This paper reflects and focuses on Energy Efficiency (EE) for commercial institutions and public utilities. The EE of a building is the extent to which the energy consumption per square meter of floor area of the building (kWh/m2/annum) measures up to established energy consumption benchmarks for that particular type of building under defined climatic conditions. Building energy consumptions benchmarks are representive value for common building types against which a building actual performance can be compared. Benchmarks are applied mainly to heating, cooling, air conditioning, ventilation, lighting, fans, pumps and controls, office or other equipment and electricity consumption for external lighting.
In Egypt, there are important opportunities to improve EE in government facilities, operations, and public infrastructure and services. Benefits include lower government energy bills, reduced greenhouse gas emissions, less demand on electric utility systems, and reduced fuel. In the paper five case studies are carried out. The steps are preparing the auditing, monitoring the electrical parameters, analyzing the measurement result and inspection data and option solution to provide
EE improvement.
