Résumé

The energy consumption of residential and commercial buildings, according to DGEG, in 2011 reaching about 28% of total final energy consumption in Portugal, thus contributing strongly to the increase of greenhouse effect gases in the atmosphere. In order to minimize the electric energy consumption and reduce the ecological footprint of buildings, there is need to use new solutions for air conditioning systems.
This article intends to analyze the comparative annual energy consumption between three alternative systems of climatization for a residential building to be rehabilitated, including a solar thermal system for the production of domestic hot water.

The selection of the air conditioning system with better efficiency was carried out through comparative energy simulations. The energy study considered passive measures to improve the energy performance of the building, taking into account the physical characteristics of the building and its application feasibility. In addition, an economic analysis of the air conditioning systems under study was carried out, allowing to designate which of these would have the lowest pay-back period.
