Abstract

The paper describes the impact of factors which influence the buildingпїЅs energy consumption. Building constructions are important factor that influences total energy necessity for heating, where energetic efficiency presents way to better competition, since it decrease service costs. Building is greatest consumer of energy and here lies also potential of rationalization of energy costs. During quantification of energy savings there were used two methods: upside down пїЅ evaluation of savings through obligatory indicators in individual sectors of national economy and bottom-up пїЅ detail evaluation of individual projects. We considered with projectпїЅs financing from own sources. Choice of optimal variant had been made by the way of basic variant. From the view of economical evaluation we calculated net present value, and by this way we discovered project with complex renovation of building presents optimal variant that shows better preferences. Realization of measurements can help to achieve decreasing of energy consumption, as well as costs on energy. There is immediately achieved total costs savings, and by this way payback period is shortening.
