Make the Building Work as Promised — Commissioning Services in Minneapolis
Kestrel tests, verifies, and documents every system before the owner takes the keys — and finds the energy waste in the buildings that never got checked.
The Owner's Engineer in Every Room.
Everyone else on a construction project is paid to finish. Kestrel is paid to be sure. We sit on the owner's side of the table from design review through warranty walk — testing what the contractor installed against what the engineer drew and the owner bought. No equipment to sell, no design to defend, no reason to look away.
- ✓PE-led team, LEED and CxA accredited
- ✓Vendor-neutral — we sell verification, nothing else
- ✓Issue logs that get fixed, not filed
Verification for Every Phase of a Building's Life
From the first design review to the tenth year of operation — pick the phase, we'll bring the checklists.
New Construction Commissioning
Design review, installation checks, functional testing, and turnover documentation for new buildings — deficiencies found before the ribbon, not after the first heat wave.
Retro-Commissioning
Existing buildings drift — schedules creep, sequences break, valves stick. We find the operational waste and tune the building back to design intent, usually with paybacks under two years.
Building Envelope Commissioning
Air barrier testing, water infiltration checks, and thermal imaging that verify the skin performs before the drywall hides the evidence.
Energy Audits & Benchmarking
ASHRAE-level audits and utility benchmarking that rank every efficiency measure by real payback — so capital goes where the math is.
LEED & Code Commissioning
Fundamental and enhanced commissioning for LEED projects, plus the energy-code Cx that Minnesota now requires — documented to pass review the first time.
Monitoring-Based Commissioning
Analytics on your building systems that catch drift as it happens — a dashboard and a quarterly tune instead of a decade of slow decay.
Review. Verify. Test. Hand Over.
Commissioning isn't a punch walk at the end — it starts when the drawings do, and every phase gets cheaper the earlier we're in the room.
Design Review
We read the drawings like an operator — flagging sequences that won't control, access that doesn't exist, and meters that measure nothing.
Installation Verification
Site walks and checklists while walls are still open. A backwards check valve costs nothing to fix in framing and a weekend shutdown to fix in year two.
Functional Testing
Every system exercised through every mode — economizer, failure, freeze protection at 20 below. If it can't pass in October, it won't pass in January.
Turnover & Warranty
Operators trained, documentation delivered, and a 10-month warranty review before the contractor's obligations quietly expire.
Boring Openings Are the Whole Point.
A commissioned building opens quietly. The air is right on the first day, the alarms stay silent, and the operating staff already know every system by hand. The uncommissioned version opens too — then spends two years and a legal file getting to the same place.
- ✓Deficiencies resolved before occupancy, on the contractor's dime
- ✓Operators trained on their systems, not generic slides
- ✓A documented baseline your team can hold the building to
The Buildings That Call Us
The Utility Bill Keeps Climbing
Same building, same tenants, higher bills every year. That's drift — and retro-commissioning usually claws back 10–25% without new equipment.
Find the wasteThe New Building Never Worked Right
Hot floors, cold corners, alarms nobody trusts. The systems were installed — but nobody ever proved they work together.

The checklist says 'commissioning agent' and the schedule says 'yesterday.' We slot into design or construction at any phase.
Check the box properly
Your Building Forgot How It Was Designed.
Ten years of overrides, workarounds, and 'temporary' fixes add up to a building running on folklore. Retro-commissioning reads the original intent, measures what the systems actually do now, and closes the gap — sequence by sequence, with the savings metered, not estimated.
- ✓Typical 10–25% energy savings, payback under two years
- ✓Fixes prioritized by cost — most are labor, not capital
- ✓Savings verified on the utility bill, not in a brochure
What Every Project Gets
Tested, Not Assumed
Every sequence runs through every mode with our engineer watching the equipment, not the front-end graphics. Screens lie; dampers don't.
An Issue Log That Closes
Findings are written to be fixed — system, location, evidence, and the spec section that requires it. We track every item to resolution, not to a spreadsheet graveyard.
Numbers on the Table
Energy findings come with metered baselines and verified savings. When we say the building improved, the utility bill agrees.
Owners Who Got What They Paid For
Kestrel's functional testing caught forty-one deficiencies before turnover — dampers wired backwards, a chiller sequence that would have short-cycled all summer. Opening day was boring, which is exactly what we paid for.
The retro-commissioning study paid for itself in the first winter. Twenty-two percent off our gas bill from scheduling and sequence fixes — no new equipment, no capital request, just a building finally running the way it was designed.
As the architect, I want a commissioning agent who improves the building without relitigating the design. Kestrel's issue log was specific, fair, and fixable — and their envelope testing saved us from a curtain wall callback.
Asked Before Kickoff
When should commissioning start?
Design development — that's when a flagged issue costs a markup instead of a change order. We can join at any phase, but every month earlier saves real money. If construction has already started, start us now; the installation-verification window is the next best entry.
Won't the contractor see you as the enemy?
Good contractors love us. A clear issue log during construction beats a lawsuit after turnover, and our findings come with spec references, not opinions. We're firm about deficiencies and fair about responsibility — that reputation is why GCs shortlist us too.
What does retro-commissioning cost, and what's the payback?
Studies for a typical commercial building run in the low five figures and find savings with paybacks usually under two years. We scope after a utility-bill review and a walkthrough — if we don't think the savings are there, we'll say so before you spend anything.
Do we need new equipment to see savings?
Usually not. Most retro-Cx savings come from schedules, setpoints, sequences, and stuck dampers — operational fixes your own staff or controls contractor can make. Capital recommendations only show up when the math genuinely clears.
How do you price commissioning?
Fixed fee, scoped by system count and phase — not a percentage of construction cost, which rewards bloat. The proposal lists every system, every test, and every site visit, so there's no scope fog at month nine.
LEED requires 'enhanced commissioning.' What's the difference?
Fundamental Cx covers the core testing; enhanced adds design review, envelope options, and the 10-month operations review. We're accredited for both — and we'll tell you honestly which credits are worth chasing for your project.
