Using local materials and inherited construction techniques, societies have ensured that buildings provide protection and comfort. Alternatively, so-called "vernacular" architecture -- buildings designed in direct response to the local climate, materials, geology and traditions -- is often energy-efficient and protective of surrounding eco-systems. With this in mind, architects and urban planners are increasingly looking to the past, according to Sandra Piesik, editor of the new book "Habitat: Vernacular Architecture for a Changing Planet." Even if local materials are not suitable, local traditions may be, as architect Driss Kettani demonstrated with the Technology School of Guelmim in Morocco. And the arrangement of the school buildings maximizes the flow of air through the complex, creating a natural cooling system.
