SHARIF INTERNATIONAL RENEWABLE ENERGY | ENERGY CONSERVATION | AVIATION October 26, 2017 ELECTRICAL SAFETY ENERGY AUDIT UN-WFP COUNTRY OFFICE BUILDING ACTIVITY REPORT 1) INTRODUCTION i) Background The basic purpose of electrical safety energy audit at UN-WFP Country Office building is to inspect, test, analyze and mitigate the risks associated with electrical systems and equipment with the purpose of maintaining safe operations and reducing system interactions and equipment breakdown.When the object of study is an occupied building then reducing energy consumption while maintaining or improving human comfort, health and safety are of primary concern. Beyond simply identifying the sources of energy use, an energy audit seeks to prioritize the energy uses according to the greatest to least cost effective opportunities for energy savings. Scope of the Evaluation 1 To achieve properly engineered electrical distribution system by evaluating the electrical load and operating load requirements for UNWFP building. The purpose of this assessment is to review the design drawings and physical power distribution network including power regulator/ control system to determine the rating of electrical wiring/ transmission systems. The building is already equipped with electrical infrastructure but may require improvements works.
