[Bldg-sim] District heating and cooling

[Varkie Thomas]

Lixing,
I will be creating a case study that demos central (perhaps cogen) plant with district heating and cooling.   I have done this with DOE2.1E at SOM.  I need to create a generic model (in DOE2.1E and eQUEST) for public distribution.  You can open and look at 3 other case study PDF reports based on real projects from the IIT energy seminar website below.  Attached is a summary of the seminar. There might still be a few seats left.  I now live in Minneapolis.
