Tiivistelmä
Every year the price of heating in Russian Federation is getting higher and higher. Because of this residents think energy efficiency in their houses to save money. In the nearest future some measures must be done about energy efficiency. One of these measures is refurbishment. During the refurbish-ment with improving building envelope, windows and joints; we can achieve well-done construction with lower losses and reduce energy consumption. It is the most common way to reduce energy con-sumption in residential buildings built between 1960 and 1990 years.
The aims of this work are: to know, what the energy consumption building has now and how it will change after refurbishment; to calculate the investment part of changes in envelope which include cost of materials and installation works; to find out how long payback period of renovation will be.
In order to reach specified aims the following methods are applied. The first method is literature re-search. Method of analysis and description of the building envelope will be applied. Secondly heat losses will be calculated for existing building. And for three more models after refurbishment: with new parameters of glazing, with adding insulation and with full refurbishment with insulation and glazing. Only insulation and glazing will be chosen because they are easy to change and convenient to reinstall. Next goes analysing of energy consumption before and after the renovation, which will be calculated with IDA ICE simulation software. In the end formulas of investment efficiency will be applied to find out the payback period.
This thesis describes several of refurbishment models which lead to energy saving. In this work dif-ferent models are compared to find out the most significant and efficient variant both for energy saving and for residents’ budget.
