"Vaznost pravilnog projektovanja objekata za obnovu, izgradnju i razvoj Bosne i Hercegovine (Uslovi koji moraju biti zadovoljeni pri projektovanju, gradjenju i rekonstrukciji stambenih objekata)";
Talk: Prvi kongres naucne diaspore, Sarajevo - Bosnien und Herzegowina (invited); 2006-09-14 - 2006-09-17.

In the whole world the evolution is characterized by a bigger and bigger use of energy. Great efforts exist to lower the energy consumption but the possibilities are still up to now very small. The analyses in the European Union to estimate the increase of energy consumption show in the nearest 30 years an increase of 30 percent.
The decomposition of the energy consumption indicates that in addition to the industry and the traffic a great part of energy is used for houses and buildings. The result of an analysis of the energy consumption in residential and commercial buildings in the countries of the European Unions is that more than 50 to 75 percent is used for the space heating. This part can be reduced relatively easily if the heat insulation of the buildings will be better and the heat losses can be reduced.
A lot of investigations were done and many experimental buildings were examined to reduce the energy consumption. The result is that one can reduce the heating energy effort so drastically, that one almost needs no energy to achieve a sufficiently comfortable indoor air temperature.
Passive house is a building, in which a comfortable temperature can be attained both in the winter and in the summer without separate heating and/or air conditioning system. It offers increased housing comfort with a heating energy requirement of less than 15 kWh/(m²a) and a primary energy need inclusively the energy for domestic hot water and electricity of under 120 kWh/(m²a). The passive house is a consistent further development of the low-energy building (NEH). In the comparison to the NEH a passive house needs only 20%, compared with a conventional building only 10 % of the heating energy. Converted into fuel oil a passive house gets along in the year with less than 1.5 l per square meter bet floor area. This saving reaches the passive house alone by its both basic principles: Avoid heat losses and use free heat gains! Passive houses are under energetic criteria the housing standard of the future.
