Group Activity

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

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

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

vii. Data centre example

CES Energy Concession Contracting
 Engineered energy efficiency
programs
 Provision of finance for
equipment upgrade programs
 No up front investment
required
 Energy Savings finance
improvements
 Partnership approach to
energy reduction
 Flexible contracts 3 – 15
years
 Diverting money already
being spent
Simply press start to reduce your energy costs

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
