Hi David, I confirm that our montoring data (18 month in 5 minute step, also available in 1 hour step) would be available for testing of such a greenhouse model. The data concerns 3 identical agricultural greenhouses, of which 2 were equiped with daily heat storage systems (water tank and air/soil heat exchanger).
For the standard greenhouse (without storage), the data concerns : - solar radiation - ambient temperature and humidity - internal temperature and humidity at 1 and 2 m height - temperature of internal shading device - soil temperature at 40 and 70 cm depth - auxiliary heating - humidification system - opening of windows and activation of shading device A detailed report can be found on: www.unige.ch/cuepe/html/biblio/detail.php?id=20 It is in French, but going quickly through the figures will give you an idea of what was done and what is available (see in particular annex 1) Best regards Pierre PS : let me know if you develop such a greenhouse type.
