6.11.9 Slab Construction

This data structure describes the composition of a slab-on-grade. There are many acceptable ways to represent slabs in energy simulation models. Some models have building descriptors for the perimeter length and the F-factor, which represents the heat loss per lineal foot. Other models require that the slab surface area within two feet of the building perimeter be specified along with the interior slab area. In the latter case, coefficients of heat loss either to the air temperature, the ground temperature, or both are linked to insulation configurations.
