(1) Porous wall materials (cladding) that are air permeable. (2) A concrete or timber floor that is elevated from the ground for sleeping areas. (3) A reinforced storage area that can be locked. (4) An outdoor cooking area with chimney connected to the main building and covered by a roof. (5) A water harvesting system that allows the collection of rain water through gutters and storage of water in a large plastic container. (6) An outdoor latrine.

Mean indoor temperature at 2130 h between August, 2015, and July, 2016, by house type
Reference house: a traditional house which was left unchanged and served as control. Modified house: major structural problems such as leaking roofs were repaired, windows screened, open eaves blocked with bricks and mortar, cement floors repaired or constructed, rain gutters and a tank for water storage added. Extra windows were installed in bedrooms with only one window to secure cross ventilation.
