Buildings, or portions thereof, separated from the <br /> remainder of the building by building thermal envelope assemblies complying with this <br /> code and with a peak design rate of energy usage less than 3.4 Btu/h•ft2 (10.7 W/ m2) or <br /> 1.0 watt/ft2 (10.7 W/m2) of floor area for space conditioning purposes shall be exempt <br /> from the building thermal envelope provisions of this code." <br /> <br /> (3) Amending Section 202. Section 202, General Definitions, is amended by adding a <br /> definition for "Fully Shaded Windows" to read: <br /> <br /> "FULLY SHADED WINDOWS.

Section 401.1 is amended to read: <br /> <br /> "401.1 Scope. This chapter applies to residential buildings, including those that do not <br /> contain conditioned space." <br /> <br /> <br /> (5) Amending Table 402.1.1.
