Enhancing energy efficiency through passive design: a case study of halls of residence in Covenant University, Ogun State

Nigeria faces several energy challenges and currently does not generate adequate energy to meet the needs of the people. Plans and efforts have been made to generate more energy across the country, it is very important to explore affordable and natural ways to achieve energy efficiency and reduce excessive energy use in buildings. This objective of this paper is to investigate passive design strategies and the impact of passive systems such as natural ventilation and natural lighting to improve energy efficiency. This study also examines the current passive design strategies implemented in the halls of residence in Covenant University halls of residence from the building user’s perspective to identify the comfort levels provided by the passive systems implemented in the building.
