OAR 330-135-0035: Eligible Green Energy Technology Costs

(1) For photovoltaic systems, eligible costs include the photovoltaic modules, racking system, mounting structure and hardware, modifications to the building structure specifically to accommodate the solar energy system, associated electrical equipment, battery storage equipment and technology, metering, labor and system commissioning. Specific elements that do not qualify as eligible costs include, but are not limited to, the following: (a) Costs for auxiliary distribution systems such as chargers in electric vehicle charging stations. (b) Costs for reroofing. (2) For building integrated photovoltaic (BIPV) systems, eligible costs include the difference between the costs for the BIPV components and the costs of the conventional building components that are modified or replaced to accommodate the installation of the BIPV system components. (3) For solar water heating and solar pool heating systems, eligible costs include the solar collectors, mounting structure and hardware, associated plumbing and controls, metering, labor, and system commissioning. Costs for backup systems that use conventional energy sources do not qualify. (4) For active solar space heating systems, eligible costs include the solar collectors, mounting structure and hardware, associated plumbing and controls, metering, labor, and system commissioning. Costs for heat distribution systems, such as ductwork or radiant floors, or costs for backup systems that use conventional energy sources, do not qualify. (5) For passive solar systems and daylighting systems, eligible costs include materials and labor costs that can be directly and exclusively attributed to the passive solar and daylighting system, the cost for modeling the building energy performance, and commissioning. (a) For passive solar systems eligible costs may include, but not be limited to, added thermal mass, incremental insulation costs above energy code levels, and shading controls. (b) For daylighting systems, eligible costs may include, but not be limited to, automatic controls, light shelves, overhangs, automated louvers and blinds and related controls, skylights in spaces where automatic controls are present, and the portion of windows higher than 7 feet above the floor. Eligible costs include those associated with daylighting system elements that represent more than the minimum energy code requirement. Costs for energy code-required daylighting system elements are not eligible. (6) For geothermal electricity generation, eligible costs include the cost of supply and disposal pipelines, turbine generators, controls, transformers, battery storage equipment and technology, metering, labor, and balance of plant. (7) For geothermal energy use in building systems, eligible costs include the cost of supply and disposal pipelines, pumps, heat exchangers, controls, the cost for modeling the building energy performance, metering, and labor. (8) Costs for permanent educational displays located in or on the building that explain the green energy technology incorporated in the project are allowed.
