Who we work for

Each side of a project needs something different from a commissioning or energy engineer. Here is what we bring to yours.

  • Owners and developers

    An advocate who verifies you received the building you paid for, before the warranty clock runs out.

  • General contractors

    A commissioning authority who works your schedule, reviews early, and documents fast so closeout does not stall.

  • Architects and MEP engineers

    A commissioning or energy modeling partner for LEED and owner-required projects, independent of your design.

  • Facility and energy managers

    Retro-commissioning and audits that find the operating problems behind comfort complaints and high utility bills.

  • ESCOs and federal UESC or ESPC teams

    Measure commissioning built to federal specifications, test documentation, and controls cybersecurity requirements.

Services

Three services, each delivered by a licensed engineer who has worked the full life of a building system.

Commissioning

Independent verification that HVAC, controls, plumbing, and lighting control systems are designed, installed, and operating to your requirements. New construction, LEED, retro-commissioning, and commissioning of federal energy measures.

You'll want this when:

  • Your specification or LEED target requires a commissioning authority
  • A new building is approaching turnover and nothing has been tested yet
  • An existing building has comfort complaints or alarms no one can explain
  • A UESC or ESPC energy measure needs commissioning to federal specifications

Energy audits

ASHRAE Level 1, 2, and 3 energy audits that turn utility data and field findings into a ranked list of measures, each with cost, savings, and payback.

You'll want this when:

  • A local benchmarking or audit ordinance applies to your building
  • Utility costs are rising and the cause is not obvious
  • You are planning capital work and want energy measures in the same budget
  • You need a defensible basis for an incentive or financing application

Energy modeling

Whole-building energy models for LEED energy credits, energy code performance compliance, and design decisions, built by an ASHRAE-certified Building Energy Modeling Professional.

You'll want this when:

  • Your LEED project needs Optimize Energy Performance documentation
  • The design team is choosing between HVAC systems, glazing, or envelope options
  • Your project is taking the performance path under the energy code
  • You want to know a design's operating cost before it is built

From design review to the warranty walk

We have done every step of the commissioning process, so we can join your project at any one of them.

  1. Owner's requirements

    Write down what the building has to do, in terms that can be tested.

  2. Design review

    Comment on drawings and specifications while changes are still cheap.

  3. Sequences of operations

    Review or write the control logic each system will be tested against.

  4. Commissioning plan

    Roles, schedule, systems, sampling, and test methods agreed up front.

  5. Submittal review

    Check equipment and controls submittals against design intent.

  6. Pre-functional checklists

    Contractors verify installation and startup before testing begins.

  7. Functional testing

    Run each system through every mode it will see in operation.

  8. Issue resolution

    Track every finding to a fix and a passed retest.

  9. Training and systems manual

    Hand operators a building they understand and can maintain.

  10. Seasonal and warranty review

    Return for opposite-season tests and a walk before the warranty ends.

Selected projects

Hospitals, research buildings, hotels, and federal facilities. What we found matters more than the list of tasks.

Military installation, Pacific Northwest

Steam decentralization and barracks HVAC under a utility energy service contract

Commissioning authority for two energy conservation measures: replacing a central steam loop with building-level boiler plants across eight buildings, and a full HVAC replacement in a barracks with dedicated outdoor air units, fan coils, an air-cooled chiller, and a condensing boiler.

Design review caught a boiler efficiency deviation from the contract, a removed system still in the test scope, and a controls protocol conflict before construction started.

Acute care hospital, Florida

Pharmacy suite pressurization

Testing found the pharmacy's main area negative to the corridor and the ante room negative to the main area, where both needed to be positive.

Testing at increased outdoor air showed the serving air handler could not reach its discharge air temperature target, so the fix had to include the unit, not just the room balance.

Building automation issues log

Built a formal commissioning issues log from a review of 73 building automation system screens.

Captured 44 issues and ranked each by priority so the team could fix the highest-impact items first.

Why teams bring us in

Independent

We are not tied to a designer, contractor, controls vendor, or manufacturer. Findings go to you as written, with the evidence attached.

Principal-led

The engineer who scopes your proposal is the one who reviews the design, runs the tests, and signs the report. No hand-off to junior staff.

Issues that get closed

Every finding states what was observed, why it matters, who owns it, and what done looks like. Then we retest it.

Nationwide

Projects on both coasts and in between. Travel is scoped up front, and remote trend and BAS review keeps site visits to the ones that count.

Common questions

Do you work outside Florida?

Yes. We commission and model buildings across the United States, on both coasts and in between. Work that requires a professional engineer's seal is limited to states where our engineer is licensed, currently Florida and California.

Can you propose on a project that is already out for bid?

Yes. Send the RFP, the commissioning specification section, and the drawings or a link to them. We reply within one business day and can turn around a proposal on bid-day schedules.

How are fees structured?

Most commissioning, audit, and modeling work is a fixed fee based on the systems in scope, the number of site visits, and the deliverables. Diagnostic work on an existing problem can be hourly with a not-to-exceed amount.

Are you independent of the design and construction team?

Yes. We are not affiliated with any designer, contractor, controls vendor, or equipment manufacturer. Our findings go to the owner as written.

Have a project out for bid?

Send the RFP, drawings, or a few lines about the building. We reply within one business day and tell you plainly whether we are a fit to propose.
