If structural calculations are used to determine adequacy, the mullion deflection is limited to L/175 of the length of the long edge of the glass being supported. This requirement applies whether the entire window unitincluding frame, sash and glazingis being replaced, or just the sash and glazing. 0000028405 00000 n The ability to trade off a more efficient mechanical system for other components of the building, however, is not included in the list of those permitted in the 2018 IECC. Skylights and sloped glazing are also subject to snow load and dead load. Beginning with the 2012 International Codes, the energy conservation provisions of Chapter 11 of the IRC are an exact duplicate of the provisions of the IECC for the same building. 41). Because many belt terminals slide onto the anchor from above and extend 4 or 5 inches below the anchor when attached, obstructions shall not be allowed within this distance above or below the anchor head. 2015 International Building Code (IBC) with Washington State Amendments.

The 2018 IRC glazing requirements remain mostly unchanged, but for modifications addressing glazing adjacent to doors, in guards and railings, and adjacent to the bottom stair landing. If testing is the method used to determine structural adequacy of mullions, it is to be done in accordance with AAMA 450-10, Voluntary Performance Rating Method for Mulled Fenestration Assemblies. The pass/fail criterion for windows, skylights and sliding glass doors remains at 0.3 cfm per square foot. Sentences 9.8.8.1.

Having a 24-36-inch buffer under the bottom portion of the window makes it much less likely that small children will inadvertently put themselves in danger. My opinion is baths are too dark without some daylight. Specifically, ERI scores were increased from 55 to 61 in Climate Zone 5 and from 51 to 57 in Climate Zone 3. In most of the central U.S., the design wind speeds were reduced from the 2010 edition of ASCE 7 to the 2016 edition. endstream endobj startxref You are using an out of date browser. Requirements for energy performance in both residential and commercial buildings are spelled out in the 2018 IECC. This reliance on the International Codes has now spread to other countries, including Georgia (Eastern Europe), Mexico, Columbia and Honduras. 5. The method for determining the ERI is now required to be in accordance with the RESNET/ICC Standard 301, which covers how to calculate the ERI score, compliance software tool certification and provides sources for input values not specified in the 2018 IECC.

Tables R301.2(2) and R301.2(3) of the 2018 IRC give the design wind loads for glazed openings based on the design wind speed of the specific location where construction is to take place, the mean height of the building and its exposure to wind. ), (7) Stationary panels up to 5 feet in width may be cleaned by standing on a sill or ledge (See Figure 1 for width and slope restrictions) while supported by anchors on each side of the panels if access is provided via an openable panel adjacent to the stationary panel.
