Orlando is one of the fastest-growing commercial construction markets in the country. Healthcare campuses, entertainment facilities, mixed-use developments, government buildings, and educational institutions are being built and renovated across Central Florida at a pace that shows no sign of slowing.
With that growth comes complexity, and complexity demands verification. Building commissioning is the process that confirms every system in a new or renovated commercial building is installed correctly, operating as designed, and ready to perform for the people who will occupy it.
If you are a general contractor, mechanical engineer, building owner, or facility manager working on a project in the Orlando area, this guide covers what you need to know about building commissioning services and why the firm you choose matters.
What Is Building Commissioning?
Building commissioning (Cx) is a structured quality assurance process that verifies all building systems, HVAC, electrical, plumbing, lighting controls, building automation, and more — are installed and functioning per the owner’s project requirements (OPR) and the engineer’s design intent.
It is not a final inspection. Inspections confirm code compliance. Commissioning confirms performance. The two are not the same, and passing a mechanical inspection does not mean your HVAC system will deliver the airflow, temperature, and humidity your building requires.
Building commissioning also differs from HVAC testing and balancing (TAB), though the two frequently work together. TAB adjusts airflow and pressure throughout the duct system to match design values. Commissioning is the broader process that verifies all system controls, sequences of operation, and integration between systems are working as the engineer intended.
Why Orlando Commercial Projects Require Commissioning
Orlando’s climate creates specific performance demands that make commissioning particularly important. The combination of high outdoor humidity, aggressive solar loads, and nearly year-round cooling creates conditions where improperly commissioned HVAC systems fail in ways that are both uncomfortable and expensive.
A system that was not properly commissioned might cool adequately in mild weather but struggle under peak summer loads. Dehumidification sequences that are not properly verified can allow moisture levels to climb in occupied spaces, leading to mold risk, IAQ complaints, and potential liability for building owners.
Beyond climate, Orlando’s commercial construction market includes a significant volume of healthcare facilities, which carry strict ventilation and pressurization requirements under Florida’s healthcare facility licensing standards. These facilities require independent commissioning as both a performance necessity and a regulatory obligation. Entertainment, hospitality, and mixed-use projects face their own performance demands around occupant comfort, energy consumption, and system reliability.
ASHRAE 90.1, Florida’s energy code, and LEED certification requirements all include commissioning mandates that apply to a broad range of commercial project types in the Orlando market.
Who Needs Building Commissioning Services in Orlando?
Building commissioning services are required or strongly recommended for a wide range of project types in the Orlando area:
- New commercial construction projects above applicable square footage thresholds under Florida’s energy code
- Healthcare facilities, including hospitals, surgery centers, and medical office buildings
- Educational facilities, including K-12 schools and university buildings
- Government and municipal buildings subject to public procurement standards
- Hospitality and entertainment facilities with complex HVAC zoning and occupancy variation
- Projects pursuing LEED or FGBC green building certification
- Renovation and retrofit projects involving significant modifications to existing mechanical systems
If you are unsure whether your project requires commissioning, the answer is almost always yes, and starting early is almost always less expensive than discovering that requirement at substantial completion.
What the Commissioning Process Looks Like
A full commissioning scope for an Orlando commercial project follows a structured sequence that runs from design through occupancy. Here is what each phase involves:
Pre-Design and Design Phase
The commissioning agent reviews the owner’s project requirements and design documents before construction begins. This early review catches coordination issues, sequence gaps, and design deficiencies that are far less expensive to fix on paper than in the field. For projects with complex HVAC systems or tight energy performance requirements, this phase is where commissioning delivers its highest return on investment.
Construction Phase
During construction, the commissioning agent conducts regular site visits to observe equipment installation, review submittals and startup documentation from equipment manufacturers, and verify that systems are being installed in accordance with design drawings. Deficiencies identified during construction are addressed under the construction contract at the most cost-effective time to make corrections.
Functional Performance Testing
This is the core of the commissioning process. The commissioning agent tests each system through its full range of operating sequences, including cooling mode, heating mode, economizer operation, fire alarm integration, unoccupied setback, and more. Every test is documented. Every deficiency is logged and tracked until corrected. Systems must pass functional testing before the project can be considered commissioned.
Documentation and Reporting
The commissioning report documents all testing, all deficiencies identified, all corrections made, and final system performance data. This report is the permanent record that satisfies code, certification, and owner requirements and gives facility managers a reliable baseline for future diagnostics.
Post-Occupancy Follow-Up
For projects requiring full commissioning, follow-up visits occur after the building is occupied to verify that systems continue to perform correctly under real-world conditions. This phase is particularly valuable for buildings with variable occupancy patterns or complex HVAC sequences.
New Building Commissioning vs. Retro-Commissioning in Orlando
New building commissioning is integrated into the construction process and is typically driven by code requirements, certification goals, or owner standards. Retro-commissioning (RCx) applies the same verification process to existing buildings that are underperforming, experiencing comfort complaints, rising energy costs, or equipment issues that standard maintenance has not resolved.
Orlando’s commercial building stock includes a significant inventory of facilities built before modern energy codes and commissioning standards were in place. Retro-commissioning these buildings frequently uncovers control drift, deferred maintenance, and sequence problems that have been quietly inflating energy costs for years.
Research from Lawrence Berkeley National Laboratory consistently shows that retro-commissioning delivers energy savings that pay back the cost of the engagement in less than two years on most commercial projects. SITA provides both new building commissioning and retro-commissioning services across the Orlando metro and broader Central Florida region.
Why Independent Commissioning Matters
The commissioning agent must be independent of the mechanical contractor whose work is being verified. This is not a preference; it is fundamental to the integrity of the process. A commissioning agent with a financial relationship to the installing contractor cannot provide objective results, and commissioning reports from non-independent firms are increasingly rejected by code authorities, certification bodies, and sophisticated building owners.
ACG (Associated Commissioning Group) and AABC both require independence as a condition of their commissioning certification standards. When selecting a commissioning firm for an Orlando project, verify that the firm holds recognized credentials and has no financial connection to the construction team whose work they are verifying.

Frequently Asked Questions About Building Commissioning in Orlando
Is building commissioning required for commercial projects in Orlando?
For many project types, yes. Florida’s energy code, which aligns with ASHRAE 90.1, includes commissioning requirements for commercial buildings above certain thresholds. Healthcare facilities, government buildings, and projects pursuing LEED or FGBC certification have additional mandatory commissioning requirements. Orange County and the City of Orlando follow the Florida Building Code, which incorporates these standards. Projects that do not confirm their commissioning requirements early in design often encounter compliance issues at substantial completion that delay the certificate of occupancy.
How do I find a qualified building commissioning firm in Orlando?
Look for firms with recognized third-party credentials, specifically ACG or AABC commissioning certifications, and a verifiable track record of completed projects in your building type. Ask for sample commissioning reports and references from general contractors and building owners who can speak to the firm’s field performance. Verify that the firm is genuinely independent of the mechanical and construction teams on your project. SITA meets all of these criteria and has been serving the Orlando market for over four decades.
How much does building commissioning cost in Florida?
Commissioning fees vary based on project size, system complexity, and the scope of services required. For most commercial projects, commissioning represents a small fraction of total construction cost, typically 0.5% to 1.5% of the mechanical systems cost, while delivering energy savings, warranty cost avoidance, and compliance documentation that far exceed that investment over the life of the building. SITA provides project-specific proposals based on a review of the drawings and scope. Contact us directly for a quote.
Can SITA commission both new construction and existing buildings in Orlando?
Yes. SITA provides new building commissioning for projects under construction and retro-commissioning for existing facilities experiencing performance issues. Both services follow the same core principles of independent, documented, third-party verification. For existing buildings, retro-commissioning often identifies years of accumulated control drift, deferred maintenance, and sequence problems that standard facility management has not caught, delivering measurable improvements in comfort and energy performance.
