Annually since 1990, the International District Energy Association (IDEA) has polled its member district energy systems to report the number of buildings and their area in square feet that have been committed or connected to district energy service during the previous calendar year. IDEA compiles this information as well as the thermal energy services provided (heating, cooling, domestic hot water, laundry, ice-making, process heat, etc.) in its annual publication District Energy Space.

During the latest compilation - for calendar year 2014 - IDEA members in North America reported that they added 169 customer buildings totaling 44,746,126 square feet (sq ft) of served building space to district energy service. The running total for newly-served building space for North America since 1990 is 660,174,454 sq ft.

Since 2004, IDEA has also tracked the customer growth of IDEA member district cooling system providers in the Middle East (“Beyond North America”). An additional 2,651 buildings and 75,459,748 sq ft were reported added to district cooling systems for 2014. The running total for served building space Beyond North America added since 2004 is 1,218,325,278 sq ft.
