Whether your project is a newly constructed high-rise commercial building or a renovated HVAC and controls system in an academic facility, Plug Smart is your representative and advocate as your commissioning agent.


Commissioning (Cx)


  • Fundamental Commissioning

  • Enhanced Commissioning

  • Ongoing Commissioning

  • Retro Commissioning


Our commissioning engineers and technicians specialize in leading all the commissioning process activities throughout and after construction.


Fundamental Commissioning


During the design and construction  phases of your project, we focus on your project requirements and basis of design for your building’s energy-related systems, working with the design team to ensure that any necessary updates are made to these documents throughout.
As we compile and develop the commissioning requirements for your project, we incorporate them into your construction documents and finalize your project’s commissioning plan.
After your project is complete, we conduct a comprehensive verification process that confirms the installation and performance of energy consuming systems are compliant with your requirements and compile your commissioning report.

Major relevant systems for commissioning include:


  • Heating, ventilating, air conditioning, and refrigeration (HVAC&R) systems (mechanical and passive)

  • Building Automation and Controls

  • Lighting and daylighting controls

  • Domestic hot water systems

  • Renewable energy systems (wind, solar etc.)

  • Security and Access Controls

Enhanced Commissioning

Enhanced Commissioning includes all of the key responsibilities of Fundamental Commissioning and can vary depending on your needs for your project. Typical additions include:


  • Earlier engagement during the design phase to provide review(s) of construction documents prior to 50 percent.

  • Creation or review of contractor submittals

  • Systems manual development

  • Oversight, coordination, and verification of training for your systems-operating personnel

  • Review of your building operations within ten months of substantial completion.


Ongoing Commissioning


In order to ensure that your building and its equipment operate in accordance with the Basis of Design, Ongoing Commissioning is mission critical. This process includes  planning, point monitoring, system testing, performance verification, corrective action response, ongoing measurement, and documentation to address operating problems proactively. Ongoing Commissioning should be performed at least quarterly in the first year and at least once every two years thereafter.


Retro Commissioning


In buildings where either there is a significant amount of  new equipment (replaced HVAC, building controls) systems or where commissioning hasn’t been performed recently, Retro Commissioning can get your building back on track and  performing as designed. Our commissioning and energy energy engineers perform all necessary planning, investigation, analysis, implementation and verification steps to deliver a successful Retro Commissioning initiative, typically with analysis or reanalysis, implementation, and verification steps being performed quarterly for the first 6 to 12 months and set you up for Ongoing Commissioning every two years thereafter.
