Why District Energy
Click
on image for district energy schematic pdf (1.2MB)District energy is an energy-efficient, environmentally sound method of heating and cooling buildings. District energy systems produce steam, hot water and/or chilled water at a central plant. The steam or chilled water is then piped underground to individual buildings within a specific area for space heating, cooling or industrial use. In San Diego, we operate a district cooling system that distributes chilled water. The district cooling technology offers many benefits: Reliable. Staffed 24 hours a day by district energy professionals, and with backup systems readily available, our system operates at well over 99 percent reliability. More … Lower life-cycle costs. With district cooling, buildings no longer need their own chillers. That means less capital investment, less risk and lower ongoing operating, maintenance and labor costs. Fuel and energy costs are often lower too, thanks to volume purchasing. More … Environmentally sound. District cooling systems employ stringent emission controls that help improve air quality. With no need to store fuels, chemicals or refrigerants on site, buildings on district energy systems are environmentally safer. More … Energy-efficient. Chilled water arrives at customer buildings ready to use and 100 percent efficient ‘at the door,’ compared with considerably lower efficiencies of in-building energy systems. More … Easy to operate and maintain. Without
on-site chillers, building managers and staff have far less energy-related
maintenance, monitoring and repairs
to worry about. They can focus instead on their tenants. Comfortable and convenient. District cooling ensures that building occupants can be kept comfortable year-round. More … Flexible. Without the need to accommodate chillers and cooling towers, architects have more flexibility in designing or renovating buildings served by district cooling systems. More …
