Abstract
As consequence of effects of climate change in the foreseeable increase of temperatures, the search for solutions which improve the thermal performance for the buildings turns on a key point. It is especially important in the case on summer conditions and, in addition, in urban spaces due to the dramatic effect of the heat island. From this perspective, green envelopes are an effective alternative which satisfied the double function, namely, improve the urban microclimate and the thermal behavior of the buildings in summer conditions. In urban spaces, façades have more incidence than roofs given the common characteristics of the constructions. From this point of view, the optimization of the thermal solutions for this constructive system should be taken into account as a measurement to improve the thermal performance in a global way. Under these circumstances, green systems satisfy the fact to reduce the temperature of the surfaces by shadowing them as well as improving the thermal insulation by the substrate. Indeed, it was demonstrated that the green systems with substrate are more thermal effective than the solutions without it. However, the water content in the substrate substantially modify the global behaviour of the envelope and their effect should be pointed out. In this research, several types of spreadable substrates are analyzed and their thermal performance is defined by an experimental methods. Conclusions arise about the influence of the water content in such thermal characteristics.
