INTEGRATION OF PASSIVE COOLING DESIGN CONSIDERATION FOR FACULTY OF BASIC MEDICAL SCIENCES, FEDERAL UNIVERSITY, BIRNIN KEBBI, KEBBI STATE

Abstract

ABSTRACT A reoccurring discourse currently in the built environment of architectural practice and education is Passive Design as it has progressively become difficult to ignore the concerns by professionals in the built environment. This passive design approach is geared towards reducing potential negative impact of developments on the well-being of the environment and human health, through the use of an “eco-friendly” construction materials and principles. The Faculty of basic medical science building with integrated “eco-friendly” passive cooling design features will enhance the indoor air quality by eliminating heat gain within the building and replenishing the indoor environment with the most efficient and most comfortable temperatures for human activities. The aim of this study is to integrate passive cooling design considerations with the view to achieving good indoor air quality and environmental sustainability. The method of sampling employed for this research is the convenient purposive sampling. A purposeful survey was conducted on four (4) faculties of basic medical science buildings in tertiary institutions in Nigeria. A direct observation of passive cooling variables which include orientation, building envelope, thermal mass, shading and overhangs, openings, ventilation, and landscaping. The instruments used in collecting information for this research are questionnaires and observation schedule. The research findings revealed that passive design features for energy efficiency are green roof, soft landscape, roof vent, evaporative effect, and atrium for cooling the building. The research recommended that green building design should be made a criterion to be met by design proposals before approval for construction is given to ensure that new buildings are sustainable.
