Dear Marcus.....
Greetings...
In one of our project , we have CHP which fall under Case 1 as given in LEED Guide, CHP under Same Ownership..We have 2 nos of 500 KW Gas Generator which supplies exhaust heat to VAM Chiller [exhaust driven]-132 TR capacity. Cooling from VAM Chiller is 100% utilized LEED project building only. The power generation from Gas Generator is untilized by LEED Project Building and another building in same campus with connected load of 900 kW and 200KW respectively.
In this scenario. LEED Project is building has 900 KW Connected Load only with average operating Load of 750 KW only. The Same is considered in Proposed Case. And the other building connected load is not included in Energy Simulation as it is non LEED scope Building. WIth This the LEED project building CHP supplies power to other building. is it acceptable by LEED?
Can we Proceed Energy Simulation excluding the power generated for the Non LEED Building????
Thanks in Advance

Samy, Marcus and others volunteer a huge amount of time on this forum. Please be patient—you may not get an answer within hours or days. If a question does not get answered, please consider simplifying it or doing more research on your own.Also please understand that experts like Marcus are often hired as consultants on LEED projects. Many projects would benefit from hiring a dedicated energy consultant, as complicated questions come up that are beyond the scope of what a generalist can answer.

Certainly the more complex the question, the longer it takes to do the research necessary to reply. While we have most of this stuff memorized we don't have it all memorized.
I am reminded of a saying - good, fast, cheap - pick two. Since I don't compromise on at least good advice and it's free hopefully you can understand why it might not be fast.
I will try to get to this one later today.

The short answers to your questions are yes and yes.
The chilled water is considered free.
The gas input to the CHP is all included in the Proposed Case. The electricity going to the LEED project is then free. The gas input used to produce the electricity going to the non-LEED project is included in the Baseline as a process load. See page 267 in the Reference Guide.

Hi all,
Is there any official guidance on whether transformer losses within the building post meter should be included in the receptacle/process load for LEED as metered energy consumption (E.g. 3% of transformer added onto bottom line) or just treated as a heat gain to the space?
Thanks
Victoria
