Reflective Glass

The construction market offers a variety of materials always with innovative alternatives for specific cases. Among these materials is glass one of the main building components as it contributes to natural lighting. However if the choice of glass is not correct due to the transmission of radiation and high heat absorption it is necessary to install air conditioning units which in turn consume a large amount of electricity which is currently very expensive due to the water crisis the country is experiencing. In this context the main objective of this work is to analyse the thermal performance of float glass cool lite line S - 436ST-Green and cool lite knt line K - 455 - Green supplied by Cebrace and widely used on the façades of buildings in Brazil. To do this measurements were taken on prototypes with the three types of glass comparing the temperature outside the glass and inside the prototype.
