[Equest-users] Translucent Glass Overhangs?

[Keith Swartz]

Neil,

You can enter a transmittance for the shade if it is entered as a "Building Shade" or a "Fixed Shade," but not if it's entered as a "Window Shade."

In detailed edit mode, in the "Building Shell" module, right-click on "Building Shade" (or "Fixed  Shade") to create a new one. See the help screens and tutorials for an explanation of the dimensions and coordinates. The field for the transmittance is on the right side. So is visible reflectance, which can affect glare. You could also create a schedule to change the transmittance for when it might be covered with snow, leaves, or whatever. On a side note, this method using a schedule could also be used to model a deciduous tree that shades during the summer but not in the winter.

Subject: [Equest-users] Translucent Glass Overhangs?

Hi everyone,

I have a building with frosted glass overhangs that are fairly large, about 10 feet out. I am only concerned with the energy component of my model and do not have any daylighting controls so this should make things easier. My gut tells me the frosted overhang will reduce and potentially eliminate the direct solar heat gain component. Has anyone studied this?

Thanks,

Neil Bulger

Pranita,
Could you create a secondary loop for each chiller? You could then get the numbers you need from the PS-D or PS-H report.

Subject: [Equest-users] Calculate energy usage of individual buildings in a campus

Hello All -

I am modelling a campus in eQuest which has 7 building. All building are connected to the central chiller and boiler. I am trying to figure out how much of the chiller capacity each building is using from the chiller and how much of the boiler capacity each building is using.

Which reports in eQuest give this breakdown of eneryg usage? OR Do we have to calculate these number, if so please give a brief explanation.

Thank You.
