s <br />Simple Heating System Size: wasnTngton State <br />This heating system sizing calculator is based on the Prescriptive Requirements of the 2015 Washington State Energy Code (WSEC) and <br />ACCA Manuals J and S. This calculator will calculate heating loads only. ACCA procedures for sizing cooling systems should be used to <br />determine cooling loads. <br />The glazing (window) and door portion of this calculator assumes the installed glazing and door products have an area weighted average U- <br />factor of 0.30. The incorporated insulation requirements are the minimum prescriptive amounts specified by the 2015 WSEC. <br />Please fill out all of the green drop -downs and boxes that are applicable to your project. As you make selections in the drop -downs for each <br />section, some values will be calculated for you. If you do not see the selection you need in the drop -down options, please call the WSU Energy <br />Extension Program at (360) 956-2042 for assistance. <br />Project Information Contact Information <br />FETTIG RESIDENCE REMODEL SIALER DESIGN LLC <br />5103 RUCKER AVE 16008 MOTOR PL <br />EVERETT, WA98203 LYNNWOOD, WA98087 <br />Heatina System Type: 0All Other systems O Heat Pump <br />To see detailed instructions for each section, place your cursor on the word "Instructions". <br />Design Temperature <br />Instructions Design Temperature Difference (AT) <br />Everett Paine AFB AT= Indoor (70degrees) -OtddxrDesign Temp <br />Area of Building <br />Conditioned Floor Area <br />Instructions Conditioned Floor Area (sq ft) <br />240 <br />Average Ceiling Height <br />Conditioned Volume <br />Instructions Average Ceiling Height (ft) <br />7.0 <br />1,680 <br />Glazina and Doors <br />U-Factor X <br />Area = <br />UA <br />Instructions <br />37 <br />11.13 <br />0.30 <br />Skylights <br />U-Factor X <br />Area = <br />UA <br />Instructions <br />0.50 <br />--- <br />Insulation <br />Attic <br />U-Factor X <br />Area = <br />UA <br />Instructions Select R-Value <br />No selection <br />0 <br />--- <br />Single Rafter or Joist Vaulted Ceilings <br />U-Factor X <br />Area <br />UA <br />Instructions Select R-Value <br />No selection <br />Above Grade Walls (see Figure 1) <br />U-Factor X <br />Area <br />UA <br />Instructions <br />R-21 intermediate <br />illimmom <br />0.056 <br />213 <br />11.93 <br />Floors <br />U-Factor X <br />Area <br />UA <br />Instructions <br />Select R-Value —�;i <br />No selection <br />0 <br />--- <br />Below Grade Walls (see Figure 1) <br />U-Factor X <br />Area <br />UA <br />Instructions <br />Select R-value <br />No selection <br />Ell I <br />0 <br />--- <br />Slab Below Grade (see Figure 1) <br />F-Factor X <br />Length <br />UA <br />Instructions <br />Select conditionin <br />- No selection <br />II�-�I <br />--- <br />Slab on Grade (see Figure 1) <br />F-Factor X <br />Length <br />UA <br />Instructions Select R—Value <br />sYYi'rtr wwrrrul4nir"i+sctialiitlwi� S S'iHii'ii7�iiWtitl <br />.
