[Bldg-sim] Setback Temperature

[Anderson Letti]

Scott, Nick, Leen and Moore,



Thanks for your feedback. Now I have lots of sources to investigate a bit
more.

Thanks Leen for sharing your PhD research. I’ll have a look at it.



My conclusion so far is that there aren’t specific temperature values for
this situation. It’s basically a matter of design.



Regards,

Anderson Letti
