| description |
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. |

La vivienda de interés social es un segmento de la construcción que se encuentra regido principalmente por interés económico, tratando de solventar una problemática social. En años recientes se ha vertido un auténtico interés en este tipo de vivienda por responder a su adaptación climática en aras de responder a la función primigenia del hábitat: generar un refugio del exterior. Sin embargo, pareciera que los estudios realizados hacia la reconversión de la vivienda más adecuada al ambiente contraponen los intereses económicos y, por ende, se descartan de manera automática. Con esta investigación se pretende demostrar la posibilidad de aplicar adecuaciones climáticas pasivas a viviendas construidas sin socavar la economía familiar, mediante un análisis de costo-beneficio aplicando la metodología de análisis de costo de ciclo de vida. El estudio se realizó mediante simulaciones de escenarios, implementando mejoras a una vivienda tipo de 50.95 m2. Los escenarios simulados fueron el modelo base (MB), implementación de protección solar, aislamiento en ventanas, aislamiento en cubierta, aislamiento en muros y todas las estrategias previas. El análisis de costo-bene cio se realizó mediante una proyección numérica a 30 años con una tasa de inflación para la energía eléctrica del 5%, de interés nominal del 4.22% y de inflación de 4.03%. Los resultados mostraron que los modelos con mayor eficiencia fueron todas las estrategias (98.5%) y aislamiento en muros (94.6%). En términos económicos, el mayor ahorro neto fue el aislamiento en muros por encima de todas las estrategias, con un ahorro de $196,216.99 con un tiempo de retorno de siete años.
