[Equest-users] Daylighting

[Tim Dion]

Shut down, went to lunch, started up again after lunch and reran. 

Went away. Results as expected now. Sorry to bother everyone.

No -- not to be unhelpful but that is both counter-intuitive and not what I've seen in turning daylighting on and off in parametric runs.  As expected I've seen lighting go down, heating go up and cooling go down when daylighting is turned on.

Sorry.
