Exploring the need for an evaluation model to assist in the eco-efficient selection of building systems

Abstract

With the current practices in architecture and construction, buildings use more than a half of the energy consumed in the world. Designers have an important stake in this respect, being of great importance the selection of materials and building systems. The objective of this paper is to explore the need of assisting in the eco-efficient selection of building systems and to propose an evaluation model with this purpose. A bibliography analysis of norms on the protection of the environment, a study through questionnaires, and a bibliography analysis to study the theoretical base for the decision model proposed are realised in this paper.
