Department staff can help you with general questions about this form. <br />Can't comply? If none of the Chapter 6.Options are acceptable, consider the Chapter 5, Component <br />Performance, Approach. The main advantage is flexibility to juggle individual R and U-values as long as a n <br />overall maximum value isn't exceeded. Note that the overall thermal requirements of Chapter.; are no loss <br />stringent than ;hapter 6. Calculations may be performed with a Chapter 5, Component Performance <br />Worksheet, or by using an acceptable computer program such as WATTSUN 5.1. <br />Approved by: <br />Date: <br />WEES'NORAMEPTEMeER 1991 <br />OPOT I I OPT011 I OPT0III I OPT0 IV <br />HVAC AFUE z.78 a.78 <br />Glazing max: <br />% of floor 10% 12% <br />U-value 2 0.70 0.65 <br />Door U•value 2 1 0.40 1 0.40 <br />(R-value) I (R-2.5) (R-2.5) <br />Ceilings: <br />with attics <br />vaulted <br />Walls: <br />above grade <br />below grade <br />interior <br />or exterior <br />Floor <br />Slab on grade <br />M-11:11111111 <br />w <br />R-30 <br />R-30 <br />R-30 <br />R-30 <br />R-30 <br />R-30 <br />R-15 <br />R-15 <br />R-19 <br />R-15 <br />R-15 <br />R-19 <br />R-10 <br />R-10 <br />R-10 <br />R-19 I R-19 <br />R-10 R-10 <br />21% <br />0.65 <br />0.40 <br />(R-2.5) <br />R-30 <br />R-30 <br />OPT V <br />01 <br />I (s2.,Wh <br />O <br />a .74 <br />'. a .78 <br />21% <br />25% <br />0.60 <br />0.50 <br />0.40 <br />0.40 <br />(R-2.5) <br />(R-2.5) <br />R-30 <br />R-38 <br />R-30 <br />R-30 <br />R-19 I R-19 R-19 <br />R-19 I R-19 R-19 <br />R-10 R-10 R-10 <br />R-19 R-19 <br />R-10 R-10 <br />R-1 <br />R-19 R-25 R- <br />R-10 R-10 R- <br />Footnotes: <br />1) The "a" symbol moans "more than or equal to"; "s"means "lose than or equal to". <br />2) Glazing G door U-values may be weighted If they don't exceed the Option U-value. <br />
