RETROFIT ENERGÉTICO EM UM EDIFÍCIO HISTÓRICO EM PELOTAS, RS, SEGUNDO O RTQ-C E A ENERPHIT

The city of Pelotas has 1,700 buildings inventoried by the municipality, having in its downtow a great collection of historical buildings. In this sense, it is very important to create mechanisms of incentive to avoid degradation by abandonment. One of these mechanisms is the energy retrofit because, in addition to revitalizing the building, it also improves the thermal comfort of its users. This study had as its object the retrofit in a commercial historical building of the century. XIX of Pelotas. To compare the energy performance of the building before and after the retrofit, the RTQ-C (Technical requirements of the energy efficiency level of commercial, services and public buildings) and the German EnerPHit Standard certification were adopted as parameters. The computational simulations were carried out with EnergyPlus software, observing possible energy optimization measures to preserve the facade and the volume of the building. Then, the cost of these modifications and the payback of the investment were evaluated. Finally, it was verified that it is possible to carry out the energy retrofit in a historical building without changing the architectural elements if its facade obtained a high level of thermal comfort and energy efficiency of the building.
