dc.description.abstract | The rate of energy use around the world in recent years has been alarming. In Africa, and Tanzania in particular, the energy demand for office building is increasing annually as a result of urbanisation, population growth and economic growth. Reducing office buildings' ever-escalating energy use is a critical objective requiring scholarly attention. To contribute to achieving that objective, this study compared the energy performance of 2 green and 15 non-green office buildings in Dar es Salaam, Tanzania. The buildings were sampled purposively. The build-ings' consumption patterns were studied by examining their electricity bills over a five-year period (2015-2019). The buildings' energy consumption data and elements of their designs were analysed using multiple regression models. The study examined four building sets (green buildings, non-green buildings with maximal glazing, non-green buildings with minimal glazing and traditional office buildings). The results indicate that the traditional office buildings, which contained the most climate-responsive design elements of the building types examined, consumed less energy than green-certified office buildings. The modern office buildings with minimal and maximal glass façades consumed the most energy. The buildings with single-split HVAC systems consumed less energy than those with multi/central systems. The study concluded that building classifications and HVAC type are the most significant predictors of energy use, followed by window-to-wall ratio. As East Africa urbanises rapidly, these findings will provide architects, engineers, property managers and policymakers with research-based, real-life data that are specific to their context. Those data can help enhance the performance of green and non-green buildings during their design and operation phases. The study recommends adopting a design strategy that considers both climatic and technical factors in order to optimise building design decisions to lower buildings' energy use. | - |
