[TRNSYS-users] Cooperation between a roof cooling technique and the building

[David Bradley]

Artemi,
  It sounds to me as though you are on the correct track. A very similar 
technique is used by the multi-zone slab-on-grade model that will be 
released with Trnsys17, by the various ground coupling components in the 
TESS Libraries (including a multi-zone basement). The same technique is 
also used in a phase change material (PCM) wall component that was 
developed at the Institute of Thermal Engineering at the University of 
Technology Graz. You can find a link about the PCM component at:

Kind regards,
 David
