RESUMO

In Chile, 75% of the existing housing stock was built without energy-environmental considerations. These houses are becoming high energy consumers in the country. Nowadays, it exist different measures to improve the energy efficiency of existing dwellings, but these benchmarks consider only some performance that have implication on the energy demand. Normally, these performance are improving in an independently way, without considering the relationship between them and the effect that they imply when they are integrated. This research proposes to fill a gap in knowledge of how different performance-based behave integrally in the energy and environmental retrofitting of existing housing. Currently it is a lack of such knowledge, that under the performance based philosophy, generates various strategies for improve the final objective of performance-based in temperate climates: Thermal Comfort, Energy Efficiency for Heating and Indoor Air Quality. It is selected a case study located in the center-south of Chile. It is evaluated with a post-occupational diagnosis (monitoring, dynamics simulations and user perception surveys) to establish the performance criteria. Their relevance and interdependence are analyzed by a multifactorial study. We conclude that to achieve these goals is implicit to retrofit the existing housing under the integration of the following criteria: increased air tightness, decreased thermal transmittance value and delivery of the minimum ventilation rate; always in a comprehensive manner.
