The purpose of this work was to analyze the application of thermal efficiency principles for sealing masonry, made for the city of Itumbiara-GO; and the thermal performance evaluation of a building can be done both in the design phase and after construction. Using the regulations and specifications that guide the methods for investigating thermal performance and Energy efficiency for buildings, Brazilian standards are consulted that present specific guidelines for the various regions of the country and their respective Bioclimatic Zones, which stand out as NBR 15.220 (ABNT, 2005) and NBR 15.575 (ABNT, 2013); The Casa Azul Seal of Caixa Econômica Federal and Ordinance No. 18 of 2012 (RTQ-R: Technical Quality Regulation for the Level of Efficiency in Residential Buildings) are also attested. In the research we have the implementation of the EPS block (styrofoam) coated with concrete as an alternative to replacement for conventional bricks, with the application of specific thermal criteria; which demonstrated the implementation of new construction methods for the city of Itumbiara-GO, which is inserted in the Brazilian Bioclimatic Zone 6; aiming for better architectural designs for popular class buildings. The development of an alternative fence block for civil construction provides diversification in the use of materials encompassing the concept of sustainability in this field. Based on the results obtained, it is verified that the EPS block coated with concrete provides better thermal performance than ceramic blocks, evidenced by the calculated physical quantities that are standardized by current standards and that measure this concept: the thermal resistance is about 205% higher than the conventional ceramic block, the termal transmittance is 67.28% lower, the total thermal capacity is about 38% lower, the thermal delay is about 53% higher than the ceramic block, and finally, the solar factor is about 67 % lower than ceramic block. Where such comparative results prove the efficiency of the EPS block in relation to the ceramic block in terms of thermal performance.
