| Resumo: | Low-income housing is a segment of construction that is governed mainly by economic interests trying to solve a social problem. In recent years there has been a real interest in this type of housing to respond to its climatic adaptation in order to respond to the original function of the habitat: to generate a refuge from the outside. However, it seems that the studies carried out toward the conversion of the most suitable housing to the environment contradict economic interests and, therefore, are automatically discarded. This research aims to demonstrate the possibility of applying passive climatic adaptations to build homes without undermining the family economy, through a cost-benefit analysis applying the life cycle cost analysis methodology. The study was carried out through simulations of scenarios implementing improvements to a 50.95 m2 typical house. The simulated scenarios were the base model (MB), implementation of solar protection, window insulation, roof insulation, wall insulation, and all previous strategies. The cost-benefit analysis was carried out through a 30-year numerical projection with an inflation rate for electric power of 5%, a nominal interest rate of 4.22%, and an inflation rate of 4.03%. The results showed that the models with the highest efficiency were all strategies (98.5%) and insulation in walls (94.6%). In economic terms, the greatest net saving was the insulation in walls above all the strategies, with a saving of $196,216.99 pesos with a payback time of seven years. |
