(1) Except for alternative fuel vehicles or related equipment, in order to carry out ORS 469.160 to 469.180, the State Department of Energy shall develop performance assumptions and prescriptive measures to determine the eligibility and tax credit amount for alternative energy devices constructed or installed in a dwelling.
(2) The department shall use the performance assumptions and prescriptive measures to develop information for the Department of Revenue to use to allow taxpayers to determine their eligibility and tax credit amount. The State Department of Energy may review this information on an annual basis to take into consideration new technology and performance assumption accuracy.
(3) For the purpose of determining the first year energy yield of an alternative energy device, the department shall use the following assumptions and test standards:
(a) Solar Rating and Certification Corporation standard SRCC 100, 200, American Society of Heating, Refrigerating and Air-Conditioning Engineers 93-77, or the American Refrigeration Institute standard 325-85 test at 50 degrees entering water temperature, as appropriate. The testing requirements under this paragraph shall not apply to an owner-built alternative energy device.
(b) For an alternative energy device used as a source for domestic water heating energy, a hot water use of 75 gallons per day at 120 degrees Fahrenheit. The load of 75 gallons per day at 120 degrees Fahrenheit shall be achieved by including conservation measures in the construction or installation of the alternative energy device.
(c) For an alternative energy device used as a source for space heating or cooling, the heating or cooling energy load as determined by a heat loss or gain calculation performed in accordance with the methods established by the American Society of Heating, Refrigerating and Air-Conditioning Engineers. Except for an owner-built or site-built system, an alternative energy device used as a source for domestic hot water heating must meet the SRCC OG 300 systems test or comply with comparable requirements as determined by the department.
(d) For an alternative energy device used as a source for electrical energy, the first year energy yield shall be based upon the electrical energy load of the dwelling as determined according to the procedure established by the department.
(e) For an alternative energy device used as a source for swimming pool, spa or hot tub heating, the first year energy yield shall be based on the heating load of the swimming pool, spa or hot tub as determined according to the procedure established by the department.
