<br /> Overview The Chapter 5 Approach albwa any combination of bullding envebpe componeMs as lonp as the
<br /> collective heat bas doesnY exceed a maximum Iimit established by code. The cala�latbns on the bwer paA ot this
<br /> page may be igrared R below grade wall insulation will eRher be R19 on the itrierbr or R10 exterbr,or tl the
<br /> basement will not be a hebRable space and unheated, and tne ibor above ts insulated.
<br /> Paye 2, Basa Case Dwelllnp Calculatlon Compute areas usirq outer sur(aces for walls, celiings (less skyl�ghts),
<br /> and ibo�s. Use the rough framed openinp areas for doore.The glazinp area is dertved by multlplyinp a constant
<br /> value (.15) by the sum of the condftbned floor areas(Don't Include unheated attached garapes, etc).
<br /> Pape 2, Proposed Dwelilnp Celculatlon Compute areas using outer surtaces for walls,ceilinps, and floors. Use the
<br /> rough iramed opening areas for doors and glazing. Sfnce there are only four boxes on the form for glazinq,combine
<br /> the areas of units with the same Uo value into a single entry. WSEC, Chapter 10, default values must be used tor ali
<br /> walls, ceilings,fbors, untested doors/glazing, and to determine bebw-grade walUslab UA.
