ASHRAE Guideline 36, complicated designer control sequences that might emulate ASHRAE 36 or even packaged Roof Top Units....these devices, these systems don't work by magic though people might think so. So, what is the best way to verify that the Owner, the Designers, the Mechanical Contractor, the Electrical Contractor, the Controls Contractor, and the Cx Provider all understand how the control systems work as shown in the project control submittal with its sequences and the interdependencies in the exact same way? The answer to this question is of course, a controls page turn meeting!
There is a likelihood we have all seen the benefit of construction phase page turns of the control submittals or other technical submittals. While the benefits to having this meeting are large, the most important benefit is communicating in person and making sure that the team is on the same page. This is best conveyed with a face-to-face meeting, seeing people’s eyes of truthfulness, getting actual buy in, and obtaining understanding by all, because people do not always take the same meaning from the same words the same way. Our presentation will provide immediate take aways for owners, designers, and contractors by our dissecting, in an entertaining way, actual control submittals so energy saving measures designed can actually be obtained.

This presentation will focus on chilled water plants that include multiple chillers that support industrial processes and/or campuses of commercial buildings. It is intended to provide techniques for plant design and control strategies (for new or existing plants) that require little added engineering time compared to standard practice but result in significantly reduced life-cycle costs. To demonstrate these energy efficiency concepts, the presentation will utilize research papers and educational documentation provided by ASHRAE, as well as a recent case study of the modifications made to a 32,000 Ton chilled water plant serving a campus in northern Illinois.
