<br />DESCRIPTION OF BUILDING COMPONENTS USTED
<br />Percent of Glas. 10 Roor Area: This percentage is calculated by dividing the total of all glass areas by the total conditioned noer area,
<br />Overhang: The overhang is the distance the rool or soffit projects out honzontally from the face of the glass, All glass areas shall be under an overhang of at least the prescnbed length with the following exceptions: 1) glass
<br />on the gabled ends 01 a house and 2) the glass in the lower stories of a mufli.stol'f house.
<br />WIll, Ceiling Ind Floor Insulation Vllues: The R-values indicated represent the minimum acceptable insulation level added to the structural components 01 the wall, ceiling or floor. The R-value 01 the structural bUilding
<br />malenals shall not be included in this calculation. 'Common' components are those separating conditioned tenancies in a multifamily building. 'Adjacenr componenls separate conditioned space from unconditioned but
<br />endosed space, .Exterior" components separate conditioned space from unconditioned and unenclosed space,
<br />Floor: Slalron"9rade floors without edge insulation are acceptable, Raised wood noers shall have continuous stem walls with insulation placed on the stem wallar under the noor except Package 0,
<br />Ducts: "CONO" indicates that the ducts must be installed within the conditioned space; that is, the ductwork shall be located on the conditioned side of the Insulation, Ducts in conditioned space are acceptable for any
<br />prescriptive package,
<br />Space Cooling System: Cooling systems shall have a Seasonal Energy Efficiency Ratio (SEER) lor central units or Energy Efficiency Ratio (EER) for room units or PT AC's equal to or greater than the prescnbed value,
<br />Electric Spice Hllting Option: Heal pump systems shall be rated with a Heating Seasonal Performance Factor (HSPF) equal to or greater than the presenbed HSPF, Heal pump systems may contain eleclnc stnp backups
<br />meeting the criteria of section 608.t.ABC,3.2.1,2. No electnc resistance space heat is allowed for these packages.
<br />Electric Resistance Hot Water Option: For packages designated "Not Allowed", an electric resistance hot water syste:n may be installed only in conjunction with one of the "Other Hot Water System Options", See below,
<br />Other Hot WIler System OptJons: My dedicated heat pump, heat recovel'f unit, or solar hot water system may be installed. Solar systems must have an EF of t,5 or higher, E1ectnc reSIStance systems haVIng an EF 01 ,88
<br />or greater, or natural gas systems with EF ,54 or greater may be used in conjunction with these systems,
