Validation of thermal improvements in housing for the reconstruction process post-2010's earthquake. Dichato, Chile

Abstract:

The relevant participation of dwellings in the overall energy consumption in Chile, justifies the study of improvement opportunities, especially in reconstruction programs that are solving the housing deficit and the thermal retrofitting implemented after the earthquake on February 27th 2010. This article, which is part of the research project "Integrated Design for the Reconstruction of Energy Efficient Dwellings" (Conicyt-MEL 8110003) And expose a strategy of diagnosis and evaluation to the thermal improvement through outer envelops for low cost housing located in reconstruction areas. It develops an analysis and solution for the thermal envelop that can be applied in the earthquake's most affected regions in the central-south areas of Chile (Maule, Biobío and Araucanía). It presents a case study with quantitative methods for the technical and financial validation of a proposal for thermal improvement, and qualitative methods for the social validation of the involved actors. The results confirm a strategy that may contribute in the reduction of the consumption and developing attitudes able to direct towards the promotion of energy efficiency. The outcomes may be generalized and the experiences can apply to other regions, looking after their particular conditions.
