ABSTRACT
Tourism has become one of the most important sources for variation ofincome. Saudi Arabia is seeking to establish a sustainable touristicsector through new projects in the Northwest of the Kingdom acrossthe Red Sea shores. This study focuses on the development of currenttouristic facilities to keep abreast with touristic sustainability plans.Buildings’ energy consumption increased from 33.7% to 41.1%between the years 1980 and 2010 in the United States (Cao, Dai, &Liu, 2016), and in 2021, buildings accounted for 37% of energyconsumption (Hamilton, Kennard, & Others, 2022). Hence, retrofittingof building’s envelope contributes to the reduction of energyconsumption and mitigation of carbon emissions. The objective of thisstudy is to improve the thermal efficiency of buildings by treatingthe façades of residential units. This study has been applied on Jeddah city which representshot humid climate. The residential units were chosen in (Boho) complex and the(DesignBuilder) program was used to apply a number of architectural solutions forredesigning the building envelope. These solutions included treatments of windows, walls and roofs to improve the heat transfer coefficient, and orientation was examined. The studyconcludes that applying these strategies leads to reduction of energy consumption by(57.1%), hence improving environmental performance.
