MULTI-ATTRIBUTE ANALYSIS FOR THE ECO-ENERGETIC ASSESSMENT OF THE BUILDING LIFE CYCLE

In the recent years, attention has been attracted to the development of activities (developing and implementation of standards, directives, regulations, policies etc.) related to the environmental protection and implementation of the principles of sustainable development. Also in Poland, principles of that concept are Put into practice. There is, however, a shortage of elaborations which the future investor or designer could, in an easy way, utilise for the selection of environment-friendly materials, technologies, building utilities and so forth, i.e. to design a facility which causes the least harm possible to the environment, maintaining at the same time low energy demand during its life cycle. According to the philosophy of environmental protection, a building design should take into consideration its entire life cycle, and its structure and utilities should allow the supplies of energy needed for heating to be eliminated while using the building. The present paper aims to give multi-attribute analysis for assessment of building variants, which utilises the Life Cycle Assessment method (LCA). The method defines a number of so-called environmental impact categories, which include criteria to be considered while selecting a solution, which minimises such impacts. The most important of them and costs are taken into account in the multi-criteria analysis for optimum solution selection. The results of eco-energetic assessment of variants house are grounds to supporting decisions in programming, designing and performing houses, taking into consideration numerous others aspects (usable, technical, social etc.).
