OAR 330-135-0030: Green Energy Technology Performance Requirements

(1) Solar electric (photovoltaic), solar water heating, solar pool heating, and active solar space heating systems are to be installed in locations that have a total solar resource fraction (TSRF) of 75 percent or greater. (2) Photovoltaic and geothermal electric systems must be separately metered to record electricity production. (3) Geothermal systems that directly supply heat to the building system(s), passive solar thermal systems, daylighting systems or any combination thereof must jointly reduce the building’s energy use by 10 percent or more, as demonstrated with whole building energy modeling prepared under the direction of a licensed professional engineer. (a) For local or special government bodies, the baseline and proposed buildings must be modeled according to the requirements of the 2019 Energy Code. (b) For state government bodies, the baseline and proposed buildings must be modeled according to the requirements of the Proposed Building as defined in the State Energy Efficient Design (SEED) Guidelines. (c) The model for the proposed geothermal systems supplying heat to the building system(s), passive solar thermal systems, daylighting systems or any combination thereof must only include differences that are directly attributable to the geothermal heating system, passive solar thermal systems or daylighting systems. Lighting, HVAC and other equipment efficiencies, etc., must be identical between the baseline and proposed models. (d) The system(s) must be commissioned by a third-party commissioning agent. (4) Purchase of renewable energy certificates does not constitute compliance with the requirements of ORS 279C.527 through 279C.528 and Oregon Laws 2019, chapter 160 (HB 2496).
