Austria: Establishing a maximum allowance of carbon dioxide emissions leads to the use of solar heat

For the first time in Salzburg and Styria new building regulations are in force requiring the use of solar heat or other renewable sources for water heating in new buildings. An alternative option is the purchase of renewable district heat.

The new regulations require the proof of low CO2-emissions in the heat supply. Exceptions are made when district heat from renewable energy sources or from highly-efficient CHP is purchased. However, also a complete exception can be effected if the use of renewable energies is proofed as uneconomical. The requirements in Salzburg for new buildings were extended regarding passive solar gains and maximum allowed CO2-emissions of heating installations. Accordingly the use of an oil or gas boiler without a solar heating system will be impossible.
