Remodelling façade design for improving daylighting and the thermal environment in Abuja's low-income housing

This paper evaluates the performance of four of Abuja's common housing types and examines the impact of changing their fenestration design on occupants' comfort, using validated simulation. Assessing the performance of the buildings in their existing state revealed clear overheating problems and excessive natural lighting. However, the investigation indicated a 4-6% reduction in the frequency of thermal discomfort and a 4-29% reduction in visual discomfort by adjusting the orientation of the facades. Integrating external shading components can also reduce thermal and visual discomfort by up to 4% and 29%, respectively.
