[TRNSYS-users] low energy consumption buildings

[Enertech]

Dear TRNSYS Users,

I would like to have an expert advice from TYPE 56 users and developers. 
Thermal transfers trough walls are based on the Transfer Function Method 
developed by Mitalas (cf. TRNSYS Manual, volume 6, § 2.1.6). What are the 
limits of this method ? Is it suitable for very high insulated walls (for 
example 20 cm of polystyrene over 16 cm of concrete) ?

Context of my question : In France, we are working on two big projects of 
very low energy consumption buildings. We prescribe the use of dynamic 
simulation as a conception tool because it’s a very useful tool to estimate 
heating energy consumption and summer comfort. We’re hearing some critics 
about TRNSYS, some says it is not suitable to these kind of buildings. So, 
we would like to be sure of our software.

Thanks a lot,
Christophe.
