We are working on a project that uses heat reclaim as a source of energy for service hot water. Heat is reclaimed from the flue gases of a generator set that is used to complement the utility grid in providing electricity since the utility doesn't provide 24/7 electricity.

How can this reclaimed heat be modeled? And is this considered CHP and to be modeled according to the document titled: "Treatment of District or Campus Thermal Energy in LEED V2 and LEED 2009 – Design & Construction"?
