Dear Steve,
about calculated nat vent and cooling design, in the manual I find this statement:
Note 1: for Cooling design simulations, natural ventilation is always handled as Scheduled even wh ... |

Steve I'll try again...but in my opinion something is wrong solar gains are to high whan I'm using shading.
Nevertheless I'll let you know.

Hi Luca,
but we will consider modifying this behaviour, perhaps using an option to link the variables.
this would be perfect...and I think not so heavy on the programming side...I hope!

Hi Steve,
In my first e-mail I was underlining that the program doesn't update "actual lighting casual gain" when the target illuminance of the zone is changed.
So
Note that when you load l ... |

Mahabir,
thank you nevertheless there is a bug. It is true that target illuminance is used for ligtning control but even if this control is off, target illuminance is used to set the Lightning ener ... |

Hi,
I've found this bug: the Lightning energy (in "Lightning-General Lightning") is not updated automatically when the "Target illuminance" in the activity window is changed. This causes a lot of m ... |

Hi,
two problems with roof glazing.
1) Default roof glazing doesn't work, in the attached example (Default_roof_glazing.dsb), I've set 100% at building level and no window appears on the roof

I've tried this, but there is strange. If with a Compact HVAC - CAV I switch on/off the mechanical ventilation (fresh air/no fresh air)...the design latent load changes a lot!
So I would expect that ... |

Dear Steve,
with 1.4.032 version the situation doesn't change
I don't know if you refered to 1-4-033 which is a developer version.
Did you ask E+ developers about it?
