District Energy Space

Showcasing Industry Growth

District Energy Space is IDEA's annual compilation of the number of buildings and their area in square feet that have been committed or recommitted to district energy service by IDEA member systems during the previous calendar year. In conjunction with the annual publication, IDEA acknowledges District Energy Systems contributing the highest growth in North America and Beyond North America with annual District Energy Space awards. 


District Energy Space 2021 - Now Available

The International District Energy Association (IDEA) has released its annual report, District Energy Space, detailing the growth in district energy for 2021.  This year’s results, which showed a nearly 5% increase in the buildings committed, builds upon a more than decade-long trend of increasing adoption of district energy to reliably and efficiently deliver heating and cooling to buildings both here in the U.S. and around the globe.

The report, which has been an annual tradition for IDEA since 1990, is the result of voluntary reporting by its member system operators who share information about both buildings newly committed and those that have extended a contract with a duration of 10 years or more. The report also details building names, types of use (i.e. commercial office space, hotel, etc.), location, services (heating, cooling, hot water) and square footage served.  The report also provides summary insights on industry growth in North America and Beyond North America.

We have revealed the 2021 District Energy Space Gold, Silver and Bronze winners for Most Total Buildings Added and Most Square Footage added in North America and Beyond North America categories - find out who won by clicking below.
