<br />If yes: Exposed roof/Ceiling assemblies must be insulated -
<br />Vaulted ceilings Insulate to the full depth of the framing member
<br />while allowing for the minimum 1" ventilated space
<br />Fiat ceilings: Install R-49 insulation or what the attic Space can
<br />accommodate based on the roof pitch
<br />Will the floor framing cavities be exposed? F Yes F No

<br />Are the Win ai rid/or doom being replaced Yes FNo
<br />(includes both Wndavil or door and frames)
<br />If yes: New windows and doors must have an area weighted average U-factor of <0.30

<br />11.503,1.1 Building envelope. Building envelope assemblies that are part of the alteration shall comply with Section
<br />R402.1.1 or R402.1.4, Sections R402.2.1 through R402.2.11, R402.3.1, R402.3.2, R402.4.3 and R402.4.4.
<br />Exception; The following alterations need not comply with the requirements for new construction provided
<br />the energy Use of the building is not increased:
<br />1. Storm windows installed over existing fenestration.
<br />2. Existing ceiling, wall or floor cavities exposed during construction provided that these cavities are filled
<br />with insulation. 2x4 framed walls shall be insulated to a minimum of R-15 and 2x6 framed walls shall be
<br />insulated to a minimurn of R-21.
<br />3. Construction where the existing roof, wall or floor cavity is riot exposed.
<br />4. Roof recover.
<br />5. Roofs without insulation in the cavity and when the sheathing or insulation is exposed during reroofing
<br />shall be insulated either above or below the sheathing.
<br />6. Surface -applied window film installed on existing single pane fenestration assemblies to reduce solar
<br />heat gain provided the code does not require the glazing fenestration to be replaced.
<br />111503.1.1.1 Replacement fenestration. Where some or all of an existing fenestration unit is replaced with a new
<br />fenestration product, including sash and glazing, the replacement fenestration unit shall meet the applicable
<br />requirements for U-factor and SHGC in Table R402.1.1. Where more than one replacement fenestration unit is being
<br />installed, an area -weighted average of the U-factor and SHGC of all replacement fenestration shall be permitted to be
<br />used to demonstrate compliance.
<br />R503.1.2 Heating and cooling systems. New heating, cooling and duct systems that are part of the
<br />alteration shall comply with .Section R403.
<br />Exceptions:
<br />1. Where ducts from an existing heating and cooling system are extended, duct systems with less than 40 linear feet in
<br />unconditioned spaces shall not be required to be tested in accordance with Section R403.2.2.
<br />2. Existing duct systems constructed, insulated or sealed with asbestos.
<br />R502.1,1.2 Heating and cooling systems, New heating, cooling and duct systems that are part of the addition shall
<br />comply/ with Section R403,
<br />Exception: The following need not comply with the testing requirements of Section R403.3.3:
<br />1. Additions of less than 750 square feet.
<br />2. Duct systems that are documented to have been previously sealed as confirmed through field
<br />verification and diagnostic testing in accordance with procedures in WSU RS-33.
<br />3. Ducts with less than 40 linear feet in Unconditioned spaces.
<br />4. Existing duct systems constructed, insulated or sealed with asbestos.
<br />R503,1,3 Service hot water systems. New service hot water systems that are part of the alteration shall comply with
<br />Section R403.5.
<br />R503.1.4 Lighting. Nev-j lighting systems that are part of the alteration shall comply with Section R404.1.
<br />Exception: Alterations that replace less than 50 percent of the luminaires in a space, provided that such
<br />alterations do not increase the installed interior lighting power.
<br />R.503.2 Change in space conditioning. Any nonconditioned or love -energy space that is altered to become conditioned
<br />space shall be required to be brought into full compliance with this code.
