I+R Gruppe, Lauterach

The first platinum-certified office building in Austria - thanks to the use of innovative building services.

The goal:

  • LEED certification “Platinum”
  • Use of innovative building services systems
  • Complete building in passive house quality

Our solution:

  • Cooling and heating supply exclusively by means of a reversible heat pump system
  • Energy source required to operate the heat pump via a geothermal probe system through 10 boreholes, each 150 m deep
  • Free cooling operation of the geothermal probe system - in winter it serves as an energy source for heating, in summer as a direct cooling source
  • A dry re-cooler is used for heat dissipation in cooling mode
  • Static floor heating/floor cooling - a single system with dual use
  • A mechanical ventilation system controls the aeration and ventilation
  • Air volume control via variable volume flow rate regulators
  • For the flexible office axes, the air volume can be2 adapted to the existing workstations for an area of 60 - 70 m
  • Heat recovery from the exhaust air using highly efficient rotary heat exchangers

The data:

  • Heating and/or cooling capacity of approx. 115 kW
  • Geothermal probe system with a total of 1,500 running metres
  • Air quality measurement for the maximum CO2concentration of 800 ppm
