<br />GENERAL DIRECTIONS: ,. , ,
<br />1. On Table 6C-1 indicate the R-vaIue of the insulation being added to each component an<t'the efficieiK:y levels 01 the equipment being installed. All R-values and efficiencies installed must meet or exceed the minimum values
<br />listed. Components and equipment neither being added nor renovated may be left blank.
<br />2. ADDITIONS ONLY. Deten1line the pet'Cenl8ge 01 new glass to concfrtioned floor area in the addition es follows. Total the arees 01 all glass windoWs, sliding glass doors and glass door panels. Double the area of all non-
<br />vertical roof glass and add " to the previous total. When glass in existing e__aUs is being removed or enclosed by the addition, an amount eqUlI to the total area 0I1his glass may be subtracted from the total glass area.
<br />Divide the adjusted glass area total by the conditioned floor area 01 the addition. Multiply by 100 to get the percent. Find the largeSt glass percentage under which your caIculaled percentage falls on Table 6C-2. Prescriptives
<br />are given by the type of glass (Single or Double pane) and the overhang (OH) paired with a shading coefficient (SC). For a given glass type and overhang, the minimum shading coeffIcIenI allowed is specified. ActueI glass
<br />windows and doors previously in the exterior walls 01 the house and being reinstalled in the addition. do not have to comply with the overhang and shading coefticient requirementa on Table 6C-2. AU new glass in the addition
<br />musf meel the requirement for one of the options in the glass percentage ca1egory you indicaled. The overhang (00) distanCe is measured perpendiQJlarfy from lhe face of lhe glass tp.a ~ diredly Uf!der the outermost edge
<br />01 the overhang. . ..
<br />3. RENOVATIONS ONLY. Replacement glass needs to meet \he following requirements. Any glass type and shading coeftlcient may be used for glass areas which are under a11eas1 a two foot overhang and whose lowest
<br />edge does not extend further than 8 feet from the overhang. Glass arees being renovated that do not meet this criteria must be either single-pane tinted, doubIe-pane clear or dou\lIH808 tinted.
<br />4. Complete the information requested on the top half 01 page 1.
<br />5. Read "Minimum Requirements for Small Additions and Renovations', Table 6C-3, and check all applicable ilems.
<br />6. Read, sign and date the "Owner/Agent" certification statement on page 1.
