„uurpu: Hermit A <br />1997 WSEC Chapti 6 Qualification Form- A -a 1, Other fuels <br />Residential Prescriptive (Chapter 6) Options for Heat Source: Ot6erfue/s <br />instructions: <br />1) Carefully review the requirements for each of the options below. Choose an option that best suits your dwelling <br />design. Glazing percentage typically determines which option to choose. Your building must match the <br />selected option requirements without exceptions or substitutions. <br />2) Check ./ the 0 above the requirements of your option. Disregard components or equipment that do not <br />apply to your project. Your permit will be processed more efficiently if you provide all of the requested <br />information. Department staff can help ycu with general questions about this form. <br />Can't Comply? If none of the Prescriptive (Chapter 6) options are acceptable, consider the Component <br />Performance (Chapter 5) Approach. The main advantage is flexibility to juggle individual R and U-factors as long as <br />an overall maximum value isn't exceeded. Note that the Component Performance requirements are no less <br />stringent than the Prescriptive requirements. Calculations may be performed with a 1997 WSEC Chapter 5 <br />Residential Qualification Form, or by using an acceptable computer program such as WATTSUN. <br />OPTI OPT <br />CHECK ,/ one* <br />HVAC Efficient ' <br />0 <br />Med <br />II <br />0 <br />Mod <br />OPT III <br />0 <br />High <br />OPT IV <br />0 <br />Mod <br />OPT V <br />0 <br />Low <br />OPT VI' <br />0 <br />Med <br />O"30%unlimited <br />Glazing max: <br />%of floor' <br />10% <br />12% <br />21% <br />21% <br />21%, <br />25% <br />Vert.
