Abstract:
The energy used in buildings represents a large share of national energy use in most countries, so one of the conditions for the reduction of total energy consumption has become improvement of the energy efficiency in building sector. Understanding of the buildings energy performance at the city level is necessary in order to form a city energy planning policy and make a strategic decision on which buildings should be thermally improved. In this paper, the impact of new windows installation on the heating energy consumption of a multi-family residential building sector, built before 2012 in the city of Kragujevac, Serbia, was investigated. Heating energy consumptions and reductions were estimated by engineering bottom-up method which uses representative building types and building energy simulation program. After the simulation of the new windows with U=2.2 W/Km2 and U=1.4 W/Km2 installation, the reductions of the total annual heating energy consumption of a multi-family residential building sector were 15.97% and 19.26% respectively.
