This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

One presentation describes the faulty performance of a private school, three new schools in a suburban school district, and a hospital. In each case the mechanical systems did not operate per the owner's requirements and failed to provide the proper occupancy conditions. The other presentation addresses how energy savings with under a two year payback was accomplished at an airport terminal and what measures were effective through existing building commissioning.
