4. Conclusions
This paper investigated the effects of natural ventilation strategies on thermal comfort in low‐
income housing in Uganda. According to the results of this study, although natural ventilation
strategies improved the conditions, such improvements were enough to pass the assessment criteria set
by CIBSE TM52 and BS EN 15251 standards. Natural ventilation should therefore be considered along
with other strategies, such as solar shading, in order to further improve the conditions. In contrast,
using appropriate construction methods/materials such as brick walls and insulated roof, significantly
improved the comfort conditions. Yet, due to the extremely bad comfort conditions in houses covered
with iron sheet, ventilation strategies seemed to be more effective in improving the conditions
compared to insulated roofs. The best conditions were achieved when cross ventilation and night
ventilation were considered together. More investigation is required to assess the effects of natural
ventilation in conjunction with solar shading and refurbishment strategies in low‐income housing.
