Several years ago I made a good living doing facility energy audits, and after auditing several million square-feet of commercial buildings, I realized that virtually all buildings suffer from the same mistakes: inefficient lighting, outdated controls, poorly maintained equipment, etc. So I took the "recommendations" sections of my reports and wrote a general document for facility managers. I recently updated it, and posted it here. I also made up a checklist for doing energy audits, which is posted here.
I hope you find these documents helpful. Don't be fooled by the recent holiday in energy prices...this is a good oppportunity to get your facility in shape!
