<br />
<br />GENERAL DIRECTIONS:
<br />1. On Table 6C.l ind'lCale the R.value of \he insulation being added to each component and the enlciency levels 01 the equipment being instaBed, All R,valueS and elficiencles inslaned must meet or exceed the minimum values
<br />fisted, Components and equipment neither being added nor renovated may be left blank,
<br />2, ADDITIONS ONLY, Determine \he percentage of ~ gtass.lo conditioned floor area in \he addition as Iollows, To1al\he areas 01 all glass windows. sliding glass doors and glass door panels, DcuIlIo \he .rea of aft non,
<br />vertical rool glass and add " to the previous total. When glass In existing exterior wans is being removed or enclosed by \he addition. an amount equal to the to1al area oIlhis glass may be subtracted !rom \he IOlal glass area,
<br />Divide the adjusted glass area total by \he concItioned floor area 01 \he addition, Multiply by 100 to get the percent, Find the largest glass percentage under whiCh your calculated percentage 'altt On Table 6C,2, PraSCriptives I
<br />are given by the type 01 glass (Single or Double pane) and \he ovemang (00) paired with a shading coeIIicient (SC), For a given glass type and overhang, \he minimum shading coell'ocient allowed is specified, AClua' glass
<br />windows and doors previously In tha exterior wans 01 the house and being rainstaned In the addition. do not have to comply with the ovemang and shading coelf'lcient requirements on Table 6C,2. AI new glass in the addition
<br />must meelthe requlrement for one 01 the options In the glass percentage category you 1ndicaIed, The overhang (00) distance is measured perpendicularly trom the lace of \he glad 10 . point directly under \he outermost edge
<br />of \he ovemang,
<br />3, RENOVATIONS ONLY, Replacemenl glass needs to meet the tollowing requirements, Any glass type and shading coefficient may be used for glass areas which are under at least a Iwo loot ovemanil and whose lowest
<br />edge does not extend further than Bleet Irom \he overhang, Glass areas being renovated that do not meet this criteria musl be either single,pane tinted. doubIe'pane clear or double,pane tinted,
<br />4, Complete the Inlormation requested on :he top hall of page 1,
<br />5, Read -Minimum Requirements for Small Additions and Renovations', Table 6C,3. and check all applicable items,
<br />6, Read. sign and date the "Owner/Agent" certification ~atement on page 1,
