Establishment of potentials for building energy efficiency improvement by thermo graphic snap shooting
Abstract
Thermo graphic snap shooting of buildings as a method of detecting building envelope heat losses is a rather new method. By thermo graphic camera snapshots it is possible to detect elements of building envelope without thermal insulation or with a poor thermal insulation as well as crakes around windows or in the construction which cause high heat losses. Once, when the causes of thermal losses are detected, it is possible, through the process of reconstruction or refurbishment, to improve thermal characteristics of the buildings. Usually, thermal insulation is added on the facade, windows are changed with new once with better thermal performances and better air tightness, second or third glass pane is added, metal constructions with thermal bridges are removed... Thermo graphic snapshots analyze also enables architects to avoid mistakes in designing new buildings. Several buildings in New Belgrade were photographed with thermal vision camera and the analyze of snapshots is presented In the paper. The chosen buildings, as representatives of specific construction method, were built in the period from 1950. to 1960., when according to the regulations, application of the thermal insulation was not obligatory. As more than 25% of buildings in Belgrade were built in that period, those buildings represent a great potential for energy saving through the process of refurbishment.
