In the network are two universities: Faculty of Architectures and Urbanism of Sao Paulo University (FAU-USP) and Federal University of Pernambuco, Recife.

The University of Sao Paulo undertook a study on the ambient comfort conditions and energetic efficiency in social flats [1]. After the survey, cooperation was established with the Company of Housing of Sao Paulo Municipality — COHAB, having been simulated, by request of COHAB, the replacement of fibro concrete tile by clay tile, wall of concrete blocks by brick walls, application of thermal insulation on the roofs and the increase of solar gain areas (window area). The research team

simulated also the solar protection by adopting solar shading devices on the transparent areas. The increase of window areas was studied in terms of thermal-energetic aspects, also in terms of day lighting [2].

In Brazil, the electrical consumption reduction in social housing can be achieved by the reduction of energy consumption for bathing hot water, actually is around 30% of the Brazilian mean consumption. With the adaptation of solar collectors on the roofs is expected a reduction of 50% in this final use, which corresponds a 15% of final reduction in the electrical energy bill of each habitation.

The University of Pernambuco identified some buildings incorporating bioclimatic concepts:

Ministerio da Educa? ao e Cultura (Rio de Janeiro), Santo Antonio (Recife) Building, Superintendencia do Desenvolvimento do Nordeste, Centro de Tecnologia da Rede Sarah (Salvador e Fortaleza) e o Nhcleo de Pesquisa Multidisciplinar da UFAL [1]. Since 2006 that have been analyzing the bioclimatic design contribution and correlating urban planning and urban climate, Fig.6..
