During review of the above noted application, it was found that the following information,
corrections, or clarifications are needed. Please redline plans or submit two (2) sets of revised
plans/documents (affected sheets only) with a written response to each of the items below to a
Permit Coordinator.
1) Please complete the enclose Energy Form Handout. Also, based on form show size and location
of proposed whole house fan on the plans.
2) Note garage/dwelling separation on plans for wall between new garage and existing house.
Minimum 1/z" sheetrock required on garage side of wall and 5/8" type X on the ceiling when
there is habitable space above.
3) R403.1.3 requires all vertical rebar to have a standard hook. Revise all foundation details to
. reflect.
4) Provide East elevation view.
5) Provide section detail through the garage/roof deck to show how 2% minimum slope will be
achieved and show direction of all roof deck drainage on the roof framing plan.
6) Provide construction/connection detail for roof guardrail.
7) In the gravity calculations I was unable to locate a calculation for the proposed 4x10 garage door
header with 18'+ span. Please provide calculation for this header.
8) Per the lateral calculations the shearwall on the left side of the garage is required to be 5' and
plans are showing 4'-4 %2". Please revise plans to match calculations or provide revised
calculations.
9) Engineer of Record please provide shearwall nailing schedule and clarify holdown to use for
TDI which are called out in the calculations and add this information to the plans. Currently no
holdowns are shown on the plans.

Washington State Energy & Ventilation Codes
Residential Compliance Worksheets
Prescriptive Approach
CODES: Edmonds Community Development Code Chapters 19.30 and 19.35
Washington State Energy Code (Current Edition)
Washington State Ventilation & Indoor Air Quality Code (Current Edition)
The purpose of the State energy code is to provide minimum standards for new or remodeled construction to
achieve efficient use and conservation of energy. The code allows flexibility to permit the use of innovative
approaches and techniques. This handout however only provides the basic minimum codes for prescriptive
compliance.
This handout describes the basic prescriptive approach for energy code compliance that is the easiest way to
determine or show code compliance. It is a straight takeoff and comparison of total window (glazing) and door
opening area versus the heated floor space. The percentage of glazing shown on the enclosed charts determines
the U -value of all windows and doors, and the R -value for wall, floor, slab and ceiling insulation. This handout
is intended to provide minimum prescriptive compliance and it is not intended as a substitute for the entire State
Energy Code.
Also included in this packet is a Ventilation and Indoor Air Quality Worksheet. Tighter construction and
insulation standards have introduced a vast amount of chemicals and other pollutants into dwellings. The
process of natural ventilation has also been greatly reduced due to the required sealing of sheathing at walls and
floor levels. The State Ventilation and Indoor Air Quality Code has been created as a means for bringing in
fresh outdoor air, and exhausting the interior stale air. The code allows either a manual portal system or a
mechanical system that runs unmonitored on a timer to convey the air.
Forms and additional information about the State Energy and Ventilation Codes can be found on the WEB at
www. energ_y.wsu. edu.

Residential Prescriptive (Chapter 6) Options for All Heat'Sources
Instructions:
Carefully review the requirements for each of the options below. Choose an option that best suits your dwelling design. Glazing percentage
typically determines which option to choose. Your building must match the selected option requirements without exceptions or substitutions.
Disregard components or equipment that does not apply to your project. Your permit will be processed more efficiently if you provide all of the
requested information. Department staff can help you with general questions about this form. Proposed designs which cannot meet the specific
requirements of a listed option above may calculate compliance by Chapters 4 or 5 of the 2003 Washington State Energy Code. Forms can be found
on the WEB at WWW.ENERGY.WSU.EDU

*Reference Case
° Nominal R -values are for wood frame assemblies only or assemblies built in accordance with Section 601.1.
Minimum requirements for each option listed. For example, if a proposed design has a glazing ratio to the conditioned floor area of 13%, it shall
comply with all of the requirements of the 15% glazing option (or higher). Proposed designs which cannot meet the specific requirements of a
listed option above may calculate compliance by Chapters 4 or 5 of this Code.
2 Requirement applies to all ceilings except single rafter or joist vaulted ceilings. `Adv' denotes advanced Framed Ceiling.
3 Requirement applies only to single rafter or joist vaulted ceilings.
a Below grade walls shall be insulated wither on the exterior to a minimum level of R-10, or on the interior to the same level as walls above grade.
Exterior insulation installed on below grade walls shall be a water resistant material, manufactured for its intended use, and installed according to
the manufacturer's specifications. See Section 602.2.
5 Floors over crawl spaces or exposed ambient air conditions.
6 Required slab perimeter insulation shall be a water resistant material, manufactured for its intended use, and installed according to manufacturer's
specifications. See Section 602.4.
7 Int. denotes standard framing 16 inches on center with headers insulated with a minimum of R-5 insulation.
s This wall insulation requirement denotes R-19 wall cavity insulation plus R-5 foam sheathing.
9 Doors, including all fire doors, shall be assigned default U -factors from Table 10-6C.
10 Where a maximum glazing area is listed, the total glazing area (combined vertical plus overhead) as a percent of gross conditioned floor area shall
be less than or equal to that value. Overhead glazing with U -factor of U=0.40 or less is not included in glazing limitations.
Overhead glazing shall have U -factors determined in accordance with NFRC 100 or as specified in Section 502.1.5.
12 Log and solid timber walls with a minimum average thickness of 3.5" are exempt from this insulation requirement.
This project will take advantage of the following exceptions to the prescriptive option:
