Provide written responses to each comment and where changes can be found on the plans. Please resubmit to Theresa Umbaugh, Permit Coordinator. Applicable previous comments and worksheets referenced below are attached for your convenience. Previous correction 1 (references correction 3 of 1015/07 comments): a. Complete the enclosed Energy Worksheets for the kitchen addition and note all insulation R -values and window U -values on the plans. If the addition cannot meet prescriptive energy code requirements, construction must be revised to accommodate the minimum insulation values, or energy calculations using the Component Performance approach (WSEC Chapter 5) must be provided calculation forms and instructions can be found on the web at www.energy.wsu.edu). For example, 2x6 floor joists cannot hold R-30 batt insulation (minimum would be 2x10), however you may see if rigid insulation will meet this requirement. This will be same issue for 2x4 walls and 2x6 floor joists, and may also be an issue for window and skylight glazing. If any item of the prescriptive Table 6-1 cannot be met, energy calculations using the Component Performance approach will be required.. b. Show the kitchen addition on the site plan and note.the floor area. .2. Special inspection will be required for the installation of epoxy anchors that the structural engineer is requiring on the structural pians.

Regarding your request to defer response to previous item 3, 4 & 5 in Building Division plan review comments dated 10/5/2007, as explained in City letter dated 9124/2007, if you were unable to obtain City or County permit records for the kitchen addition, then the addition must be included with this permit. The Stop Work order will not be lifted until all issues are resolved and permit(s) issued- The design (structural and architectural) of the kitchen and remodel of the living/dining/den/entry area must be reviewed at the same time. For clarification to your statement in your response letter (dated January 10, 2008) regarding item 3g, the area of the kitchen addition shown the site plan approved for the roof cover (permit # 1998-0031) was labeled on the plan submitted to the City as "existing house", and in no way gave approval for the kitchen addition. 2.

As discussed at our meeting, please dimension the framing plan for the north half of the roof: Dimension the spans of all beams/headers and rafters, as well as the exterior walls (perimeter) of the building- Without this information the loads cannot be verified_ Also, note the scale of the plan such as V;'= l foot or 3/16" = 1 foot (currently it does not appear to be a recognized scale)_ This is required in the City's Addition/Remodel handout previously provided to you- 3- Kitchen addition (see attached handout): a. As noted in the Building Official's letter to you dated September 24, 2007, provide complete plans of the kitchen addition, including foundation, floor framing, elevation views, (roof framing already provided), and cross reference the building sections that you have drawn on the framing plans. Examples of plans and details can be found in the enclosed handout. b- Based on the section submitted for the Kitchen West Wall Load Path, the roof framing is non -conventional construction and does not meet the conventional provisions of IRC 802-3. Flans and structural calculations must be stamped and Osigned by a State licensed Professional Engineer. Complete the enclosed Energy Worksheets for the kitchen addition and note all insulation R -values and window U -values on the plans_ If the addition cannot meet current energy code requirements, construction must be revised to accommodate the minimum insulation values, or energy calculations using the Component Performance approach (WSEC Chapter 5) must be provided- For example, 2x6 floor joists cannot hold R-30 batt insulation (minimum would be 2x10), however you may see if rigid insulation will meet this requirement- d. Based on the floor plan, walls do not minimum bracing requirements of IRC 602.10 (also see State Amendtnents)_ Lateral calculations must be stamped and signed by a State Licensed Professional Engineer_ e. %' Anchor bolts gust be spaced no more than 6' o- c., located 12" of each end of each plate with minimum 7" embedment and 3"0" washers - f. Specify thickness of wall and roof sheathing, as well as nail spacing_ g. Note the kitchen addition on the site plan. Provide deck plans, including the roof cover over the deck. This must be included in this permit as well. See enclosed deck handout for minimum plaits and details. 4. Specify post and beam connections. 5- Alt wood in contact with concrete must be pressure treated or naturally resistant to decay (such as foundation redwood). Revise plans to show this where ever new members are being added. IRC 319.1. Page 2 of 2 city of edmonds development information 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 2006 Edition Washington State Ventilation & Indoor Air Quality Code 2006 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_ This handout provides the basic minimum codes for prescriptive compliance_ The basic prescriptive approach for energy code compliance 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 minimum U -value of all windows and doors for the project, and the insulation 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 (VIAQ) has been created as a means for bringing in fresh outdoor air, and exhausting interior stale air. The VIAQ code allows either a manual portal system or a mechanical system that runs unmonitored on a timer to convey the air.

Revised 7107 Ventilation System Operating Instructions Whole House Ventilation Systems Integrated with a Forced Air Heating System' Your new home has been constructed to use energy efficiently, while maintaining a healthy indoor environment with good supply of fresh air. To help you achieve these benefits, we recommend that you take a few minutes to read these instructions. Your home has been constructed to the most current requirements of the Washington State Energy Code (2003 edition) and the Washington State Ventilation and Indoor Air Quality Code (2003 edition). This means your home and the ductwork of your heating system have been well sealed, which limits uncontrolled exchange of air between the indoors and outdoors. The amount of fresh air provided to your home is under your control. You can increase the ventilation rate of your home by opening windows, or by operating your mechanical ventilation systems. Your home has two types of mechanical ventilation: spot ventilation fans, and a whole house ventilation system integrated with your heating system. �M� A spot fan has been installed in each bathroom, the utility room and the kitchen. if your home includes an indoor spa, or any other room that may need additional ventilation, a spot fan will be included there as well. /The purpose of spot ventilation is to control excess moisture, odors, or chemical byproducts at the source. It is far more effective to quickly eliminate moisture and pollutants when they are created than to allow them to dissipate slowly over time. Controlling moisture reduces the cause of many molds and protects the finishes of your home. Controlling odors and chemical byproducts reduces any health hazard that may be associated with It is particularly important to operate your kitchen fan if you have a gas or propane range. As well as removing moisture and odors created by cooking, your kitchen exhaust fan removes the unhealthy byproducts of combustion, including carbon monoxide and nitrogen oxides. Recommended spot fan operation: • Turn on the spot fan whenever moisture, odors, household chemicals, or combustion byproducts are present in the room, such as during shower- ing, washing clothes, or cooking- - Since moisture vapor, odors, and combustion byproducts tend to linger, run the spot fan for up to 60 minutes beyond the activity that produced them. Whole house ventilation integrated with the heating system. The forced air heating system in this home is equipped with a ventilation system. This system includes a fresh air intake connected to the return air duct (return air is the air that flows into your heating system), a damper that controls the amount of air that enters the system, and a timer that controls when the system operates. To change the amount of ventilation in your home adjust the timer to increase or decrease the time the system operates. In some cases you may also want to adjust the damper. Here's how the system works: 5UPPLY DUCT FRE5H AIR INTAKE= Figure 1. Whole house ventilation system integrated with a Forced air heating system. • When the ventilation timer calls for ventilation, the furnace fan motor turns on. If the ventila- tion system is equipped with a mechanical damper, it also opens. • The furnace fan pulls fresh air through the fresh air intake into the return air duct. • Fresh air is then distributed to the home through the supply air ducts of the heating system. • When the ventilation timer shuts off, the furnace fan motor turns off. If the system has a me- chanical damper, the damper also closes. Note: If your system is not equipped with a mechanical damper, your home will also receive ventilation whenever the system fan operates, including when it's on to provide heating or cooling. Selecting a Whole House Ventilation Schedule: Your contractor has set the timer on your ventilation system to provide a minimum of eight hours of ventilation per day. To get the maximum benefits of the system, you'll want to adjust the timer to suit your own schedule. • Run the system more when you expect to be home, or when more people are expected to be in the home. • Set the timer to cycle the system on and off for short periods. For example, 10 minutes on, 20 minutes off. • Use the manual control to turn the system on when large groups gather in your home.

Figure 3 identifies these dampers and describes how they work. This system uses the damper checked below. © Manual Damper ❑ Constant Air Flow Regulator ❑ Motorized Damper As required by code', your heating contractor has tested the flow reate of fresh air brought into your home and set the damper accordingly. Manual Damper Operation: In normal operating conditions, the damper is always open, regardless of the settings on the ventilation timer. The home receives ventilation whenever air handler fan turns on, or when the thermostat calls for heating or cooling. Using the timer to regulate the ventilation rate is always the hest choice. But because this system provides ventilation to the home whenever the air handler fan operates, ventilation rates may be excessive during very cold or very hot weather. This can mean wasted energy and an uncomfortable home. In this case, you may wish to adjust the manual damper. Before doing so, keep a few things in mind: • Before you change the damper setting, make note of the position of the damper adjustment. You will need to return the damper to this setting when the extreme weather passes. • Only reduce the ventilation rate when abso- lutely necessary. • Be aware for signs of under -ventilation, includ- ing smells and high humidity - rYln,,4;JAi.
