DESCRIPTION OF BUILDING COMPONENTS LISTED Percent 01 Glass to Floor Area: This percenlage is calculated by dividing the lolal of all glass areas by the total conditioned 1I00r area. Overhang: The overhang is the distance the roof or soffit projects out horizontally lrom the face 01 the glass. All glass areas shall be under an overhang of at teast the prescribed length wilh the following exceptions: 1) glass on Ihe gabled ends 01 a house and 2) the glass in the lower stories 01 a mulli.story house. Wall, Ceiling and Floor Insulation Values: The A-values indicated represent the minimum acceptable insulation level added to Ihe structural components of the wall, ceiling or 1I0or. The A.value of the slructural building materials shall not be Included in this calculation. 'Common" components are those separating conditioned tenancies in a mullilamity building. 'Adjacent" components separate conditioned space from unconditioned bul enclnsed space. 'Exlerior" componenls sepamte condilioned space trom unconditioned And unenclosed space. Floor: Slab.on-grade floors without edge Insulation are acceptable. Aaisod wood floors shall have conllnuous stem walls with Insula lion placed on Ihe stem wall or under the floor except Package D. Ducts: 'COND" Indicates Ihatlho ducts must be Inslalled within Ihe conditioned space; that is. Ihe ductwork shall be localed on Ihe condilloned side of the insulation. Ducts in condllloned space are acceplable for any prescriptive package. Space Cooting System: Cooling systems shall have a Seasonal Energy Efficiency Aatio (SEEA) lor central units or Energy Efficiency Aatio (EEA) for room unils or PTAC's equal 10 or grealer Ihan the prescribed value. Electric Space Heating Option: Heal pump syslems shall be rated with a Healing Seasonat Perionnance Factor (HSPF) equal to or grealer than the prescribed HSPF. Heat pump systems may conlaln electric slrlp backups meeling Ihe criteria of section 608.1.ABC.3.2. t .2. No electric resislance space heal is allowed for Ihese packages. Eleclric Resistance Hot Water Option: For packages designaled "Not Allowed", an electric resistance hol waler system may be Installed only In conjunction with one 01 Ihe 'Other Hot Waler System Oplions'. See below. Other Hot Water System Opllons: Any dedicated hoat pump, heat recovery unit, or sotar hol walm system may bo installed. Solar systems must have an EF 011.5 or higher. Electric reslslance syslems having an EF 01 ,88 or grealer, or natur,,1 gas systems with FF .54 or greater may be used In conjunctioo with these systems.
