Current through Register Vol. 47, No. 3, July 24, 2024
(1)
Scope
. Rules
			 661-303.1
			 (103A) through
			 661-303.3
			 (103A) establish thermal energy efficiency standards for the design of new
			 buildings and structures or portions thereof, additions to existing buildings,
			 and renovation and remodeling of existing buildings, except for residential
			 buildings of one or two dwelling units, which are intended for human occupancy
			 and which are heated or cooled by regulating their exterior envelopes and
			 selection of their heating, ventilation, and air -conditioning systems, service
			 water heating systems and equipment for the efficient use of energy , and
			 lighting efficiency standards for buildings intended for human occupancy which
			 are lighted.
(2)
Applicability
. Rules
			 661-303.1
			 (103A) through
			 661-303.3
			 (103A) apply to design and construction of buildings which are intended for
			 human occupancy throughout the state of Iowa. Any construction of buildings or

Review by
			 architect or engineer
.
a.
Review required.
The plans and specifications for all buildings to be
			 constructed which exceed a total volume of 100,000 cubic feet of enclosed space
			 that is heated or cooled shall be reviewed by a registered architect or
			 licensed professional engineer for compliance with applicable energy efficiency
			 standards.
b.
Statement
			 of review .
A statement that a review has been accomplished and that
			 the design is in compliance with the energy efficiency standards shall be
			 signed and sealed by the responsible registered architect or licensed
			 professional engineer . This statement shall be filed with the commissioner or
			 a local building official on a form approved by the commissioner prior to
			 construction or before obtaining any local permits. The statement shall be
			 filed with the commissioner for any project which is subject to plan review by
			 the building code bureau.
c.
Additional buildings.
If the plans and specifications
			 relating to energy efficiency for a specific structure have been approved,
			 additional buildings may be constructed from those same plans and
			 specifications without need of further approval if construction begins within
			 five years of the date of approval. Alterations of a structure which has been
			 previously approved shall not require a review because of these changes,
			 provided the basic structure remains unchanged and no additional energy is
			 required for heating, cooling or lighting.
d.
Changes to approved
			 plans.
Prior to the completion of construction, no changes shall be
			 made to any approved plan or specifications which increase the amount of energy
			 used for heating, cooling, or lighting, unless the changes are approved by the
			 responsible registered architect or licensed professional engineer in writing
			 and notice has been filed with the commissioner or a local building official.
			 The commissioner or a local building official shall be notified of any change
			 which is anticipated to decrease the amount of energy used. Notification
			 pursuant to this paragraph shall be to the commissioner for any project which
			 is subject to plan review by the building code bureau.
