What you want is a BAS/BMS controls audit or retro-commissioning, rather than just a conventional HVAC inspection. The auditor should review occupied/unoccupied schedules, overrides, setpoints, trend logs, alarms, sensors, and the actual equipment runtime. New Jersey’s retro-commissioning guidance specifically includes aligning zone setpoints with actual operating schedules and correcting controls that operate equipment unnecessarily.

What I'd ask the auditor to do
Tell them: “We have unusually high weekend energy consumption despite the office being unoccupied. We want an independent BAS/BMS scheduling and controls audit.”
Specifically request:
Export of BAS schedules and exception/override schedules.
Review of weekend and holiday calendars.
Trend analysis of HVAC equipment runtime versus occupancy.
Review of after-hours overrides and manual commands.
Verification of occupied/unoccupied heating and cooling setpoints.
Checking whether fans, pumps, AHUs, RTUs, boilers, or chillers are running when they shouldn't.
Sensor and actuator verification.
A written list of programming corrections, estimated savings, and any hardware problems.
I would favor an independent commissioning/retro-commissioning provider if your current HVAC/BMS contractor is the one who programmed the system; Rutgers' New Jersey Green Building Manual specifically recommends a third-party independent commissioning agent for re-commissioning.
If you tell me the BMS brand (e.g., Siemens, Johnson Controls, Trane, Honeywell, Schneider, Tridium) and roughly how large the office is, I can narrow this to the most relevant local firms.
High weekend energy use when a building is vacant almost always points to override loops, misconfigured occupancy schedules, or simultaneous heating/cooling (hunting) in your Building Management System (BMS) or Energy Management System (EMS).
To fix this specific scheduling error, you can turn to several types of professionals depending on whether you need a quick controls fix or a deep engineering investigation:
BMS / Controls Integration Contractors: These are the companies that install and program your specific automation system (e.g., Honeywell, Johnson Controls, Siemens, Schneider Electric local dealers, or independent system integrators). They can dial into your software remotely or on-site to review the time-clock programming, holiday calendars, and zone override permissions.
Retro-Commissioning (RCx) Engineers: If your BMS programming looks correct on paper but equipment is still running, a retro-commissioning firm specializes in identifying operational and maintenance improvements in existing commercial buildings. They test the sequence of operations to ensure components aren't fighting each other over the weekend.
Commercial Energy Auditors: Certified energy auditors (such as those credentialed via ASHRAE standards or independent engineering firms like Coffman Engineers ) can perform a comprehensive review of your interval data logs and building schedules to pinpoint exact phantom loads and control drifts.
Your Local Electric Utility: Many major utility providers offer free or heavily subsidized commercial energy advisory services or retro-commissioning pilot programs specifically aimed at reducing peak demand and off-hours waste.
If you'd like, let me know:
What brand or type of BMS you currently use (if known)
Whether you have an in-house facility team or use an outsourced property management company
I can help you figure out the best first point of contact to get this resolved quickly.
For a BMS/BAS scheduling problem, look for a controls contractor or retro-commissioning/commissioning firm rather than a general HVAC maintenance company. They can review occupied/unoccupied schedules, holiday overrides, HVAC start/stop logic, lighting schedules, setpoints, trends, and actual energy data.
If your office is in Oklahoma City, examples include:
EMCS — specializes in BMS controls, energy monitoring, DDC HVAC controls, and energy audits.
Southwest TAB & Commissioning — provides whole-building commissioning and existing-building system surveys, including performance optimization.
Flux Electric — offers BMS services integrating HVAC, lighting, electrical systems, and energy monitoring for Oklahoma City-area properties.
Trane — its Oklahoma City work has included utility-bill analysis, energy surveys, and BAS scheduling/control optimization.
When requesting the audit, specifically ask for a “BAS/BMS retro-commissioning focused on unoccupied/weekend operation.” Have them trend at least several weeks of Saturday/Sunday operation against weekdays and check whether schedules are being overridden by calendars, occupancy sensors, optimal-start routines, or manual overrides.
If you'd like me to identify local firms that can actually perform this audit, please share your city/area (or enable location sharing).
When high energy bills trace back to empty offices on weekends, you are almost certainly dealing with a scheduling override, a stuck mode (like being locked in "occupied" or "override" status), or a faulty time-clock integration within your Building Management System (BMS) / Building Automation System (BAS).
The specific professionals and entities you can hire to audit and correct these scheduling errors include:
Retro-Commissioning (RCx) Agents / Engineers : These specialists focus explicitly on tuning existing buildings . They dive into your BMS logic, trend logs, and sequences of operation to catch runtime anomalies, phantom overrides, and faulty occupancy schedules. You can look for certified professionals through organizations like the Building Commissioning Association (BCA).
BMS / BAS Integrators and Vendors : The original installer or a third-party programmer for your specific control system brand (e.g., Johnson Controls, Honeywell, Siemens, Schneider Electric) is uniquely equipped to log into the software architecture, review graphic schedules, and fix programming logic errors or corrupted database calendars.
Certified Energy Managers (CEM) / Commercial Energy Auditors : Professionals certified by organizations like the Association of Energy Engineers (AEE) can analyze your interval utility data against your BMS programming to pinpoint where automated setbacks are failing.
In-House Facilities or Property Management Team : If your building leases space or has a dedicated physical plant team, they can often run a quick diagnostic report on the BMS software interface to see if a manual override was left on or if holiday/weekend calendars were improperly configured.
If you'd like, let me know:
The brand or type of BMS you use (if known)
Whether you rent the space or own the building
I can help you figure out the fastest way to approach them or what specific logs to request.

You’ll want a building automation system (BAS/BMS) auditor, controls commissioning agent, or energy engineer with BAS expertise—not just a general electrician or HVAC technician. A good audit should review the BMS schedules, overrides, trend logs, setpoints, sequences of operation, sensors, and equipment run commands to find why systems are operating when the building is empty.
For a weekend energy spike, ask specifically for a “BMS controls audit” or “retro-commissioning review.” They should check for issues such as:
HVAC start/stop schedules running on weekends
Holiday/calendar exceptions that were never updated
Manual overrides left active
Faulty occupancy schedules
Incorrect optimum start/stop settings
Fans, pumps, chillers, or air handlers enabled without demand
Lighting or other automated loads staying on
Sensor errors causing unnecessary heating/cooling
If you’re in the Indianapolis area, some firms that may be relevant to contact include:
Open Control Systems — building automation and energy-management controls services.
CMTA, INC. — engineering and commissioning services that can evaluate building-system performance.
Envelop Group — facilities technology and building automation services.
When you call, you can say something like:
“Our utility bills are highest on weekends when the building is unoccupied. We need a BAS/BMS audit to review schedules, overrides, trends, and sequences of operation to identify unnecessary runtime.”
Before hiring, ask whether they can provide:
A list of BMS points and schedules reviewed
Trend-log analysis showing actual weekend operation
A report separating programming issues from equipment problems
Recommended fixes with estimated energy savings
Verification after changes are made
If you tell me your city, building type (office size), and BMS brand (for example Siemens, Johnson Controls, Trane, Honeywell, Schneider, etc.), I can help narrow the best type of vendor to call.
High weekend energy usage is a classic sign of scheduling overrides, stuck occupancy sensors, or 24/7 default loops hiding in your Building Management System (BMS) or Building Automation System (BAS).
To audit and correct these scheduling errors, you can turn to several types of specialized professionals:
Retro-Commissioning (RCx) Agents: These specialists focus explicitly on optimizing existing mechanical equipment and digital control systems. They specialize in pulling trend logs, finding hidden scheduling conflicts, and re-tuning sequences of operation. You can search for qualified experts through the Building Commissioning Association directory.
BMS/BAS Integrators or Controls Contractors: The original vendor or a third-party controls contractor (representing brands like Johnson Controls, Siemens, Honeywell, or Schneider Electric) can perform a deep-dive software audit. They have direct system-level access to check global schedules, calendar exceptions, and forgotten manual overrides.
Energy Service Companies (ESCOs): If you suspect the scheduling error is part of a broader efficiency problem, an ESCO can perform a comprehensive commercial energy audit. Many ESCOs offer performance-based contracts where their fee is offset by the immediate utility savings they uncover.
Certified Energy Managers (CEMs): Professionals certified by the Association of Energy Engineers (AEE) can analyze your interval utility data against your BMS programming to pinpoint exact hours where base loads spike unnecessarily.
If you'd like, let me know:
What BMS platform or software your building uses (if known)
Whether your utility provider offers interval data (15-minute or hourly usage graphs)
I can give you a better idea of what specific trend logs to pull before calling a professional.

Yes. What you want is a building automation/BMS retro-commissioning specialist, rather than a general energy auditor. They can examine schedules, overrides, occupancy settings, equipment runtimes, and trend data to determine why HVAC or other systems are running on weekends.
Since you’re in the Aurora/Chicagoland area, a few nearby options are:
Applied Controls, LLC — Warrenville. Their published services specifically include system recommissioning, including checking scheduling, user access, alarms, and control functionality.
Big Industries, Inc. — Aurora; local automation company worth contacting for a BMS/controls assessment.
If your building is in Ameren Illinois territory, its energy-efficiency program offers Monitoring-Based Commissioning and a free Virtual Commissioning service. The latter specifically looks for improperly scheduled equipment, startup/shutdown issues, and unnecessary setbacks.
When you call a contractor, I'd ask for a “BMS schedule and controls audit/retro-commissioning” and specifically request:
Review of weekday vs. weekend schedules
Holiday/exception calendars
Manual overrides and forced points
HVAC equipment runtime trends
Occupancy/setback settings
Simultaneous heating/cooling
Trend logs for at least several weekends
A before/after estimate of energy savings
If you tell me the size/type of your building and which BMS you have (e.g., Trane, Siemens, Johnson Controls, Honeywell, Schneider), I can narrow this to the best 2–3 firms for your situation.
High weekend energy use usually points to phantom loads, override switches left on, or a corrupted occupancy schedule in your Building Management System (BMS) or Building Automation System (BAS).
To fix scheduling and control logic errors like this, you need specific professionals who specialize in building optimization rather than a standard lighting or insulation audit.
Professionals Who Can Audit Your BMS
Retro-Commissioning (RCx) Agents / Engineers: These are specialized commissioning authorities who systematically evaluate existing building systems. They specifically look for programming flaws, control loop tuning issues, and bad override schedules causing equipment to run 24/7. You can search for certified professionals via the Building Commissioning Association (BCA).
BMS / BAS Integration and Controls Contractors: The original installers or a competing local controls vendor (representing platforms like Johnson Controls, Honeywell, Siemens, or Schneider Electric) can perform a deep-dive software audit. They will review your occupancy templates, holiday overrides, and zone scheduling logic.
Energy Services Companies (ESCOs): If the scheduling error is part of a broader inefficiency profile, an ESCO can perform an ASHRAE Level II Energy Audit and often bundle the BMS reprogramming into a performance contract where savings pay for the service.
Your Local Electric/Gas Utility's Commercial Account Rep: Many utilities offer free or heavily subsidized retro-commissioning or retro-tuning programs specifically designed to find ghost loads and scheduling anomalies in commercial buildings.
If you share your general location (city/state) and approximate building size or utility provider , I can help you find local utility rebate programs or specific contractor networks in your area.
High weekend energy use when a building is vacant usually points to a classic Building Management System (BMS) or Building Automation System (BAS) override—such as HVAC units stuck in "occupied" mode, holiday schedules overriding normal routines, or optimized start/stop controls malfunctioning.
To fix scheduling and sequence-of-operations errors like this, you need specific types of energy professionals:
Retro-Commissioning (RCx) Agents / Engineers : These specialists focus explicitly on tuning and optimizing existing equipment and digital controls. They specialize in diving into your BMS programming to fix faulty schedules, sensor drift, and phantom loads. You can search for certified professionals through the Building Commissioning Association (BCA).
Certified Energy Managers (CEM) : Credentialed through the Association of Energy Engineers (AEE), a CEM can perform a targeted commercial energy audit to isolate why baseline loads spike during unoccupied hours.
Your BMS/BAS Integration Vendor : If your system was installed or is serviced by a major controls contractor (e.g., Schneider Electric, Johnson Controls, Siemens, Honeywell), their internal application engineers can run a diagnostic audit specifically on your software scheduling logic and occupancy overrides.
Electric Utility Account Managers : Many regional utility companies offer subsidized or free retro-commissioning or retro-audit programs for commercial customers to help reduce peak grid strain. It is worth checking your local provider's commercial rebate and audit portal.
If you'd like, let me know:
What BMS/BAS platform or vendor you currently use
Whether your utility provider offers commercial energy programs in your area
I can help you prepare a specific scope of work or checklist to hand over to an auditor or vendor.
