Study of Energy Efficient Building Design Techniques: Covenant University Health Centre

Energy efficiency, which is a key factor of sustainable building design is very beneficial to building occupants. This has made the focus on sustainability in the design, to be highly desirable. Studies show that two third of the energy used in existing residential buildings in Nigeria is generated via electricity, however; due to epileptic power supply, high cost of energy and high carbon emission, there is a need to minimize energy demand in the facility. This research evaluated sustainable design strategies and their effects on energy efficiency in warm humid climate of Nigeria. The climate, building envelope, heating, ventilation and air conditioning and lighting systems constitute are the main factors responsible for energy intake of a building. The research was based on case study of Covenant University Health Centre and data was collected through visual survey. The case study revealed that the building, at the time of construction did not consider sustainable design strategies in terms of materials of the building envelope, wall and window shading as well as natural means of cooling. Only lighting was considered.
