Current through Register Vol. 24-14, July 15, 2024
R405.3
Documentation.
Documentation of the software used for the
			 performance design and the parameters for the building shall be in accordance
			 with Sections R405.3.1 through R405.3.2.2.
R405.3.1
Compliance software
			 tools.
Documentation verifying that the methods and accuracy of the
			 compliance software tools conform to the provisions of this section shall be
			 provided to the
code official
.
R405.3.2
Compliance report.
Compliance software tools shall generate a report that documents that the
proposed design
complies with Section R405.2.
A compliance report on the
proposed design
shall be submitted with the application for the building permit. Upon
				completion of the building, a confirmed compliance report based upon the
				confirmed condition of the building shall be submitted to the
code
				official
before a certificate of occupancy is issued.
Compliance reports shall include information in accordance with
				Sections R405.3.2.1 and R405.3.2.2.
R405.3.2.1
Compliance report for permit
			 application.
A compliance report submitted with the application for
			 building permit shall include all of the following:
1. Building street address, or other building
			 site identification.
2. The name,
			 organization, and contact information of the individual performing the analysis
			 and generating the compliance report.
3. The name and version of the compliance
			 software tool.
4. Documentation of
			 all inputs entered into the software used to produce the results for the
			 reference design and/or the rated home.
5. A certificate indicating that the
proposed design
complied with Section R405.2. The certificate
			 shall document the building components' energy specifications that are included
			 in the calculation including: Component-level insulation
R
-values or
U
-factors; duct system and
			 building envelope air leakage testing assumptions; and the type and rated
			 efficiencies of proposed heating, cooling, mechanical ventilation, and service
			 water-heating equipment to be installed. If on-site renewable energy systems
			 will be installed, the certificate shall report the type and production size of
			 the proposed system. Additional documentation reporting estimated annual energy
			 production shall be provided.
6.
			 When a site-specific report is not generated, the
proposed
			 design
shall be based on the worst-case orientation and configuration
			 of the rated home.
R405.3.2.2
Compliance report for
			 certificate of occupancy.
A compliance report submitted for obtaining
			 the certificate of occupancy shall include all of the following:
1. Building street address, or other building
			 site identification.
2. Declaration
			 of the total building performance path on the title page of the energy report
			 and the title page of the building plans.
3. A statement bearing the name of the
			 individual performing the analysis and generating the report, along with their
			 organization and contact information, indicating that the as-build building
			 complies with Section R405.2.
4.
			 The name and version of the compliance software tool.
5. A site-specific energy analysis report
			 that is in compliance with Section R405.2.
6. A final confirmed certificate indicating
			 compliance based on inspection, and a statement indicating that the confirmed
			 rated design of the built home complies with Section R405.2. The certificate
			 shall report the energy features that were confirmed to be in the home,
			 including component level insulation
R
-values or
U
-factors; results from any required duct system and building
			 envelope air leakage testing; and the type and rated efficiencies of the
			 heating, cooling, mechanical ventilation, and service water-heating equipment
			 installed.
7. Where on-site
			 renewable energy systems have been installed, the certificate shall report the
			 type and production size of the installed system. Additional documentation
			 reporting estimated annual energy production shall be provided.
