Enhancement of human and environmental wellbeing due to gas emissions has prioritised national development towards decreasing energy consumption in buildings. Unfortunately, building design and methods in developing nations are not sufficient to achieve reduced no energy consumption. Therefore, this study aimed to assess strategies for energy-efficient buildings in the institution. To know the different design strategies available to build and maintain an energy-efficient building in an institution; literature analysis, structured questionnaire, observation and simulation analysis was performed using Insight 360 software to analyse the building within the Bells University of Technology, Ota. The questionnaire showed that different energy efficiency indicators and strategies analysed from the literature were adequately utilized (41.14%) in the institution. Also, built professionals (students and staff in construction, architecture and designing section) have a background to moderate knowledge of energy efficiency. The simulation result showed a reduction in energy consumption of the building in response to building orientation, window shade, wall-towall ratio, wall construction and roof construction. This shows a great ability to reduce energy consumption and improve human health and well-being. The study concludes and recommends that one of the factors to put into consideration when designing is the nature of the building envelope because it determines the energy required to heat and cool. The government should increase awareness on Energy efficient buildings and appropriate laws should guide the implementation of Energy efficiency in building design policy. |
