Current through Register Vol. 47, No. 3, July 24, 2024
A commercial building construction project shall be approved as
				sustainably designed if it meets the following applicable requirements:
(1) If approval as a sustainably designed
			 project is being sought in order to qualify for a tax credit or tax refund, the
			 project shall be approved as sustainably designed if the building receives
			 certification from the United States Green Building Council at the gold level
			 or better in the Leadership in Energy and Environmental Design (LEED) Green
			 Building Rating System, version 3.0; and if the building complies with the
			 requirements of ASHRAE 90.1-2007, Energy Standard for Buildings Except Low-Rise
			 Residential Buildings, published by the American Society of Heating,
			 Refrigerating and Air-Conditioning Engineers, 1791 Tullie Circle, NE, Atlanta,
			 GA 30329.
Exception: If a good-faith effort has been made to obtain
				certification at the gold level or above in the LEED Green Building Rating
				System, version 3.0, and certification at the gold level has not been obtained,
				but certification at the silver level has been obtained, application may
				nonetheless be made to the building code commissioner for approval as a
				sustainably designed project. The commissioner may approve the project as
				sustainably designed provided that the building is fully in compliance with
				ASHRAE 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential
				Buildings, published by the American Society of Heating, Refrigerating and
				Air-Conditioning Engineers, 1791 Tullie Circle, NE, Atlanta, GA 30329, and
				demonstration is made to the satisfaction of the building code commissioner
				that a good-faith effort to achieve certification at the gold level was made
				and that the project demonstrates an emphasis on energy conservation.
(2) If approval as a sustainably
			 designed project is being sought other than for the purpose of obtaining a tax
			 credit or tax refund, the project shall be approved as sustainably designed if
			 the building receives certification from the United States Green Building
			 Council at the silver level or better in the LEED Green Building Rating System,
			 version 3.0; and if the building complies with the requirements of ASHRAE
			 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings,
			 published by the American Society of Heating, Refrigerating and
			 Air-Conditioning Engineers, 1791 Tullie Circle, NE, Atlanta, GA 30329.
Exception: If a good-faith effort has been made to obtain
				certification at the silver level or above in the LEED Green Building Rating
				System, version 3.0, and certification at the silver level or above has not
				been obtained, but certification has been obtained, application may nonetheless
				be made to the building code commissioner for approval as a sustainably
				designed project. The commissioner may approve the project as sustainably
				designed provided that the building is fully in compliance with ASHRAE
				90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings,
				published by the American Society of Heating, Refrigerating and
				Air-Conditioning Engineers, 1791 Tullie Circle, NE, Atlanta, GA 30329, and
				demonstration is made to the satisfaction of the building code commissioner
				that a good-faith effort to achieve certification at the silver level was made
				and that the project demonstrates an emphasis on energy conservation.
(3) If the project includes only
			 the following commercial structures, the project shall be approved as
			 sustainably designed if it satisfies all of the mandatory criteria of the Iowa
			 green streets criteria:
a. Day care
			 centers.
b. Vocational
			 rehabilitation centers.
c.
			 Community centers.
d. Senior
			 centers.
Exception: Application may be made to the building code
				commissioner to accept satisfaction of all of the mandatory criteria of the
				Iowa green streets criteria, published by the Iowa department of economic
				development, community development division, as the basis for approval of other
				commercial projects as sustainably designed. Such submission should be limited
				to smaller commercial projects, and approval as a sustainably designed project
				is at the discretion of the building code commissioner, who shall award such
				approval only if the building code commissioner is convinced that the Iowa
				green streets criteria are applicable to the project. Written approval for use
				of the Iowa green streets criteria pursuant to this exception shall be sought
				and obtained prior to submission of an application for approval as a
				sustainably designed project.
