Abstract: This paper presents results of simulations and measurements concerning the thermal performance evaluation of a single-storied house prototype, built in Canoinhas (26°10'38"S), Santa Catarina, in Southern Brazil. This prototype was developed in order to attend a national program, which was created by the Federal Government in order to subsidize low-cost housing with a maximum subsidy of US$2,500 for the construction of 'do-it-yourself units. This study was developed in three stages: first, measurements of outdoor and indoor temperatures of the prototype were carried out during the summer (from December 2006 through February 2007); second, thermal simulations were made with IDA- Indoor and Climate Energy (Sweden) using original properties and characteristics of the monitored prototype; and the third stage consisted of thermal simulation with modified parameters (improvements) such as the composition of the wall panels, for three other climatic conditions, i.e. different geographical locations (Curitiba 25°25'40"S, Florianopolis 27°35'S and Porto Alegre 30° 01159"S), which belong to two different thermal zones in Southern Brazil. As a result, it was possible to evaluate the prototype's thermal performance and choose the best building configuration for each case, for winter and summer conditions.
