[TRNSYS-users] greenhouse models

[Michaël Kummert]

Dave,

You may find some information in a paper that was recently presented at 
the "Systems Simulation in Buildings" conference:

E. Mashonjowa, J. G.  Pieters, J. R. Milford1, F. Ronsse, S. Denys, R. 
Lemeur - THE USE OF A TRNSYS BASED DYNAMIC GREENHOUSE CLIMATE  MODEL TO 
SIMULATE THE MICROCLIMATE IN A TYPICAL ZIMBABWEAN GREENHOUSE – in proc. 
of the 7th International Conference on System Simulation in Buildings 
(SSB), Liège, Belgium, December 11-13.

The authors use the so-called "Gembloux Dynamic Greenhouse Climate Model 
(GDGCM)" that was originally written for TRNSYS 13 and was adapted and 
validated in TRNSYS 16. Another reference is:

Pieters J. G. and Deltour J. M. 1997. Performances of greenhouses with 
the presence of condensation on cladding. J. Agric. Engng. Research. 
vol. 68: p. 125-137.

I will send you the first paper off list.

Michaël
