Kevin,<div><br></div><div>You should read the DES modeling guidelines that Daniel referenced. There are two options on how you choose to model the district utility system. If you choose to model it as a simple purchased steam meter, then you are limited to a maximum amount of points under EAc1. Conversely, if you choose to model the entire steam plant from source to site, you have to show a minimum of 6 points.</div>

I had this issue with a cogeneration project that was inaccurately sized for the demand and resulted in (according to calcs) less efficient operation than the minimum required baseline.

I've inherited an energy model that was done over 3 years ago by someone no longer at our firm.<br>I'm an eQuest novice and have a question about a system that uses campus steam for heating.<br>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)<br>
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?<u></u><u></u></p><div>
