KREEN brochure - Kempinski Hotels

Power
of Nature
Conventional energies like oil and gas are becoming increasingly expensive.
Climate change also factors into increasing energy costs. The power of nature
is the solution for the future energy needs. Solar, geothermal, water and
wind power costs are decreasing in the future. Already today, clever, efficient
and renewable energy solutions make a difference in cost, sustainability and
environmental protection.

Powerful
Solutions
For Hotels
Existing hotels and hotels in planning,
design and construction phases will be
able to benefit from KREEN’s services.
KREEN’s services will initially be offered
only to Kempinski hotels.
KREEN offers consulting, planning, project management and
quality assurance services to Hotel Owners in the field of
renewable energies with the aim to:
Optimise the hotels’ energy management and the use of other resources
Generate financial savings through reduced operating costs
Enhance the hotels’ standing through compliance with the highest possible
environmental standards
Integrate energy management design into a new property from the start,
a new benefit for hotels

The choice of which
renewable source is
preferred depends on
the size of the complex
and the local natural
conditions.
Solar Energy
Solar power generators may produce most of the world’s
electricity within 50 years, dramatically reducing the emissions
of greenhouse gases that harm the environment.
Solar energy is still comparably expensive
in areas with low energy prices but
readily available in sunny regions. Solar
panels are getting more and more
efficient and prices fall with mass
production. Flexible and tinted panels
can be integrated in building facades to
support the architectural character of
the hotel complex.
Renewable Energy
Sources
Renewable energy sources can make the difference in
areas where they are easily accessible or conventional
resources are scarce or expensive. With growing energy
demand and rising costs they will be the power of the
future. A 100 % renewable world is inevitable. Not only do
a growing number of countries dare to make the change
but many have already achieved it.
More and more communities in Europe and all over the
world are 100 % renewable, using the different renewable
solutions – including hydro power, biomass, geothermal,
wind and solar power. A hotel can also be supplied
with 100 % renewable energies depending on the local
situation. Technologies to harvest renewable energy
sources are in continuous development for more efficient
and convenient solutions.

Hydro power
Energy in water can be harnessed and used. Even a slow-flowing
stream of water can yield considerable amounts of energy. There
are many forms of water energy.
Geothermal
Power
So-called small hydro power plants can be used almost everywhere, where a
flowing river with a sufficient head is present. The advantage of small hydro
power plants is their ability to operate year-round in moderate climates.
This energy derives from heat in the Earth´s
core. Where hot underground steam or water
can be tapped and brought to the surface it may
be used to generate electricity.
A deep geothermal power plant is only a
solution in certain volcanic areas where
the heat can be tapped using shallow
wells. The advantage is a year-round
availability. Ground-coupled heat pumps
use the constant temperature stored
in groundwater or solid rock. Constant
temperatures of 10 to 20 °C are harvested
and used by a heat pump to generate
heat and cold. The energy distribution
system of the hotel complex has to
be designed accordingly with supply
temperatures not higher than 55 °C. Floor
and wall heating and cooling systems
have to be applied.

Business Model
KREEN offers an individual project
development for each hotel.
The geographic setting of the hotel
complex, the local energy price and
the renewable energy supply define
the combination of renewable energy
solutions that meet the individual
hotel complex’s needs for electricity,
heat and cold. The renewable energies
can also be used for desalination.
In cases where renewable energies
are not readily available or the local
situation doesn’t allow their use,
combined heat and power plants use
conventional fuels as efficient as
possible. Cutting the costs of supply
by using the most efficient solution is
the core of our business model.
Wind energy
Wind power is growing at the rate of 30 %
annually, with a capacity of 198 gigawatts in
2010. It´s widely used in Europe and Asia.
Local wind source characteristics like wind speed and
duration are the basis of the design. For a hotel complex,
wind turbines, small or large, can only be one part of the
solution and therefore have to be combined with heatand
cold-producing sources.
Hotel Example in the
Middle East
Energy need:
Hot water supply and swimming pool heating
Existing Conventional System: Boilers operated with oil
Replaced by Solar Heating:
900 m 2 of solar collectors
Cost savings: 60 – 70 %
Payback:
less than 4 years

A Partnership between
Stadtwerke Mainz AG, Germany
Marshfield Energy Ltd, Singapore
Kempinski Hotels SA, Switzerland
Stadtwerke Mainz (public corporation, AAA rating), based in Germany and Marshfield, based in
Singapore, are leading specialists in the field of energy, related services and infrastructure. While
Marshfield is leading in geothermal energy, Stadtwerke Mainz is strongly focused on solar power
and, for example, has put in place the biggest photovoltaic installation in Africa. Both have a
strong track-record in bringing renewable energy projects to life, especially in Europe, Asia and
Middle East & Africa, which presents a great opportunity to all Kempinski hotels.
Kempinski will benefit from our partners’ specialised knowledge, resources and networks in
renewable energy, and gain access to suppliers of related products, systems and technology to
help hotels implement a comprehensive strategy for energy use.
