Helen District Heating and Cooling: District heating from the waste heat of the data center and district cooling from the sea water, heat pump and absorption technique.
Topic of the practice
Energy efficiency, renewable energy
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).
