<br />GENERAL DIRECTIONS
<br />
<br />1. New construction including additions which incorporates any of the lollowing leaiures cannot comply using this method: raised wood lloors without continuous slem walls, stel'l stud
<br />walls, single assembly roof/ceifing construction, or skylights or other non.vertical rool glass,
<br />2, Choose one of the component packages "A" through "F'lrom Table lOB by which you intend to comply with the Code, Circle Ihe column ollhe package you have chosen.
<br />3, On Table lOB you will find a column labeled "To Be Installed", In this column fill in all the applicable spaces with the information requested, All "To Be Installed" values must be eqlJ~1
<br />to or more efficjent Ihan the required levels,
<br />4. Complete Ihe Information requested on the top half of page 1 based on the "To Be Installed" column information.
<br />5. Re~d "Minimum Requirements for All Packages', Table 10A on page I, and check each box to Indicate your Intent to comply with all applicable items.
<br />6. Read, sign and date Ihe "Prepared By" cemlk:ation statement at the bonom 01 page 1. The owner or owner's agent must also sign and date the lorm,
<br />DESCRIPTION OF BUILDfNG COMPONENTS LISTED "
<br />
<br />Percent of Glass to Floor Mea: The percentage of total glass area to the conditioned f100r area shall not exceed the prescribed percentage, This percentag~ is calculated by dividing Ihe
<br />lotal of illl glass areas by the total conditioned floor area.
<br />Glass Type: In order 01 increasing energy efficiency, the glass types ~re: single'c1ear (SC), single-tint (ST), double'c1ear (DC) and doublelinl (OT).
<br />Overhang: The overhang is the distance the rool or soffit projects clut horizontally Irom the lace 01 the glass, All glass areas shall be under an overhang of at least lhe prescribed length with
<br />the lollowing exceptions: 1) glass on the gabled ends of a house and 2) the glass in the lower stories 01 a multi.story house,
<br />Wall, Ceiling and Floor Insulation Vllues: The R-values indicated represent the minimum acceplable insulation level added to the structural components 01 the wall, ceiling or IIoor. Tile
<br />R-v~lue of the structural building materials shall not be included in this calculation, "Common" components are those separating conditioned tenancies in a mullif~mily building "Adj~cenr
<br />components separate conditioned space from unconditioned but enclosed space. "Exterior' components separate conditioned space Irom unconditioned and unenclosed space,
<br />Floor: Slabon.grade floors without edge insulation are acceptable lor all packages, Raised wood IIoors shall have continuous stem walls with insulation placed either on the slem wall or
<br />under the floor.
<br />Ducts: "CONO' indicates thatlhe ducts must be inslalled within the conditioned space; Ihat is, the ductwork shall be located on the condilioned side ollhe insulation so that any leakage will
<br />be into the conditionlld space. Ducls In conditioned space are acceptable lor any prescriptive package, If "'NSUL" is specified, Ihe ducts may be in unconditioned space but must be insulated
<br />to a minimum installed insulation level of R.4,2 (R.6 alle,1I1/92).
<br />Space Cooling System: Cooling systems shall have a Seasonal Energy Efficiency Ratio (SEER) for central units or Energy Efficiency Ratio (EER) lor room units or PT AC's eqlJ~llo or
<br />greater than th!! prescribed value,
<br />Electric Space Heltlng Option: Heat pump systems shall be rated with a Heating Seasonal Performance Factor (HSPF) equal to or greater than the prescribed HSPF. He~t pump systems
<br />may contain electric strip backups meeting the criferia or section 903,8(b)3. "STRIP" means electric resistance heat is allowed lor that package.
<br />Gas or 011 Fuels Spice Heating Option: Gas or oil space heating syslems must be raled with an Annual Fuel Utilization Efficiency (AFUE) of at least the levels specilied tor 1991 and 19~2
<br />ElectrIc Resistance Hot Water Option: For "EF ,90" designation, the electric water healing system shall be rated with a minimum Energy Factor (EF) of at least .90. For pac~~ges
<br />designated "Not Allowed", an electric resistance hot water system may be installed only in conjunction with one 01 the "Other Hot Water System Options'. See below.
<br />Gas or 011 Fue'~ Hot Water Option: Gas 0' oil water heatirg systems must be rated with an Energy Factor (EF) 01 at least .54 lor all packages.
<br />Other Hot Wlter System Opllons: Any dedicated heat pump, heat recovery unil, or solar hot water system which meets the requirements of .oction 903.3(d) of th~ Energy Codo 'nay h~
<br />installed. Solar systems must be designed to provide at least 40% 01 the total hot water (solar fraction ot (40), Electric resistance systems having an EF 01 .B8 or gre~ter, or natur~1 l:m
<br />systems with EF .54 or greater may be used in conjunction with these systems,
<br />
