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.
