Šilumos sąnaudos gyvenamųjų pastatų šildymui

Abstract

The main part of the produced thermoenergy is used for building heating. If we want to estimate energy consumption in buildings, we must know its heat consumption for the heating season. This heat consumption we may easly by to calculate if we have heat losses for a statistically normal climatic year. But for houses built ten years ago and sometimes for new building we dont have this data. For this reason these losses it is necessary to obtain using well-knows methods. We may suggest a simple method for heat consumption calculations. It is uses a simplified equations (5,8,12) in which values are obtained by using indoor and outdoor air parameters, for calculating heat losses. According to this dwelling heating are enough exactly and may be used for energy passport of buildings.
