Abstract: This paper presents the first step of new labelling system for windows in Brazil. Multivariate regression equations were generated to predict energy consumption for heating, cooling and lighting of a building prototype. In this task, 28 different types of glass were selected to perform 336 simulation runs for three Brazilian cities. The equations resulted in good R², especially in the prediction of energy consumption from cooling, with values from 0.981 to 0.989 and independent variables SHGC, U-value and Tvis. Initial results show that benefits of high selective glazing systems can be evidenced for this type of methodology, helping the design team to select most suitable type of glass for each project. The next step of the research is to include window frames properties in the analysis and expand the sample of glass to cover a full range of possibilities in the Brazilian residential market sector.
