Alarm clearances should comply with Section R314.3 Item 4 and Section 314.3.1. Response:See general notes number 1 and 8. • The roof details should comply with the ventilation requirements of IRC Section R806 and WSEC Section R402.2.3. Include a calculation for the minimum required ventilation area in the drawings. The vents should be equally distributed between the roof eaves and ridge, and around the building perimeter. Response:See roof plan for vent locations and calculations. • The attic spaces should be provided with access openings per IRC Section R807. V Response:See access hatch outside bathroom 8. • Insulation should be specified for all exterior walls, floors, slab-on-grade, and ceiling/roof cavities per WSEC Table 402.1.1. Response:See roof plan and revised floor plan for insulation specifications. • The project includes replacement of the existing windows and exterior doors. The required thermal s ratings for each type of vertical fenestration should be specified. See WSEC Table R402.1.1. Response:See revised plans for new windows vertical fenestrations • The project involves increasing the conditioned space at the upper floor. Energy credits are required per WSEC Section R406. The required number of credits should be normalized per Table R406.2. A schedule of the selected credits should be included in the drawings. The performance requirements for the selected credits should be specified. Response:See energy credits in revised plans • The project requires a whole house ventilation system per IRC Section R303.4. The drawings should show the location(s)of the system component(s),and specify the performance requirements per Section M1505.4.1. The system should be located in a central area that is open to and has unobstructed air flow with the majority of the habitable space. Alternatively, if the system is not centrally located, the system should provide ducting to each room of the house per Section M1505.4.1.1, and the drawings should specify a requirement for testing to verify air flow rates per Section M1505.4.1.6. The system should not have a sound rating exceeding 1.0 sones. Response:See revised plans for ventilation for the new additional space. • The bathrooms and kitchen should specify exhaust fans including the minimum required performance rates per IRC Table M1505.4.4(1). /Response: See plans for bathroom and kitchen exhaust fan. 2\ 5
