The Extensive Analysis of Circumstances Between Heat Consumption of Multi-apartment Buildings and Information Campaigns

Abstract

The article presents the analysis of the heat energy consumption for the fifty multi-apartment buildings. The analysis of the heat energy consumption has been made based on the real measured data in the period from year 2011 till the year 2015. For the last five years, building energy efficient topic has become more and more actual. Various governmental institutions, private companies and NGO had realized massive information campaign since 2010. However, the number of fully renovated buildings is very low. For example, in Riga less than 1% of multi-apartment buildings have been renovated since 2010. In the most cases buildings’ owners have replaced the old windows implemented local energy efficient measures such as hydraulic balance of heating and hot water systems, sealed entrance doors and windows in staircases etc. Moreover, the inhabitants have improved their habits and are able now to control their heat energy consumption. Information campaign have resulted in better understanding of the heat energy consumption, hot water consumption, ventilation principles etc.This study shows the dynamics of heat energy consumption during the last five years and analyzes how the minor technical improvements and behavior change have effected buildings’ heat energy consumption.
