Solar Thermal Standard Consensus Committee (IS-STSC)

Development and maintenance activities for ICC's family of solar thermal consensus standards is assigned to the Solar Thermal Standard Consensus Committee (IS-STSC).  The committee is convened as required for maintenance of existing standards and to develop new standards as needed.  It operates under ICC's ANSI-approved standard development procedures.

The IS-STSC is currently ACTIVE and was convened to develop a proposed new standard, BSR/ICC 903/SRCC 500 for solar hot water storage tanks.  ICC filed PINS with ANSI to develop the new standard in late 2020, and they appeared in Vol. 51, No. 52 edition of ANSI Standards Action on December 25, 2020. Appointments were made to the IS-STSC by the ICC Board of Directors in the Fall of 2021 and the first committee meeting was held in January, 2022.
