Onnelanpolku – A near zero energy nursing home in Finland
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.
