<br />

average total number of buildings in the<br />

other cities (Figure 7), knowing that they<br />

come in fourth and fifth place when<br />

ranked based on total number of green<br />

buildings (Figure 8). Another reason<br />

could be the fact that those cities have<br />

been focusing on constructing new<br />

green buildings, without placing much<br />

effort on retrofitting existing buildings.<br />

“The current green building development has been focused on new buildings<br />

but is shifting towards existing buildings. For significant progress, the focus<br />

of stakeholders in Hong Kong should shift from new to existing buildings<br />

which make up the bulk of the building stock. Potentially, more effort can be<br />

made to incentivize sustainability for existing buildings, promote microgrid<br />

/ renewable systems to reduce dependence on coal-powered electricity, and<br />

divert waste from precious landfill space.”<br />

Cities such as London, New York and Hong Kong, which have<br />

adopted their own rating tools in the 1990s, accordingly<br />

have the largest ‘locally certified’ green buildings (Figure 11).<br />

The ranking based on the number of capita per green building (Figure <strong>10</strong>) did not show a large difference from the ranking<br />

cities based on the number of green buildings. The top three cities for green buildings – Singapore, London, and Paris –<br />

remained in the same position when compared on the population level, i.e. how many people are allocated to each green<br />

building. The only two cities that jumped in the ranking are Dubai and Sydney. This could be due to the fact that both cities<br />

have smaller populations in comparison to Hong Kong, New York, Shanghai, and Beijing. The number of capita per green<br />

building highlights cities that are making notable effort in building design and construction, as well as to create a healthier<br />

environment for inhabitants and workers. The indicator was not included in the methodology, but simply illustrates the ranking<br />

of the cities based on the number of capita per green building.<br />

The number of buildings certified locally<br />

versus those certified internationally<br />

vary slightly across the cities. The<br />

general pattern and trend is for cities<br />

to have a larger number of buildings<br />

certified locally instead of using<br />

international standards (Figure 12<br />

vs Figure 13). The only cities outside<br />

of the trend line are Paris and Dubai<br />

with the larger stock of buildings<br />

certified internationally than with locally<br />

developed standards (Paris using<br />

BREEAM primarily, and Dubai using<br />

LEED).<br />

This can be partially explained here.<br />

In the case of Paris, the small number<br />

of green buildings certified by HQE<br />

certification is believed to be due<br />

to the greater complexity of local<br />

versus international standards. HQE<br />

brings with it a greater number of<br />

requirements, whereas BREEAM and<br />

LEED certifications have far fewer<br />

requirements. Moreover, the BREEAM<br />

certification is less demanding about<br />

the integration of prerequisites, and<br />

processing times for the certification<br />

is more streamlined. One Paris-based<br />

green building professional reported<br />

that LEED and BREEAM certification<br />

applications can be sent via online<br />

platforms without on-site audits;<br />

On the other hand, HQE (Paris’ local<br />

certification system), requires on-site<br />

visits by HQE certifiers on up to 3<br />

separate occasions to conduct various<br />

audits.<br />

In the case of Dubai, it is largely<br />

explained by two factors. Firstly, the<br />

local Estidama Pearl Rating system is<br />

relatively new, having only launched in<br />

20<strong>10</strong>. Secondly, Estidama is a rating<br />

system developed by the Abu Dhabi<br />

Government, for the Emirate of Abu<br />

Dhabi. Abu Dhabi, being the capital<br />

of the United Arab Emirates, made<br />

Estidama available and recommended<br />

its use to all other emirates, including<br />

Dubai – but government regulations<br />

requiring the use of Estidama was only<br />

passed through Abu Dhabi’s policies.<br />

Having been left with the choice,<br />

Dubai continues to use international<br />

standards rather than subscribing to<br />

their neighbouring state’s certification<br />

process.<br />

“It is important to note<br />

that a building can be<br />

sustainable and incorporate<br />

green best practices without<br />

having a certification<br />

behind it. Certifications,<br />

however, are useful tools<br />

for measurement and can<br />

serve as guidelines for best<br />

practice. Nonetheless,<br />

Dubai does not have a<br />

specific certification or<br />

rating systems such as<br />

Estidama in Abu Dhabi, but<br />

the Leadership in Energy<br />

and Environmental Design<br />

(LEED) rating system<br />

is used and recognised<br />

broadly.”<br />

Whereas the ranking of Global Cities in the previous sections is based on the number of green buildings<br />

certified internationally and locally, the ranking in the data-set of Figure 14 is based on the number of<br />

Overall, there are more LEED accredited professionals than those upholding the BREAAM certification<br />

system, and there is a growing trend where locally credentialed professionals are increasing. Tokyo is the<br />

leader both in the total number of professionals, as well as in the normalized metric, which looks at the<br />

total number of credentialed professionals per building (Figure 15).<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings


Conclusion<br />

This chapter has assessed the green<br />

building landscape of each global city by<br />

measuring the number of green buildings,<br />

breaking down those green buildings by<br />

certification system type and evaluating<br />

the number of credentialed professionals<br />

per building. Overall, the trend is an<br />

increasing number of Green Buildings<br />

certified locally instead of internationally,<br />

and cities such as London, Singapore<br />

and Paris rank highest due to both high<br />

number of total green building projects<br />

in the city, and high percentage of green<br />

buildings as per total number of buildings<br />

in the city.<br />

GREEN BUILDING<br />

EFFICIENCY AND<br />

PERFORMANCE<br />

CHAPTER 5<br />

How efficiently do buildings in Global Cities perform?<br />

Buildings are a substantial element<br />

in every city. They are the largest<br />

energy-consuming sector worldwide<br />

– accounting for more than 40% of<br />

energy use and responsible for an<br />

estimated 30% of city-wide emissions.<br />

As a city commits to building green, it is<br />

important for it to set measurable goals<br />

for emissions and energy efficiencies,<br />

water conservation, and waste<br />

management in order to ensure that<br />

building projects are in fact contributing<br />

into enhancing the environment. The<br />

previous chapter evaluated the number<br />

of ‘certified green buildings’ each city<br />

had, and whether they were to a local<br />

or international standard.<br />

This chapter steps in to evaluate,<br />

regardless of the number of certified<br />

green buildings in the city – the overall<br />

efficiency and performance of the built<br />

stock in each city. The efficiency and<br />

performance of the built environment<br />

in each city involved zooming into<br />

2 major interrelated environmental<br />

impacts, namely, CO 2<br />

emissions and<br />

energy use.<br />

Space heating and cooling together<br />

with water heating are estimated to<br />

account for nearly 60% of global energy<br />

consumption of buildings. CO 2<br />

from<br />

energy use is the dominant factor<br />

leading to greenhouse gases emitted<br />

in the buildings sector. Water use was<br />

also an indicator, which was evaluated,<br />

but the lack of data and inconsistency<br />

of city-wide data led to the removal of<br />

this metric.<br />

“Globally, buildings account for 40% of energy consumption and 30% of carbon emissions.<br />

There is a real need for the building industry to undertake greater environmental<br />

responsibility and mitigate the impact of our activities on the environment. Moreover, we<br />

also witness that there is a strong business case for sustainability. This has been proven<br />

as integrating sustainability into our corporate vision and strategy has not only created<br />

long-term business value for CDL, but also for our investors and customers.”<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings


Paris, Sydney, and Singapore take the highest ranking spots with regards to each city’s green building efficiency. This is<br />

primarily due to the three cities not only being very low CO 2<br />

polluting cities in general, but also because they have a very low<br />

percentage of emissions which can be attributed to the city’s built-environment.<br />

How much CO 2<br />

do Cities’ Buildings Emit?<br />

While green building efforts are already underway for all of these Global Cities studied in this report, a majority of the top<br />

Global Cities emit relatively high levels of CO 2<br />

into the environment, with the exception of Paris and Sydney (Figure 17).<br />

Consequently, both cities also perform well in terms of CO 2<br />

emissions as a result of the built environment.<br />

By analyzing the carbon emissions per capita in the top <strong>10</strong> Global Cities (Figure 17); Paris, Sydney, and Singapore maintained<br />

their position as top performers and while Shanghai and Beijing recorded the highest CO 2<br />

emissions from buildings, they<br />

performed slightly better on this dimension, by ranking seventh and eighth on this metric. However, Dubai has a significantly<br />

higher carbon footprint per capita of (11.4MT) as energy consumption is high and its emissions are being spread among a<br />

small population.<br />

Carbon intensity is usually measured in terms of the CO 2<br />

emissions per dollar GDP. A city with low carbon intensity would<br />

mean that it is able to produce each unit of output with less CO 2<br />

emissions. Paris and Sydney remain undefeated as they also<br />

top the scale for carbon intensity of their building stock. Whereas, Singapore and Hong Kong that were in the top 5 for both<br />

CO 2<br />

emissions from buildings and CO 2<br />

emissions per capita, now find themselves ranked just before Shanghai and Beijing.<br />

Singapore has recently announced its goals to reduce emissions intensity by 36% from 2005 levels by 2030 and generally<br />

performs much better when compared as a country considering that it ranked 113th out of 140 countries, according to IEA<br />

Key World Energy Statistics in 2014.<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings 31


How much Energy do Cities’ Buildings consume?<br />

Paris and Singapore are amongst the best performers in how much energy is consumed from their buildings (Figure 18) – an<br />

indicator of the cities’ level of eco-consciousness and proof that both the local and international green building certifications<br />

used in both these cities are strong certification guidelines which push for greater greener building performance. This, of<br />

course, is the main goal. There may be cities where green building policies are in place, targets are set, local certification<br />

guidelines are created, but none yield strong green building performance in terms of efficiency of resource use and minimal<br />

negative environmental impact. In this light, the performance of the built-landscape in each city is the ultimate end-goal.<br />

Indeed, it seems as though the green building efforts in Singapore and Paris are working together, marking tangible progress,<br />

and are paying off.<br />

Shanghai accounts for the highest level of building energy consumption. New York follows in second place due to relatively<br />

high CO2 emissions from buildings, second highest size of built stock and second lowest percentage of total green buildings.<br />

When evaluating the per capita energy consumption from buildings, New York still comes as the first with the highest energy<br />

use by buildings, further followed by Dubai and Shanghai. Oppositely, Singapore and Tokyo exhibit the lowest building energy<br />

consumption level per capita, whereby the population sizes of the respective cities rank as the 8th and 3rd highest out of<br />

selected top <strong>10</strong> Global Cities (Figure 18).<br />

In part of energy consumption from buildings per GDP, which implies energy efficiency per unit of production, Shanghai and<br />

New York have the highest level, whereas Paris, Tokyo, and Singapore’s buildings consume the lowest level of energy in this<br />

category (Figure 18).<br />

Noticeably, Shanghai and New York do not fare as well in both normalized metrics in comparison to other cities. Under the<br />

City Building Energy Saving Projects Special Support Measures introduced in 2012, Shanghai’s government committed to<br />

provide energy monitoring and management to building projects, and promoting energy saving and green building features.<br />

New York City’s new plan, “One City, Built to Last: Transforming New York City’s Buildings for a Low-Carbon Future” announced<br />

in September 2014 seeks to reduce the carbon footprint of the city’s top greenhouse gases emitters - buildings, both public<br />

and privately owned. These efforts set out by both cities, if executed well and successful will likely materialize into substantially<br />

better results in coming years.<br />

How much Water do Cities’<br />

Buildings consume?<br />

Water consumption from buildings is an important<br />

metric that governments worldwide should take<br />

into consideration. The benefits of enforcing waterefficiency<br />

measures encompass water savings<br />

and achieving sustainability goals. Moreover, such<br />

measures will reduce buildings’ energy costs since<br />

heating water is associated with significant amount<br />

of energy use. Additionally, implementing waterefficient<br />

practices implies achieving green building<br />

certifications thereby fostering healthy green<br />

building movement. Recognizing the importance<br />

of water consumption from buildings, this metric<br />

was however not used in the ranking due to lack<br />

of available data (as only data for New York - 1235<br />

billion litres, Dubai - 267 billion litres, Sydney - <strong>10</strong>1<br />

billion litres, were found). As such, cities should do<br />

more to focus on the portion of water consumed<br />

from buildings, as it is just as important a resource<br />

as energy, if not growing in importance over time.<br />

Annex II includes a graph showcasing annual water<br />

consumption by city.<br />

Conclusion<br />

There are roughly 8 to <strong>10</strong> million new buildings<br />

constructed per annum worldwide, most of<br />

them in developing countries. According to the<br />

International Energy Agency, buildings account<br />

for up to 41% of global energy savings potential<br />

by 2035, compared with the industrial sector<br />

(24%) and the transport sector (21%). Attempts<br />

to improve energy consumption in buildings will<br />

ultimately lead to better levels of CO 2<br />

emissions.<br />

Thus, it is crucial for cities to intensify action<br />

plans aimed at greening the design of the built<br />

environment, so that buildings not only have less<br />

impact on the environment during construction,<br />

but most importantly, operate in a green and<br />

more efficient manner. Greening new buildings at<br />

the design stage is much easier than retrofitting<br />

existing buildings to operate more efficiently. For<br />

these reasons, green buildings are an important<br />

pillar to build more sustainable cities around the<br />

world.<br />

GREEN<br />

BUILDING<br />

POLICIES AND<br />

CHAPTER 6<br />

TARGETS<br />

As covered in the previous chapter,<br />

buildings have wide-ranging direct and<br />

indirect impacts on the environment.<br />

Given the long lifespan of most buildings,<br />

decisions made on the design and<br />

construction of a building during its project<br />

phase will determine its consumption<br />

and impacts over its lifetime. This has<br />

then prompted the inception of green<br />

building standards, certifications, and<br />

rating systems targeted to alleviate a broad<br />

range of environmental issues through<br />

sustainable and greener designs.<br />

For this reason, green building codes<br />

and targets are imperative in a city’s<br />

journey towards greater adoption of<br />

Green Buildings. They act as a guideline<br />

to demonstrate and inform the respective<br />

stakeholders on essential elements to<br />

building green and the crucial steps to<br />

execute such initiatives within a specific<br />

timeframe.<br />

How supportive is your Government towards<br />

Green Buildings?<br />

Singapore is the standout leader in the Green Building Codes and Targets<br />

assessment. While all the Global Cities have outlined city-level green<br />

building codes, only three cities have achieved their green building targets.<br />

Singapore, Beijing and Shanghai are the only cities with both a green<br />

building code and green building targets set-out by the city.<br />

What Policies and Targets are Global Cities<br />

setting directly related to Green Buildings?<br />

Local and regional governments are uniquely positioned to implement<br />

policies that influence the commitments towards sustainability measures in<br />

the building sector, and to encourage its corporate citizens to build green,<br />

and citizens to live green. As such, city-level green building policies were<br />

researched for each city. Two metrics were considered in ranking the cities<br />

on the Green Building Culture dimension – the existence of green building<br />

codes and the existence of green building targets.<br />

Amongst the Global Cities in this study, Tokyo took the chronological lead<br />

with its Green Building Program having been issued in 2002; Tokyo’s Green<br />

Building Program began to take responsibility for the impacts its buildings<br />

had on the environment by requiring that newly built or extended buildings<br />

submit their building environment plans. In 2006, Singapore then launched<br />

its green building policy to spearhead the delivery of green buildings and<br />

concentrated on new buildings and those undergoing major retrofitting. The<br />

newbies in the green building agenda would be Beijing and Shanghai with<br />

recently issued action plans in 2013 and 2014 respectively.<br />

“Tokyo and Singapore are two progressive Asian<br />

cities in terms of green building development.<br />

Tokyo is pretty unique with its cap-and-trade<br />

program covering even large-scale office buildings.<br />

This controls carbon emissions at the source.<br />

Furthermore, development in green building<br />

technologies are at the forefront. Singapore has<br />

mandated energy efficiency standards and energy<br />

audits for existing buildings and provided financial<br />

incentives for the upgrades. The new smart nation<br />

agenda is also interesting with its well thought out<br />

vision and extensive scale.”<br />

TOKYO<br />

Green Buildings Policy Overview<br />

The submission system of “Building Environment Plan”,<br />

introduced in 2002, was designed in Tokyo to clarify<br />

environment-friendly approaches to buildings and highly<br />

evaluate excellent approaches. The system was introduced<br />

in June 2002 with the aim of creating a market where<br />

environment-friendly and high-quality buildings are<br />

evaluated. It is required for those newly built buildings<br />

or extended and whose total floor area exceeds 5,000<br />

square meters to submit their building environment plans,<br />

which evaluates four points: “streamlining of energy use,”<br />

“appropriate utilization of resources”, “protection of natural<br />

environment” and “mitigation of heat island phenomenon”.<br />

Energy Efficiency policies<br />

The Tokyo Cap-and-Trade Program, launched in 20<strong>10</strong>, is<br />

one of the worldʼs first programs which covers buildings and<br />

facilities in cities such as offices and commercial buildings<br />

and mandates total reduction of CO 2<br />

emissions from large<br />

facilities (accounting for approximately 40% of emissions<br />

from the city’s industrial and commercial sectors). A target to<br />

be achieved by the relevant sectors has been established as<br />

a cap (emission limit) taking into account the 2020 reduction<br />

target for Tokyo as a whole, and a mandatory reduction rate<br />

has been set for each facility based on the cap. Each facility<br />

is obliged to reduce the aggregate total of emissions for the<br />

five years from 20<strong>10</strong> to 2014 (the first planned reduction<br />

period) by 8% or more (for office buildings, etc.) or 6% or<br />

more (for plants, etc.), compared with the amount obtained<br />

by multiplying the baseline annual emission amount by five.<br />

Owners of facilities will reduce CO 2<br />

emissions by introducing<br />

energy-saving measures and renewable energy in their<br />

own buildings, as well as by applying credits such as excess<br />

reductions and renewable energy credits purchased from<br />

other facility owners to their own reductions.<br />

Energy benchmarking / Disclosure<br />

of information<br />

Under the Evaluation and Publication Programme of<br />

Environmental Performance of new buildings, all large newly<br />

constructed buildings in Tokyo are obliged to conduct an<br />

environmental performance evaluation and publish the<br />

building environmental plan, which indicates the evaluation<br />

results. The system requires building owners to adopt<br />

environmentally conscious designs based on guidelines set<br />

down by the government, with the aim of creating a market<br />

where environmentally friendly buildings are highly valued,<br />

through publication and disclosure of their environmental<br />

performance.<br />

Financial incentives<br />

In Tokyo, tax incentives have been made available through<br />

the Energy Saving Promotion scheme targeting small to<br />

medium enterprises. These incentives exempt individuals and<br />

corporations from the enterprise tax when they introduce<br />

energy efficient equipment and renewable energy projects.<br />

SINGAPORE<br />

Green Building Policy<br />

Overview<br />

In 2005, the Singapore Government’s<br />

Building and Construction Authority<br />

(BCA) launched the Green Mark<br />

scheme, a leading green building rating<br />

system, serving as a benchmark tool for<br />

evaluating environmental sustainability<br />

in buildings. The main purpose was<br />

to encourage stakeholders to start<br />

building and living green. Thereafter,<br />

the city launched its first, second, and<br />

third Green Building Masterplans,<br />

which currently focus on driving the<br />

green building agenda by:<br />

1. adopting green building as the<br />

norm for new projects, and<br />

2. greening existing buildings, and<br />

3. focusing on both the hardware and<br />

software of the built environment<br />

(i.e. energy efficiency of buildings<br />

as well as the occupants’ behavior)<br />

4. setting Singapore as the leader<br />

in green building and sustainable<br />

development<br />

In 20<strong>10</strong>, with the launch of the City’s<br />

Sustainability Blueprint, Singapore<br />

set an ambitious target of greening<br />

80% of its building stock by 2030 in<br />

order to accelerate the green building<br />

agenda. By 2014, more than 25% of<br />

the city’s entire built-stock were already<br />

‘greened’.<br />

The target is set to be achieved by<br />

supporting the advancement of green<br />

building within the region, raising<br />

the community’s engagement and<br />

encouraging all stakeholders to get<br />

involved in greening the city, and<br />

sustaining constant monitoring of<br />

energy consumption, and seeking<br />

solutions for enhancing the well-being<br />

of people, and the quality of the built<br />

environment.<br />

Energy Efficiency<br />

policies<br />

Demonstrating building energy<br />

performance has become vital in<br />

Singapore to ensure an improved<br />

quality of the built environment.<br />

Existing buildings must comply with<br />

high energy standards and optimally<br />

operate after undergoing retrofit.<br />

Periodical energy efficiency audits<br />

are required, to ensure existing<br />

buildings comply with the minimum<br />

environmental sustainability standards<br />

under the Green Mark scheme.<br />

Energy Benchmarking<br />

/ Disclosure of<br />

information<br />

Singapore acknowledges the<br />

importance of energy and green<br />

building data sharing within the<br />

industry, and ensures transparency<br />

in the performance results. As of<br />

2012, Singapore set requirements for<br />

existing building owners to submit<br />

annual reports regarding their<br />

building information and its energy<br />

consumption through the Building<br />

Energy Submission System (BESS). This<br />

plan is beneficial to many stakeholders:<br />

• It serves the government as it is<br />

used as a way to monitor energy<br />

consumption and energy efficiency<br />

of buildings, thereby providing<br />

insights to BCA in the formulation<br />

of green building policies and<br />

energy performance monitoring<br />

strategies<br />

• It benefits owners and tenants by<br />

creating awareness on the energy<br />

performance of their buildings<br />

and helps them set measureable<br />

targets to improve energy<br />

efficiency of those buildings<br />

• It allows architects, engineers<br />

and other consultants to rethink<br />

their designs and incorporate<br />

best-in-class practices in design<br />

and retrofit of green buildings.<br />

Research and education<br />

communities can also benefit<br />

through data sharing and applied<br />

research to further advance green<br />

building technologies and solutions<br />

for the future<br />

Financial incentives<br />

There has been several Green Mark<br />

Incentive Schemes (GMIS) rolled out<br />

by the Building and Construction<br />

Authority (BCA) over the years, with the<br />

Green Mark Gross Floor Area Incentive<br />

Scheme being the most impactful for<br />

new developments as it drives new<br />

and existing private developments to<br />

undertake substantial energy efficiency<br />

enhancements in efforts to earn high<br />

Green Mark ratings. Other major<br />

schemes in play include its USD 50<br />

million and USD <strong>10</strong>0 million GMIS to<br />

encourage existing building owners<br />

and tenants to improve the energy<br />

consumption of their buildings and<br />

premises. Moreover, the Building<br />

Retrofit Energy Efficiency Financing<br />

(BREEF) Scheme financing programme<br />

introduced in collaboration with several<br />

Financial Institutions provide support to<br />

its building owners in overcoming the<br />

high upfront cost of carrying out energy<br />

efficiency retrofits.


PARIS<br />

Green Building Policy Overview<br />

Thirty large businesses have signed Paris Climate Action<br />

Charter initiated by the city authorities thereby undertaking<br />

steps to realize aims of Climate-Energy Plan. Under this<br />

charter, the Paris District Heating Company supplying 1/3 of<br />

public heating launched a programme to reduce pollution<br />

and promote renewable energies. By 2020, more than<br />

500,000 tonnes of CO 2<br />

will be reduced in the city every year.<br />

Built on the initiative of the City of Paris to assist in achieving<br />

the goals of the France Climate Action Plan, the Paris Climate<br />

Agency has been providing the support to the stakeholders’<br />

projects on green action. For instance, Lumo, a platform for<br />

responsible investment in renewable energy projects, has<br />

been developed in partnership with local authorities.<br />

Paris has also started the plan of one thousand buildings’<br />

energy renovation set to complete by 2020. This involves<br />

supporting building owners in their efforts to reduce<br />

Greenhouse Gas Emissions (GHG) and energy consumption<br />

through trainings spreading the word about ways to reach<br />

greener buildings while taking into consideration affordability.<br />

Moreover, under the environmental law approved by French<br />

parliament on March 19, 2015, the rooftops on all new<br />

buildings built in commercial zones in Paris must now be<br />

partially covered in plants or solar panels aiming to reduce<br />

heat and cooling energy consumption by buildings.<br />

In 2012, Paris introduced regional energy and air quality<br />

guidelines aligned with three following goals of Energy Action<br />

Plan for 2020:<br />

• Improve buildings’ energy efficiency, with a target<br />

of doubling the pace of non-residential building<br />

refurbishment and tripling it for residential buildings<br />

• Develop district heating powered by renewable and<br />

recovered energies, with a target of increasing the<br />

number of connected equivalent housing units by 40%<br />

• Reduce GHG emissions from road traffic by 20% in<br />

combination with a significant reduction in air pollutants<br />

Energy Benchmarking / Disclosure<br />

of information<br />

Every five years since 2004, the city authorities conduct<br />

GHG inventory and energy consumption assessments<br />

of government and community. In addition, an annual<br />

assessment of the implementation of the climate action<br />

plan is realized. The data on performance and practical<br />

achievement along with budget spent is published in the<br />

“Bleu Climat” report every year.<br />

Financial incentives<br />

Every year the City of Paris invests around USD 44 million<br />

in retrofitting residential buildings. Paris also supports<br />

green initiatives providing loans to green entrepreneurial<br />

companies and low rent fee spaces to install green activities.<br />

Energy Efficiency policies<br />

Under the Energy Plan, Paris has renewable energy sources<br />

starting from January 2016.<br />

NEW YORK<br />

Green Building Policy<br />

Overview<br />

The City of New York was one of the<br />

first jurisdictions to concentrate on<br />

improving energy efficiency in existing<br />

buildings, and it now leads innovation<br />

in Green Building.<br />

With energy efficiency and conservation<br />

driving its main agenda, New York City<br />

(NYC) established an independent,<br />

non-profit financial corporation called<br />

the New York City Energy Conservation<br />

Code (NYCEEC) in 20<strong>10</strong> – to assist<br />

the city in implementing its Greener,<br />

Greater Buildings Plan (GGBP) while<br />

advancing the goals of PlaNYC.<br />

The GGBP, introduced in December<br />

2009, addresses benchmarking, energy<br />

audits and retro-commissioning, as well<br />

as the adoption of a new energy code,<br />

all working towards increased energy<br />

efficiency for the city. Local Law 86<br />

(LL 86), the local Green Building Law,<br />

establishes a set of standards for public<br />

design and construction projects.<br />

Energy Efficiency<br />

policies<br />

With ‘One City: Built to Last’, the city<br />

will target every public and private<br />

building that needs significant energy<br />

upgrades. It is an all-inclusive <strong>10</strong>-year<br />

plan targeted to improve the energy<br />

efficiency of the NYC’s buildings, and<br />

sets an ambitious goal to reduce the<br />

city’s building emissions by 30% by<br />

2025. To achieve this goal, the City<br />

intends to:<br />

1. Complete efficiency improvements<br />

in every City-owned building that<br />

has significant energy use and<br />

install <strong>10</strong>0 MW of onsite renewable<br />

power.<br />

2. Cost-effectively build highly<br />

efficient buildings, looking to<br />

Passive House, carbon neutral, or<br />

“zero net energy” strategies.<br />

3. Develop interim energy<br />

performance targets for existing<br />

buildings to be achieved through<br />

voluntary reductions and new<br />

regulations.<br />

Other measures such as LL86<br />

requires that projects (i.e. new<br />

constructions, additions and substantial<br />

reconstructions) receiving more than<br />

a specified amount of city funding<br />

achieve a LEED rating level of certified<br />

or Silver and/or reductions in energy<br />

cost and potable water use.<br />

Energy Benchmarking<br />

/ Disclosure of<br />

information<br />

The GGBP requires large commercial<br />

and multifamily buildings to benchmark<br />

their energy and water consumption<br />

with Energy Star where the data will<br />

be posted online by the city. Failure to<br />

comply will warrant a fine. Local Law<br />

87, also part of the GGBP, mandates<br />

that buildings over 50,000 gross square<br />

feet undergo periodic energy audit and<br />

retro commissioning measures.<br />

Financial incentives<br />

New York City is one of the national<br />

leaders in terms of providing incentives<br />

for energy efficiency, at approximately<br />

USD 250mil p.a. covering a variety of<br />

programs, including direct incentives<br />

for energy reduction and market<br />

transformation. Local utilities and the<br />

New York State Energy Research and<br />

Development Authority administer such<br />

programs.<br />

In addition, the New York State Green<br />

Building Tax Credit provides USD 25<br />

million in income tax credits over<br />

a nine-year period for owners and<br />

tenants of buildings, which meet<br />

energy, indoor air quality, materials,<br />

commissioning, water conservation,<br />

appliance, and size criteria. Low<br />

interest loans (i.e. 4% below market<br />

rates) are provided for energy efficiency<br />

measures and building materials<br />

that meet New York green building<br />

standards.<br />

Green Building Policy Overview<br />

The Building Design to Foster a Quality and Sustainable Built<br />

Environment (BDF QSBE) was introduced in April 2011 for<br />

all new building plans to promote energy efficiency, urban<br />

livability, building maintenance, environmental conservation<br />

and green features in buildings. BDF QSBE requires that<br />

all new buildings undergo the Hong Kong Green Building<br />

Council BEAM Plus assessment and designed in accordance<br />

with a package of green building measures to receive<br />

concessions for additional gross floor area (GFA).<br />

Launched in March 2013, HK3030 campaign targets a<br />

reduction of 52% in absolute electricity consumption<br />

compared to a BAU scenario, which essentially reduces 30%<br />

of the absolute building electricity consumption by 2030, as<br />

compared to 2005 levels. For government buildings, a 5%<br />

electricity reduction target by 2020 (2014 as base) is set.<br />

Energy Efficiency policies<br />

In October 1998, the Building Energy Codes laid out<br />

compliance standards for which subsequently required<br />

mandatory compliance with the enactment of Buildings<br />

Energy Efficiency Ordinance (BEEO). The BEEO requires that<br />

developers or building owners of newly constructed buildings<br />

ensure that building services installation comply with the<br />

design standards of the BEC.<br />

Energy Benchmarking / Disclosure<br />

of information<br />

The BEEO enforced a statutory requirement to perform<br />

energy audits every <strong>10</strong> years and that the first round of<br />

audits to be completed by September 2016 on owners of<br />

commercial and composite buildings. Further requirements<br />

mandate that the Energy Audit Form, which contains the<br />

annual energy utilization index of the past 12-month period<br />

be exhibited in a conspicuous position at the main entrance<br />

of the building.<br />

Financial incentives<br />

BEEFS, one of the largest government-funded energy saving<br />

schemes in the world provided USD 450mil to stimulate<br />

private sector building owners to invest in improvements.<br />

New matching schemes in operation from 2014 to 2018 by 2<br />

major electric companies will provide an estimated USD <strong>10</strong>0<br />

million to support energy saving projects.<br />

With BDF QSBE, building owners are incentivized to<br />

incorporate specific features such as sustainable building<br />

design guidelines on building separation, building setback,<br />

site coverage of greenery and energy efficiency of buildings in<br />

order to obtain a GFA concession of up to <strong>10</strong>%.<br />

is encouraged by the Green Organisations Programme,<br />

which focuses on incentivizing landlords to upgrade their<br />

buildings, improving buildings operations, and training staff in<br />

both the public and private sectors to educate them on the<br />

importance of reducing CO 2<br />

and consuming clean energy.<br />

Moreover, RE:FIT an award winning non-domestic retrofit<br />

programme, was introduced to encourage public buildings<br />

to consider retrofit projects and achieve financial savings.<br />

The city’s government has also set a national target requiring<br />

all new homes built from 2016 and all new non domestic<br />

buildings from 2019 to be zero carbon. Finally, developers<br />

of new buildings are to abide by the mayor’s energy policies<br />

of being lean, being clean and being green. This means<br />

DUBAI<br />

Green Building Policy Overview<br />

In 2012, Dubai Municipality (DM) launched the Green Building<br />

Regulations and Specifications code for public buildings and<br />

later in 2014 for private commercial buildings. The purpose<br />

of the code is to increase resource-efficiency of buildings<br />

and to support Dubai’s Strategic Plan. The green buildings<br />

in Dubai are also assessed in accordance with the Estidama<br />

Pearl Rating System. Although this system is designed by and<br />

tailored to the Emirate of Abu Dhabi (the country’s capital<br />

and home to the federal government), its principles and<br />

indicators are applicable to other Emirates such as Dubai as<br />

well.<br />

As per “greening” the existing old-aged built stock initiative,<br />

the local Green Building Council introduced the Technical<br />

Guidelines for Retrofitting Existing Buildings in 2015, which<br />

implies refurbishment works with the purpose of increasing<br />

energy and water efficiency.<br />

In terms of the city’s Green Building achievements, Dubai has<br />

managed to – in a short period of time - green 8.4% of the<br />

city’s built stock via international rating and certification tools<br />

as well as the local Estidama Pearl Rating system. The city also<br />

has the world’s largest LEED Platinum government building<br />

which achieved 66% reduction in energy consumption and<br />

48% reduction in water consumption.<br />

• Encourages government-invested and public buildings sized >20,000 m 2 to follow the requirement of China Green<br />

Building Standards 2-Star or above.<br />

• Promotes the development of green eco-demonstration areas such as the Future Science and Technology City.<br />

During the period of the 12th Five Year Plan from 2011 to 2015, Beijing plans to construct at least ten ecological<br />

demonstration zones. All buildings within these zones must meet a minimum 1-star certification; with at least 40% of the<br />

buildings achieving a 2-star level or higher.<br />

Financial incentives<br />

The Chaoyang District in Beijing recently included LEED certifications to their existing incentive structure in which LEED Gold<br />

buildings will receive a one-time incentive of USD1.53/square meter of certified space, and LEED Platinum buildings will receive<br />

USD 3.06/square meter of certified space. Subsidies are also offered for 2-star and 3-star certified project amounting to USD<br />

3.44/square meter and USD6.12/square meter respectively. For both 1-star and 2-Star certifications in the aspects of design<br />

and operation, subsidies ranging from USD 1.2 thousand to USD 1.5 thousand are offered per project.<br />

SHANGHAI<br />

Green Building Policy Overview<br />

In 2011, the City of Shanghai was the first city in China<br />

to launch a “green standard” in construction to facilitate<br />

the promotion of energy efficiency and is actively working<br />

towards China’s 2020 aim to green at least 30% of new<br />

buildings constructed from 2012. Introduced in mid 2014,<br />

the Shanghai Municipality 3-Year Green Building Action Plan<br />

(2014-2016), in principal requires:<br />

• New civil buildings be constructed in accordance with<br />

green building standards 1 Star and above, and<br />

• Large public and government office buildings sized<br />

above 20,000 square meters to be constructed in<br />

accordance with green building standards 2-Star and<br />

above.<br />

Enforced on all new and existing buildings, initiatives such<br />

as Special Planning Shanghai’s Green Building and Eco-City<br />

comprises of government policies, plans and regulations, and<br />

professional guidance.<br />

Energy Efficiency policies<br />

The various energy management policies in place include:<br />

• Shanghai City Building Energy Saving Projects Special<br />

Support Measures (2012) – inclusive of ways the<br />

government will provide energy monitoring and<br />

management to building projects, and offered subsidies<br />

in effort to promote energy saving, green building<br />

features.<br />

• Regulation of Shanghai Building Energy Conservation<br />

(2011) encompasses the most comprehensive energy<br />

policies for the building sector in Shanghai.<br />

• Shanghai Energy-Efficient Building Design Standards<br />

guide encourages contractors to use energy-efficient<br />

materials and to adopt energy saving technologies for<br />

heating, cooling, ventilating, and lighting public buildings.<br />

Energy Benchmarking / Disclosure<br />

of information<br />

Systematic monitoring of green building standards is in place<br />

and energy audits are conducted. In addition, public buildings<br />

are required to implement sub-metering, and monitor<br />

and report its energy consumption data to the Municipal<br />

Construction and Transportation Committee.<br />

Financial incentives<br />

The Shanghai government will be investing up to<br />

approximately USD 1.29 million in subsidies which will be<br />

awarded to buildings with green features including China<br />

Green Building Label certified projects, prefabricated<br />

projects, new and existing buildings with high energy<br />

efficiency, on site renewable energy, amongst many.<br />

Conclusion<br />

This chapter has laid out the major, notable policies/codes, targets, and incentives<br />

developed by the <strong>10</strong> cities in our study. Each city has established its own targets<br />

and an accompanying policy or action plan to serve as guiding principles to<br />

support and grow its number of green buildings and reduce its environmental<br />

footprints.<br />

Tokyo began its green building journey in 2002 (the earliest of all <strong>10</strong> cities) and<br />

introduced a ‘Cap-and-Trade Program’, the world’s first carbon trading scheme, in<br />

20<strong>10</strong>. Today, the program is being replicated in neighbouring Asian governments<br />

and continues to spark interest in surrounding Metropolitan areas. Despite its<br />

early start, Tokyo’s green building landscape and performance rank below cities<br />

such as London, Singapore and Paris. Findings from ‘An Analysis of Comprehensive<br />

Effectiveness of Tokyo’s Climate Policies’ (Kamei, 2013) put forward certain reasons<br />

- generally, little information have been provided to building owners to employ<br />

energy-efficiency equipment and latest green technologies for their buildings,<br />

there has been a lack in subsidies for building owners to upgrade the facilities and<br />

while CO 2<br />

emissions from a building heavily relies on the energy use of tenants,<br />

this policy centers around building owners.<br />

New York has numerous initiatives enabling its green building movement but<br />

its GGBP has become one of the most comprehensive sets of energy efficiency<br />

policies in the United States, and targets the City’s largest existing buildings.<br />

However, the City is also trailing behind on its green building landscape and<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings 49


Singapore’s success in its green<br />

building agenda can be attributed<br />

to being a pioneer in the industry<br />

coupled with having put in place a set<br />

of comprehensive and bold policies<br />

for the construction of its buildings.<br />

By 2008, the City amended its<br />

Building Control Act, requiring all new<br />

construction and retrofits of existing<br />

buildings to achieve, at minimum, a<br />

Certified rating under the Green Mark<br />

Scheme. It’s Green Building Masterplan<br />

is comprised of policy instruments<br />

designed to enforce minimum<br />

environmental standards for building<br />

codes, stimulate the private sectors,<br />

promote research and development<br />

in environmental sustainability and<br />

grow Singapore’s appetite for green<br />

buildings.<br />

performance possibly because, like<br />

Tokyo, it is one of the largest and oldest<br />

mega-cities in our list of Global Cities;<br />

in addition, most of NYC’s initiatives<br />

have only targeted large buildings,<br />

casting aside ~50% of the city’s floor<br />

space – mainly residences and small<br />

business, where opportunities for<br />

energy reduction are also plentiful.<br />

Also, beyond meeting the NYC Energy<br />

Conservation Code requirements in<br />

force at the time of renovations by<br />

2025, there is no obligation to make<br />

any capital improvements based on<br />

the energy information generated.<br />

With that said, ‘One City: Built to Last’,<br />

a comprehensive <strong>10</strong>-year roadmap<br />

spanning 2015 to 2025 aims to target<br />

every public and private building<br />

requiring energy upgrades and<br />

might be just what the City needs to<br />

instigate a significant change in its<br />

environmental impacts.<br />

While Beijing and Shanghai newly<br />

joined the green building movement<br />

in 2013 and 2014, their results are<br />

already apparent in their total green<br />

building area. In Q1 2015, both cities<br />

were the top 2 out of <strong>10</strong> cities in<br />

terms of green building area (nearly<br />

20 million sq. m.), surpassing major US<br />

cities such as Chicago, New York and<br />

Washington D.C. They also managed to<br />

achieve a higher-rating (LEED and local<br />

certifications) green building area of 14<br />

million sq. m. taking up approximately<br />

75% of total green building area.<br />

Attempting to compare and rank the<br />

numerous codes, incentives and targets<br />

across cities would pose a challenge<br />

due to the volume and diversity of such<br />

initiatives. However, the effectiveness<br />

of policies and targets can be linked to<br />

and determined by the performance of<br />

the city in terms of the rate of adoption<br />

of green buildings (i.e. Green Building<br />

landscape), and the performance of<br />

green buildings in the city (i.e. Green<br />

Building performance and efficiency),<br />

and the performance of the city on the<br />

overall green level (i.e. Green Culture<br />

and Environment) as respectively<br />

described in previous chapters, and the<br />

following one.<br />

CHAPTER 7<br />

GREEN CITY<br />

CULTURE &<br />

ENVIRONMENT<br />

Do Global Cities enable a<br />

Green Building Agenda by<br />

Fostering a “Green City”<br />

Environment?<br />

Sustainability is at the core of economic,<br />

social and environmental initiatives<br />

worldwide. Green buildings result in<br />

energy and water efficiency and saving,<br />

while further decreasing the impact on<br />

the environment. This, in turn, fosters the<br />

productivity, creativity and innovation in the<br />

cities’ community. As such, the community<br />

with developed green city culture and<br />

environment will further streamline the<br />

sustainability efforts to increase the total<br />

number of green buildings. As a result, it is<br />

a circle where the sustainable environment<br />

and communities’ commitment to it are<br />

intertwined, the latter serving as the driving<br />

force.<br />

Thus, this chapter looks at whether cities<br />

adopt a climate action plan, have set targets<br />

to reduce their CO 2<br />

emissions, and evaluates<br />

whether they are actively addressing waste<br />

and energy by implementing green solutions<br />

such as waste recycling and renewable<br />

energy technologies.<br />

In ranking of this category, the ‘usual<br />

suspects’ in global green city rankings come<br />

to the forefront. Sydney, Paris and New York<br />

take the top 3 spots, and Singapore is just<br />

shy in 4th place.<br />

Once metrics are looked at individually, the<br />

top performers are somewhat scattered.<br />

Sydney and Paris, in particular perform<br />

well in terms of having single digit citywide<br />

CO 2<br />

emissions, with 6 and 7 million<br />

metric tonnes, respectively. New York is<br />

the standout renewable energy performer<br />

with the 17% of the city’s energy coming<br />

from renewable sources. Sydney is the<br />

clear winner when it comes to recycling;<br />

Sydney recycles nearly 70% of the city’s<br />

waste. Finally, surprisingly, the 3 Chinese<br />

cities ranked in the top 3 when it came to<br />

CO 2<br />

reduction targets, aiming to reduce CO 2<br />

emissions by over 3% per annum.<br />

Climate Action Plan<br />

A Climate Action Plan is a set of strategies<br />

aiming to embark upon sustainability and<br />

climate change action. Its primary goal is to<br />

guide the efforts and keep the city on the<br />

path of carbon emissions reduction. Since<br />

such goal means shifting from a fundamental<br />

patterns of urban development, buildings<br />

and consumption, the Climate Action Plan<br />

goes far beyond CO 2<br />

reduction.<br />

Actions to improve a city’s building energy<br />

and water use efficiency ultimately leads<br />

to a city’s greater resilience to the impacts<br />

of climate change. The top <strong>10</strong> Global Cities<br />

listed have each outlined the steps of the<br />

plan such as renewable energy use in<br />

power plants, transportation, and buildings,<br />

reduction of energy waste and greenhouse<br />

gases.<br />

Mode Gakuen Cocoon Tower, Tokyo, Japan<br />

Chinese cities Beijing and Shanghai, despite<br />

the absence of Climate Action Plans set,<br />

have adopted policies in line with the goals<br />

of Climate Action Plan. For instance, Beijing<br />

has set Clean Air Action plan, which tackles<br />

transportations’ carbon emissions. The city<br />

will also shut down 2,500 polluting firms in<br />

2016 aiming to shift from coal consumption<br />

to clean energy.<br />

CO 2<br />

emissions<br />

Global CO 2<br />

emissions mainly reflect the world’s fossil energy consumption and make up a substantial<br />

65% of total greenhouse gas emissions. Plotting out the emissions of the <strong>10</strong> Global Cities in Figure 23,<br />

Beijing and Shanghai rank the lowest due to the cities’ significant contribution of CO 2<br />

emissions, while<br />

Sydney and Paris take the lead with much lower quantity of emissions – approximately 6 and 7 million MT<br />

in 2014/15.<br />

By normalizing the CO 2<br />

emissions per capita and per GDP (Figure 23), Sydney, and Paris remain as top<br />

performers. However, while New York and Tokyo show more positive performance after normalization,<br />

Hong Kong, Singapore, and Dubai exhibit poor per capita performance in comparison with the other<br />

cities.<br />

According to IPCC, to limit global warming to 2°C as agreed on by the world’s governments at a 2009<br />

meeting in Copenhagen, global GHG will need to be reduced by 40% to 70% by 2050. In response, the<br />

top <strong>10</strong> Global Cities have pledged to reduce, or limit the growth of emissions by setting respective CO 2<br />

reduction targets to be achieved within the coming years (Figure 24).<br />

To address the high levels of city-wide emissions in Beijing and Shanghai, the cities established relatively high targets to be<br />

achieved within a 5- to <strong>10</strong>-year period amounting to more than 3.5% per annum. At the other end of the scale are Singapore,<br />

New York and London with reduction targets of 1% p.a. and lower.<br />

Waste recycling<br />

Waste recycling is becoming crucial for sustaining the environment and avoiding extra pollution of the city. It helps in saving<br />

resources and energy, generating revenues and minimizing landfill costs. Governmental institutions, private businesses, and<br />

residents are all responsible of keeping their surrounding clean with minimal effect on the environment. This is why many<br />

cities are proposing new initiatives concerning waste recycling and management.<br />

For the purpose of our study, current performance of the <strong>10</strong> Global Cities on waste recycling was assessed to identify which<br />

cities are taking action on this matter.<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings


Sydney and Singapore topped the list by achieving respectively high percentages of recycled waste (68%<br />

& 60%). In fact, Sydney set an interim waste strategy which purpose is to provide sustainable waste and<br />

recycling services through 2030. It includes six key focus areas: (1) producing less waste, (2) maximizing<br />

resource recovery, (3) having green infrastructure integration, (4) reducing greenhouse emissions, (5)<br />

introducing solutions for waste problems, and (6) cleaning the streets.<br />

As for Singapore, the city is following an integrated solid waste management system that concentrates<br />

on waste reduction, reuse and recycling. Waste-to-energy incineration plants are also adopted to reduce<br />

waste volume in the most efficient way.<br />

In comparison, the cities of Shanghai and Beijing scored the least among the <strong>10</strong> cities as they don’t show<br />

a clear plan for addressing waste recycling and reduction, and do not adopt a city-specific climate action<br />

plan.<br />

Consumption of Renewable Energy<br />

Renewable energy technologies are clean sources of energy which have a minimized impact on the<br />

environment than any traditional energy source. They are most of the times part of any city’s climate<br />

action plan, and considered as a good practice to reduce CO 2<br />

emissions. The <strong>10</strong> Global Cities were<br />

evaluated based on their consumption of renewable energy and results are shown in Figure 26.<br />

With constant and close coordination between the public and the private sectors, New York City<br />

managed to achieve the highest score for renewable energy consumption. Solar, wind, biomass and<br />

hydro are the renewable sources with the greatest short-term potential to provide significant amounts of<br />

energy for New York.<br />

Sydney is also putting lots of effort into adopting renewable energy technologies through its city master<br />

plan. In Beijing and Shanghai, efforts in renewable energy also involve heavy investments in wind farms.<br />

On the opposite side, Hong Kong and Dubai still have a long way to go, where the two cities’ use of<br />

renewable energy is very low. Recently, Dubai have committed to provide 5 percent of its energy demand<br />

from solar power by 2030.<br />

Waste Water Recycling<br />

Wastewater recycling is also worthwhile to look at when evaluating the city’s green culture. Wastewater<br />

can be an important and valuable source of alternative water. However, it demands appropriate<br />

management and processing before it can be reused due to contaminants. The given metric was not<br />

included in the ranking because the publicly available data is only at country level.<br />

Conclusion<br />

City-level green initiatives are essential<br />

for measuring the sustainability culture<br />

of the city, and how it fosters a green<br />

environment – which directly and<br />

indirectly enables the green building<br />

agenda. The top <strong>10</strong> Global Cities have<br />

adopted various policies and regulations<br />

in line with the goals of their individual<br />

Climate Action Plans. To reduce CO 2<br />

emissions, all <strong>10</strong> Global Cities have set<br />

targets to achieve within a period of time.<br />

London and New York started their CO 2<br />

reduction plans in the 1990s, which also<br />

explains how both do well on green city<br />

initiatives.<br />

New York performs particularly well in<br />

renewable energy consumption (#1) and<br />

London performs above average when<br />

ranked in their efforts for waste recycling<br />

and renewable energy consumption.<br />

Both Sydney and Hong Kong have set<br />

higher than average CO 2<br />

reduction<br />

targets amongst the <strong>10</strong> cities, and have<br />

also proven themselves as they perform<br />

noticeably well with low levels of city-wide<br />

CO 2<br />

emissions and high percentages<br />

of waste recycling. Cities like Beijing,<br />

Dubai, and Shanghai have newly joined<br />

the movement (in 20<strong>10</strong>), which explains<br />

why the three lag behind on the waste<br />

recycling metric, and for Dubai on the<br />

renewable energy consumption.<br />

“In SE Asia we see several ASEAN initiatives that will help<br />

in harmonizing policies which ideally approach similar<br />

corporate levels as the European Union. Renewable energy is<br />

becoming a larger part of the energy profile for cities. In the<br />

United States the U.S. Department of Energy’s (DOE) has<br />

implemented a Cities Leading through Energy Analysis and<br />

Planning (Cities-LEAP) program which is led by the National<br />

Renewable Energy Laboratory (NREL). This program looks at<br />

the Energy Profiles of 23,400+ U.S. cities and is focused on<br />

promoting more efficiency of the use of energy in cities.”<br />

Conclusion<br />

Green buildings presents itself globally<br />

as an opportunity for generating<br />

sustainable growth.<br />

When considering just some of the<br />

benefits of building green, it is easy<br />

to see why this is a strategic initiative<br />

worth pursuing for many cities and<br />

countries, which are trying to mitigate<br />

their negative footprint on the<br />

environment, reduce the operational<br />

costs of these cities, and sometimes<br />

add additional sources of revenue (e.g.<br />

eco-tourism, competitiveness, green<br />

job creation, etc.).<br />

This white paper compared the<br />

performance of ten Global Cities –<br />

Beijing, Dubai, Hong Kong, London,<br />

New York, Paris, Shanghai, Singapore,<br />

Sydney, and Tokyo – with regards to<br />

Green Buildings. Each of the cities<br />

were analyzed to assess each city’s<br />

green building policies and targets,<br />

adoption of green building certification<br />

and construction projects, and the<br />

efficient performance of the city’s built<br />

environment.<br />

The purpose of the paper was to<br />

benchmark and publish the green<br />

building performance of these<br />

Global Cities, in order to contribute<br />

to knowledge-sharing, reveal bestpractices,<br />

and better understand what<br />

is best working for cities on the global<br />

green building stage.<br />

This white paper has found Paris to<br />

be top ranking (1st) in its pursuit of<br />

developing a leading Green Building<br />

city. Paris is indeed excelling on Green<br />

Building efficiency and performance;<br />

this can be clearly observed from<br />

having the lowest CO 2<br />

emissions and<br />

energy consumption from buildings.<br />

Despite having normalized most of<br />

the metrics in this report by GDP and<br />

population, the fact that the city’s<br />

land area and population being the<br />

smallest and the GDP being the 4th<br />

largest among the <strong>10</strong> cities gives Paris<br />

an advantage. Small cities emit less<br />

CO 2<br />

and consume relatively less energy<br />

than other big cities, and tend to be<br />

more efficient.<br />

Paris also was the second city to<br />

perform well on the Green Culture<br />

and Environment dimension<br />

following Sydney. The city showed<br />

positive performance on city-wide<br />

CO 2<br />

emissions (2nd), city-wide CO 2<br />

emissions per capita (2nd), and<br />

city-wide CO 2<br />

emissions per GDP<br />

(1st). In fact, Paris clearly puts (1)<br />

GHG emissions reduction, (2) Energy<br />

consumption reduction, and (3)<br />

Renewable energy consumption at the<br />

center of its climate action plan.<br />

Unlike many cities in our ranking, Paris<br />

seems to focus all of its efforts on<br />

achieving the set goals by encouraging<br />

green urban planning, implementing<br />

strict regulations on buildings,<br />

and providing safe energy supply.<br />

Interestingly, Parisian developers seem<br />

to have a strong preference for the<br />

international BREEAM certification<br />

over the city’s local HQE green building<br />

standard for this very reason: HQE<br />

seemed to be more stringent, and<br />

more challenging to achieve.<br />

Instead of setting a target of greening<br />

a percent of its built stock in the future<br />

(i.e. focusing on the numbers), Paris<br />

has focused its effort on the endresult<br />

– setting quantifiable targets<br />

for energy efficiency and building<br />

performance. Many cities in our ranking<br />

still focus on activity-based goals (ie.<br />

number of green building certifications<br />

issued), rather than setting city-wide<br />

performance-based goals (% reduction<br />

of energy consumption by buildings).<br />

Singapore followed Paris, and ranked<br />

second overall. The city excels in its<br />

green building landscape, and green<br />

building policies and targets. In fact,<br />

both local and international certification<br />

standards in Singapore are yielding<br />

high-performance in green building,<br />

and proving to be efficient. Singapore<br />

has rapidly joined the green building<br />

movement to reach the largest number<br />

of certified green buildings – using both<br />

global (LEED and BREEAM) and local<br />

(Green Mark) certification systems,<br />

with over 2300 green buildings on its<br />

cityscape to date.<br />

Beyond the outstanding number of<br />

certified green buildings on Singapore’s<br />

skyline, the overall efficiency and<br />

performance of the built stock in<br />

Singapore is also performing strongly,<br />

indicating the city’s commitment to<br />

sustainable performance. Singapore,<br />

as a government, is clearly ecoconscious<br />

and committed to pushing<br />

and monitoring the green building<br />

agenda; this is illustrated by the strict<br />

72<br />

<strong>Top</strong> <strong>10</strong> Global Cities for Green Buildings


action plan being implemented which<br />

aims to green 80% of Singapore’s total<br />

built stock by 2030. The city is already<br />

encouraging all stakeholders to get<br />

involved in greening the city, monitoring<br />

energy consumption, and seeking<br />

solutions for enhancing the well-being<br />

of people, and the quality of the built<br />

stock.<br />

It is initially surprising that New York<br />

does not fare as well as expected on<br />

the Green Building metrics. Although<br />

the city possesses the 2nd highest<br />

GDP, it is far more densely populated<br />

in comparison to the other cities<br />

with similar land area. Firstly, when<br />

evaluated for its built stock, NYC<br />

showed that it still has a long way to<br />

go for greening its buildings (only 5%<br />

of the city built stock is green). NYC’s<br />

buildings also consume very large<br />

amounts of energy (80%) as well as<br />

emit a large volume of CO 2<br />

(74%),<br />

which explain the poor performance<br />

on the Green Building Efficiency and<br />

Performance dimension.<br />

However, NYC does manage to be in<br />

top 3 on Green City metrics. This is<br />

because the city performs exceptionally<br />

well on the renewable energy<br />

metric, and invests a lot of efforts on<br />

encouraging energy re-use. Moreover,<br />

although the city has one of the highest<br />

city-wide CO 2<br />

emissions figure (which<br />

can be attributed in part to its large<br />

population), this figure shows better<br />

results when normalized per capita and<br />

per GDP pushing NYC to top 5 on these<br />

metrics. It seems that NYC is indeed<br />

investing a lot of effort on greening<br />

the entire environment, but the city<br />

may require more focused attention to<br />

green buildings, as they still contribute<br />

the most to CO 2<br />

emissions and energy<br />

consumption. NYC has announced<br />

many sustainable city initiatives in<br />

recent years, which will take time to be<br />

implemented and to show performance<br />

gains in a report such as this; that said,<br />

it will be very interesting to see how<br />

NYC fairs in future rankings.<br />

In contrast to NYC, Sydney would have<br />

topped the list of Global Cities for<br />

green buildings if only it performed<br />

better on its built landscape. Sydney<br />

ranked first on green building culture<br />

and environment and managed to rank<br />

second on green building efficiency<br />

and performance, but does not have a<br />

strong number of green buildings on its<br />

skyline. Despite this, Sydney emits the<br />

least CO 2<br />

, recycles the most waste (as<br />

a percentage of total waste-to-landfill),<br />

and consumes more renewable energy<br />

than the vast majority of the other<br />

cities (with the exception of New York).<br />

Thus, Sydney was close to being in<br />

the top 3 if it did better on its green<br />

building landscape, but having only 6%<br />

of its total built stock “certified green”,<br />

totaling only 67 green buildings, Sydney<br />

slid in the rankings.<br />

Cities are making a lot of efforts in<br />

order to turn their built stock green,<br />

and many best practices are being put<br />

in place for other cities to learn from.<br />

For instance, Abu Dhabi has built the<br />

world’s most sustainable low-carbon<br />

city – Masdar City – which currently<br />

has one of the world’s largest efficient<br />

built-stocks, and is comprised of only<br />

certified buildings; Masdar is still in its<br />

infancy, but provides a glimpse into<br />

how future cities could be designed.<br />

Beijing has set interesting plans to<br />

construct ecological demonstration<br />

zones, within which all buildings must<br />

meet a specific certification standard.<br />

Dubai has launched the “Technical<br />

Guidelines for Retrofitting Existing<br />

Buildings” handbook in both English<br />

and Arabic, to educate owners,<br />

operators, and end-users on ways to<br />

reduce energy and water use, enhance<br />

the longevity of the building stock, and<br />

improve habitant’s well-being.<br />

Though energy efficiency and CO 2<br />

emissions are being measured by<br />

most Global Cities today, it was<br />

disparaging to find that water<br />

consumption figures were difficult to<br />

gather. Water is arguably the most<br />

precious resource on earth, and to not<br />

have city-wide consumption figures<br />

in 2014 is unacceptable. We look<br />

forward to future Green Building City<br />

Rankings which include water efficiency<br />

performance measures.<br />

Overall, the green building movement<br />

in the past <strong>10</strong> years has witnessed<br />

exceptional growth, and we have seen<br />

“new cities” such as Dubai, Singapore<br />

and Shanghai make significant gains.<br />

We have also seen older cities like NYC<br />

struggle with its old infrastructure and<br />

growing population. But Paris proves<br />

to us that old cities do not have to<br />

be trapped and weighed down by<br />

aging infrastructure; a strategic and<br />

methodical approach to retrofitting can<br />

dramatically improve efficiency.<br />

All in all, the intensifying efforts and<br />

action plans aimed at greening the<br />

built stock in a city is important, not<br />

only to reduce the impact on the<br />

environment during construction, but<br />

also for the buildings to operate in a<br />

green and more efficient matter. Green<br />

buildings are the pillars to building<br />

more sustainable cities around the<br />

world; and building more sustainable<br />

cities around the world is integral to<br />

achieving sustainable development<br />

and preserving our world’s resourcing<br />

for present and future generations.<br />

The Global Cities in our ranking shows<br />

us that the green building movement<br />

is alive and well, and that there are a<br />

myriad of approaches to building and<br />

greening a city’s built environment.<br />

There is no “right approach” and every<br />

city must adjust its strategy based on<br />

where in its sustainability journey each<br />

city finds itself. The key is to focus on<br />

driving gains in performance metrics,<br />

versus focusing and measuring green<br />

building activity alone. In the green<br />

building race, the end-result and bigpicture<br />

of living in sustainable, efficient<br />

and low-consumption cities is more<br />

important than how many buildings can<br />

be labeled as “green”.<br />
