Abstract
This paper aims to analyse and evaluate the relevance of the established limits, as well as to propose a compatibility methodology between the methods of evaluation of thermal performance adopted by NBR 15575. The studies were conducted for bioclimatic zone 2, taking a one-storey, social housing building as caso base. The studies were performed through a computer simulation of 300 randomly defined configurations using the Latin Hypercube method; the building was modelled and configured by the 3.0.0.105 Design Builder program version and then simulated according to NBR 15575's criteria for a typical summer and a typical winter day, as well for the entire year through a reference climate file. The results show that there is no compatibility between the simplified method and the simulation method in the typical days, since in the latter almost all configurations are approved. The annual simulation method by degree-hours proved to be more coherent with the requirements of the simplified method. By establishing discomfort degree-hours (DDH) criteria, it was possible to establish the compatibility between the methods, so that, in order to be approved by simulation, the building must present at least the performance specified by the simplified method. The limit values of the simplified method proved to be coherent, requiring only the indication of an increase in the minimum value of the thermal capacity.
