Lead partner of the EEBAK project, Lapland University of Applied Sciences (Finland), has shared information from 3 pilots they have been developing during the last months in Sweden:

1. Lusthusbacken (Four smaller residential apartment buildings in Piteå, owned by Polarrenen AB): 
  • Residential buildings that does not only consider the energy for usage, but also the materials used for the building.
  • Materials used are all renewable material. 90% of the buildings are made of wood.
  • 24 apartments in total.
  • Finished in 2018.
  • Focus is energy usage and see how well the building performs.
  • Brief overview of the indoor thermal climate.
  • Brief overview of the materials used, performance of them and evaluation of the buildings, (LCA).

2. Stadstornet (High rise residential apartment building in Piteå, owned by Pitebo):
  • Low energy building with “silver level” as an aim (in accordance with Swedish energy standard). 
  • 16 floors in total, with 60 apartments.
  • Finished in 2017.
  • Oval building that should be optimal from an energy point of view.
  • Approximately 70% of the envelope is covered in glazed balconies, which extend the building envelope.
  • Focus have been measurement of energy usage and to see how the glazing affect the building.
  • Brief overview of the indoor thermal climate to see if the large glazing section affect the apartments (e.g. temperatures in different cardinal directions and levels, can we see how the sun affect the apartments during sunrise or sunset).
  • Brief overview of the planning of the building and how energy calculations can affect the results.
  • Data from occupants experience of the building. 

3. Sjunde Huset/The Seventh House (Semi-detached residential building in Kiruna, owned by Kirunabostäder):
  • Pilot building to demonstrate how to build a passive house standard in the sub-arctic climate in Kiruna.
  • Demonstration of an air heating system for the entire building, no hydronic radiator heating system.
  • Finished in 2014.
  • Focus have been measurement of energy usage and indoor thermal climate, to evaluate the whole building.
  • Data from occupants experience of the building. 
During EEBAK project progress partners have shown that it is possible to have an air heating system and create a good thermal indoor climate for this type of building, and provided guidelines on how to design the system, along with important aspects to consider.
