[TRNSYS-users] Regarding modifying the building model to accommodate PCM

[Bachchulal Gupta]

Sir
i have a 225 m2 five zone building model, in order to accommodate the PCM
i attached a new unconditioned zone above the building surface
my problem is that when i change the roof of old building --to the mass
less tile and at the same time i also makes the bottom of unconditioned
zone by mass less tiles and top of unconditioned zone by roof boundary.
(That was the roof of old building)

Now on simulation it requires the large amount of energy because it cant
joint the top (mass less tiles BAND CELING1) and bottom of unconditioned
zone(mass less tiles BAND CEILING2)
i think it assume the mass less tile open to sky

how these can joined or adjacent to each other
i am attaching the model
Regards
