Abstract: This paper evaluates the effects of natural ventilation on thermal comfort and risk of
overheating in low‐income tropical housing in Uganda. Dynamic simulations are conducted in
EnergyPlus to assess various strategies including single sided and cross ventilation, roof vents and
night ventilation in case study dwellings. The Chartered Institution of Building Services Engineers
Technical Memoranda 52 (CIBSE TM52) is used to assess thermal comfort conditions within the case
study dwellings. The results indicate that natural ventilation strategies marginally reduce the risk of
overheating. Overall, compared to other strategies, such as roof insulation, natural ventilation is less
effective in terms of improving indoor comfort conditions. This paper is a part of a series of
publications on the effects of climate change on thermal comfort in low‐income tropical housing.
