Measures

The hall of residence was given a radical refurbishment and simultaneous energy-saving renovation in two phases. The first phase converted the building into a low-rise structure, while the second brought it into line with the standards of a passive house.

Key points:

  • Insulation
  • Curtain wall systems
  • Windows and glazing
  • Ventilation and heat recovery

Energy Savings

Renovation cut the primary energy consumption by more than 60% to 80 kWh/m2a. After the first phase alone, the heating requirement fell by approximately 58% to around 68 kWh/m2a. The renovation to bring the building in line with passive house standards should reduce it further to 26 kWh/m2a. The renovation reduced total energy costs to just 15 Euro/m2a and the total cost of electricity to 6 Euro/m2a.
