<br />
<br />GENERAL DIRECTIONS;
<br />1, On Table 6C-t indicate the R-value of the Insulatlcn being added to each ccmponent and the efficiency levels cf the equipment being installed. All R-values and efficiencies installed must meet or exceed
<br />the minimum values listed, Components and equipment neither being added nor renovated may be lelt blank,
<br />2. ADOITIONS ONLY. Determine the percentage of new glass to conditioned floor area in the addition as follcws. Total the areas 01 all glass windows, sliding glass dccrs and glass door panels, Double the
<br />area of all nonvertlcal roof glass and add it to the previous total. When glass In existing exterior walls is being removed or enclosed by the addition, an amount equal to the tctal area of this glass may be
<br />subtracted from the total glass area. Divide the adjusted glass area total by the ccndltloned f10cr area 01 the addition, Multiply by 100 to get the percent. Rnd the largest glass percenlage under which your
<br />calculated percenlage falls on Table BC-2. Prescrlptives are given by the type 01 glass (single cr dOUble pane) and the cverhang (OH) paIred with a solar heat gain ccefficient (SHGC). For a given glass type
<br />and ' imum solar heat gain coefficient allowed is specified. Actual glass windows and dccrs previously In the exterior walls 01 the house nd being reinslalled In the addition do not have to
<br />co and sofar heat gain coefficient requirements on Table 6C-2. All new glass In the additicn must meet the requirement Icr cne 01 the cptlons in the glass percentage category you
<br />indicated. The over H) distance is measured perpendlcularty from the face cf the glass to a point directly under the outermost edge 01 tha overhang,
<br />3. RENOVATIONS ONLY. Replacement glass naeds to meet the follcwing requirements, Any glass type and sciar heat gain coefficient may be used lor glass areas which are under at least a 2-loot overhang
<br />and whose lowest edge does not axtend further than 8 feet from the overhang. Glass araas being rencvated that do not meet this criteria must be either single-pane tinted, dOUble-pane clear or double-pane
<br />tinted.
