<br />GENERAL DIRECTIONS
<br />
<br />1, New construction including additions which incorporates any of the following features cannot comply using this method: raised wood floors without continuous stem walls, steel stud
<br />walls, single assembly roof/ceiling construction, or skylights or other non-vertical roof glass,
<br />2. Choose one of the component packages "A" through "F" from Table 10B by which you intend to comply with the Code, Circle the column of the package you have chosen,
<br />3, On Table 10B 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 equal
<br />to or more efficient than the required levels,
<br />4. Complete the information requested on the top half of page 1 based on the "To Be Installed" column information,
<br />5, Read "Minimum Requirements for All Packages", Table 10A on page 1, and check each box to indicate your intent to comply with all applicable items.
<br />6, Read, sign and date the "Prepared By" certification statement at the bottom of page 1, The owner or owner's agent must also sign and date the form,
<br />DESCRIPTION OF BUilDING COMPONENTS LISTED
<br />
<br />Percent of Glass to Floor Area: The percentage of total glass area to the conditioned floor area shall not exceed the prescribed percentage, This percentage is calculated by dividing the
<br />total of all glass areas by the total conditioned floor area,
<br />Glass Type: In order of increasing energy efficiency, the glass types are: single-clear (SC), single-tint (ST), double-clear (DC) and double-tint (DT).
<br />Overhang: The overhang is the distance the roof or soffit projects out horizontally from the face of the glass, All glass areas shall be under an overhang of at least the prescribed length with
<br />the following exceptions: 1) glass on the gabled ends of a house and 2) the glass in the lower stories of a multi.story house,
<br />Wall, Ceiling and Floor Insulation Values: The R-values indicated represent the minimum acceptable insulation level added to the structural components of the wall, ceiling or floor, The
<br />R-value of the structural building materials shall not be included in this calculation, "Common" components are those separating conditioned tenancies in a multifamily building, "Adjacent"
<br />components separate conditioned space from unconditioned but enclosed space, "Exterior" components separate conditioned space from unconditioned and unenclosed space,
<br />Floor: Slab-on-grade floors without edge insulation are acceptable for all packages, Raised wood floors shall have continuous stem walls with insulation placed either on the stem wall or
<br />under the floor.
<br />Ducts: "COND" indicates thatthe ducts must be installed within the conditioned space; that is, the ductwork shall be located on the conditioned side of the insulation so that any leakage will
<br />be into the conditioned space, Ducts in conditioned space are acceptable for any prescriptive package. If "INSUL" is specified, the ducts may be in unconditioned space but must be insulated
<br />to a minimum installed insulation level of R-4,2 (R-6 after 1/1/92),
<br />Space Cooling System: Cooling systems shall have a Seasonal Energy Efficiency Ratio (SEER) for central units or Energy Efficiency Ratio (EER) for room units or PTAC's equal to or
<br />greater than the prescribed value,
<br />Electric Space Heating Option: Heat pump systems shall be rated with a Heating Seasonal Performance Factor (HSPF) equal to or greater than the prescribed HSPF, Heat pump systems
<br />may contain electric strip backups meeting the criteria of section 903,8(b)3, "STRIP" means electric resistance heat is allowed for that package,
<br />Gas or Oil Fuels Space Heating Option: Gas or oil space heating systems must be rated with an Annual Fuel Utilization Efficiency (AFUE) of at least the levels specified for 1991 and 1992,
<br />Electric Resistance Hot Water Option: For "EF ,90" designation, the electric water heating system shall be rated with a minimum Energy Factor (EF) of at least ,90, For packages
<br />designated "Not Allowed", an electric resistance hot water system may be installed only in conjunction with one of the "Other Hot Water System Options", See below,
<br />Gas or Oil Fuels Hot Water Option: Gas or oil water heating systems must be rated with an Energy Factor (EF) of at least ,54 for all packages,
<br />Other Hot Water System Options: Any dedicated heat pump, heat recovery unit, or solar hot water system which meets the requirements of section 903,3(d) of the Energy Code may be
<br />installed. Solar systems must be designed to provide at least 40% of the total hot water (solar fraction of ,40), Electric resistance systems having an EF of ,88 or greater, or natural gas
<br />systems with EF ,54 or greater may be used in conjunction with these systems,
