Agenda What are we going to discuss today? • • What is the condition of our Cx industry today? What is “Big Data”? How to apply to Ongoing commissioning? When to export BAS Data? How to export BAS Data? Methods to improve BAS Data for Ocx. Products you can use for Ongoing commissioning? Examples of real-time Ongoing commissioning? Cx. ENERGY 2014
Condition of Cx Industry What is our standard of care? • Focus on contract documents. • What did the engineer say it should do? • Worry about if things work right maybe not efficiently. • Most know it is not working right but not how to fix it. • Just trying to get job done and not thinking about what happens after you leave. • Let’s use the BAS and technology to support. Cx. ENERGY 2014
Ocx comparison RCx, OCx and MBCx…. continued savings. *Lawrence Berkeley National Laboratory, June 2009 report ‐ Monitoring‐Based Commissioning: Benchmarking Analysis of 24 UC/CSU/IOU Projects Cx. ENERGY 2014
What is Big Data? Where does this come from? Big Data refers to the growth in the amount of data which can be managed and used to run your business. • More data = greater accuracy • Volume - amount of points and time • Velocity – speed with which this data flows • Variety – multiple formats and types How can we use this for Ocx? Cx. ENERGY 2014
Apply ongoing commissioning OCx How do we do it for each case? ASHRAE: Ongoing Commissioning Process: verify that a project continues to meet current and evolving Owner’s Project Requirements. USGBC: based on Facility Operations and maintenance Plan. Energy Star: • Tracks and maintains benefits from RCx • Keeps building documentation up to date • Keeps staff adequately trained • Cx. ENERGY Identifies new opportunities 2014
Ongoing commissioning OCx References LEED O+M: Ongoing Commissioning: Intent -To use the existing building commissioning process to improve building operations, energy, and resource efficiency. Establish an ongoing commissioning process (plan)…to proactively address operating problems in the systems being commissioned. identify and correcting operational errors and deficiencies Set up as a process not a tool or application Cx. ENERGY 2014
Monitor-Based Cx (MBCx) Another Type of Cx A computerized system is installed: • Installed to set trends and baseline • RCx is done (using system and visual testing) with relationships to baseline defined. • OCx is followed to measure savings and verify operation. Cx. ENERGY 2014
ENERGY STAR PROCESS How can this be used in OCx? • • Benchmark Set Objectives Take Action Repeat Improvement Cx. ENERGY 2014
LEED PROCESS How can this be used in OCx? • • Outline plan Find issues Make Corrections Repeat Process Cx. ENERGY 2014
When to export BAS Data When should you do this? • This should be the first step (before RCx). • This data will help you get a good picture of what the systems are doing when you are not there. • Use this data to build a baseline or existing condition. • This may be a way to document the improvement or set the baseline or outline a fault condition. Cx. ENERGY 2014
How to export BAS Data How do you do this? • • You can use loggers (non-technical). You can set up trend reports (a little better). Integrate the BAS into an overlay system. This data can tie into graphs & charts with limits. • This data can populate graphics (dials) • This data can be used in equations to determine faults or rules. Cx. ENERGY 2014
Fault example What does this mean? Off Hours Operation Fault RTU/SF_STS_RUNTIME tagtimestate 1({{par: variable}}, now() - fromhours(24), now(), (75) Midnight_Phase 0 x=IF(trueforduration(quality({{ac: /<<region. Name>>/<<Name>>/HVAC/<<area. N ame>>/RTU<<unit. Number>>/SF_STS_RUNTIME}})!=192, 600000)) THEN IF ({{ac: /<<region. Name>>/<<Name>>/HVAC/<<area. Name>>/RTU<<unit. Number> >/SF_STS_RUNTIME}} > 64800000) THEN 1 ELSE 0 If actual runtime exceeds our expected or scheduled runtime then we will issue a fault Cx. ENERGY 2014
OCx Approach Different forms of the same Many different ways to get there. All should employ analytics • Building Automation Systems (BAS) • Manual OCx with loggers or other devices • Energy Management Systems (EMS) with Dashboards • Advanced Software Analytics with Fault Detection and Diagnostic (FDD) tools • Onsite Software • Cloud (Saa. S) Solutions Cx. ENERGY 2014
OCx Approach Different analytics and processes • • • Alarms which warn of issues Trending, dashboards and loggers Trend analysis using algorithms Advanced dashboards Fault Detection and Diagnostic (FDD) tools • System set up with rules to monitor and rank performance of operation Cx. ENERGY 2014
Methods to improve BAS data for OCx Methods to do this. • • First you need standardization. Naming and tagging needs set up, tree structure Open systems, LONmarks, BACnet, Modbus, etc. Pull only the information you need. Don’t pull all the information. Information overload. • Set up tagging • Project Haystack • Use a web server or web interface to collect and transmit data. Cx. ENERGY 2014
OCx Products What are some examples? Sorry about the commercialism. Intelligent Retro-commissioning Software as a Service (Saa. S) Fault Detection and Diagnostics Ezenics (Optimized Operational Readiness. TM) – Saa. S with rules KGS Buildings (Clockworks. TM) – Saa. S with fault definition Sky. Foundry (Sky. Spark) – On-site or Saa. S software for your customization ICONICS DGLux Continuous Commissioning (CCx-Texas A&M) Cx. ENERGY 2014
Why use Ocx? What are the benefits? • • Can save 10% - 20% of your energy spend Quick 1 -2 year simple payback. Savings are maintained (unlike other Cx projects) Extends staff resources (staff can manage more systems better) • Simplifies BAS systems and their use and outputs. • Helps with operational issues • Comfort • IAQ • O&M management Cx.

OCx Cost and Software Cost What costs are we looking at? • Ocx costs from around $0. 10/sf to $0. 20/sf (based on scope) Will be dependent on number of pieces of equipment and systems. Size and type of building and number of points. • Packaged SAAS products: Integration – ~$8‐ 15 k for a single building Ongoing Saa. S – ~$0. 05 to $0. 09/SF per year • Non SAAS products: Software license is based on number of points Cx. ENERGY 2014 From Upkeep Energy
Future of the of OCx Where is Cx, RCx, OCx and MBCx going? • All these industries are getting more automated and integrated. • How many Cx reports just sit on the shelf? • How many Cx projects find good results but the operation returns to its original condition months after its completion. • OCx and MBCx will help keep the Cx plan current, visible, and present as the project operation evolves. Cx. ENERGY 2014
Conclusions Take aways • OCx and MBCx are the future • Intelligent Building Integration and getting data from the BAS is the way to go • These solutions offer: • Great immediate results with quick paybacks • Are great efficiency and productivity gains • You need a consultant who knows building systems, knows Intelligent Buildings, know BAS and EEMS software and is a Cx.
