The cross-laminated timber (CLT) has been successfully applied in buildings around the world, and it is a promising technology in Brazil. The aim of this paper was to investigate the thermo energetic performance of CLT panels made of eucalyptus heartwood for use in vertical closures of multi-story dwellings under the climatic conditions of Brasilia and Santa Maria. The research was based on the simulation method of the Brazilian Technical Regulation of Quality for the Energy Efficiency Level of Residential Buildings (RTQ-R). The results, based on 12 simplified parametric simulations, proved that the innovative construction system have significant potential for thermo-energetic improvement in multi-story dwelling types under the climatic conditions analyzed. The simulated envelope combinations showed that it is important to associate 5-layered CLT panels with low solar absorptance in the envelope for better performance results (energy efficiency level A). It is concluded that the technology is adequate for the situations analyzed in Brazil, and that is necessary to review the Brazilian
