District Heating and Cooling combined with renewable energy sources such as an integrated Cogeneration Plant can help meet rising urban energy needs for increased energy security. These systems are thermal energy networks that distribute chilled water and steam via insulated pipes to serve commercial, residential, institutional, and industrial energy demands for space cooling, heating and industrial purposes. As a result, individual buildings served by a district energy system don't need their own boilers and chillers. District Heating and Cooling systems permit energy, as distinguished from fuel, to be bought and sold as a commodity.
District Cooling systems have several attributes that give them an advantage under certain conditions over conventional energy systems. By replacing many individual air-cooled split units from the individual building chiller system with one central cooling source, results in: -
- Cost benefits from substantially lower electricity usage;
- Increase effective building space by individual set up for each building;
- Decreased lifecycle/reduce building construction and operating costs;
- Minimize the negative impacts of energy production, transportation, conversion, utilization and consumption on the environment.
- Lower maintenance;
- Improved air quality.
