The results of the survey show that several factors affect the energy performance in this building. It revealed that the building has been poorly designed from the point of view of thermal performance. Therefore, the building energy consumption needs to be monitored and maintained through energy auditing program. To determine the energy profile, the power consumption was calculated;the cooling load was estimated and analyzed to know the actual capacity required. The level of comfort in the building has been evaluated. Against the installed air conditioning capacity of 200-ton refrigeration, the cooling load calculations showed that the maximum cooling load needed, which is in August is only 83.22-ton refrigeration. In addition, illumination levels were measured and compared to the standard levels. Based on obtained results, two solutions were proposed: to install a building management system with approximate cost of 337,904 SR and to replace the existing chiller. Finally, the payback period for the proposed system has been estimated and found to be about 5.4 years.展开更多
