According to the mutual agreement the energy efficient building is using not more than 30% energy comparing to the standard heat demand at the building that is fullfiling the minimal standard of building regulation.

The energy efficiency is achived by:
• thermal insulation of external walls - min. 30 cm thick ,
• windows and doors with high energy standard,
• controlled and adequate ventilation,
• advanced system for using renewable energy,
• heat pomp as an option,
• heat recovery from domestic sevage.
