[Equest-users] eQuest - Campus Steam

Hi Daniel, 

Thanks for the reply on the LEED requirements. You confirm an issue with having a campus system in that it can limit the potential energy points, but that is another topic... 

What I'm not familiar with is how to change the "on-site" boilers that were modeled with a campus steam supply (I have been given a cost per lb of steam by the university), a steam to water heat exchanger and pumps. If anyone can walk me through this or point me in the right direction, I would appreciate that. 

Thanks for any help,

Hi Jim, 

Just FYI if this is a LEED model you should check out the District Energy Modelling Requirements from the USGBC ( http://www.usgbc.org/ShowFile.aspx?DocumentID=7671 ). By modelling as purchased steam you are limiting the number of EAc1 points available.

I've inherited an energy model that was done over 3 years ago by someone no longer at our firm. 
I'm an eQuest novice and have a question about a system that uses campus steam for heating. 
The original model was set up with two gas fired boilers. (I see this in the Component Tree tab in the Water-Side HVAC section) 
How do I tell eQuest that the heating is from a campus/purchased steam system so that it complies with ASHRAE 90.1-2004 item G3.1.1.1, Purchased Heat which requires the campus utility rate to be used?
