Impact of glazing to wall ratio in various climatic regions: A case study

Abstract It is architecturally accepted that glazing system is considered as the most fragile part of buildings in terms of energy indoor performance. It is the only part of the building which has direct solar gain due to the transparent materials. Consequently, this part of building envelope should reap high consideration by architects and engineers, particularly in regions where solar radiation is high. The research aims to investigate the influence of glazing to wall ratio in different microclimate regions in Saudi Arabia which has been introduced by the author hot dry, hot humid and moderate climates. The research has studied the most possible glazing ration in the region based on previous work 5%, 10%, 20%, 30% and 40% out of the external wall. The paper used computer modelling TAS EDSL which has been validated using field monitoring study. Moreover, globe thermometer be used in order to investigate the impact of student’s position with respect to glazing system. Finally, questionnaire will be utilised to obtain actual thermal comfort from students in the selected regions with maintaining the same PSBD. The study reveals that south and east directions are the worst in terms of gaining the maximum amount of heat in all the locations. The research suggest that glazing to wall ratio is recommended to be 10% in both climate conditions hot and dry and hot and humid.
