Frequently asked

Glossary

1

BMS (Building Management System)

A central software and hardware system that monitors and controls building services such as HVAC, lighting, energy use and security. At a smart-building event, BMS platforms are usually evaluated for open protocols, dashboards and integration with tenant or facility workflows.

2

BAS (Building Automation System)

The control layer that automates equipment such as air handling units, chillers, boilers and lighting schedules. BAS and BMS are often used interchangeably, though BAS usually refers more narrowly to the controls that execute sequences.

3

BEMS (Building Energy Management System)

A system focused on measuring, monitoring and reducing energy consumption across a building or portfolio. BEMS tools typically combine metering data, tariff signals and equipment schedules to identify savings and verify performance.

4

IoT (Internet of Things)

Networked sensors and devices that collect and exchange data. In buildings, IoT covers environmental sensors, smart meters, occupancy detection, leak sensors and connected equipment used for analytics and predictive maintenance.

5

Digital twin

A digital representation of a building, system or asset that is kept in sync with real-world data. Digital twins support commissioning, space planning, energy simulation and fault detection across the building lifecycle.

6

Interoperability

The ability of products from different vendors to exchange data and work together through open standards and APIs. Buyers at smart-building fairs often test interoperability claims against KNX, BACnet, Modbus and IP-based protocols.

7

KNX

A worldwide open standard for home and building control, covering lighting, blinds, HVAC, security and energy management. KNX devices are certified for interoperability, which makes the standard relevant to specification and retrofit decisions.

8

BACnet

A communication protocol widely used in building automation and control systems. BACnet supports interoperability between HVAC, lighting, access and energy-management devices from different manufacturers.

9

Demand response

A programme that adjusts building electricity use in response to grid signals or price changes. Demand-response controls may dim lighting, shift cooling setpoints or discharge batteries during peak periods.

10

Energy performance contract (EPC)

A contractual arrangement in which an energy service company guarantees energy savings and is paid from the resulting cost reductions. EPCs are common in public-sector and large commercial retrofit projects.

11

ESCO (Energy Service Company)

A company that develops, installs and often finances energy-efficiency or renewable-energy projects, typically sharing the savings with the building owner. ESCOs appear at smart-building events as project developers and technology integrators.

12

Smart metering

Interval meters and data platforms that record electricity, gas, water or heat use at higher frequency than traditional meters. Smart-meter data feeds benchmarking, anomaly detection and tenant billing.

13

HVAC

Heating, ventilation and air-conditioning equipment and controls. HVAC is usually the largest energy user in commercial buildings, so it is a central topic for building-automation and decarbonization exhibitors.

14

OT/IT convergence

The integration of operational technology, such as building controls and sensors, with information technology networks and cloud platforms. Convergence improves analytics but requires cybersecurity controls and clear responsibility between facilities and IT teams.

15

Indoor environmental quality (IEQ)

The combination of indoor air quality, thermal comfort, lighting and acoustics that affects occupant health and productivity. IEQ monitoring is increasingly linked to building certification, ESG reporting and tenant experience.
