CHP is at once generation of usable heat and power in a single process. Using an absorption cooling cycle (Trigeneration or CCHP) schemes can also be developed. CHP is one of the most efficient systems in the current time especially when installed to hospitals, leisure centers, hotels and general buildings that operate 24 hours with high heating demands. The system has plenty of benefits such as the following:

• Cost Saving – CHP’s high efficiency leads to a reduction in the use of the primary energy. The saving from CHP’s systems range between 15 – 50 %, with comparison to conventional boilers and cost of national grid electricity.
• Lower Emissions – The system is running under a single process and produces heat and power with less fuel being burnt, therefore reducing the carbon dioxide emissions.
• High Security & Power Quality – CHP systems can be designed to operate continuously and provide the essential loads required by the building. The system can also supply higher quality power than that of the national grid “this can be an important to computer centre etc”.

Investigation on the renewable energy site prepared is based on the Feasibilities Studies. The renewable energies considered are:

• 1. Solar
• 2. Wind
• 3. Geothermal
• 4. Fuel Cells

Energy Conservation Measures is a testing which is conducted in order to get an insight on how the building systems perform and estimate their efficiencies. This is carried out by professional engineers and relevant metering instrumentations.

Building Management System (BMS) can significantly improve management and energy performance of a building. The system can provide 10 – 20% energy savings rather than independently controlling each system. The energy consumption monitoring is important in providing the building operator in order to avoid problems that may occur. Therefore the energy meters connected to the BMS provide a historical record of energy performance of the building.
