In the IECC, Section C103.1 Construction Documents, General, the wording states that construction documentation and other supporting data shall be submitted in one or more sets with each application for a permit.
#ASHRAE 90.1 U VALUES CODE#
The thermal envelop of buildings shall comply with Sections C402.5.1 through C402.5.8, or the building thermal envelope shall be tested in accordance with ASTM E 779 at a pressure differential of 0.3 inch water gauge (75Pa) or an equivalent method approved by the code official and deemed to comply with the provisions of this section when the tested air leakage rate of the building thermal envelope is not greater than 0.4 cfm/ft2 (0.2 L/s.m2).The commercial energy code requires that a registered professional submit compliance documentation (construction documents and compliance verification). Light well depth = Measure vertically from the underside of the lowest point of the skylight glazing to the ceiling plane under the skylight.

WF = Area weighted average well factor, where well factor is 0.9 if light well depth is less than 2 feet (610 mm), or 0.7 if light well depth is 2 feet (610 mm) or greater. Skylight VT = Area weighted average visible transmittance of skylights. Skylight area = Total fenestration area of skylights. In an enclosed space greater than 2,500 square feet (232 m2) in floor area, directly under a roof with not less than 75 percent of the ceiling area with a ceiling height greater than 15 feet (4572 mm), and used as an office, lobby, atrium, concourse, corridor, storage space, gymnasium/exercise center, convention center, automotive service area, space where manufacturing occurs, non-refrigerated warehouse, retail store, distribution/sorting area, transportation depot or workshop, the total daylight zone under skylights shall be not less than half the floor area and shall provide one of the following:Ī minimum skylight area to daylight zone under skylights of not less than 3 percent where all skylights have a VT of at least 0.40 as determined in accordance with Section C303.1.3.Ī minimum skylight effective aperture of at least 1 percent, determined in accordance with Equation 4-4. The skylight area shall not be greater than 3 percent of the gross roof area. Additions that result in a total building vertical glass area exceeding that specified in Section C402.4.1.1 shall comply with Section C407. Additions with vertical fenestration that result in a total building fenestration area greater than Section C402.4.1 or additions that exceed the fenestration area greater than Section C402.4.1 shall comply with Section C402.4.1.1 for the addition only. Vertical Fenestration: New vertical fenestration area that results in a total building fenestration area less than or equal to that specified in Section C402.4.1 shall comply with Section C402.4. Daylight responsive controls shall comply with this section and Section C405.2.3.1. Roof solar reflectance and thermal emittance shall comply with Section C402.3įenestration in building envelope assemblies shall comply with Section C402.4Īir leakage of building envelope assemblies shall comply with Section C402.5įenestration shall comply with Sections C402.4 through C402.4.4 and Table C402.4. The opaque portion of the building thermal envelope shall comply with the specific insulation requirements of Section C402.2 and the thermal requirements of either the R-value –based method of section C 402.1.3 the U-, C-, F-Factor-based method of Section C402.1.4 or the component performance alternative of Section C402.1.5 Where some or all of an existing fenestration unit is replaced with a new fenestration product, including slash and glazing, the replacement fenestration unit shall meet the applicable requirements for U-factor and SHGC in Table C402.4.īuilding thermal envelope assemblies for building that are intended to comply with the code on a perspective basis, in accordance with the compliance path described in Item 2 of Section C401.2, shall comply with the following: Application to replacement fenestration products
