[Bldg-sim] Campus CUP Uniform Utility Charges

[David S Eldridge]

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.

Subject: [Bldg-sim] Campus CUP Uniform Utility Charges

 

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?
