Abstract
The idea of sustainability in the residential sector has been spreading with the objective of this sector to improve its environmental performance. The residential sector is a consumer of both electricity and thermal energy (cold and heat). The quantity of each type of energy demanded is influenced by the income of the consumer, the prices of the products that demand electricity, the quantity of people consuming these utilities, the loads inserted in the environment, among others. These demands can be met in a conventional way, consuming electricity directly from the grid, or in an unusual way, through the simultaneous production of two or more utilities (cogeneration), which can result in economic and environmental benefits for the sector. An optimization study is indicated whenever there is the possibility of producing two or more types of energy, in order to meet the energy demands with minimum cost, for example. The optimization depends on the energy demands of the building, electricity tariffs and other energy utilities, and legal regulations. The objective of this work was to obtain the energy demands (electricity, hot water, and refrigeration) for a residential building, for later application in an optimization of the energy supply. EnergyPlus software was used for calculations, a specific tool for thermoenergetic performance of buildings. The building has 20 floors with two apartments of 92 m² on each floor, located in the city of João Pessoa, latitude -7.11 ° and longitude -34.86 °. The final energy demands were 170 MWh / year of electricity, 83 MWh / year of hot water and 242 MWh / year of cooling.
