Abstract:
This study investigates the potential savings in air conditioning energy and reductions in atmospheric pollutants in existing air conditioned mosques in Saudi Arabia. It aims to study in particular the improvements of passive cooling systems in existing mosques under three main headings of (1) the determination of (a) passive cooling systems' demand improvements and (b) the proposed measures for improvements, (2) their relative performances, and (3) their applications. Existing air conditioned mosques in city of Jeddah form the primary subject of this study, by surveying 48 existing air conditioned mosques' envelope, shading and night ventilation. Based on a better understanding of these passive cooling systems, combined with an analysis of the current economical, structural and constructional situations within existing air conditioned mosques, a coherent set of improvement measures have been proposed namely; (1) increase insulation values of mosques' fabric by adding various building and insulation materials for walls and roof, (2) increase shading by complete shading of windows and (3) increased night ventilation by ventilating the mosque for the whole night. A passive cooling evaluation method, appropriate to the measures defined, has been adapted to predict the potential savings in air conditioning energy, money and atmospheric pollutants. This manual method has been used to predict the various savings that can be achieved by applying these measures of improvements to nine case study mosques. A set of comprehensive tables showing the potential sayings in air conditioning energy, money and atmospheric pollutants emissions when applying these proposed measures for improving passive cooling systems in existing air conditioned mosques are produced. These tables can be used by the architects, by the mosques' management and by the Ministry of Awkaf (Endowment) who are responsible for mosque procurement and maintenance. Finally, the study has estimated the potential savings of these measures when applied to all existing air conditioned mosques in Jeddah and shown their relative contributions to reducing the national energy consumption and atmospheric pollutants emissions levels.
