Use of renewable ressources - low tech
natural cross ventilation, evapoartive cooling, use of high thermal mass
Renewable, recycled, recyclable and innovative materials

The buildings are constructed using the earth-block method. Roof constructions, doors, windows and other details are built of bamboo. Oil- or coconut-palm leaves are used to make roof coverings. The construction uses as little wood as possible.

Social and ethical responsibility

Local construction methods were developed and improved upon in ways tailored to local craftsmens' abilities; thus supporting the local "construction culture" and reinforcing village identity. The local craftsman were trained on the building sites while erecting prototypes for the new building method around the region. The eleven buildings serve as preschools, which can also be used as community and adult-education centres.

Ressource efficiency and environmental impact

The used construction materials are obtained from nature, and then return to nature after the house's lifespan has ended. In order to combat deforestation, the construction system is designed to use as little wood as possible. Instead, the buildings are constructed using the earth-block method, which can also be found in the region. Roof constructions, doors, windows and other details are built of bamboo, harvested by the local people.

Economic lifecycle perfomance

By extending the lifespan of the buildings with new construction methods, people do not need to build a new house every five to eight years. Generally the costs of the construction are kept very low by using as many local materials as possible.

Contextual performance and impact

The public learning centers were designed to inspire local residents to imitate the new style for their own homes.
