Building Management System (BMS)

Smart Building Automation: Run the Whole Building from One Screen

A building management system (BMS) monitors and automates a building's heating and cooling, lighting, energy, fire alarm and access systems from a single panel. We install BMS in factory office blocks, shopping centres, hotels, office buildings and campuses, connecting mixed-brand equipment over Modbus, BACnet, KNX and DALI without ripping out what already works.

In most buildings, heating and cooling, lighting, fire and access systems come from different suppliers, each with its own control panel. The result is familiar: empty floors heated over the weekend, lights left on overnight, faults noticed only when someone complains, and an energy bill nobody can explain.

During the site survey we inventory the equipment already in place, connect different brands over open protocols and give your facilities team a single panel to monitor and control the building. We can build a system from scratch for a new building or integrate with the HVAC and lighting you already have.

A typical scenario: in a factory's office block, when the last person badges out on Friday evening, that floor's heating, cooling and lighting switch off automatically; on Monday morning the first card read brings the floor back on. If a fan coil fails overnight, the facilities team finds out from an alarm on the web or mobile panel rather than from complaints in the morning. By month-end, which floor and which system used how much is clear before the bill arrives.

Building management system (BMS): HVAC, lighting and energy managed from one panel

Which Building Systems Can a BMS Control?

HVAC Automation

Air-handling units, fan coils, chillers and boilers come under central control. Schedules, room-level setpoints and occupancy data make sure plant runs only when, and only as hard as, it needs to.

Lighting Control

DALI or 0–10V luminaires are managed centrally: automatic switch-off in empty areas, daylight dimming near windows and scenes for meetings, cleaning or night-time.

Energy Tracking

Consumption is tracked live by panel and floor. You are warned before you approach your contracted capacity or breach reactive-power limits, and you can see which system is using what before the bill arrives.

Access Control Integration

Works alongside card and fingerprint access systems. The first entry into a zone switches on its HVAC and lighting; after the last person leaves, they switch off, so out-of-hours consumption drops without anyone having to remember.

Fire Alarm Integration

Linked to the fire alarm panel. When an alarm is raised, a predefined scenario runs: HVAC switches to smoke-control mode, lifts are called to the ground floor and emergency lighting comes on.

Central Monitoring Panel

The status of every building system on one screen: consumption, floor and room temperatures, door states and active alarms. Your facilities team works from web or mobile, with permissions set per user.

Where Do BMS Energy Savings Come From?

Time
Scheduled operation

Heating, cooling and lighting run only during the hours the space is used

Occupancy
Empty-space detection

Sensor and access data identify unoccupied areas so they can be shut down

Demand
Peak-load control

Non-critical loads are shed in sequence before contracted capacity is exceeded

Evidence
Verified results

Each change is measured against meter data, before and after

No Need to Rip Out What Works

Working equipment stays in place. We connect your existing HVAC, lighting and security systems through suitable gateways and controllers, with support for Modbus, BACnet, KNX and DALI. For access control we also offer SmartPass, our own product from the Smart360 family: door access, time and attendance, visitor reception and canteen management run on the same card and the same panel. To buy SmartPass, simply fill in the SmartPass sales form. If you need consumption down to line and machine level, see our energy monitoring service.

Questions Asked Before Deciding

  • "Will we be tied to one brand?" Because we work over open protocols such as Modbus, BACnet, KNX and DALI, you remain free to choose equipment from different manufacturers.
  • "How much will we save?" We do not promise a percentage before the survey; savings depend on how the building is used. Instead, we show the effect of every change against meter data, before and after.
  • "Who do we deal with after installation?" Survey, installation, commissioning and training come from one team, followed by 24/7 technical support. We have built software and hardware in the same team since 2013.
  • "How is the cost set?" Your building's equipment is inventoried during the survey, then we prepare a written proposal setting out scope, phases and cost. Technical feasibility is free for projects involving hardware.

For more depth, read our guides: the smart building and BMS guide, BACnet in building automation and building and energy management in hospitals. All articles are listed under Industry 4.0 guides.

Have your floor plans and a list of existing systems to hand, and we will work out together during the survey how each piece of equipment will be connected. If you also want to monitor machines on the production floor, our SCADA and HMI service comes from the same team.

Questions we hear most often

Frequently Asked Questions

What is a building management system (BMS)?

A building management system (BMS), also called smart building automation, monitors and automates a building's heating and cooling, lighting, energy, fire alarm and access systems from a single panel. Systems that came from different suppliers, each with its own control panel, are brought onto one screen, and the facilities team manages the whole building from web or mobile with per-user permissions.

Can a BMS be installed in an existing building?

Yes. You do not need a new building, and working equipment stays in place. During the site survey we inventory your existing HVAC, lighting and security equipment and connect different brands through suitable gateways and controllers. New-build installations are also possible. We install BMS in factory office blocks, shopping centres, hotels, office buildings and campuses.

Which protocols does your BMS support?

Modbus, BACnet, KNX and DALI. Lighting can be managed over DALI or 0–10V. These open protocols let air-handling units, fan coils, chillers, boilers and lighting from different manufacturers run under one building management system, so you are not tied to a single vendor.

How does a BMS save energy?

Savings come from four places: heating, cooling and lighting run only during occupied hours; sensor and access data identify empty areas so they can be shut down; non-critical loads are shed before contracted capacity is exceeded; and every change is measured against meter data, before and after. Savings are therefore demonstrated by measurement rather than assumed.

Does a BMS work with access control and fire alarms?

Yes. It works with card and fingerprint access systems: the first entry into a zone switches on its HVAC and lighting, and they switch off after the last person leaves. When the fire alarm is raised, a predefined scenario runs: HVAC switches to smoke-control mode, lifts return to the ground floor and emergency lighting comes on. Our own SmartPass can handle access control.

What is the difference between a BMS and SCADA?

A BMS (building management system) is designed to run a building's HVAC, lighting, energy, fire and access control systems, with a focus on comfort and energy efficiency. SCADA monitors process data from PLCs in production plants, manages alarms and allows operators to intervene on machines. In factories the two often work together: the office building runs on a BMS and the production floor on SCADA.

Which buildings benefit most from building automation?

Building automation suits offices and business towers, factory office buildings, shopping centres, hotels, hospitals, schools and campuses: buildings with heavy heating, cooling and lighting loads where different areas are used at different times. The benefit of a single panel is greatest where systems come from several suppliers and are each run from their own separate panel.
