One of the main measures of the Government to tackle the housing shortage was the creation of the Minha Casa Minha Vida ( MCMV ) , which aims to encourage the production of new housing units and the acquisition by different income groups. As some of the programs that preceded it , the MCMV has been marked by repetition of architectural and construction solutions that do not consider environmental or climatic factors . In the case of Housing Benjamin José Cardoso ( CHBJC ) in Viçosa-MG , we adopted a design -story house with two bedrooms , very similar to models that have been implemented in other regions of the country . In the face of climatic and environmental conditions of Viçosa-MG , located in bioclimatic zone 3 , are made necessary studies on the suitability of the model used , since the standard unit , performed in CHBJC , is now being replicated in other sets city . In view of this gap and regulatory provisions for environmental performance of residential buildings , this study aimed to examine the thermal and acoustic performance of building - type built in CHBJC and highlight aspects that influence the results of these analyzes . The methodological procedures comprised the determination of thermal properties ( NBR 15220:2003 ) and acoustic ( NBRS 10151:2000 , 10152:1987 and 12179:1992 ), exploratory interviews and on-site measurements of dry bulb temperature, relative humidity , temperature surface and sound pressure. For data analysis, we used the requirements and criteria set by the NBR 15575:2013. It was found that the units do not meet the minimum level of thermal performance analysis by simplified method, the method of in situ measurements, the units showed thermal performance above the minimum in summer, but in most cases , do not meet the level minimum performance in winter. Also found that the requirements set out in and critéiros NBR 15220 were not observed in the preparation of architectural design. As for the acoustic performance in 83 % of cases evaluated the requirement analysis , acoustic insulation of external seals , has been met. Although the analyzed units have not met all the requirements set by the standards, measures such as , for example, change the configuration of the windows and doors and the thermal mass of the walls, can improve the performance of the units of the set and other sets to be constructed in the region.
