<br />HVAC Controls 607.1 Separate readily accessible manual or automatic thermostat for each system.
<br />
<br />GENERAl DIRECTIONS:
<br />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.values and efficieR:ies installed must meet or exceed the minilnurfrvalues1sted,
<br />Components and equipment neither being added nor reoovated may be left blank.
<br />2. ADDITIONS ONLY, Determi1ethe percentage of new glass to corllIIioned floor area in the a<kliOOn as follows, Total the areas of aI ~ windows, slicing ~ doors and ~ass door panels, Double the area ofalll1OlHellbltrool
<br />glass and add h to the previous total. When glass in existing exteriorwals is being reR1OI'ed or enclosed by the addition, an lIl1OUI1I equal to the total area of tt1s ~ may be SlbIracIed from the illaI ~ area, Divide.the &qusIed
<br />glass area total by the conditioned floor area of the acilition, MuflipIy by 100 to get the pen:ent, And thelargest glass pen:entage underwhicl1 yourcalculated peroentage fats on T able6C-2. PrescriptiYes are given bythe1)lle of glass
<br />(Single or Double pane) and the overhang (00) paired with a solar hear gain coefficient (SHGC), For a given glass type and overhang, the minimum solar heat gain coefficient allowed is specified. Actual glass windows and doors
<br />previO\JS~ in theexteriorwalls of the hoose and being reinstalled in the addition do not have to comply with the overhang andsolar heat gaincoefficient re<Jlirements on Table 6C-2. All new glass in the adlition must meet the requirement
<br />for one of the optionS in \he _ percentage ~ you indi:aled, The oveff1ang (OH) distance is measured perpendicularty from \he face of the glass to a poinldlreclty undertheoutennosl edge of !he oveff1ang.
<br />3, RENOV ATlONS ONLY. RepIa:ement ~ needs to meet the following requirements, Any glass type and mheat gain coefficient may be used for~ areas wt1ch are underat IeasI a two 1o?i oveIhang and who6e lowest edge
<br />does not extend furlherthan 8 feet from the oveIhang. Glass areas being rerovated that do not meet this criteria roost be either sige-pane tiied, 00ubIe-pa1e clear or double-pane tinted,
<br />4. BUILDING SYSTEMS. Comply when new system is installed for system installed.
<br />5. Complete the information requested on the top half of page 1.
<br />6. Read 'Minimum Requi'ements for Small Additions and Renovations', Table 6C-3, and check all app/ialIlIe items,
<br />7. Read, sig1 and date the 'Owner/Agenf cer1ificationstatemen1on page 1. _ 2 _
