FAQ
What is a building management system and what does it do in a building?
A building management system supervises technical services such as heating, ventilation or air conditioning. It centralizes measurements, operating states, setpoints and alarms to help teams control equipment, maintain the required conditions and monitor energy use.

What is the difference between GTC, GTB and BACS?
A GTC generally controls one specific technical service, while a GTB brings together several building services such as heating, ventilation, lighting and electricity. BACS is the broader term for building automation and control systems used in European and French regulations.

What building data can be used through a building management system?
Depending on the connected equipment, a building management system can use temperature, humidity, air-quality, energy-use, setpoint, schedule, operating-state and alarm data. Combining these data with weather, occupancy and historical information helps reveal how the building actually behaves.

How can climate drift be detected in a building?
Climate drift is detected by comparing measurements with setpoints and expected operation over a meaningful period. Cross-analysing zones, schedules, weather and equipment commands helps distinguish a one-off event from a persistent anomaly and investigate its cause.

Why can a building waste energy without causing visible discomfort?
Some faults remain hidden because another system compensates for them: simultaneous heating and cooling, unsuitable schedules, sensor drift, leaking valves or overridden setpoints. Occupants may remain comfortable while systems waste energy; data analysis can reveal these masked faults.

How can a building reduce energy use without compromising comfort?
First understand actual building use, then correct schedules, inconsistent setpoints, simultaneous operation and equipment drift. Changes should be measured over time to verify both the savings achieved and the maintenance of comfort, rather than applying a uniform reduction.

How can building management system alarms become genuinely useful to operations teams?
A useful alarm should be contextualized and prioritized according to its duration, recurrence, affected area and potential impact on comfort, energy or equipment. Grouping related signals and indicating a probable cause prevents alert overload and helps teams take action.

How can artificial intelligence improve an existing building management system?
Artificial intelligence can analyse building management system histories, identify unusual behaviour, correlate multiple signals and help diagnose the probable causes of drift. It complements the system by making its data easier to interpret, while safety rules and control decisions remain governed by the teams responsible for the building.
