[TRNSYS-users] heat capacitance of furnishings ect.

[David BRADLEY]

Karol,
The general rule of thumb that I use is 5 times the default (which 
accounts only for the thermal capacitance of the air). The formula ends 
up being ZoneVolume*1.2*1.007*5 (1.2 is the density of air, 1.007 is the 
specific heat)
Best,
  David
