AN APPROACH TO MULTI-ATTRIBUTE ASSESSMENT OF INDOOR ENVIRONMENT BEFORE AND AFTER REFURBISHMENT OF DWELLINGS

The paper analyses the correspondence between the present state of indoor environment and needs of habitants and the Lithuanian Hygienic Norm. To investigate the correspondence the authors (a) distinguish measures (attributes) of evaluating dwelling houses and their importance, (b) choose a method of processing the values of attributes, (c) choose a method of evaluating the efficiency of refurbishment and/or renovation of a building and (d) investigate dwelling houses in Naujoji Vilnia and evaluate the efficiency of refurbishment and/or renovation. As a result of the analysis the authors propose an approach to multi-attribute assessment of dwelling houses before and after refurbishment and/or renovation and evaluation of its efficiency. The experiment results, obtained by measuring five dwellings in Naujoji Vilnia, show that the renovation process was the most efficient for the second dwelling.
