<br />GENERAL DIRECTIONS: ., .
<br />1. On Table 6C-l indicate the R-value of the insulation being added to each compoi,ent ancithe efIIcieOcy levels of the equipment being insl8llad, All R-vaIues and etflCiencles installed must meet or exceed the minimum values
<br />listed, Components and equipment neither being added nor renovated may be Iefl blank.
<br />2, ADDITIONS ONLY, Delennlne the percenl8ge of new glass to conditioned floor area in the addition as lollows, T 0181 the areas 01 aU glass windows. sliding glass doors and glass door panels, Double the area of aU non-
<br />vertical roof glass end add ft to the previous total. When glass in existing eJrtariof.walls is being removed or enclosed by the addition, an amount equal to the 10181 area oIlhis glass may be 8UblracIed from the total glass area,
<br />Divide the adjusted glass area total by the COIllitioned floor area 01 the addilion, Multiply by 100 to get the percent, Find the largest glass percentage under which your caIc:ulated percentage falls on Table 6C-2. Prescriptlves
<br />are given by the type 01 glass (Single or Double pane) and the overhang (OH) paired with a shading coefIIcienl (SC), For a given glass type and overhang, the minimum shading coeIficienl aUowed is specified. Actual glass
<br />windows end 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 coeIficient requirements on Table 6C-2. All new glass in the addition
<br />must meet the requiremant for one 01 the options in the glass percentage category you indicated, The overhang (00) disIance is measured perpeI1dicldarlfrom the .face oI,the glass to 8:,~ direcUy~the outermost edge
<br />01 the overhang, '. '.
<br />3. RENOVA nONS ONLY. Replacemenl glass needs to meet the loIIowing requiremanls, Any glass type and shading coeIficienl may be used for glass areas which are under al\eaat a two loot overhang and whose lowest
<br />edge does not extend further than 81ee11rom the overhang. Glass areas being renovated that do not meet this criteria must be either s1ng1e-pane tinted. double-pane dear or doubIe-pane tinted.
<br />4. Complete the information requested on the lop han 01 page 1,
<br />5, Read "Minimum Requirements lor Small Additions and Renovations., Table 6C-3, and check all applicable lIems,
<br />6. Read, sign and date the 'OMlar/Agenr certilication statement on page 1.
