Subject: Westgate Village (Energy Code Revisions)
Permit: 2017-01538
Per your request, Beck & Associates has completed a review of the submitted revisions for this permit application for conformance with the 2015 International Building Code (IBC), as
adopted and amended by the State of Washington (WSA) and the City of Edmonds (ECC).
Our review of the plans and calculations indicates that corrections are necessary prior to permit issuance. The applicant should address the following comments in itemized letter format
in addition to making corrections & revisions to the drawings. Corrections and revisions to the drawing should be clouded so that they are clearly identifiable.
Scope of Review: As requested, the scope of our review is limited to the revised energy code analysis (G015 and G016) and revised assemblies (clouded items only on G003) that reflect
changes made as a result of the revised energy analysis.
General
Originally approved drawing sheet G016 includes information related to Air Barrier (C402.5.1.1 through C402.5.1.2); Additional Energy Efficiency Package Options chosen (C406 – Reduced
Lighting Power, Reduced Air Infiltration); Commissioning (C408); and Energy Metering and Energy Consumption Management (C409). This information is not included in the revised drawings.
Update the revised drawings to include the previously approved information that was located on sheet G016.
Reference G003 - Assemblies
Originally approved drawings (G003) include information which is now missing on the revised drawing sheet. This information needs to be included on the revised drawings:
Information related to Fire Wall Marking and Identification
GA File No. WP 3380 (for construction of Wall Type “13”)
GA File No. WP 3660 (for construction of Wall Type “2”)
Reference Wall Type ‘21’ on G003. The detail specifies “(2) layers 5/8” Type X GWB @ each side of stud @ 2 hr application” OR “(1) layer each side @ stud ¾” proprietary struct cement
panel + (1) layer 5/8” Type X GWB @ 3 hour”. Neither of these specifications is consistent with the referenced listed, tested assembly WP2931. Update the detail to exactly match the
requirements of WP2931.
Reference G015 – Energy Code
Reference the Wood Stud Wall Assembly Calculations located at the bottom right hand corner of the drawing sheet.
The architectural plans do not specify (2) stud corners (intermediate framing). Revise either the energy analysis or the architectural drawing accordingly.
Per architectural and structural plans, headers do not occur in the floor system. Neither are insulated headers specified. Revise either the energy analysis or the architectural drawing
accordingly.
Please contact me should you have any questions.
