During the holiday season, many commercial buildings experience extended periods of low or no occupancy. Offices close, tenants travel, and operations slow down, but without the right control strategies in place, building systems often continue running as if nothing has changed.
A Building Automation System (BAS) provides the tools to align your building’s energy use with its actual holiday needs. By strategically reducing HVAC, lighting, and ventilation loads, facilities can significantly lower costs, minimize waste, and maintain safe building conditions throughout the shutdown period.
The Hidden Energy Cost of Holiday Breaks
Commercial buildings are designed for daily activity, people moving, systems cycling, and equipment running. But when those activities stop, energy consumption often doesn’t. Without updated schedules, buildings continue to operate unnecessarily:
- HVAC systems heat and cool unoccupied zones
- Lighting follows standard weekday patterns
- Ventilation delivers full outside air even when no one is present
- Pumps, fans, and circulation equipment run without demand
During a typical late-December slowdown, this can result in 20–40% avoidable energy usage. A BAS makes it possible to capture those savings while ensuring the building remains protected.
Maintaining Safety and Comfort, Even When the Building Is Empty
A holiday shutdown doesn’t mean turning everything off. Commercial buildings still require foundational environmental controls, especially during winter conditions. A BAS helps maintain:
Freeze Protection
Mechanical rooms, perimeters, and pipe chases must stay above critical temperatures. Automated heating setpoints prevent freezing without heating the entire building.
Humidity and Air Quality Management
Some areas, such as IT suites, storage rooms, and equipment zones, need stable humidity or temperature levels to protect assets.
Security and After-Hours Lighting
BAS-integrated lighting controls ensure exterior and security lighting operate as needed while eliminating unnecessary interior loads.
Critical System Monitoring
Even during shutdown, a BAS provides real-time alarming for:
- Temperature drops
- Equipment failures
- Power issues
- Sensor faults
This ensures facilities teams can respond quickly to winter-related risks.
Optimizing BAS Settings for Holiday Savings
With proper planning, a BAS can shift a building into an efficient “holiday mode.” Key strategies include:
- HVAC Temperature Setbacks
Reducing heating setpoints by even a few degrees can create meaningful savings across large commercial footprints. Because setbacks differ by zone type, the BAS ensures critical areas maintain required temperatures while nonessential spaces scale back.
- Adjusted Ventilation Schedules
Unoccupied buildings do not require full fresh-air intake. By reducing minimum ventilation rates and cycling air handling units, the BAS significantly decreases energy tied to conditioning cold outside air.
- Strategic Lighting Reductions
Lighting schedules can be simplified to support only safety and security needs. Occupancy sensors fill the gaps for limited staff entering the building.
- Equipment Runtime Optimization
Fans, pumps, and circulation systems can be programmed to operate only as needed. This targeted approach prevents waste while keeping essential systems reliable.
- Automated Return-to-Occupied Mode
One of the most valuable features of a BAS is consistency. After the holiday break, normal operations automatically resume, warming or cooling spaces before employees and tenants return.
Using Trend Data to Quantify Savings
A BAS does more than control equipment; its data capabilities allow facility teams to analyze and verify efficiency gains. Trend logs help operators:
- Compare holiday-period energy use to normal operations
- Identify equipment that remained active unexpectedly
- Confirm that setbacks and reduced schedules performed as intended
- Document savings for budgeting, planning, or sustainability reporting
In a typical commercial office building, a well-executed holiday BAS strategy can reduce utility costs by thousands of dollars over just a one- or two-week period.
Planning Now for a More Efficient New Year
The holiday season is an ideal reminder of the value a BAS brings year-round. As organizations prepare for the new year, facility teams can benefit from:
- Reviewing and updating BAS programming
- Replacing outdated sensors or controls
- Adding trending dashboards or analytics
- Coordinating BAS settings with tenant schedules
- Performing sequence and equipment audits
These improvements strengthen system reliability, lower operating costs, and support long-term energy strategies.
