Start with the BMS
![Page 10: Continuous Commissioning Insights · CopperTree analytics • Developer of Kaizen Software –Via Setpoint Solutions Ltd - Wellington • Works in conjunction with most BMS systems](https://reader033.fdocuments.us/reader033/viewer/2022050304/5f6cc5006568dd0c6714c87c/html5/thumbnails/10.jpg)
BMS – Initial checks• Is the software up to date?
• Memory can be limited – especially in zone / terminal controllers
• I/O can be added for additional sensors if required (Eg solar)
• Cannot compensate for poor mechanical design - but can disguise it!
• Garbage in = garbage out
• Calibrated sensors, appropriate locations
• Data corruption due to induction and power issues
• Fit a UPS with a good line filter for all BMS controls

The typical CCx process
![Page 12: Continuous Commissioning Insights · CopperTree analytics • Developer of Kaizen Software –Via Setpoint Solutions Ltd - Wellington • Works in conjunction with most BMS systems](https://reader033.fdocuments.us/reader033/viewer/2022050304/5f6cc5006568dd0c6714c87c/html5/thumbnails/12.jpg)
Emergence of BMS data mining…
• Diagnostic & analytic packages

• Proprietary packages developed by BMS companies
• Stand-alone independent packages developed by 3rd parties
• Access real-time as well as stored data within the BMS
• Run diagnostic routines to interrogate the data
• Manage the information collected

Barriers to uptake of CCx
• Lack of awareness of the process by landlords and tenants
• Lack of understanding of the benefits by landlords and tenants
• Unclear as to where additional costs are to be allocated to
• Not promoted by maintenance contractors due to perceived reduction in call-outs / service work
• Lack of formal contracts with BMS companies
• Lack of skills to undertake the work
• Lack of uptake of formal training
![Page 22: Continuous Commissioning Insights · CopperTree analytics • Developer of Kaizen Software –Via Setpoint Solutions Ltd - Wellington • Works in conjunction with most BMS systems](https://reader033.fdocuments.us/reader033/viewer/2022050304/5f6cc5006568dd0c6714c87c/html5/thumbnails/22.jpg)
Cost / Benefit• Who should pay?• Landlord owns the plant and systems• Landlord benefits from extended plant life, deferred capex,
improved tenant retention & increased building value.• Tenant benefits from reduced opex via energy savings, reduced
call-outs & higher staff productivity• CCx can be viewed as an extension to the maintenance services• Additional costs should be more than offset by reduced opex
costs, so logic would suggest CCx is a recoverable tenant cost• It may be a shared landlord tenant cost, as benefits cut both
ways
