Whenever unconditioned space or semiheated space in a building is converted to a conditioned space, such conditioned space shall be brought into compliance with all the applicable requirements of this standard that would apply to the building envelope, heating, ventilating, air-conditioning, service water heating, power, lighting, and other systems and equipment of the space as if the building was new.
If any term, part, provision, section, paragraph, subdivision, table, chart, or referenced standard of this standard shall be held unconstitutional, invalid, or ineffective, in whole or in part, such determination shall not be deemed to invalidate any remaining term, part, provision, section, paragraph, subdivision, table, chart, or referenced standard of this standard.
The provisions of this standard shall not be deemed to nullify any provisions of local, state, or federal law. Where there is a conflict between a requirement of this standard and such other law affecting construction of the building, precedence shall be determined by the authority having jurisdiction.
The standards referenced in this standard and listed in Section 12 shall be considered part of the requirements of this standard to the prescribed extent of such reference. Where differences occur between the provision of this standard and referenced standards, the provisions of this standard shall apply. Informative references are cited to acknowledge sources and are not part of this standard. They are identified in Informative Appendix E.
The normative appendices to this standard are considered to be integral parts of the mandatory requirements of this standard, which, for reasons of convenience, are placed apart from all other normative elements.
The informative appendices to this standard and informative notes located within this standard contain additional information and are not mandatory or part of this standard.
The reference standard reproduction annexes contain material that is cited in this standard but contained in another standard. The reference standard reproduction annexes are not part of this standard but are included in the publication of this standard to facilitate use of this standard.
New buildings shall comply with either the provisions of
- Section 5, "Building Envelope"; Section 6, "Heating, Ventilating, and Air Conditioning"; Section 7, "Service Water Heating"; Section 8, "Power"; Section 9, "Lighting"; and Section 10, "Other Equipment," or
- Section 11, "Energy Cost Budget Method," or
- Appendix G. "Performance Rating Method."
When using Appendix G. the Performance Cost Index (PCI) shall be less than or equal to the Performance Cost Index Target (PCIt) when calculated in accordance with the following:
PCIt = [BBUEC + (BPF × BBREC)]/BBP
|PCI||=||Performance Cost Index calculated in accordance with Section G1.2.|
|BBUEC||=||Baseline Building Unregulated Energy Cost, the portion of the annual energy cost of a baseline building design that is due to unregulated energy use.|
|BBREC||=||Baseline Building Regulated Energy Cost, the portion of the annual energy cost of a baseline building design that is due to regulated energy use.|
|BPF||=||Building Performance Factor from Table 22.214.171.124. For building area types not listed in Table 126.96.36.199 use "All others." Where a building has multiple building area types, the required BPF shall be equal to the area-weighted average of the building area types.|
|BBP||=||Baseline Building Performance.|

|Building Area Typea||Climate Zone|
|0A and 1A||0B and 1B||2A||2B||3A||3B||3C||4A||4B||4C||5A||5B||5C||6A||6B||7||8|
a. In cases where both a general building area type and a specific building area type are listed, the specific building area type shall apply
Regulated energy cost shall be calculated by multiplying the total energy cost by the ratio of regulated energy use to total energy use for each fuel type. Unregulated energy cost shall be calculated by subtracting regulated energy cost from total energy cost.
When an addition to an existing building cannot comply by itself, trade-offs will be allowed by modification to one or more of the existing components of the existing building. Modeling of the modified components of the existing building and addition shall employ the procedures of Section 11 or Normative Appendix G; the addition shall not increase the energy consumption of the existing building plus the addition beyond the energy that would be consumed by the existing building plus the addition if the addition alone did comply.
Supplemental information necessary to verify compliance with this standard, such as calculations, worksheets, compliance forms, vendor literature, or other data, shall be made available when required by the building official.
Where reporting is required, the building official or other approved agencies shall report to the contractor their findings of conformance and nonconformance for correction.
If the nonconforming work is found not to be corrected within a predetermined time as agreed upon by the contractor, the nonconforming work shall be reported in writing to the building official and design professional. At a time agreed on by the building official or other approved agencies, a final report shall be submitted to the building official and the contractor that outlines the inspection findings and documents the correction of nonconforming work.
