Description

Insecticide treated bed nets (ITNs) is still the main malaria control measure for the sub-Saharan region in Africa. A number of research in the past further showed the effectiveness of closed eaves, screened windows and doors in preventing mosquito intrusions into indoor spaces. However, the hot and humid climate makes the occupant difficult to remain under the bed net, mainly due to the restricted ventilation causing further discomfort, and increasing the risk of malaria infection while sleeping outside ITNs. Increasing the indoor comfort during the sleeping hours remains as a challenge.
The current work presents the selected architectural parameters investigated with the aim to increase indoor comfort of typical rural houses, and their impacts on the indoor temperature and CO2 concentration. Different roof types, sizes of screened windows and a solar chimney were investigated in silico, and the results show that, increasing the size of screened windows was the most effective in reducing the temperature while minimising indoor CO2 concentration.
