[Equest-users] How to model floor using aluminium foil to prevent heat transfer?

[Bishop, Bill]

Shubha,
I would add baseboard heating with hot water coils to the conditioned
space, and assign a high thermal mass and poor insulation to the floor
construction. Set the DESIGN-HEAT-T in the basement to the temperature
you think it will be when the conditioned space is in peak heating mode.
Likewise for DESIGN-COOL-T and peak cooling.
Regards,
Bill

preventheat transfer?
 
Hi,
 
The building i am modeling has steel frame floor which separates the
conditioned space from unconditioned basement. There are hot water tubes
running underneath between the steel joists for radiant heating. There
is no use of insulation except for v thin aluminium foil below radiant
tubes which is fixed to the steel joists using magnets. This foil helps
with high reflectivity and low thermal absorption prevents heat transfer
to the unconditioned basement.
 
Can somebody give me ideas how to model this ? I am using eQUEST 
 
Thanks,
