4 TRADITIONAL COMMISSIONING DESIGN & CONSTRUCTION Cx Project Handoff OPERATIONS RCx Warranty Period VS. SMART COMMISSIONING DESIGN & CONSTRUCTION Project Transition Cx Cx Warranty Period Period OPERATIONS RCx m

5 Traditional vs. Smart Commissioning Goals: Prove the potential for future Cx cost savings Reduce the issue correction time Run functional tests simultaneously Improve data flow and improve Cx quality Establish baselines and reduce future O/M Costs Warranty period supported by Smart Cx Everything gets tested m

6 Traditional functional testing Traditional Commissioning OPR Review BOD Review Peer Review Submittal Review Pre-Functional Tests Functional Performance Test Scripts Functional Performance Test Develop Tests Demonstration Tests Punch list Back Check and Verification Systems Manual Warranty Review Continuous Alarming Ongoing Commissioning Future Retro-Commissioning g

8 Now repeat over and over and over... Meanwhile Owner wants to move in MEP punch items being resolved Cx & Controls teams is trying to Make it Work RESULT: likely Cx result is sub-optimized g

9 Key to Smart Commissioning An automated whole building diagnostics tool 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 G-J

10 Automated Diagnostics at Caltech m

11 Standardizing control sequences m

12 Standardization of Controls Sequences Standardization of Control Sequences In line with ASHRAE s current efforts 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. g

14 Case Study: Caltech Beckman Institute Retrofitting 27 labs from analog to digital controls m

15 ata points Occupancy Fume Hood Flow Reheat Control Exhaust Momentum Pressure Offset Sash Position Supply Temperature Bypass Air General Exhaust Flow 111 Data Points in each lab j

16 Data Points start in building controls and multiply with each branch j

18 What s different about smart commissioning Traditional Commissioning OPR Review BOD Review Peer Review Submittal Review Pre-Functional Tests Functional Performance Test Scripts Functional Performance Test Demonstration Tests Punch list Back Check and Verification Systems Manual Warranty Review Continuous Alarming Ongoing Commissioning Future Retro-Commissioning Smart Commissioning OPR Review BOD Review Peer Review Submittal Review Pre-Functional Tests Functional Performance Test Scripts Functional Performance Test Demonstration Tests Punch List Back Check and Verification Systems Manual Warranty Review Continuous Alarming Ongoing Commissioning Future Retro-Commissioning? G-J

19 Smart Commissioning Translating traditional functional performance tests Running automated process; no longer self performed by installing contractors Automated diagnostics sent to controls contractor for correction Enhancing the traditional model Making Data Work Smart Commissioning OPR Review BOD Review Peer Review Submittal Review Pre-Functional Tests Functional Performance Test Scripts Functional Performance Test Demonstration Tests Punch List Back Check and Verification Systems Manual Warranty Review Integrated Continuous Workspace Alarming Management Ongoing Commissioning Future Retro-Commissioning? G1-J4

20 1 Translating traditional functional performance tests TRADITIONAL SCRIPTS WITH STEP BY STEP TESTS SET OF CONDITIONS SET OF RULES FIELD VERIFICATION? G-J

21 1 Translating traditional functional performance tests Automated Cx requires all the points to be named consistently or tagged with a searchable convention Building-NN-AHU-X-FLOOR-##VAV-Y-DAT(F) OR Building-NN-AHU-X-FLOOR-##VAV-Z-Supply Air Temp(F) #ERROR- CANNOT FIND DATA J

22 2 Running automated process The Rules need to be commissioned J

23 3 Automated diagnostics sent to controls contractor for correction J-G

24 4 Enhancing the traditional model 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. M-G

25 J-m 5 Making Data Work Traditional Cx Smart Cx If it s too hot it is too late!

26 What we learned It took 4 DAYS to tune the process Define the use of automated Cx in project specifications 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 Project Transition DESIGN & CONSTRUCTION Cx Cx OPERATIONS RCx Warranty Period J-g

27 How we did on the goals
