This paper describes the development of the Residential Energy Model (REEM) for Saudi Arabia using an engineering bottom-up approach. The model can assess energy demand for the current residential building stock and the impact of energy efficiency and demand-side management programs. It accounts for the makeup and features of the Kingdom’s existing housing stock using 54 prototypes of residential buildings defined by three building types, three vintages, and six locations representing different climatic zones.
