Building energy efficiency and management for hotels - TERI

CRSBS (Centre for Research on Sustainable Building Science) has been set up
to facilitate development and mainstreaming of sustainable buildings, to improve
performance levels of existing buildings, and raise awareness on sustainable buildings.
CRSBS comprising architects, planners, engineers, and environmental specialists
has been offering environmental design solutions for habitat and buildings of various
complexities and functions for nearly two decades.
Services offered
• Environmental design consultancy
• Facilitation of GRIHA (Green Rating for Integrated Habitat Assessment)
• Energy audits and energy management programmes
• Awareness generation and capacity building
• Enabling policy, formulation of norms, and standards
• Climate change related projects
Environmental design consultancy
CRSBS provides specialized environmental design consultancy and building
performance analyses. Services offered for various green design projects include the
following.
• Design charettes and review
• Energy consultancy
• Renewable energy potential assessment and system design
• Building envelope study for shading, daylight, and material solution
• Artifi cial lighting optimization and daylight integration
• Water use estimation and water effi ciency calculation
• Landscape assessment for water effi ciency and rainwater-harvesting potential
• Appropriate waste management schemes and systems
• Evaluation of systems for on-site treatment of waste water
A wide range of computation and simulation tools including DOE2, TRNSYS, ECOTECT,
RADIANCE, AGI32, LUMEN DESIGNER, DesignBuilder, EnergyPlus, BLAST, and
RETScreen are used to assess the environmental and cost impact of the design
decisions. CRSBS has successfully provided environmental design consultancy to over
100 projects including institutional, residential, industrial, and commercial buildings
across the country.
Facilitation of Green Rating for Integrated Habitat Assessment
CRSBS provides consultancy for projects through various stages (that is pre-construction,
building planning and construction, and building operation and maintenance of any
building) towards compliance with the various GRIHA criteria.
CRSBS has facilitated GRIHA rating for over 30 building projects thus far.
Computer simulations are carried out for design assesment.

Energy audits and energy management programmes
CRSBS conducts energy audits and conservation studies to explore energy conservation
possibilities in commercial buildings such as hotels, hospitals, and offi ce complexes.
Detailed energy analysis of various energy systems (lighting, heating, ventilation, air
conditioning, water heating, and so on) through short-term monitoring are offered to
recognize areas of energy wastage and ways recommended and mitigate the same.
There is a pool of instruments such as digital lux meter, digital temperature indicator,
fl ue gas analyzer, anemometer, ultrasonic fl ow meter, hygrometer, and power analyzer
with data logging facility to facilitate audits and conduct monitoring studies. CRSBS has
conducted over 200 energy audits and management programmes thus far.
Awareness generation and capacity building
CRSBS also offers its services to develop and design websites, educational material
(books, brochures, and so on), and conduct workshops and training programmes to
generate awareness on the subject of green buildings and build capacity towards the
same. The team has developed the SHADA (Sustainable Habitat Design Adviser)
website, the Knowledge bank on Sustainable building design (an e-tool to enable
design, development and replication of sustainable habitats in a developing country),
and published several books and information brochures on techniques and benefi ts of
green and energy-effi cient buildings.
Enabling policy, formulation of norms, and standards
CRSBS conducts research on various aspects of policy formulation and implementation,
development of norms, guidelines, and frameworks for development with reference to
green buildings in India. CRSBS has developed the manual for environmental clearance
of large construction for the Ministry of Environment and Forests, EBRG (Environmental
Building Regulations and Guidelines) for Hyderabad Metropolitan Area, National Green
Building Rating System-GRIHA, contributed to the development and formulation of the
Energy Conservation Building Code (2007), Model Bye-laws and the National Mission
on Sustainable Habitats of the National Action Plan on Climate Change.
Research on buildings and climate change
CRSBS conducts research on Indian buildings and their impact on climate change;
for example the current CO 2 emissions from the building sector in India, the emission
reduction potential and the policies to facilitate environment-friendly buildings.
The team has conducted research on various aspects of buildings and climate change
with HSBC, United Nations Environment Programme, Asian Development Bank, the
World Business Council for Sustainable Development, and the Jawaharlal Nehru
National Urban Renewal Mission, among others. Under Asia Pacifi c Partnership on
Clean Development and Climate, high performance commercial buildings in India have
been defi ned along with impact assessment on emission reduction.

TERI buildings
> The TERI-RETREAT at Gual
Pahari in Gurgaon is the fi rst example
of a green building in the country.
This centre has become the role
model for all other green buildings
that have come up in the country.
This complex was inaugurated in
2000.
> The TERI Southern Regional
Centre at Bangalore is another
example of eco-friendly design for that
particular climatic zone. The daily per
square feet electricity consumption
of the complex is one-tenth that of a
conventionally designed complex.
> The new TERI-University campus,
Vasant Kunj, also has been designed
as per recommendation provided by
CRSBS. This resulted in reduction in
annual energy consumption by about
60% and reduction in annual water
consumption by almost 25%.
