specialized commissioning services

Taitem has a number of specialties and skills not shared by other commissioning providers. Some of our specialties include:

  • Solar PV Systems
  • Renewable Energy Systems
  • Envelope Commissioning
  • Experimental Equipment Commissioning

If you have a project with any of the above, here are some things to make sure your commissioning agent can provide:

Solar PV Systems

  • Typically many PV installers attempt to perform their own testing this is Ok for smaller projects, BUT for LEED compliance a third party commissioning agent is required.
  • Solar PV commissioning requires some specialized tools, knowledge and the right weather conditions. At Taitem we put a Big emphasis on code compliance (safety concerns).
  • Taitem policy is to involve experienced field staff (NABCEP Certified Installers) in the commissioning process, bringing you the combined experience of our commissioning team and solar installation crew.

Renewable Energy Systems


Solar Thermal (and solar preheat)

  • Focus areas include temperatures and connection to the building systems – Some things we like to look for: Freeze and overheat protection (including in the event of pump failure), storage tank sizing and placement in the building (can you even get it in the building?)

Geothermal Heat Pumps

  • Review of design, glycol requirements, pressure drop, well depth (does it exceed 499’?)
  • Taitem has several geothermal heat pump experts and designers on staff

Energy Recovery Ventilation

  • We have recently been finding IAQ issues on some units using desiccant energy recovery wheels. This has become a new part of our testing and inspection criteria

Envelope Commissioning


Early Construction Visits

The commissioning agent must be involved on site much sooner in the process than with conventional commissioning

  • Focus on air leakage, insulation and air sealing application.
  • Installation of windows and doors
  • Envelope Cx can also include rain penetration testing and laboratory testing of mock up structures

Design Reviews

  • Looking for thermal bridging

Special Tools

  • Infrared photography
  • Blower Door testing

Experimental Equipment


Taitem has customized testing plan and procedures to include existing test setup and combine commissioning efforts with ongoing monitoring whenever possible. We are often able to take advantage of built in monitoring sensors and data logging for performance verification
