I am currently working on a warehouse going for LEED EBOM 2009 certification. The facility is only 5 years old and was built with energy savings in mind and has been maintained well. The facilities manager at the warehouse has been working on making the facility greener and more energy efficient now for the last 4 years. He has implemented many green practices and energy savings techniques and the facility easily meets many of the LEED EBOM requirements.

Is it reasonable to set a performance period that began a year ago and document all the improvements he has made as responses to a "theoretical" energy audit performed at that time?

Otherwise our energy audit would comprise a very short list of possible improvements, and any capital intensive improvements would have a time frame of 5+ years as equipment got older and needed to be phased out...

Thanks!
