The evaluation of the buildings, with basic shade and solar angle study in Heliodon. 4. The analysis of facades and vegetation of the buildings, with surface temperature, existing vegetation, wind speeds and the flow direction. Conclusions: The study demonstrates the critical months from April to October, the need of solar protection in summertime on all the facades through the entire day. The best orientation for a building is North-South. The most critical facades are West, Northwest and Southwest. Separation between buildings allowed the wind to flow without obstructions and remained directed to the Southeast the whole day at a light air speed during the morning, and during the afternoon, its speed increased to a soft breeze.
