In Switzerland more than 40% of energy consumption and CO2 emissions can be attributed to building heating and hot water production, 65% of which is for private households. The heating costs burden the household budgets and emissions pollute the environment. It is necessary to reduce CO2 emissions and the dependency on fossil fuels and hence other nations. Saving electricity is also a hot topic, since Parliament has decided to phase out nuclear energy. One obvious local and renewable energy source is wood, but the annual growth of 10 million cubic meters is not enough in order to close the gaps, even though only half of that annual growth is currently used. For these reasons, it is necessary to pay particular attention to the following objectives when considering building heating systems:
Expanding the use of renewable energy sources: solar, heat from soil, water and the atmosphere
Improving efficiency when consuming oil, natural gas, biogas or wood
Renovation of buildings that consume too much energy - 60% were built before the first oil crisis and are particularly poorly insulated
Promoting the development of district heating systems in urban areas
Planning with the use of locally available renewable energy sources, which vary from region to region
The appropriate choice of heating system depends on the property, the locally available energy sources and geographical location.
