The main concern of this research is building refurbishment. Different possibilities of energy performances improvement of existing dwelling housing in the settlement Konjarnik, Belgrade, Serbia, are estimated from energy and economic point of view. Two hypothetical models of improvement of building envelope are created. Different solutions for reduction of energy consumption for heating of existing dwelling housing as well as reduction of CO2 emissions are considered in economic analyses. Economic analyses use BLCC (Building Life Cycle Cost) software which produces multileveled grading of building scenarios and comparative analyses of grading results. The comparative analyses take into account initial building investments and energy cost savings through certain period of building`s use. The overall behaviour of different scenarios is measured according to: (a) initial/capital investments, (b) energy costs (c) operating, maintenance, and repair (OM&R) costs and (d) capital replacement ...costs. Results of the analyses are used as quantitative inputs for investment decision making.
