0 0 <br />Simple Heating System Size: Washington State <br />This heating system sizing calculator is based on the Prescriptive Requirements of the 2015 Washington State Energy Code (WSEC) and ACCA <br />Manuals J and S. This calculator will calculate heating loads only. ACCA procedures for sizing cooling systems should be used to determine cooling <br />loads. <br />The glazing (window) and door portion of this calculator assumes the installed glazing and door products have an area weighted average U-factor of <br />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 section, <br />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 Extension <br />Program at (360) 956-2042 for assistance. <br />Project Information Contact Information <br />Joel Hacck JAmerican Home Planners <br />(425)258-6400 <br />Heatina System Tyne: O All Other Systems O Heat Pump <br />To see detailed instructions for each section, place your cursor on the word 'Instructions". <br />Desian Temperature <br />Everett Paine AFB W Design Temperature Difference (AT) 49 <br />Area of Buildina <br />Conditioned Floor Area <br />Conditioned Floor Area (sq ft) <br />Average Ceiling Height <br />Average Ceiling Height (ft) <br />Glazing and Doors <br />Sk Iv iahts <br />Insulation <br />Attic <br />R 49 <br />Single Rafter or Joist Vaulted Ceilings <br />No Vaulted Cei ings .n tl+i5 pFojec[. <br />Above Grade Walls teas Figure 1) <br />R-21 Intermed ate <br />Floors <br />R-30 <br />Below Grade Walls (see Figure 1) <br />No Belo .
