EFFECT OF WINDOWS TO WALL ORIENTATION ON ENERGY EFFICIENCY IN INSTITUTIONAL BUILDINGS IN YOLA

Architectural Technology

Globally, a significant proportion of building energy is economically consumed for achieving the required thermal and optical comfort. The most important parameter affecting the thermal comfort and lighting energy is the window to wall ratio (WWR) of the building. It is important to keep in mind the "economic" factors, which can greatly impact the quality of a home's space and therefore the quality of life of the homeowner. Empirical studies show that WWR of 10% is recommended for hot and humid climate region. The aim of this study is to investigate the level of conformity of orientation of 40 selected buildings in MAU with regards to energy conservation. Case study research design was adopted to analyze the purposively selected buildings. The result revealed that North and South Cardinal have the highest mean value of WWR as compared with East and West and Sub-Cardinals. Therefore, it depicts that most of the studied buildings were oriented in tenant with the bioclimatic principles. It was recommended from the findings that incorporation of shading plants and vegetation among other passive measures that will help in minimizing energy consumption.
