Most people have never seen this tool used on site.

It's how we prove a building performs exactly as designed, not just how it looks on paper.

The Tool Nobody Notices

Here is a mistake we see on commercial builds that costs owners tens of thousands in wasted energy and early equipment failure. đź’¨

It comes down to static pressure. The resistance your HVAC system pushes against every time it moves air through ducts, filters, and equipment.

When the ductwork is undersized for the volume of air being pushed through, the system works twice as hard to deliver what the space needs. That means higher amp draw, faster motor wear, rising energy bills, and spaces that never quite reach comfort.

The worst part? The mistake is usually on the drawings. Signed off. Built to spec. Nobody catches it until the owner is six months in and the utility bill makes no sense.

This is exactly what commissioning and TAB catch. We measure actual static pressure in the field, compare it against design assumptions, and flag undersizing before the building is handed over.

Static pressure is invisible. But it is not optional.

Not sure if your system was sized correctly? Reach out at 813.949.1999.

Anyone can hand you a number. Not everyone can tell you what it means.

Certification and accuracy get you accurate readings. What makes the difference is a team invested in what happens after the report is filed.

That's the partner you're choosing when you choose SITA.

Most building owners do not think about re-commissioning until something is obviously wrong.

By then, the energy waste has been running for years, the comfort complaints have been piling up, and the systems are significantly further from design intent than anyone realized.

Here are 3 signs your building is telling you it needs retro-commissioning, and what it costs to keep ignoring them.

Save this if you manage a commercial or institutional facility.

TAB isn't an expense. It's a return.

Balanced systems use less energy, last longer, and mean fewer comfort complaints down the line, savings that add up well past the invoice.

What we hand you at the end isn't just a comfortable building. It's proof it performs the way it was designed to.

August is National Water Quality Month, and most commercial buildings have water systems running right now that have never been independently verified.

Cooling towers, chilled water loops, and hydronic systems that were commissioned once at startup and never revisited are not the same systems they were at year one.

Here is what that means for your building, and what verification actually confirms.

Save this if you manage a commercial or institutional facility.

We are pushing harder on building commissioning this year, and now we have the team to back it up.

Kevin Boots joined SITA this month as our Building Commissioning Manager. He brings deep field experience in commissioning and steps into this role at exactly the right time as we grow our commissioning work across Central Florida.

If you are specifying commissioning on a project, healthcare, education, commercial, government, Kevin is the person you want on it.

This week is OSHA Safe and Sound Week. Safety is not a program here. It is built into how the work gets done from the first day on site, every project, every time.

A "ready" building and a ready building aren't always the same thing.

VFDs sitting idle instead of in auto are one of the first things that get flagged on a walk-through, long before TAB testing even starts.

What's one thing you always check before calling a system ready?
