National project

The main objective of the Finnish "HP4NZEB"-project is to outline energy and cost efficient nearly zero energy building solutions utilizing heat pumps in Finland.

The project consists of energy and cost efficiency optimization in three building types:

  1. Apartment building (new building in planning phase)
  2. Detached house (new building in planning phase)
  3. Apartment building (existing building that is being renovated)

The project work includes defining and outlining the energy and cost efficient solutions for building services, structures and renewable energy production. The heat pump types researched are ground source heat pump, air source heat pump and exhaust air heat pump. The outlined concepts' demand for heating, cooling and electricity consumption will be simulated in all three building types with three different scenarios: the "traditional" level (2012 level) and two nearly zero energy levels - the Finnish NZEB level or the passive house level defined by the Technical Research Centre of Finland VTT.
HP4NZEB project includes the following tasks:

  1. Definition of the state-of-the-art in Nearly Zero Energy Buildings in Finland.
  2. Description of concepts incorporating heat pumps (3 building types) and assessment of their energy consumption demand.
  3. Assessment of energy costs of different nearly zero energy concepts incorporating heat pumps.
  4. Preparation of new project concept for field evaluation project.
  5. Conclusions and recommendations on heat pump use in NZEB in Finland.
  6. Project dissemination.
  7. Project coordination.

The main outcome of the project is to outline what is achievable "nearly zero energy" level in Finnish circumstances when it comes to concepts utilizing heat pumps.

The Finnish project is implemented by Green Net Finland (coordinator), Aalto University, VTT and the Finnish Heat Pump Association Sulpu. The project is funded by the Finnish Funding Agency for Innovation Tekes and the consortium of ten Finnish companies:

  1. Ensto Oy
  2. Suomen Lämpöpumpputekniikka Oy
  3. Oilon Oy
  4. Rettig Oy
  5. Scanoffice Oy
  6. Kaukomarkkinat Oy
  7. Nibe Oy
  8. Fidelix Oy
