Environmental impact

Green building has come to be a goal of building design now. Since sustainable performance of building involves lots of aspects, an integrated index is needed to evaluate it comprehensively. Building environmental impact assessment (EIA) based on life  cycle assessment (LCA) theory is a well-known method to do this.

During the design process of heating systems, the designer must analyse various factors in order to determine the best design options. Therefore, the environmental aspects of a product should be included in the analysis and selection of design options if an environmentally - aware design is to be produced. If one wishes to assess a products environmental impact, its whole life cycle must be studied. The Life Cycle Assessment (or LCA) methodology is an example of one kind of environmental analysis which included the entire life-cycle of a product. However, this method has some limitations.
