Learning Objectives
3
1. Attendees will be able to define what analytics and fault detection and diagnostics platforms are and why they are valuable
2. Attendees will be able to describe how to integrate analytics platforms into the traditional NC Cx process
3. Attendees will be able to identify how to leverage automated testing to support the traditional functional testing processes
4. Attendees will be able to define key challenges and solutions to analytics platform integration for NC Cx projects, spanning specification development, to start-ups, to functional testing, and issue resolution.

An automated whole building diagnosticstool is a software program that takes a top-down approach to diagnostics to detect excess energy consumption of the whole building and its major systems…-ASHRAE
Key to Smart Commissioning
Automated Diagnostics at Caltech
2006 2010
• Research Project RP 1455: develop best of class control sequences• Guideline Project Committee: GPC 36 working on providing uniform detailed sequences and associated functional tests to verify proper implementation.
In line with ASHRAE’s current efforts

In the hand-off to warranty, No complaints does not mean the system is optimized.
This approach will find system inefficiency where others will find the job working…
Through continuous testing during the warranty period.

If it’s “too hot” it is too late!
Traditional Cx
• Define the use of automated Cx in project specifications
• Deep coordination needed with controls vendors
• Automated Cx exposes the “copy/paste” nature of controls programming - just “making it work” is not possible with this model
• The process needs to be commissioned…

SMART COMMISSIONING
• Demonstrated potential for future cost reduction through automated testing
• Faster identification of issues – issues log available at Cx Kickoff
• Able to test all labs with the “hit of a button” – retesting was made much simpler
• Significantly reduced field hours for all players
