District Energy (DE) systems distribute thermal energy, in the form of steam, heated or cooled water, through a network of pipes. DE is used for space heating and cooling, and providing hot water for use in buildings.
DE systems help to conserve energy through improved efficiency over conventional heating and cooling systems. Also, with the help of DE, we can achieve significant reductions in greenhouse gas emissions by using clean renewable energy sources.
DE systems are compatible with a wide range of renewable energy sources. The DE system uses thermal energy to heat water. Then, the water is distributed to customers through a dedicated pipe network — at either a low temperature (15 to 20 degrees Celsius) or a high temperature (above 60 degrees Celsius). The heat from the water is then used directly to heat dwellings or other spaces through heat exchangers. Or, the water is transferred to the local building heating/cooling system through a heat pump.
