Onnelanpolku –  A near zero energy nursing home in Finland

/in /by

The nursing home, built in 2013, is a near zero-energy building. Onnelanpolku is well insulated and its energy consumption is partially provided by local sources. The hybrid heating system for space heating and hot water was realized with a combination of solar thermal collectors and district heating. Electricity consumption is also minimized by the use of energy efficient ventilation equipment and pumps.

Technical details:

  • GHG savings: 6 816 tonnes CO2-eq/per year
  • Energy sources: solar thermal collectors, district heating
  • Storage capacity: 3×3 000 L water tanks
  • Supplied temperature: maximum 26° C (space heating)
