Energy efficient housing: affordable, valuable, comfortable and sustainable
Passive housing complex Lodenareal, Innsbruck
The NHT built 354 passive house rental apartments and the ZIMA 128 condominiums on the 33.000 m2 site. In addition, an approx. 8200 m2 green area of the city of Innsbruck with children‘s play yards and a ball playground was created. The entire planning package is aimed at achiving the strictest passive house standard. The accompanying inspection and certification is carried out by the Passivhausinstitut Darmstadt.
For example, a semi-central ventilation system in each stairway ensures a controlled domestic ventilation, the air preheating occurs with groundwater and the 1000 m2 solar unit covers 55 percent of the hot water requirements. A pellet plant produces the energy for the underfloor heating and covers the rest of the demand for hot water.
