| Building type: | apartment house (Passive House new build) | |||
| Project description: | The Passive House Institute has issued a Passive House Certificate for the rehabilitation services building Panara, the first certified Passive House in Lithuania. Built in 2011/2012, this
residential project faced two main challenges: First, the severe climate conditions, as it is situated in Panara village in the Varena region, one of the coldest parts in Lithuania. Second, the urban planning conditions, which demanded the builings style to follow the traditional, typical form and material finishes. Airtightness requirements 0.46 1/h average of under and over pressure test results is well below the threshold. A heat pump combined with solar DHW provides the energy for the 600mē (TFA according to PHPP) building | |||
