Pilot manager: Enespa Ltd, Finland

This pilot aims to stimulate homeowners to make investments that promote energy efficiency and reduce CO2 emissions.  The focus is on existing detached houses. In particular, the pilot explores the possibilities to develop a shared heating infrastructure for multiple detached houses in a residential area.

The pilot focuses on developing a model for the promotion of energy saving and carbon emissions reduction in detached houses. The pilot is located in Mynämäki, a rural municipality that has made a commitment to become carbon-neutral. The pilot is run by Enespa, which is Finland’s oldest ESCO company.

Residents are supported by home audits, meetings, technical and organisational support, and support for organising funding for the investments.  


The main objectives of the project are


  • to create awareness and stimulate discussion on homeowners’ possibilities to reduce CO2 emissions + to inform households about their possibilities to re-duce energy consumption·
  • to develop and disseminate unbiased, locally relevant information on the best energy efficiency and heating system options from a CO2, cost and user per-spective·
  • to explore the possibilities for a shared heating infrastructure for multiple de-tached houses in a residential area·   
  • to explore the possibilities for a resident-based organisational structure (co-operative) to own and manage the new heating infrastructure·   
  • to engage local households in planning and investing in the new heating infrastructure·
  • to develop and test the accuracy of a simplified energy auditing scheme·
  • to better understand the potential of third-party ESCOs within the residential sector ·   
  • to contribute to better understanding of the significance of a radical social initiative such the "Carbon-Neutral Municipalities" initiative + to gain knowledge to what extent such initiatives are able to invoke critical social momentum and change the way energy efficiency improvements are dis-cussed and decided upon.

Regional scope   

Local (Housing area Raimela in the community of Mynämäki)

Target group   

Residents of a housing area in the community of Mynämäki. The respective houses that are subject of the project were built mainly in the early 70s, no major renovations have been made, no district heating is available, and most are heated by oil. The municipality is also the target group as it owns and markets building sites in the area.

Type of intervention   

  • Organisation of meetings and home energy audits with the residents and key stakeholders such as municipality representatives, the bank, and – at a later stage – maybe also with equipment suppliers.
  • The main instruments are information, audits, technical and organisational support as well as support in obtaining finanance.
