TL;DR
- Not all electrical equipment presents the same level of risk.
- Critical infrastructure should receive the highest inspection priority.
- Main switchboards, transformers, automatic transfer switches, and motor control equipment often have the greatest impact on hotel operations.
- Hotels frequently focus on guest-facing issues while overlooking electrical equipment that supports the entire facility.
- A risk-based infrared inspection program helps engineering teams prioritize the equipment that matters most.
Where Should Hotels Focus Their Infrared Inspections?
One of the most common questions from Directors of Engineering is:
“What equipment should we actually inspect?”
The answer depends on the size and complexity of the property, but most hotels benefit from prioritizing equipment based on operational impact.
If a piece of equipment fails, ask yourself:
Would this affect guest comfort, life safety, revenue, or building operations?
If the answer is yes, it should likely be included in your infrared inspection program.
The goal is not necessarily to inspect everything first.
The goal is to identify the equipment most likely to create significant operational problems if a failure occurs.
Priority 1: Critical Infrastructure
These are the electrical systems that can significantly impact hotel operations if they fail.
Main Switchboards
Main switchboards are often the heart of a hotel’s electrical distribution system.
A loose connection, overloaded breaker, or deteriorating component within a main switchboard can affect large portions of the property.
Infrared inspections frequently identify:
- Loose electrical connections
- Overheated breakers
- Unbalanced loads
- High resistance connections
- Deteriorating components
Because of their importance, main switchboards are often among the highest-priority assets during a thermographic survey.
Emergency Generators
Hotels rely on emergency power systems to support critical operations during utility outages.
While generators themselves are important, the associated electrical connections, breakers, and distribution equipment should also be included in routine inspections.
Potential issues may remain hidden until the generator is called upon during an actual emergency.
Automatic Transfer Switches (ATS)
Automatic transfer switches play a critical role in moving electrical loads from utility power to generator power.
Because they may remain inactive for long periods of time, developing problems can go unnoticed.
An ATS failure during an outage can significantly affect emergency power reliability.
Fire Pump Systems
Fire pump equipment is directly tied to life safety.
Electrical deficiencies affecting fire pump controllers, disconnects, or associated equipment should be identified and corrected before they become operational concerns.
Priority 2: Operational Equipment
These systems may not impact the entire property, but they can significantly affect guest experience and hotel operations.
HVAC Equipment
Guests may not notice a healthy HVAC system.
They immediately notice one that isn’t working.
Motor control centers, HVAC distribution equipment, chillers, cooling towers, and associated electrical panels often experience significant loading and should be routinely evaluated.
Motor Control Centers (MCCs)
Motor control centers support many of the systems that keep a hotel functioning.
These can include:
- Chilled water systems
- Booster pumps
- Exhaust fans
- Cooling towers
- Mechanical equipment
A single electrical issue within an MCC can affect multiple building systems simultaneously.
Kitchen and Restaurant Equipment
Restaurants, banquet facilities, and commercial kitchens often contain heavily loaded electrical equipment.
Infrared inspections can help identify developing issues before they affect food service operations or create unexpected downtime.
Laundry Facilities
Many hotels rely heavily on in-house laundry operations.
Electrical failures affecting laundry equipment can quickly create operational challenges, particularly during periods of high occupancy.
Priority 3: Guest Service Equipment
These systems may not impact the entire facility but still contribute to guest satisfaction and overall operations.
Guest Room Distribution Panels
Guest room panels generally represent a lower operational risk than main distribution equipment.
However, recurring issues can still affect guest comfort and generate service calls.
Many hotels choose to inspect representative samples of guest room electrical systems rather than every panel.
Pool and Recreational Facilities
Pool equipment, spa systems, recreational facilities, and exterior amenities often operate in harsh environmental conditions.
Electrical equipment serving these areas should be periodically evaluated for signs of deterioration and overheating.
Exterior Electrical Equipment
Outdoor electrical equipment throughout Hawaii is exposed to some of the harshest environmental conditions found in commercial facilities.
These systems frequently experience:
- Salt air exposure
- Moisture intrusion
- UV degradation
- Corrosion
As a result, exterior equipment often deserves closer attention than similar equipment located indoors.
Hawaii-Specific Inspection Considerations
Hawaii hotels face challenges that many mainland facilities do not.
Salt Air Corrosion
Oceanfront properties are constantly exposed to airborne salt.
Over time, salt contamination can increase electrical resistance, accelerate corrosion, and contribute to overheating conditions.
Infrared inspections are particularly effective at identifying these developing issues before visible damage occurs.
Humidity and Moisture
High humidity can contribute to equipment deterioration and corrosion over time.
Electrical equipment located in mechanical spaces, parking structures, and outdoor enclosures may be particularly vulnerable.
Aging Resort Infrastructure
Many Hawaii hotels have undergone multiple renovations and electrical upgrades throughout their history.
While upgrades improve operations, they can also create a mixture of old and new equipment that may require closer monitoring.
An infrared inspection can provide valuable insight into the condition of both legacy and recently installed systems.
Building a Risk-Based Inspection Program
The most effective infrared inspection programs focus first on equipment that would create the greatest operational impact if it failed.
For most hotels, that means prioritizing:
- Main switchboards
- Emergency power systems
- Automatic transfer switches
- Transformers
- Motor control centers
- HVAC electrical equipment
- Distribution panels
By focusing on these critical assets first, Directors of Engineering can make better maintenance decisions and reduce the likelihood of unexpected electrical failures.
