Does anyone know how to a one-way slope of a roof in equest?

Hello,

I have a building in my energy model that the roof is sloped one way and
e-quest only allows you to slope a roof either two ways or four ways.
Does anyone know how to fully construct a one way sloping roof using
e-quest? Thanks.

Greetings-
I believe in DD you can select a roof pitch that will tilt in a single plane.

Using either the menue on the left side of the screen, or using the mouse in 3-D view, select the roof. Right click for properties, and input the Tilt. I do not know how eQeust selects with edge to use as a plane of rotation.

You can also input the tilt angle on the spreadsheet.

Good luck.

We are working on a university building that is served by a campus CUP. We created the CHW meter and the Steam meter for purchased heat and cool, but one factor we do not have is the Uniform Energy Charge of the campus CUP.

Below are the eQUEST defaults provided in the help menu. Does anyone know the validity of these numbers or if there are any other LEED approved default numbers?

You'll need to calculate (and provide the documentation) for a
calculated $/unit based on the energy prices and equipment efficiencies
for the project.

Some of the table prices per unit look a little dated. Steam and CHW
unit prices could vary quite a bit depending on your energy cost and
equipment efficiencies. Not that your values can't be these values for
steam and CHW, but you'll have to show how you calculated them. Don't
forget to include the CUP pumping and heat rejection contributions when
providing a purchased CHW rate.
