IT <br />1997 WSEC Chapt <br />Residential Pr( <br />Instructions: <br />6 Qualification Form- ZLe'1; <br />for Heat Source: Other fuels <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 O abogg 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 you 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 Cor,.panent Performance requirements are no less <br />stringent than the Prescriptive requirements. Calculations, may be performed with a 1997 WSEC Chapter 5 <br />Residential Qualification Forth, or by using an acceptable computer program such as WATTSUN. <br />OPT I OPT II OPT III OPT IV OPT V OPT VI' Opt VII' Opt VIII <br />CHECK ✓ One ♦ <br />Q <br />Q <br />di, O <br />0 <br />V <br />O <br />O <br />O <br />HVAC Efficiency' <br />Mod <br />Mod <br />High <br />a <br />Med <br />Low <br />Mod <br />Mod <br />Mod <br />Glazing max: <br />% of floor' <br />10% <br />12% <br />21 % <br />21 % <br />21 % <br />25% <br />30% <br />unlimited <br />Vert.
