Tiivistelmä
There are a lot of different ways and technologies of saving energy. But if the idea is to minimize costs for energy consumption, the best solution is to find out how to make the whole building energy smart and improve not the energy efficiency of some system or equipment but improve the building`s energy efficiency in a complex way. One of the modern ways of improving the energy efficiency in general is a passive house technology. The idea of a passive house is the economic minimization of heating energy demand during the wintertime and minimization of cooling energy demand in summertime with providing good indoor climate, comfort conditions and good indoor-air quality.
The aim of the thesis is to find out how to make energy consumption of the building as small as possible with the lowest E-value and net purchased energy. There are lot of factors which has an effect on the energy consumption and it is difficult to take into account all them then calculations are carried out manually. In this case computer simulation can be applied.
In this bachelors thesis single-family house with the floor area 150 m2 with the smallest possible E-value will be planned and designed using simulation tool IDA ICE 4. First the main features and aspects of passive house design will be defined in the theoretical part of the thesis using the articles and literature. When the concept of low energy building will be shown and study cases will be described.
After that according to computer simulation the best solution for one-family house with as low E-value as is possible to achieve will be found using IDA ICE simulation tool out by changing
•shape of the building
•air tightness
•area and direction of the windows (area of the windows 12 – 20 % of floor area)
•glazing type
•solar shading (shadings around the site and in windows)
•heat source
•type ofheating systems
Finally the resulting E-value of the best-case building will be compared with the several energy certificates and the recommendation for the passive house and low-energy building design will be given
