Abstract
The objective of this paper is to demonstrate the potential of energy consumption reduction in residential buildings located in southeast cities of Brazil through the application of passive design strategies. Taking into account a simple definition, the passive design strategies can be defined as a set of strategies that promotes energy consumption reduction by controlling heat flows through the elements of the building envelope. The study was developed through energy simulation employing the EnergyPlus software, which is specifically designed by the U.S. Department of Energy to model both energy consumption and water usage in buildings. The specification of climate conditions in the EnergyPlus software was stated by declaring a weather data file of Taubaté (SP) city. The energy consumption simulations demonstrate that the natural ventilation use, windows glazing systems replacement by models with improved thermal properties, and the painting of external walls with low solar spectrum absorptance paint are some of the passive design strategies that lead to significant energy consumption reduction. The mean results demonstrate that is possible to reduce the building energy consumption in the range of 24% to 33% considering one or two air conditioning appliances per apartment.
