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 I...n 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.

Primena termografije u građevinarstvu kao metoda za ocenu toplotnih karakteristika zgrada je relativno nova. Termografskim snimanjem moguće je konstatovati neizolovana ili slabo izolovana mesta omotača, kao i mesta produvavanja kod nezaptivenih prozora ili fasada koja predstavljaju izvor najvećih toplotnih gubitaka. Na taj način kod rekonstrukcije zgrada potrebno je upravo intervenisati i posebno obratiti pažnju na takva mesta, a pri projektovanju novih zgrada izbeći postojeće greške iz prakse. U radu su prikazani termografski snimci više stambenih zgrada iz Beograda i izvršena je analiza dobijenih rezultata, odnosno konstatovana su mesta sa najvećim toplotnim gubicima. Analizirani objekti su iz perioda u kome je u Beogradu izgrađeno više od 25% danas postojećeg fonda a primena termoizolacije nije bila uslovljena važećim propisima, pa bi ovi objekti, kroz eventualnu energetsku rekonstrukciju, mogli da doprinesu značajnoj uštedi energije.
