Uniform Solar Energy and Hydronics Code
 |
The Uniform Solar Energy and Hydronics Code (USEHC) is a model code developed by the International Association of Plumbing and Mechanical Officials (IAPMO) to govern the installation and inspection of solar energy and hydronic heating/cooling systems as a means of promoting the public's health, safety and welfare.
History
The advantages of a Uniform Solar Energy and Hydronics Code [1], acceptable in various jurisdictions, had long been recognized, prompting IAPMO to pass a resolution at its 1975 annual business conference that directed the president to form a committee to develop a basic solar energy document.
After months of concerted endeavor, this committee, composed of representatives from industry and public utility companies, inspectors, plumbers and engineers, successfully completed the first edition of the Uniform Solar Energy Code (USEC), which was officially adopted by IAPMO in September 1976.
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.
