|Abstract:||UAE has one of the highest electricity consumption per capita in the world. This reflects negatively on the CO2 emissions which is an increasing determination in the UAE. CO2 emissions must be reduced as part of the global effort to reduce the greenhouse gases and mitigate global warming effects. This study aims to reduce the electricity consumptions in the federal buildings in the UAE. This research used to find the best lighting and control technologies that can be used in Federal Buildings in UAE to reduce the total energy consumption by reducing lighting energy consumption as a direct energy and also the HVAC (cooling) energy which is the indirect energy that can be saved depending on saving in lighting energy. Three lighting technology proposals were compared to the existing lighting in MOPW-RAK building. The three proposed lighting technologies were compared to the existing lighting technology in three different areas: Meeting Room, Electromechanical Office, and Corridor. Also, lighting control technologies were also applied to the selected areas in the building and compared to the base case also. The building was simulated in two different simulation software’s: Dialux lighting simulation software and IES-VE building energy efficiency modeling software. Some calculations and comparisons between the results were done. From the results, analysis and comparisons we found that LED lights is the best because it has the highest amount of saving the lighting energy. CFL is the worst solution for our case because it uses magnetic ballast. This is the main reason of the high energy consumption in CFL. It was found that with the use of Occupancy sensors, energy savings were 10%, while for Daylight Sensor and Dimming Systems were 25%. The most expensive option is when using the full power lighting without control Systems. Using energy savings Lighting technologies not only affects lighting energy consumption, but are also affect HVAC energy savings because of the outcome heat from the Lighting technologies. Lighting Control Technology also have an effects on HVAC energy savings because of the relation between the HVAC and Lighting which was proved using IES-VE software which show that the Fraction between Lighting and HVAC is 0.33. In another word, each 1KWH of lighting energy equal 3 KWH of HVAC energy consumptions.|
