Each year, IDEA asks all of its member systems to provide the number of buildings and their area in square feet that have been committed or recommitted to district energy service during the previous calendar year.

We report the number of buildings, gross square foot area and thermal energy services provided (heating, cooling, domestic hot water, laundry, ice-making, pool warming, etc.) that have been committed or recommitted to district energy service during the year of the edition. We also ask for overall information about your energy system, including Type of District Energy/CHP system(s); Ownership Structure, Site Overview and Total Building Area Served, System Capacity, and Annual Production.

At IDEA's Annual Conference & Trade Show, systems showcasing the most industry growth are presented with awards in the following categories:

Greatest Number of Buildings, North America
Greatest Number of Buildings, Beyond North America
Most Square Feet, North America
Most Square Feet, Beyond North America
