For Ns et al. (2001) the roof is more significant the constructive element in avcola installation, how much to the control of the radiation solar incident. The flow of heat through the coverings, together with the raised temperatures in the inferior face of the roofing tiles, is the root cause of the discomfort in the interior of the installations. The ventilation is necessary to eliminate the excess of humidity of the environment and the bed, proceeding from the set free water for the breath of the birds and the dejections, to allow the renewal of air and to eliminate odors (STOLEN; AZEVEDO; TINOCO, 2003), and that one of the alternatives to improve the thermal conditions and to promote the renewal of air, is the forced ventilation. When it does not have problems with the saturation of the air inside of the aviaries, can be used the system of evaporative cooling, consisting basically of the use of vaporizars, allowing that the saturated air of the environment does not enter in contact with the water in temperature lower, occurring then to the exchange of heat between air and the water. To reduce the temperature of the roofing tile and circunvizinhana in the hours of intense heat, aspersion can be used on covering. The avcola production, for its competitiveness, requires simple, projected constructions of form that allows the natural thermal conditioning, being used the artificial system of conditioning when if only not to glimpse another situation (ABREU; ABREU, 2002). To if planning an installation, that is, to promote the thermal conditioning of the same one it is necessary to know the characteristics of the natural way that constitute the local climate and to compare them with the conditions of physiological comfort of the birds for which if it projects the installation. Of the confrontation of the two situations the modifications are gotten that must be carried through in the natural climatic situation, the half ones are deduced to get them and are elaborated solutions constructive and energy techniques.
