Careful design and ongoing management
can deliver efficiency savings of up to 50%
on existing energy overheads.
Reduce the reliance on supply utilities and
guard against rising energy costs.
Engines have been developed to run on
less carbon intensive fuels which have
environmental benefits as well as reducing
energy costs.
CHP is flexible with models that can be
wall hung in a utility room through to multi
megawatt energy centers of the type cho-
sen for the 2012 Olympic Games.

How system electrical efficiencies can vary by CHP type...
W HA T IS CHP?
Cogeneration or CHP is a
means for building owners and
managers to more efficiently use
available energy sources and
thereby reduce the overall de-
mand for energy.
W HICH BUILDINGS?
Buildings that benefit the most
shall have a reasonably constant
demand for energy such as
Schools with swimming pools,
Hospitals, Hotels, Leisure com-
plexes and heavy industry.
SOLVING THE PUZZLE
The central task for the engineer
is to gain an understanding of
the load profile and to closely
match the building demands with
the outputs of the CHP so that
maximum savings in energy are
achieved.
REPORT
Each project is considered indi-
vidually by a qualified engineer
and a report shall provide an
illustration of the potential for
savings.
IT’S ALL IN THE EFFICIENCY...
