Designated as an American National Standard, the Uniform Solar, Hydronics and Geothermal Code (USHGC) is a model code developed by the
International Association of Plumbing and Mechanical Officials International is an adjective (also used as a noun) meaning "between nations".

History

Recognizing the necessity for a solar energy code to be adopted by jurisdictions as a means of regulating such systems, IAPMO passed a resolution at its 1975 annual
business conference A convention (or event), in the sense of a meeting, is a gathering of individuals who meet at an arranged place and time in order to discuss or engage in some common interest. The most common conventions are based upon industry, profession, ...
to form a technical committee for the development of such a document. After several months of work, this committee, composed of individuals representing industry,
public utility A public utility company (usually just utility) is an organization that maintains the infrastructure for a public service (often also providing a service using that infrastructure). Public utilities are subject to forms of public control and ...
companies, inspectors, plumbers, and engineers, completed the Uniform Solar Energy Code's (USEC) first edition and in September 1976 this document was adopted by IAPMO. In December 2011, the Radiant Professionals Alliance joined IAPMO and soon after work began to incorporate hydronic heating/cooling provisions into the USEC to be released in 2015 as the Uniform Solar Energy and Hydronics Code (USEHC).
