Commissioning

Independent verification that your building systems are designed, installed, and operating to your requirements. We review the design, test every mode of operation, and track each issue until it is fixed and retested.

Types of commissioning

New construction

From the owner's project requirements and design review through functional testing, turnover, and the warranty review.

ASHRAE Guideline 0, Standard 202

LEED commissioning

Fundamental and Enhanced Commissioning, with the documentation reviewers expect.

LEED v4 and v4.1 EA prerequisite and credit

Retro-commissioning

Existing buildings brought back to how they should run, with findings ranked by impact and cost to fix.

ASHRAE Guideline 0.2

Federal and performance contracts

Commissioning of UESC and ESPC energy measures to federal specifications, including controls integration and cybersecurity coordination.

UFGS 01 91 00.15

Controls and sequences

Sequences of operations written, reviewed, or corrected, then tested point by point through the building automation system.

BAS graphics, trends, and alarms

Diagnostics and TAB review

Root-cause work on pressurization, outdoor air, and hot water problems, plus independent review of balancing reports.

ASHRAE 62.1, AABC and NEBB reports

What is included

Scope is set in the proposal and fits the project. These are the deliverables we typically provide.

  • Design and submittal review comments
  • Sequence of operations review
  • Pre-functional checklists
  • Functional test procedures
  • Issues log with status tracking
  • Field reports with photos

  • Training verification
  • Systems manual review
  • Final commissioning report
  • Seasonal testing
  • 10-month warranty review

How a commissioning project runs

  1. Kickoff

    Confirm systems, sampling, schedule, and who signs off.

  2. Design and submittal review

    Comments logged and tracked to response.

  3. Checklists and startup

    Contractors document installation before tests.

  4. Functional testing

    Witnessed on site, every mode, every alarm.

  5. Closeout and warranty

    Final report, training, and the return visit.

Questions about commissioning

When should a commissioning authority come on board?

Ideally during design, so the owner's requirements and design review can prevent problems instead of finding them later. We also join projects already in construction and work from where they are.

Do you test every unit or a sample?

We follow the specification. Where it allows sampling of identical equipment such as fan coils or VRF indoor units, the sample size and selection rules are written into the commissioning plan, and failures expand the sample.

Can parts of the work be done remotely?

Trend reviews, BAS graphics checks, and document reviews can be remote, which cuts travel. Functional tests are witnessed on site.

Do you commission electrical and plumbing systems?

We commission HVAC, controls, domestic hot water, and lighting controls, and coordinate with the electrical engineer of record on the systems in your specification. Tell us your scope and we will confirm coverage in the proposal.

What do you need to send a proposal?

Building type and size, location, project stage, the systems involved, and the schedule. Mechanical, electrical, plumbing, and controls drawings, the commissioning specification (often Division 01 91 00 or 23 08 00), and a LEED scorecard help us price it precisely.

Need a commissioning authority?

Send the commissioning specification section and drawings, or describe the systems. We reply within one business day.
