Abstract
Vision Nollenergihus
The vision for zero energy housing
Per Danielsson och Fredrik Helander
Climate change is the modern society’s common issue. The developed countries are consuming more than what is sustainable, and the climate change due to the use of fossil fuels can be seen clearly. EU has specified goals, in order to stop further damage, which demand that every member state have to reduce its energy consumption by 20 % before 2020 and 50 % before 2050, relative to 1995.
The Swedish government uses a number of instruments to encourage reduction in the usage of energy, but every individual has to contribute to reach the goals.
With increasing energy price the cost of living is going up. A lot of people are looking for ways to save energy and not be affected as much by the increasing price.
Investments for insulation, replacement of windows and replacing old heating system for a new efficient heat pump is getting more and more common.
This thesis is about investigating the possibilities in becoming independent from buying energy for households. The thesis describes ways to use and store the abundant solar energy in the summer and transfer it to the winter.
By building a neighborhood with five so called passive houses and having common installations, some costs of the expensive investment can be divided on more than one user. Then if the price of energy keeps on rising, it is possible to get a lower living cost compared to conventional housing developed according to the Swedish BBR demands. This system will become even more profitable when the skills and technology is perfected.
