Energy audit is used in this paper as an efficient method/tool to assess and study the energy profile of a large office building in Riyadh City. The various components of the building are analyzed, such as specifications of the walls, the roofs, the windows, the lighting fixtures, the office equipments, the chillers, HVAC, the additional air conditioning units known as split types and the other equipments in the building. It has been found that air conditioning system represents 50% of the total installed power. The energy audit study has helped to diagnose and then define certain solutions and modifications for increasing energy efficiency in the building. The potential energy saving and the pay-back period of the proposed modifications are also calculated and analyzed for different solutions. After the implementation of the proposed modifications, the pay-back period is estimated to be 29 months. Recommendations are suggested according to the optimum solution.
