  5. Different operatingfigures • HWB – specific heating demand: Before: 235,61 kWh/m²a After: 46,75 kWh/m²a • U-value – heat transfer coefficient: Before:1,86 W/m²K After: 0,40 W/m²K

  9. passive house standard I • good concept to save energy • annual heating requirement that is less than 15 kWh/(m²a) • not necessary to use any active energy for heating or cooling systems • combined primary energy consumption of living area of a European passive house may not exceed 120 kWh/(m²a) for heat, hot water and household electricity

  13. Europe’s largest passive-house estate • Located in Innsbruck • 354 apartments & 405 basement parking lots • Minimize energy costs for tenants • Heating demand below 10 kWh/m² • Energy demand only 20 % of average

  14. Europe’s largest passive-house estate • 680 tons CO2 reduction/year • Regional pellets • Solar energy • Ground-water heat • Energy efficient components Source: Neue Heimat Tirol, 2009
