New buildings shall comply with at least one of the following sections:
Buildings shall be of the following types to use this compliance method:
The building service water-heating system shall have one or more of the following that are sized to provide not less than 60% of the building's annual hot water requirements, or sized to provide 100% of the building's annual hot water requirements if the building shall otherwise comply with Section 22.214.171.124:
Air infiltration shall be verified by whole-building pressurization testing conducted in accordance with ASTM E779 or ASTM E1827 by an independent third party. The measured air-leakage rate of the building envelope shall not exceed 0.25 cfm/ft2 under a pressure differential of 0.3 inches water column (75 Pa), with the calculated surface area being the sum of the above- and below-grade building envelope. A report that includes the tested surface area, floor area, air by volume, stories above grade, and leakage rates shall be submitted to the building owner.
For buildings having over 250,000 square feet of conditioned floor area, air leakage testing need not be conducted on the whole building where testing is conducted on representative above-grade sections of the building. Tested areas shall total not less than 25% of the conditioned floor area and shall be tested in accordance with this section.
