This paper aims to compare the thermal performance results of the envelope of a residential building, using the RTQ-R and the NBR 15575-1 simulation methods. In order to obtain different levels of performance, a random experiment with the kLatin Hypercube Sampling method was performed. The variable parameters were selected and 500 random combinations were generated. The climate of Florianópolis-SC was considered, and the EnergyPlus computer programme was used. The results showed that, depending on the scenario analysed, the methods may give similar results. Most cases had different results over the winter, where 134 cases resulted in level A or B with RTQ-R, and Minimal or no-compliance with the NBR 15575-1. Over the summer, 66 cases resulted in level E with RTQ-R and Intermediate level with NBR 15575-1. Although the sensitivity analysis indicated similarity between the simulation methods, the RTQ-R is a more complete and comprehensive evaluation method. However, more attention should be given to the methods' classification process, which may be the cause of some of the differences.
