Hi,
The building is catered by own chiller plant located in the building & building owned DES Cogeneration plant for the space cooling. The electricity for the building is from building owned DES & third party electricity board.
if the whole building is catered by the Cogeneration plant. I can use DES allocation calculator & DES guidance. but in this project the the electricity is from third party & cogenration plant.
How I need to document the above case for LEED EB O&M 2009 EAP1?

Satheesh,
First of all, I assume your question is about EAp2 (not EAp1 as your inquiry's text says).
Two forms of energy are relevant to your question: thermal energy (for space cooling) and electrical energy (general use). USGBC's published guidance for district/campus energy systems is mostly intended to establish requirements for allocating thermal energy, not electricity. Although electricity is important to consider in the cogeneration context, it is secondary to the thermal energy.
Thus, since your building's thermal energy is entirely "Building-Owned" as defined by USGBC, I recommend that you use the standard DES guidance and calculator. You should also clearly explain that the electricity is not solely from a "Building-Owned" source in case the LEED reviewer has questions about that.
As always, if you have significant doubts you should submit a formal CIR.
Good luck.
