Description
At present, most developed countries attempt to highly diminish the energy consumption of buildings towards nearly zero-energy performances. This study assesses passive design strategies by means of multi-objective optimizations with genetic algorithms, aiming to minimize the heating and cooling demand of typical single-family dwellings in Chile. The results show that the thermal transmittance and airtightness of the whole building envelope should be highly improved from the current limiting values in all assessed locations. Complementarily, strategies for managing overheating would be crucial for avoiding to shift the heating demand into cooling. With this regard, the use of thermal mass, natural ventilation and shading devices in the east and west façades would be highly determining for achieving a balance between the two conflicting objectives throughout climatic zones in Chile.
