Sim;�le Heating System Size: Was�,;;i�iton State <br /> � 'This heating svstem sizinq calculator is based „�����e Prescriqtive Requirements of the 2012 Washinqt �te Enerqy Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads only ACCA procedures for sizinq cooling svstems should be used to determine coolinq <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 cal�the WSU Energy E�ension <br /> Program at(360)956-2042 for assistance. <br /> Project Information � Contact lnformation <br /> ,,, �.._. <br /> Plan 2435 <br /> Heatinq Svstem Tvpe: <br /> To see defai/ed instructions for each secfion,place your cursor on the word"lnsfructions". <br /> �esiqn Temperafure <br /> ;nstructions �•�-=--- ---�-----�—��-�- - Design Temperature Difference(4T) 46 <br /> �� <br /> �•.
