In summary, low thermal conductivity of the roof along with high thermal mass proved to be
the key factors in reducing the risk of thermal discomfort. The priority, however, should be given
to the roof as it is critical in achieving acceptable thermal performance in tropical climates. This
research concentrated on the thermal performance of common construction methods and materials in Uganda. Further research is required to evaluate the effects of ceilings and insulation
levels as well as emissivity and solar absorptance rates of the roofs on thermal comfort conditions.
A sensitivity analysis is also required to evaluate the effects of various parameters such as occupancy patterns/behaviours, shadings, ventilation rates and strategies and thermal condustivity
values on the thermal performance/comfort in low-income houses in Uganda.
