EU Heating and Cooling Strategy

On 16 February, the European Commission launched its first ever strategy to tackle the massive use of energy, particularly fossil fuels.

Heating and cooling accounts for 50% of the EU’s energy consumption and renewables account for just 18% of this. The strategy includes plans to boost the energy efficiency of buildings, improve linkages between electricity systems and district heating systems which will greatly increase the use of renewable energy, and encourage reuse of waste heat and cold generated by industry.

District Heating and Cooling

District heating is a heating system consisting of a pipe network, filled with hot water, and heat sources (from residual heat or a heating plant). The hot water is circulated by pumps, from the heating plant to the client and back again to the heating plant. A heat exchanger at the customer transfers the heat from the district heating network to the building’s own heating and hot water systems. The return water continues out through the return pipe and is pumped back to the heating plant, where it again is heated.
