Commissioning and Design Engineering Services That Verify Performance

Know Your Building Systems Are Ready to Perform

GLHN’s commissioning and design engineering services help municipalities, healthcare organizations, educational institutions, facility teams, and public agencies confirm that building systems meet project requirements and support daily operations. Since the 1980s, GLHN’s technically based commissioning team has worked with building users, facilities personnel, designers, and contractors on complex new and existing buildings. Focused design reviews, site observations, functional testing, troubleshooting, and performance documentation help identify issues at a stage when solutions can protect schedules, budgets, comfort, energy use, and long-term reliability. You gain a clear path from commissioning requirement to verified performance.

Commissioning Benefits for Owners, Facility Leaders, & Public Agencies

Cross-Disciplinary Design Engineering Services

GLHN’s commissioning team includes professional mechanical and electrical engineers, architects, certified energy managers, and accredited sustainability professionals. You gain technically informed reviews and testing across connected building systems.

Early Design Reviews

Focused reviews evaluate owner requirements, design intent, controls, equipment selections, ventilation, energy use, and building enclosure performance. Identifying coordination concerns early gives your project team more time to respond.

Functional Performance Testing

GLHN verifies that equipment, controls, lighting, HVAC, electrical systems, plumbing, laboratory ventilation, and other commissioned systems perform according to project requirements. Clear documentation helps your team understand results and track corrections.

Existing Building and Retro-Commissioning

Testing, trend analysis, and troubleshooting help uncover performance issues in occupied facilities. Your team can prioritize improvements that support reliability, comfort, efficiency, and changing operational needs.

Monitoring-Based Commissioning

Ongoing trend analysis and measurement provide greater visibility into system performance over time. Facility teams can identify changing conditions and respond before they grow into larger operational concerns.

Training and Post-Occupancy Support

Operations manuals, staff training, seasonal testing, and post-occupancy optimization help facility personnel understand and manage their systems. Your investment continues creating value after occupancy.

Turn a Commissioning Requirement Into a Clear Path to Performance

Commissioning requirements can surface after design is underway, when schedules, budgets, and stakeholder expectations are already in motion.

Municipalities and public agencies may have formal commissioning requirements tied to contracts, codes, funding, or sustainability goals. Healthcare and education facilities also depend on complex systems that directly affect comfort, safety, energy use, research, patient care, and daily operations. When commissioning enters the conversation late, owners need a team that can quickly define the scope, coordinate participants, and create a practical testing plan.

GLHN’s commissioning and design engineering services bring those pieces together through collaborative reviews, site visits, testing, issue tracking, and communication with the full project team. Early involvement creates more opportunities to influence design and construction decisions. Projects already in progress gain a focused process for resolving open requirements and moving toward documented performance. The result is a building team that understands what was tested, what needs attention, and how systems should operate after occupancy.

Real Projects. Documented Performance. Greater Confidence.

Facility leaders value a commissioning partner who communicates clearly, documents findings, and helps project teams close the loop on complex issues. Client experiences highlight the value of collaborative testing, responsive troubleshooting, prepared facility staff, and systems that support the owner’s operational goals.

Clear Answers About Building Commissioning

Understanding the requirements, timing, and process can help you protect your project and prepare your facility team.

Is commissioning required for every project?
Requirements vary by municipality, public agency, contract, code, funding source, building type, and sustainability goal. GLHN can help you review the applicable requirements and define an appropriate commissioning scope.
When should commissioning begin?
The greatest value often comes from beginning during planning or design, when reviews can influence key decisions. GLHN can also join during construction, occupancy, or the operation of an existing building.
Can GLHN help if commissioning was identified late?
Yes. The team can assess current project status, clarify requirements, identify responsible parties, develop testing procedures, and establish a path toward completion.
Which systems can be commissioned?
Commissioning may include HVAC equipment and controls, electrical systems, emergency power, lighting controls, plumbing, laboratory ventilation, process water, building automation, energy systems, and building enclosures.
What is the difference between new building commissioning and retro-commissioning?
New building commissioning verifies systems during design, construction, and occupancy. Retro-commissioning evaluates existing systems to improve performance, resolve operational issues, and identify energy-saving opportunities.
How is testing coordinated in an occupied facility?
GLHN works with facility leaders, users, and operations personnel to understand schedules and critical functions. Testing plans can be organized around operational priorities and communicated clearly to affected teams.
What happens after functional testing?
Findings are documented and tracked through resolution. Depending on the scope, GLHN may also verify corrections, provide staff training, complete seasonal testing, analyze trends, and support post-occupancy optimization.
