Good Practice Information

The Helen District Heating and Cooling system uses waste heat from a data centre to provide heat, sea water to provide cooling as well as heat pump and absorption techniques.
The system was pursued in order to: 1)To improve energy efficiency and RES uptake (target 38% by 2020), 2) target for zero CO2 emissions by 2050 contain energy costs, 3)benefit from co-location of activities & innovative technological opportunities.
The objectives of the project are : Utilise energy-release intensity from datacentres (DC) for district and cooling (14 000 customers).
Importnat background facts include: 1) District heating network exists; 2) SEAP, 3) Demand – led approach towards energy efficiency; 4) Long history in PPP and ESCO solutions.
The beneficaries include: Homes and businesses in the Helsinki central area, who are part of the district heating network.

Evidence of success

CONCEPT: Solution demonstrates circular economy. Energy costs have decreased as heat from Academica DC is free for Helen, thus benefitting citizens at no additional costs. RES % participation increase: Producing district heating is 80% from renewable energy. Technological innovation: Existing equipment have been combined and used in an innovative way (simultaneous heating and cooling pump).
