[TRNSYS-users] Radiative cooling systems

[WATRINET, Emmanuel]

Hi everyone, hi Jeff, 

I aim to model different radiative cooling systems using TRNSYS 16 (soon TRNSYS 17), to evaluate their potential under French climate and compare their efficiencies. I found on the Internet the following discussion :

I am very interested in getting some details on the model you describe at the end. Is it possible to get more information, any file or document describing it ?

Thank you very much for your time.
Best regards,
