11.4.5 Exceptional Calculation Methods
Where no simulation program is available that adequately models a design, material, or device, the authority having jurisdiction may approve an exceptional calculation method to be used to demonstrate compliance with Section 11. Applications for approval of an exceptional method to include theoretical and empirical information verifying the method's accuracy shall include documentation to demonstrate that the exceptional calculation method and results
- make no change in any input parameter values specified by this standard and the adopting authority,
- provide input and output documentation that facilitates the enforcement agency's review and meets the formatting and content required by the adopting authority, and
- are supported with instructions for using the method to demonstrate that the energy cost budget and design energy cost required by Section 11 are met.
