<br /> Overvlew The Chapter 5 Approach allows any combination of building envelope components as long as the
<br /> collective heat loss doesn't exceed a maximum limit established by code. The calculatlons on the lower part of this
<br /> page may be ignored N below grade wail insulation will efther be R19 on the interior or R10 exterior,or'rf the
<br /> basement wiil not be a habilable space and unheated, and the floor above is Insulated.
<br /> Page 2, Base Case Dwetllnp Calculation Compute areas using outer sur!aces for walls, ceilings (less skylfghts),
<br /> and floors. Use the rough framed opening areas for doors.The glazing area is derived by multiplying a constant
<br /> value (.15) by the sum ot the condttioned tloor areas(Don't include unheated attached yarages, etc).
<br /> Page 2, Proposed Dwelling Calculetlon Compute areas using outer surfaces for walls, cailings, and tloors. Use the
<br /> rough framed opening areas for doors and glazing. Since there are only four boxes on the torm for g�szing,combinr,
<br /> the a�eas oi units with the same Uo value into a singie entry. V�1SEC, Chapter 10, default values must be used for all
<br /> walls, ceilings, floors, untested doors/glazing, and to determine below-grade walVslab UA.
<br /> The Proposed Dwelling complys ff the the Proposed UA doesn't exceed the Base Case UA.
<br /> Transfer wall,celling;tloor,giazing, and do� r values(R and;U)to the Check Ilst.
