AN-92-15-4 -- Metered End-Use Data and Energy Conservation in a Department Store in Cairo, Egypt PDF

Measured energy-use data for commercial buildings in Egypt are scare. Summarises an effort to measure electricity consumption by end use in a government-owned chain department store in Egypt. Innovative techniques enabled us to effectively monitor the building with limited measuring equipment and little prior knowledge of the building's systems. The monitored data are used to estimate electricity conservation potential in the building. The major end uses in this building are lighting, ventilation, and air conditioning. The building peak use is about 60 W/m2 of power for lighting and 63 W/m2 for ventilation and air conditioning. It is possible to save 50% of the electricity use through improvements in the efficiency of the lighting and air conditioning systems.
