Ole,
To add to what Jean Marais said, by including the wall capacitance in
the zone and making only resistive walls you are turning Type56 into
something resembling a lumped capacitance model and are no longer
taking advantage of there being any difference between the air
temperature and the surface temperatures. If that is the kind of model
that you want to use then there are some actual lumped capacitance
building models either as a single zone model the standard library
(Type88) or as a multizone model in the TESS Loads and Structures
library (Types 759 and 660)
best,
David

Dear all,
I'm trying to model a building zone in TRNBuild. The store capacity
is specified by 90 Wh/(m²*K). Unfortunately there is no information
about the single store capacities (e.g. walls, furniture,...). Now my
idea was to just model the zone with massless walls and to add the
whole store capacity to the capacity in TRNBuild (normally the wall
capacity is not valued in this parameter). Normally I don't see any
problems regarding to this way of calculation, becauce I only use the
absolute value of the capacity. Do you see any problems in doing this?
Thanks and greets,
Ole
