Prescriptive Energy Code Compliance for All Climate Zones in Washington Simple Heatin System Size: Washington State
<br /> This heatin s stem sizin calculator is based on the Prescri tive Re uirements of the 2012 Washin ton State Ener Code WSEC and ACCA
<br /> Project Information Contact Information Manuals J and S.This calculator will calculate heatin loads onl .ACCA rocedures for sizin coolin s stems should be used to determine coolin

<br /> HAACK BROTFiERS The glazing(window)and door portion of this calculator assumes the instalied 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 calcu{ated for you. If you do not see the selection you need in the drop-down options, please call the WSU Energy Extension
<br /> This project will use the requirements of the Prescriptive Path below and incorporate the Program at(360)956-2042 for assistance.
<br /> the minimum values listed.In addition,based on the size of the structure,the appropriate
<br /> number of additional credits are checked as chosen by the permit applicant. Project lnformation Contact Informarion
