Finland: From Advice to Action

29 October 2025
Technical details

The story of energy advisory services in South Karelia began in 2012. Since then, the service has operated as a regional one-stop shop (OSS), coordinated by the city of Lappeenranta. It was launched in response to a clear regional need for comprehensive and impartial energy advice for residents, municipalities, and businesses. The initial development was supported by the European Regional Development Fund (ERDF), which provided crucial funding for building a robust service model. After the project phase, continued financing has come from the city of Lappeenranta, Motiva, and the Finnish Energy Authority (Energiavirasto).

Helping All Sectors Take Energy-Smart Steps
The core mission of the South Karelia Energy Advisory Service is to provide unbiased, non-commercial advice focused on sustainable energy use and efficiency. The service supports various user groups—from families seeking to reduce energy bills, to municipalities planning green transition steps, and to businesses improving energy performance. The advisory team also plays an active role in public awareness, regularly organising workshops, seminars, and information campaigns to educate
people about energy efficiency and sustainability. These efforts have helped create a culture of energy awareness across the region, empowering individuals and organizations to take meaningful action.

A Forum for Sharing and Growing Together
In 2021, a local collaboration forum was established to provide housing associations with a regular space to exchange experiences and promote energy efficiency. The forum has proven especially useful for associations facing similar renovation or renewable energy goals. As a practical outcome, energy audits were conducted for 13 voluntarily participating in private multi-apartment buildings by the end of 2023. Based on the results, group procurement activities began in 2024.

From Thermal Cameras to Tailored Advice
Among the most popular services today is the free lending of thermal cameras, which are used to detect heat leaks in buildings. Two cameras are available, and residents can reserve them by phone, e-mail, or in person. Instruction materials are provided to ensure efficient use. Additionally, energy advisors are available to give presentations at events, tailored to the needs of each audience. For municipalities and SMEs, the current advisory focus is on energy efficiency agreements, energy surveys, and financial support opportunities.

South Karelia’s regional energy advisory service offers practical, impactful support that contributes to Lappeenranta’s ambitious goal of becoming carbon neutral by 2030. The model continues to inspire similar services in other regions.
