Retrofitting of multifamily housing: life-cycle costing aspects

Abstract

This Life-Cycle Costing (LCC) analysis deals with the feasibility of measures taken to improve thermal performance of building envelope in order to reduce energy demands for space heating. LCC analysis is carried out on one exemplary apartment in multifamily buildings with recently refurbished facades in Karaburma, a settlement in Belgrade. Results of the analysis show that by improving properties of envelope with poor thermal U value, the reduction of electricity consumed for heating in Belgrade climate is 28 %. Considering Serbian system for electricity charging, reduction of monthly costs for electricity can be doubled.
