Evaluating the Impact of Adaptive Building Form and Orientation on Indoor Air Quality in Selected Four-Star Hotels in Nigeria

The study examines the impact of adaptive building design on indoor air quality (IAQ) in four-star hotels in Nigeria. The research, which used a cross-sectional survey with 380 respondents across four hotels in Lagos State, found that adaptive features like natural ventilation, optimal building orientation, and energy-efficient materials significantly improve IAQ, reduce energy consumption, and enhance guest comfort. Hotels with adaptive designs showed higher IAQ ratings, with natural ventilation reducing reliance on mechanical systems and contributing to energy savings. Building orientation, particularly in relation to sunlight and prevailing winds, significantly impacts temperature regulation and overall indoor comfort. The study emphasizes the need for hotel staff training on the proper use and maintenance of adaptive systems. The findings provide valuable insights for architects, hotel developers, and operators seeking to create healthier, more energy-efficient environments for guests in Nigeria's tropical climate.
