[EnergyPlus_Support] Re: ASHRAE 90.1 and BuildingGroundSurfaceTemperature

["Ooi" <ooi_kb3@xxxxxxxxxxx>]

Niraj, 

i have not used the example file generator, so my answer has this preempt.

The Slab and Basement preprocessors are designed for specific cases. The Basement preprocessor only half or full height vertical insulation, no intermediate height insulation. Further, the ground covers up to the top of the basement walls. 

i have a nearly square 150 m2 wooden floor that is raised 400mm above ground. The floor is too cold in Melbourne Australia winter. Any suggestion on how to insulate?
