<br />" New construction including additions which incorporates any ollhe following fealuras cannot comply using Ihis method: raised wood f100rs without continuous Ilem Wills, sllel stud
<br />walls, single assembly rool/ceiling construc1ion, or skylights or othar non-vertical rool glas~.
<br />2, Choose one of the component packages 'A.through"F' Irom Table 109 by which you intend 10 comply with the Coda, Circlathe column of the package you have chaSin,
<br />3, On Table lOB you will find a column labeled "To Balnslalled., In thl~ column fin In all the applicable spaces with the information requested. An "To Be Installed" value! mUlt be equal
<br />to or more efficienllhan the required levels.
<br />4. Complete the information requested on the top hall 01 page' b3sed on the "To Be Installed. column Information.
<br />5 Read 'Minimum RequiremenlS for All Packages', Table 1 M on page', and check each box 10 Indlcata your inlentto comply with all appncable items.
<br />6, Read, sign and date the 'Prepared By" certification slalement althe bol1om of page 1. The owner or owne(s aoent must also sign and date the form.
<br />DESCRtPTION OF BUILDING COMPONENT9 USTED
<br />
<br />Percent of GillS to Ftoor Aret: The percenlagl of Iotal glass area 10 the conditioned ftoor area shan not exceed tha prescribed percentage, this percenlage is calculated by dividing the
<br />total of all glass areas by the total conditioned IIoor area,
<br />Glus Type: In order 01 increasing energy efficiency, the glass types ara: single-dear (SC), single,tint (ST), double-dear (DC) and double-tint (OT).
<br />Overhang: The overhang is the distance the rool or soffil projects out horizontally from the laca of the gless. All glass areas shall be under an overhang of alleastthe prescribed length with
<br />the lollowing exceptions: 1) glass on the gabled ends 01 a house and 2) the glass in the lower stories of a multi-story house.
<br />Wall, Ceiling and Floor Insulltlon Vllu": The R,values indicated represent the mlnlmum acceptable insulation lavel added to tha structural componanlS of the wan, ceiling or "oor. The
<br />R,value of the structural building materials shall not be included in this calculation, .Common. components ar~ those separaling conditioned tenancles In a multifamily building, .Adjacent.
<br />components separate conditioned space from uncondilioned but enclosed space. .Exterior" components separate conditioned space from unconditioned and unenclosed space.
<br />Floor: Slabon'grade IIoors wilhout edge insulation are acceptable lor an packages. Raised wood floors shan havI continuous stem wans wtltt Insulation placed either on the stem wan or
<br />under the floor.
<br />Ducts: 'CONO' indicates thallhe ducts must be installed within the conditioned space; that Is, the ductwolil shall be located on lhe conditioned side of the Insulation so that any leakage win
<br />be into the conditioned space. Ducts in conditioned space are acceptable for any prescriptive package. ".INSUl.ls speclftad,the ducts may be In unconditioned spaca but must be IMulated
<br />to a minimum installed insulation level of R.4,2 (R'6 alter 1/1/92).
<br />Space Cooling Syslem: Cooling systems shall have I Seasonal Energy Efficiency Ratio (SEER) for cen"ll units or Energy Effidency Ratio (EER) for room units or PT AC's equal 10 or
<br />greater than the prescribed value.
<br />Electric Space Heating Option: Heat pump systems shan be rated with a Heating Seasonal Parformance Factor (HSPF) aqualto or grealer lhan Itte prescribed HSPF, Heal pump systems
<br />may contain electric strip backups meeting Itte criteria of section 903,8(b)3. .STRIP' means elactrlc resistance heltls aUowed for that package, ,
<br />Ou or 011 Fuels Spice Heltlng Option: Gas or oil space healing systems must be rated with an AnnUli Fuel Utilization Ellldency (AFUEI of at least the levels specified for 1991 and 1992,
<br />Electric Rulstance Hot Wlter Option: For 'EF .90' designation, the electric water healing syslem shall be rated with a minimum energy Factor (EF) 01 allaast.90, For packages
<br />designated "Not Allowed', an etec1ric resistance hot water system may be inslaned only In conjunction with one of the "Othar Hot Water Systam OptIons'. See below.
<br />Gu or on Fuels Hot Wal. Option: Gas or oil water heating systems must be raled with an Energy Factor (EF) of at least .54 for an packages,
<br />Oth@r Hot Waler Syslem Option.: Any dedicated heat pump, heat recovery unit, or solar hol water system which meels the requirements 01 section 903,3(d) 01 the Energy Code may be
<br />installed. Solar systems must be designed 10 provide alleast40"lo of the lolal hot waler (solar fraction of ,40). Elactrlc resistance systems havlng an EF 01 .88 or greater, or nalural gas
<br />systems with EF .54 or greater may be used in conjunction with these syslems.
