Abstract
Due to the expectation of climate change and increasing global temperature, new building rates will face challenges. Nearly 40% of world-wide carbon emissions can be linked to building's energy consumption. Therefore, it is significant to understand how a building's energy consumption will behave under future climate change in order to reduce carbon emissions. The residential sector's demand for energy in the KSA is massive at 50%. Based on recent government initiatives of KSA, mandatory new residential buildings must meet stringent energy codes. This study investigates the effects of applying the new Saudi residential building energy codes for a detached single-family house (villa) located in Jeddah, KSA. This study aims to see how the code might perform under current and future climate change scenarios. Although the current code already shows a significant improvement in combating future climate change, a total reduction of 38% in the annual cooling demands of existing villas in Jeddah after applying the new standards will be illustrated. However, increases in cooling energy demand due to climate change still exist. Applying more passives strategies that are not included in the code would assist the researcher in knowing if there are other means to achieve significant decreases in cooling demand.
