Building orientation is the positioning of a building in relation to seasonal variation in the sun path as well as prevailing wind pattern. It is no doubt a significant design consideration. Building orientation is also the practice of tilting a building towards maximizing certain aspects of its surroundings, such as a street appeal, scenic view and drainage advantage among others. The impact of orientation on a building ranges from thermal comfort to lighting, ventilation, energy consumption and economy of building. Sustainable building design can be used to save building operating energy and to correctly predict the amount of energy to be consumed. The research aims at assessing the effect of building orientation on thermal comfort, daylighting, ventilation and economy of building on buildings in Ikotun area of Lagos Nigeria. The research sourced for data via the use of literature reviews, case studies of various buildings in Ikotun and the use of questionnaires for Ikotun residents to assess their level of comfort which in turn is used to evaluate the effect of building orientation. Questionnaire was also sent to the built environment professionals to get their professional input on the topic. The research findings show that longitudinally true south orientations, longitudinally north-east and latitudinal north-east maximize building performance to occupants.
