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.

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...
