From National to International: IDEA Celebrates More Than 90 Years

It was high summer in Toledo, Ohio, July 15, 1909. Horse-drawn carriages shared the streets with the occasional new Model T. Businessmen in high, starched collars and wool suits tipped their derby hats to ladies twirling parasols to shield themselves from the noonday sun. In spite of the heat, work in the unair-conditioned buildings went on, and the Ohio Electric Light Association gathered for its 14th annual convention inside the old Boody House Hotel.

The convention was held in a room off the hotel's steamy, unventilated upstairs corridor. After lunch, some of the attendees used the room for a special meeting: They wanted to talk about "the formation of an organization of central station men interested in district heating." "It was a pretty hot day to consider that subject," noted the association secretary in later chronicles.

Headed by A.C. Rogers of the Toledo Railways & Light Co., six Ohio conventioneers that day founded the National District Heating Association (NDHA). Today that organization is the International District Energy Association, comprised of more 800 district heating and cooling professionals from 18 countries.

The road from the founders' first meeting in Toledo to the IDEA of today has been a long and eventful one. Not only has the organization's membership gone global in the intervening nine decades, but its focus has expanded from "central station heating" to include district cooling and combined heat and power.

Laying the Groundwork

Although times have changed dramatically since 1909, IDEA continues as a leader in the promotion of district energy - for that it can thank its visionary founders. At their initial meeting in Toledo and in committee meetings to follow, they labored long to put their new organization on solid footing. They established NDHA's basic framework: determining membership classes; setting dues ($5 per year); preparing a preliminary constitution and bylaws; and choosing Columbus, Ohio, as the site of the first NDHA convention, held Nov. 10-11, 1909.

In the four months between NDHA's formation and that first convention, the founders faced their greatest challenge: identifying and soliciting prospective members from across the country. Nevertheless, Acting Secretary W.A. Wolls, Columbus Railway & Light Co., sent out a letter about the first NDHA convention to all known U.S. district heating businesses. As a result, 41 individuals signed up to attend. Most participants came from light, heat and power companies in Ohio, Illinois and Michigan, but many represented companies from other states, including American District Steam Co. of Lockport, N.Y.; The Paducah Light & Power Co., Paducah, Ky.; Phoenix Electric Co., Butte, Mont.; The Topeka-Edison Co., Topeka, Kan.; American Foundry & Construction Co., Pittsburgh, Pa.

At the Columbus convention, Acting President A.C. Rogers delivered an address titled "The Objects of the Association, Past, Present and Future." The preliminary constitution and bylaws were reviewed, amended and adopted. Officers were elected, with Rogers officially voted in as NDHA's first president.

Convention participants also presented papers on such topics as the Venturi meter and its use in power plants; the depreciation of underground heating mains and the method of determining same; air leakage around windows, its prevention and effect on radiation; district steam heating; and the heating and ventilating of modern buildings.

Building on Success

After Columbus, the fledgling association grew at an impressive rate. By its second annual convention, held in June 1910 in Toledo, NDHA's membership had increased nearly 200 percent. In that same year, it already began attracting the attention of energy professionals abroad: Memberships came in from Hamburg, Germany, and Paris, France. The association also broadened its focus, doing more research and publishing papers on topics never before covered in the field of district heating.

NDHA's original constitution included a statement of the organization's reason for being: "…to foster and promote the common interest of its members and to advance scientific and practical knowledge in all matters relating to Hot Water and Steam Heating, especially district Central Station Heating; also to establish cordial and beneficial relations with kindred associations and between manufacturers of Heating equipment and appliances and installers of same and the members of this Association."

More than 90 years later, IDEA remains dedicated to promoting not only "central station heating," but also district cooling and combined heat and power. And its reach is now global. Reflecting such changes in scope, the organization that began as the National District Heating Association became the International District Heating Association in 1968, then the International District Heating and Cooling Association in 1984, and finally the International District Energy Association in 1994.

Throughout its history and name changes, the organization and its conferences are built around NDHA's original goals of fostering members' common interest, advancing industry knowledge and furthering relationships among district energy professionals. It is fitting to look back on the organization's beginnings in Toledo and reflect on just how much the world has changed - yet what a vital role IDEA continues to play, now worldwide, in promoting environmental quality and energy efficiency.
