Abstract

This paper presents an overall review and synthesis of building construction studies and activities in the field of Bioclimatic Buildings, carried by an Iberoamerican network supported by the CYTED Program. This network, include Argentina, Brazil, Chile, Ecuador, El Salvador, Mexico, Peru, Portugal, Paraguay and Spain in a total of 14 Institutions. The main goal of this network is to improve the use of renewable in social housing programs as also to improve the design and implement bioclimatic strategies in this type of building in those countries. This project aims also to help to came closer the main actors in the field in order to set up local or national programs in social housing, putting together these actors at national level, developing ideas, projects, legislation, conferences, seminars or networks. During these three years project, an important review of building construction has been set up, discussed and presented in several main seminars (El Salvador, Mexico and two in Argentina). In this paper a national review of projects and building constructions are presented and discussed in most of these countries as also the main ideas and goals for each of the participants.

Keywords: Social buildings, renewable energies, bioclimatic design.

1. Introduction

The Project started in 2005 and was defined a base program with four main tasks: 1) survey and revision of the constructive practices, passive systems and renewable energies use, systematization of the information in order to define, for each country, the sustainable measures to be implemented; 2) thermal performance evaluation of some buildings and systems; 3) development of building guide lines; 4) dissemination actions.

In the first year the participating countries have done a considerable effort in the survey of the case studies and the results were presented in a Seminar, open to all Argentine groups, in October in San Martin de Los Andes. The main results were published in the proceedings “Bioclimatic Buildings in Iberoamerican CountriesWos Edificios Bioclimaticos en los Paises de Ibero America “ [1].

In April 2006, at El Salvador, a Seminar was undertaken on “The use of solar energy in social buildings “Uso de la Energia Solar para Viviendas y Edificios de Interes Social” and in the CYTED meeting was decided that all groups should be familiarized with buildings thermal and energetic simulation methods in order to evaluate the thermal behaviour of the social houses case studies selected. For that purpose was organized in June, at University of Sao Paulo, a Workshop in order to allow to all the network groups evaluate the thermal performance of the implementation of the corrective measures namely at the building external envelope. Three months later, at Buenos Aires, a

CYTED meeting was undertaken in order to discuss the first simulations results and to overcome the difficulties founded by each group.

In 2007 two Seminars of dissemination and technological transfer were done, one in June Mexico D. C. under the titles “Social Buildings in Iberoamerican countries’Yos Edificios de Interes Social en Ibero America” and the other in November at San Luis, in Argentina, “Buildings in the Future, Bioclimatic Strategies and Sustainability’Yos Edificios en el Futuro, Estrategias Bioclimaticas y Sustentabilidade” [2].

This year a Seminar will take place at Lisbon in next October open to all the scientific community and also the final meeting in order to make the balance of the network contribution in each participating country. The network in all countries wherever organized seminars always meant to be open to others groups and to promote and enhance discussions of these subjects.
