Abstract
The energy issue has in recent years become a hot topic around the world. Discussions about how to reduce the greenhouse gases in a sustainable manner have been raised. Given that this is an emerging problem, and that many people lack knowledge regarding this subject, it is about time that they get the information needed to be able to contribute in some way. In general, the building sector represents a high proportion of the total energy consumption in all countries. By letting people get acquainted with the benefits of building energy-efficient, the building sector would be seen as a major contribution towards reducing the overall energy consumption in a country. In this report we have chosen to take a closer look on two houses, one in... (More)
The energy issue has in recent years become a hot topic around the world. Discussions about how to reduce the greenhouse gases in a sustainable manner have been raised. Given that this is an emerging problem, and that many people lack knowledge regarding this subject, it is about time that they get the information needed to be able to contribute in some way. In general, the building sector represents a high proportion of the total energy consumption in all countries. By letting people get acquainted with the benefits of building energy-efficient, the building sector would be seen as a major contribution towards reducing the overall energy consumption in a country. In this report we have chosen to take a closer look on two houses, one in Poland and the other one in Kosovo. At present, 40 % of all houses were built during the 1970’s in Poland, with an older building technology. By improving such a large amount of buildings, positive results can be achieved energy wise. After the war ended in Kosovo in 1999, thousands of housing units have been built all over the country in an expedited manner. Most of the houses are poor from an insulation point of view, therefore it is important to provide them with a basis of the benefits when building energy-efficient. We began by studying the thermal performance of the two houses, to be able to see what errors that gave increased energy consumption. From there we came up with various improvements that we later on simulated in a program called DEROB-LTH. This program provided us with values of how much each improvement contributed in reducing the use of energy. Calculations of how much it costs to implement the proposed improvements were also made. All materials that we used in our improvements are available in respective countries. The results that we received were found to have a long payback period if the house was already relatively well insulated. On the other hand, if the house was poorly insulated we received a payback period that should be taken in consideration. (Less)
