Cross-laminated timber (CLT) panels consist of a massive timber construction technology, which has been standing out in several countries, and has a promising future in Brazil, due to the national forest potential. The aim of this study was to investigate the thermo-energetic performance of CLT panels, made of eucalyptus heartwood, for vertical closures of different dwelling types, considering the climatic conditions of three cities in Mato Grosso state: Cuiabá, Rondonópolis and Sinop. For this purpose, the simulation method of the Brazilian Technical Regulation of Quality for the Energy Efficiency Level of Residential Buildings (RTQ-R) was applied. The results showed that CLT façades can provide satisfactory thermo-energetic performance under the climatic conditions of Mato Grosso. With CLT panels, it is possible to obtain residential buildings with energy efficiency levels that are similar – and even better – than those obtained with standard brick masonry; it is essential, however, that the envelope has low solar absorptance. In this sense, it is necessary revisions in the Brazilian standards that restrict the advance of lightweight innovative construction systems, such as CLT, in the country.
