Abstract
Purpose
This paper aims to review the application of integrated design strategies in several cases of housing in south-central Chile in search of ways to significantly reduce energy loss and demand.
Design/methodology/approach
First, seven main design features of energy-efficient buildings in developed countries were identified. Second, these features were reviewed in two professional case studies from architectural practices and two academic exercises on residential design in south-central Chile. In all cases reviewed, characteristics of integrated design were verified to reductions in energy loss and demand. Finally, the procedure implemented was evaluated through surveys of those practitioners responsible for each experience studied.
Findings
This process made it possible to highlight four main features of integrated design, namely, pre-established performance goals, interdisciplinary collaboration, regular broad-ranging meetings and the use of performance assessment tools. With these techniques, reductions of more than 50 per cent in the energy requirements of the housing designs were achieved, while safeguarding the functional, aesthetic and economic aspects of the projects.
Research limitations/implications
However, professionals currently working in this field did express their concern regarding responsibility for the design and the time needed to complete the process.
Practical implications
Furthermore, this experience also identified similar modifications made to the design of the houses, which revealed general possibilities for improving energy performance.
Social implications
The conclusions obtained have been exposed in conferences and graduate programmes and applied in two real projects for the benefit of society: first, the improvement of building envelopes in social housing in Temuco; and second, CASA+, a modular, prefabricated and energy efficient house prototype.
Originality/value
This paper carried out a novel review of an integrated design process in housing cases of developing countries, and identified the key features, which improve the environmental performance of dwellings.

Abstract
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.
