Ongoing Commissioning

Making Data Actionable

Today’s automation systems give building operators an abundance of data. Often there is so much data that most building operators only have time to check two or three data points with any regularity. The rest of the data is stored for a 30-day cycle until there is a failure of some kind, and then the service company for that system will look for the data they need to diagnose the issue. It is usually at this point that the owner discovers they aren’t storing the right BAS points or they are storing them at a time interval that makes it virtually worthless for identifying the root cause.

After years of dealing with this issue, Hunton Services began fielding an analytics program that has been developed to comb through the massive amount of BAS points, provide a grade to various systems and components, allow analysts and engineers to dive in deeper, change point sampling rates to something frequent enough to be useful, and ultimately report back to the owner with functional improvements to their system.

According to research from Texas A&M University and the Lawrence Berkeley National Laboratory, the result of operational wear and tear – known as drift – buildings can see energy efficiencies degrade by 10% to 30% over a one- to two-year period.

To prevent this, we implement a process known as Ongoing Commissioning. Instead of allowing a system to drift from proper operation over the course of years, Hunton Services will implement an Ongoing Commissioning plan which utilizes our analytics programs to identify and correct drift. At the same time the system finds new operational improvements that when implemented make each system more efficient, ultimately driving down the operational costs of a building, instead of allowing them to drift up.

Hunton Services can provide Dynamic Commissioning within the following building sub-systems:

• Heating, ventilating, air conditioning, refrigeration and their associated controls systems
• Lighting systems
• Domestic hot water systems
• Plumbing systems
• Building envelope systems
• IT Systems and building networks
