			 requirements.
Compliance with Section C407 also requires compliance with
			 those sections shown in Table C407.2.
The building permit application for projects utilizing this
				method shall include in one submittal all building and mechanical drawings and
				all information necessary to verify that the building envelope and mechanical
				design for the project corresponds with the annual energy analysis. If credit
				is proposed to be taken for lighting energy savings, then an electrical permit
				application shall also be submitted and approved prior to the issuance of the
				building permit. If credit is proposed to be taken for energy savings from
				other components, then the corresponding permit application (e.g., plumbing,
				boiler, etc.) shall also be submitted and approved prior to the building permit
				application. Otherwise, components of the project that would not be approved as
				part of a building permit application shall be modeled in the baseline in
				accordance with ANSI/ASHRAE/IESNA 90.1 Appendix G and in the proposed model in
				accordance with the requirements of the Washington State Energy Code.
