A survey was done in order to identify bioclimatic design and passive solar strategies for cooling and correspondent benefices. Actually exists in Mexico programs and projects for construction of social

houses in large scale and based on that survey were selected some of the approaches used for the different types of climate, air conditioning solar systems, solar hot water and water reuse. In Ciudad Juarez were used as passive solar strategies the ground cooling ventilation and shading devices. In Mexico D. C. particular attention was given to the house implementation and windows orientation in order to minimize the solar exposure and at same time the use of effective shading devices. For hot dry climates (Santa Isabel, Chih.) is recommended the use of massive materials in order to increase the thermal inertia and established of interior microclimates. However, in Mexicali, the strategy consists on the application of thermal insulation and the electrical energy production [1].

A study on the CO2 emissions was done for the period 2001-2006 and one prevision for the period comprise 2007-2012. The construction of 6 millions of social houses until 2012, approximately 23% of the number actually existent, will contribute for an increase on 16,770 GWh of the electrical energy consumption. Nowadays is been elaborated the guidelines for the social houses in Mexico and the first text for sustainable houses Certification [2].
