Additional costs detached house Standard vs. Green Building / passive house Green buildings: Energy saver costs detached house Standard* costs Green Building/passive house (PH)** Because of the optmized thermal insulations, green buildings/passive houses do not need traditional heating in Winter 39.000 EUR or cooling in summer. They work with a balanced ventilation system, which allows in summer an air supply with fresh 40.000 EUR and cooled air and in winter preheated air. To achieve this, green buildings work often with geothermal energy, e.g. 35.000 EUR ground source heat pumps. 30.000 EUR 25.000 EUR 25.000 EUR 20.000 EUR Principle of ventilation systems in the passive house 14.800 EUR 15.400 EUR 15.000 EUR Air change instead of aircirculation Reduction of humidity 10.000 EUR 10.000 EUR 10.000 EUR Clean indoor air Minimized cooling 5.200 EUR 5.000 EUR 5.000 EUR 3.600 EUR 0 EUR Ambient indoor climate 0 EUR insulation roof/ windows ventilation system additional investments: total oil tank, boiler, radia- walls/bottom plate tors, distribution lines difference (detached standard) Energy for heating/cooling kWh/m² (year) vs. Reheater (PH) 14.000 EUR *according to German „Energieeinsparverordnung (EnEV) 2009“ **figures German Passivhausinstitut Darmstadt 2010
