For fhis worksheet consider the tollowinq prescriptive requirements: O Slab insulatlon R-10 O Below prade walls R-10 exterior or R-19 fnterior O Standard iniiltration control Ii you choose to use an altemate to the above prascriptive requirements, confacc your JurisdicUon for information on comptiance for ihe Companent Perfortnance Apprwch, Chapter 5. 6UILDING COMPONEIR COLUMN The buildinp componaM column tndudes several IGstlnps tor each rype of camponent so that componeMs with different U-values may be listed separatey. A detailed cross sectlon of each of the wall, ceilinp and 11oor buildin0 �Ponems shouid be provided on the plans and the U-value and R-values of each element in the usemby stawn. O PROPQSED uHOSSAREA: Detemiine the pmss (total) area for each buildinp compo- nent and record in cdumn A The pross area and the net area are the same for the windaws, doors, skyliphts and floors. O PBOPOSEDNETAREA: Dotermine the net area tor each buildinp component and rocoN in column B. The net area for the walls and roof equals the pross wall or rooi area minus the openinq area - windows, doors, skyitphts, etc. O BASE CASE AREII• Determine the base case area and record in column C. The base cau area for waiis is fhe total wall area minus the base case window area. Record total base case wall area in column C, row - walts t. The base case area for windows, sBdinp plass doors and other doors that are substantialty O�ss must add up to 15% of the condidoned floor area. The skylipht area is not Induded (n Me base pse scererio. CondidonedFloorAreax.l5=_ Recordthenumber from above fn column C, row - windows 1. The base case areas tor the ceiliiprs, floors and non-plass doors is the same u the proposed net area for those buildinp compo- n�ts. The Oase pse areas aro the areas used when determinfnp the requirod UA O REOUIBED-CODE-U-YALUES: The U-values Iisted are the minimum required U-values shoxm in Table 5-1 NWEC for Zone I, Low-rise R-3 and R-1. See 7able 5-2 for the requ(red U-values tor Zone II. 0 P80POSED MEASUNETO BEINSTALLED: The proposed measure is the R-value of the insuiatlon in the buiWinp componeM (walls, ceilinps, floors) or the tested U- value of the building component (windows, doars, sky- liqhts, etc.). O PROPOSED U-VALUE Determfne the total U-value of each buildinq component assembty and record in column F. The default U-values for different types of materials pn be tound in the Appendix C DefauR U-values fmm the Sfate Enerpy Office.l-800-962- 9731 The U-value is the inverse of the R-value. � REpUiHED UA: Muldpy the base case areas in column C by the required U- values in column D for each �uildirq component and record in column G. 0 PHOPOSED UA: Muldply the net areas in column B by the proposed U- values (n column F for each buildinp componem and record in column H. O UA DIFFERENCE Add alt of the buiidinp componeM �21ues in the requtred UA cdumn G and record at the boGom of Ihe column in the box tor tohls. Add ali of the buildinp component vaiues in the proposed UA column H and record at the botrom oi the cdumn in the box for totals. Subtract fhe rotal proposed UA fn column H trom fhe toW requtred UA In column G and record in the box for totals In column I. it the answer is a positive number then the proposed areas and U-values compy with the Chapter 5 approach to the NWEC. If the total is a nepative number then the proposed areas and U-values do not compty with the Chapter 5 approach to the NWEC. If tha proposed areas and U-ralues do not comply. Review the numbers in the UA columns G and H. You must decrease the U-value (increase the fnsulatlon) or area for one or moro of the buiidfnp companents to make the project compiyl Once you have charped either the U-value or proposed area tor the buildinp component(s). Flnd the new proposed UA and add up the column apain. If the total of the UA ditterence is positive then the project complies with the code. Ii the numDer is neqative try another buildinp component or further decrease the U-value until the total tor the UA difierence (s positive.
