District heating and cooling, demand management and energy storage

District heating and cooling (or District Energy) is common in Europe, Asia and North America. It involves the thermal demand for more than one building being served by a central energy centre. The greater economy of scale allows for innovative technologies that reduce greenhouse gas emissions, increase energy efficiency and reduce long-term energy costs. Examples of such innovative technologies are Combined Heat and Power (CHP), absorption chillers, recovery of industrial waste heat, biomass and thermal storage to reduce peak demands.
