�� V' p`t�� ,d � s,�.`t j 13 Simple Heating System Size: Washington State � This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Enerqv Code (WSEC) and ACCA Manuals J and S. This calculator will calculate heatinq loads onlv. ACCA procedures for sizina coolina svstems should be used to determine coolinq loads. The glazing (window) and door portion of this calculator assumes the installed glazing and door products have an area weighted average U-factor of 0.30. The incorporated insulation requirements are the minimum prescriptive amounts specified by the 2012 WSEC. P�ease fill out all of the green drop-downs and boxes that are appiicable to your project. As you make selections in the drop-downs for each 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 Extension Program at (360) 956-2042 for assistance.
