ti <br />Simple Heating System Size: Washington State <br />This heating system sizino calculator is based on the Prescriptive Requirements of the 2012 Washington State Energy Code fWSEC) and ACCA <br />Manuals J and S. This calculator will calculate heatina loads only. ACCA procedures for sizino coolino s stems 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 2012 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 />PLAN #2064 PAUL BUSTARD <br />425-876-6551' <br />Heating System Type: ! rorced Air Furnace Heat rump <br />To see detailed instructions for each section, place your cursor or, the word "Instructions". <br />Design Temperature <br />instruc;inns — — -- Design Temperature Difference (AT) 49 <br />i Brett Paine AFB ; r - tndacr (70 cegrees) • Outdoor Jos;gn Temp <br />a <br />Area of Building <br />Conditioned Floor Area <br />Instruction, Conditioned Floor Area (sq ft) <br />Average Ceiling Height <br />Instructions Average Ceiling Height (ft) <br />Glazing and Doors <br />Instructions <br />Insulation <br />Attic <br />instructions R-49 � <br />Single Rafter or Joist Vaulted Ceilings <br />lnstrucizon:: s <br />Select R Value <br />• <br />Above Grade Walls (see Figure t) <br />Instnicti�ns S R 2i <br />• <br />Floors <br />t;isirurtions R <br />Below Grade Walls (see Figure t) <br />intiirrtcttons _�"�.'
