. Simple Heating System Size: W�gton State • <br /> This heatinq sysh.m sizing calculator is based on the Prescriptive Reauirements of lhe 2015 Washinqton State Enerqv Code(WSEC)and ACCA Manuals <br /> J and S.This calculator will calculate heatinq loads oniv.ACCA procedures for sizinq coolinq svstems should be used to determine coolinq loads. <br /> The giazing (windov✓)and door portion of this calculator assumes the installed glazing and door products have an area weighted average U-factor of 0.30. <br /> � The incorporated insulation requirements are the minimum prescriptive amounts specified bythe 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,some <br /> values will be cal�:ulated for you. If you do not see the selection you need in the drop-down options,please call the WSU Energy Extension Program at <br /> (360)956-2042 for assistance. <br /> Projeci Inlormation Gontact Information <br /> 12x24 Addition Lyle Spink <br /> 2412 81st PI.SE <br /> Everett,WA 98203 <br /> Heatinq Svstem Tvpe: O nu orne�sYst�S O Heat Pump <br /> To see defailed instructions lor each section,place your cursor on the word"Instructions". <br /> C�esiqn Temperature <br /> �"'°xP�'�'=`i°r"� � -� �- Design Temperature Difference(4T) 49 <br /> Everett Paine AFB � � :\T=Indoor(70 degrees)-Outdoor Design Temp <br /> w� <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> �"`''E"=t1OF'� Conditioned Floor Area(sq ft) 288 <br /> Average Ceiling Height Conditioned Volume <br /> in:;truct�nrs Average Ceiling Height(ft) 8.1 2,333 <br /> GI<�zinq and Doors U-Factor X Area - UA <br /> �i�lBtruCfi6€9� <br /> 0.30 20 6.00 <br /> Sk I�qhts U-Factor X Area - UA <br /> In��trucRi;�ns 0.50 � --- <br /> In�;ulation <br /> Attic U-Factor X Area UA <br /> In�.truct€ons ` 0.026 288 7.49 <br /> R49 � ,;. <br /> ...:w �i.�aS�.1��:.,�''»'._.�""�.�'.aC������� . <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> i��struclions .. � � <br /> No VaultNd C�dmgs in this pro7ect � --- <br /> � .
