District Energy
Energy
A district energy system consists of a central plant that produces steam, hot water, or chilled water, to provide space heating, domestic hot water heating, and air conditioning. The water or steam is delivered through a network of pre-insulated buried pipes to a clustered community of commercial, industrial, and/or residential customers. As a result, individual buildings don't need their own boilers, furnaces, and cooling systems saving money and energy. When designed with a combined heat and power plant the system can also provide electricity.
