Anteprojeto de habitação popular bioclimática para a cidade de Maceió-AL, com vista à obtenção de título de edifício de energia zero

Abstract

This work presents architectural proposals at the level of a bioclimatic popular housing project, for the city of Maceió-AL, in order to obtain the title of zero energy building. The proposals were made for a hypothetical land and its implantation in the land was defined in relation to the solar orientation of the main facade: North or South. The objective of the work was the application of energy efficiency measures and bioclimatic architecture in the "North" and "South" proposals to reach ENCE Class A and the introduction of photovoltaic systems that supply 100% of the annual electricity demand. The method used to estimate annual energy consumption was ENCE's new classification proposal, the Normative Instruction for the Energy Efficiency Classification of Residential Buildings (INI-R). The simplified method was chosen, where two individual systems are evaluated: envelope and water heating. The results showed that the two proposals reached ENCE's class A of energy efficiency, presenting a percentage of consumption reduction of 37% in relation to the building in the reference condition. The estimated energy consumption calculated was used for simplified sizing of the photovoltaic local generation system. The dimensioned system will use 8 modules and will produce 3485 kWh/year, generating surpluses that return to the public grid. Finally, after the increase in local photovoltaic generation in the proposals, they receive an A+ energy efficiency rating at ENCE and are configured as a positive energy building (EPP).
