IMPACT OF LIFE CYCLE ASSESSMENT IN CONSTRUCTION COST AND ENVIRONMENTAL IMPACTS

Life Cycle Assessment is a tool to assess the environmental impacts and resources used throughout a product’s life cycle, In spite of this progress in developing methods and tools to support sustainable building design, there is still a lack of a formal approach to bridge gap between the traditional buildingengineering disciplines, and between these and the architecture, to achieve the level of building integration required for sustainability. This paper presents an integration framework that aims at facilitating the inclusion of life-cycle considerations in the design process from the outset, so thatmaterials and systems are selected not only from environmentally friendly resources, but most importantly, to match service life performance expectations. The iterative methodology to evaluate these expectations in practice which is based on an understanding and modelling of the dynamics of the builtenvironment to materials, components, and systems are exposed. Quantitative methods and test protocolscan be incorporated into the framework for assessing function-performance aspects of alternative solutions. Due to its complexity stemming from its inherent exposure to variable environmental loads andits multi-functionality, the framework focuses on addressing the life cycle of the building enclosuresystem. It is expected that the organization of the underlying principles of building life-cycle performance described in this paper will become a knowledge core that will impact of human life-cycle assessment to building architecture design for reduced embodied traditional and environmental impacts
