Architectural Graduate and Integrated Master Studies Director (2005-2009). He is an author of more than one hundred publications. The main research subjects includes lightweight and mixed weight buildings, low cost housing, local and global economic asymmetries, low-tech strategies, energy costs and sustainable development, new materials and technologies, recycling and reusing potentialities.

Speech Title: The importance of the Local Materials and Technologies in the Eco-design of Buildings
Abstract: The environmental conscious design of a building requires considering all the life-cycle stages: materials production, construction, use and end-of-life. The stages of materials production and end-of-life are the ones that generally receive less attention in the architectural design process. The production of the most common conventional materials in developed countries, such as brick and cement, involve industrialized processes that require large amounts of energy and other environmental impacts. These materials are generally assembled in composites and building technologies with a complex life cycle, presenting high embodied energy and pollutant emissions, in detriment to existing alternatives of natural and less processed materials, that characterize vernacular building technologies in undeveloped economies. The maximum use of local and poorly processed materials, as well as local technologies implies a reduction in environmental impacts, but not necessarily associated with an increase in the economic cost of construction. In fact, industrialized countries, with the most advanced and energy efficient technologies available, as well as the scientific knowledge, produce buildings that can be much more energy efficient in the use stage, but also much more expensive and less environmentally efficient in the materials and building technologies involved in their construction stage, and thus less efficient considering the entire life-cycle scenario. Improvements can be achieved by minimizing the use of materials, by reusing, recycling and even reducing the overall weight of the building and lower impacts resulting from the extraction of raw materials, production processes, as well as a proportional reduction of the losses and energy associated with transportation. However, another principle of future action can be a drastic reduction in the use of industrialized materials. This presentation discusses the importance of selecting the appropriate local materials and building technologies, less industrialized, in order to allow eco-efficient choices for architectural design. Some case studies related with researches that are being developed in the University of Minho are presented and discussed in order to illustrate these principles.
