What guidelines should be used for district thermal energy systems in v4 when using option 1, specifically combined heat and power systems? The credit language does not clarify how it should be modeled and I could not find any guidance documents on USGBC's website. ASHRAE 90.1-2010 has a section on purchased heat but this section was excluded in v2009.

The DES modeling methodology has been incorporated into the Reference Guide for v4 and is now mandatory. It is under Further Explanation - Project Type Variations.
