Integrated design is a strategy to develop sustainable architecture projects incorporating multidisciplinary work and environmental performance assessments, which has provided significant advancement to public buildings in developed countries. This paper presents a review of some aspects of integrated design for the planning and construction of energy efficient housing in the south of Chile, as part of the reconstruction process following the earthquake on 27th February 2010. Firstly, a synthesis is made of the characteristics, implicit conditions, participants, steps, resources and expected results of an integrated design approach according to existing references. This is then contrasted with normal housing design practice in Chile according to current building regulations and interviews with professionals in the field. The design processes of experimental houses and housing projects that place specific focus on energy performance are then analysed, with follow-ups and interviews to review significant aspects. After examining those experiences, the authors identify some particular features and resources of integrated design that promote environmental improvements.
