CG Project Number: 20484
Dear Mr. Akau,
Itemized below is our response to the review comments dated February 23`d, 2021 for the above
referenced project. Our response appears in bold.
General:
1. Per Section R406, the additional energy efficiency requirements require, that the drawings
included with the building permit application, shall identify which options have been selected,
and the point value of each option, regardless of whether separate mechanical, plumbing,
electrical, or other permits are utilized for the project. Please make corrections and provide this
information on your set of plans.
Refer to the energy calculation worksheet on sheet A0.1 of the architectural drawings. The
option selected is Option 5a (0.5 credits) for Efficient Water Heating 5a. The water heating
system is a 0.95 Energy Star rated tankless water heater (Model No. Navien CR-180A)
shown on sheet A1.2. The addition is less than 500 square feet and therefore only requires
0.5 credits per the energy calculation worksheet.
2. After review of the Energy calculation documents provided. It is apparent that the WSEC credit
chosen is not accurately demonstrated in the calculation packet. Please review/correct the Energy
calculations. This is to be demonstrated on the plans as well as the packet.
Refer to the revised architectural plans with the energy calculation worksheet.
3. Provide cross sections on your plans, to demonstrate that the building thermal envelope shall
meet the requirements of Sections R402.1.1 through R402.1.5 of Washington State Energy Code.
This information is shown on the wall section 2 on A3.1
Sheet A1.2:
4. Provide a floor plan of the plumbing fixtures in the new proposed bathroom.
