Q3 2010 CES Energy Group Overview

Combined Heat and Power (CHP)Combined Heat and Power (CHP) is the use of a single process to simultaneously generate

both electricity and useful heat. It is one of the most common forms of energy recycling

Q3 2010 CES Energy Group Overview

Tri-Generation• Tri-Generation is the simultaneous production of electricity, heat and cooling from a

single fuel input • The "waste heat" by-product that results from power generation is harnessed, thus

increasing the overall efficiency of the system• A Tri-Generation system consists of a CHP engine/turbine and an Absorption Chiller

Q3 2010 CES Energy Group Overview

Why Tri-generation?• Tri-Generation offers a use for waste heat on a site when there is no heat demand• Below is a load profile of a typical commercial building showing high summer cooling

demand

Energy Concession Contracting€250M is wasted / year in office buildings in Dublin alone*

Many of the newest buildings are the worst offenders

80% of the buildings we will occupy in 2050 are standing today

In typical office buildings savings of 30 – 40% are achievable

Businesses are experiencing market cost pressures

Energy costs to increase substantially over the next 5 years

Future carbon taxes will further increase the cost of wasted energy

Wasted energy is wasted profits
