GENERAL DIRECTIONS:
1. On Table 6C 1 Indicate the R-value of the insulation being added to each component and the efficiency levels of the equipment being installed.All R-vahres and effidenpies igstatled must meet coed the rrinimum,values
listed.Components and equipment neither being added nor renovated may be left blank. '; , ." (�) ' r.
2. ADDITIONS ONLY.Determine the percentage of new glass to conditioned floor area In the addition as follows.Total the areas of all glass windows,sliding glass doors%r4'0ass dooi f anet a the area of all non-
vertical roof glass and add it to the previous total.when glass in existing exterior wall is being removed or enclosed by the addition,an amount equal to the total area of,d s glass may b the(otai glass area
Divide the adjusted glass area total by the conditioned floor area d the addition.Mulfipy by 100 to gel the percent.Fmd the largest glass percentage under which your caladated�percenta falls 6C-3.Pr,�iptives
are given by the type of glass(Single or Double pane)and the ovedrarng(Oft)paired with a shading coefficient(SC).For a given glass type and ovefiang,the minimum shaduigcoefficient ow i ed. glass
windows and doors previously in the exterior walls of the house and being reinstalled in the addition.do not have to comply with the overhang and shading coefficient requirements'9 Table pddton
must meet the requirement for one of the options in the glass percentage category you Indicated.The overhang(OM distance is measured perpendicularly from the face of the gtas§tn3 point c. st edge
of the overharhg. t h
3. RENOVATIONS ONLY.Replacement glass needs to meet the following requirements.Any glass type and shading coefficient may be used for glass areas which are under at least a two i t ' and Am lowest
edge does not extend further than 8 feet from the overhang.Glass areas being renovated that do not meet this criteria must be either single-pane tinted,double-pane cloaca double-pane lint
