<br /> basement wtll not be a habitabie space and unheated, and the floor above is insulated.
<br /> Pape 2, Bese Ceso Dwolllnp Calculation Compute areas using outer surlaces for walls, ceilings(less skytights),
<br /> and floors. Use the rough framed opentng areas tor doors.The glaztng area Is derfved by muftiplying a constam
<br /> value (.15) by the sum of lhe condfttoned fioor areas(DonY include unheated attached garages, etc).
<br /> Pape 2,Proposed DweII1nD Calculation Compute areas using outer surtaces for walls,cetlings, and iloors. Use the
<br /> rough Iramed opening areas for doors and glaztng. Since there are only four boxes on the lortn for glazing,combine
<br /> the areas of unfts wNh the same Uo value into a single 3ntry. WSEC, Chapt�r 10, default values must be used for all
<br /> walis, ceilings, fbors, untested doors/glazing, and ic determine below-grade walVslab UA.
