Summary:Energy performance and thermal comfort through EnergyPlus®, for a prototype of a single-family residence located in Foz do Iguaçu,climate zone 3A-Brazil. Using the estimated thermal sensation inside the house, natural ventilation was analyzed, where a system was compared considering the air infiltrations of the construction model with another of programmed selective ventilation; and two heating,ventilation, and air conditioning (HVAC) systems were proposed, being a Split system and a variable refrigerant gas flow (VRF) system.The results showed that, although the cases of natural ventilation influenced internal temperature and humidity, thermal comfort in the region is not feasible without the use of artificial mechanisms. The VRF system showed annual energy saving to the air conditioning of 14.76% and saving in the total annual energy consumption of 10.11% about the Split system, in addition to more economic profitability.
