In the high altitude zones of the Himalayas many houses were analysed and improvement options discussed with house-owners. Over 50 different types of improvements were developed and applied through local entrepreneurs.
Small house improvements such as lightweight insulated roofing and solar windows were also applied in many school buildings.
