Ecotope Group, for Bonneville Power Administration, 1988. _ Insulation is extruded polystyrene, R m 5.0 h it2 I’l’i’Btu-in. (SI: R = 34.7 m KIW). Soil conductivity is 0.75 Btulh ft “F (1.30 WIK m). - N0 thermal break at edge of slab, where 50 indicated. If a thermal break is provided with horizontal insulation, use fite corresponding value for vertical insulation. Values assume an unheated slab (as per data in Table A—16 of ANSVASHRAEHESNA Standard 90.1-2001, Energy Standard for Budding: Brcept tow—Rise Residential Buildings); F2 values increase substantially when slab is heated.
