Abstract
Integrated assessment of buildings involving environmental, social and economic dimensions should be incorporated in sustainability assessment of buildings. Systems and tools used in many countries were based on the Slovak system development. Building environmental assessment system (BEAS) applicable in Slovakia has been developed for evaluation of building performance. BEAS is a multi-criteria system contains fields: site selection and project planning; building construction; indoor environment; energy performance; water management and waste management. Significance weight of proposed six main fields and 52 indicators was determined by mathematical method. Mathematical mechanism for evaluation processes in field of environmental engineering is extensive. There are many methods for determination of significance criteria, significance parameters, control of dependency, tests of sensitivity, etc. For example: Multi-criteria analysis, Analytical hierarchy process, Saaty’s method, Pairwise comparison method - Fuller method, etc. These methods were analyzed and evaluated in the context of environmental assessment requirements and respect to qualitative and quantitative characteristics of determining indicators ranking. Analysis of mentioned methods for criteria weights estimation was performed. Saaty’s method has been used for determining the significance weights of indicators, sub-fields and fields of buildings environmental assessment and seems to be the most appropriate of them. This paper summarizes the analysis of significance weights of energy performance indicators for evaluation of residential buildings. It uses multi-criteria analysis to measure the quality of buildings in Slovak Republic. The presented energy indicators and their evaluations are proposed for the phase of building design. The significance weights of proposed indicators were determined by Saaty’s method of multi-criteria analysis. For the purpose of system verification, a statistically significant set of buildings is required to be evaluated.
