LUMEN / BUILDING MANAGEMENT

Building management systems designed around facility operations.

We design and implement BMS solutions covering HVAC controls, DDC controllers, BACnet and Modbus integration, energy monitoring and operational alarms.

Building management systems

From field devices to the central operating platform.

Each scope is defined by the equipment, control points, communication protocol and required operating outcomes.

Commercial AHU, chilled-water pumps and mechanical plant controlled by a building management system
01

HVAC and mechanical-system controls

Monitor and control AHUs, FAHUs, FCUs, VAV boxes, pumps and chillers against operating schedules, setpoints and occupancy.

  • Temperature, valve and damper control
  • Pump and fan staging with VFD monitoring
  • Chillers and chilled-water circuit status
DDC building-automation control panel with I/O modules, field wiring and controller terminals
02

DDC controllers and field devices

Specify direct digital controllers, DI/DO/AI/AO points, sensors and actuators around the approved requirements of each plant item.

  • Documented controller and I/O schedules
  • Temperature, humidity and pressure sensing
  • Panel, field-device and point identification
BACnet IP and Modbus RTU protocol gateway connecting commercial equipment to a BMS
03

BACnet and Modbus integration

Integrate BACnet/IP, BACnet MS/TP, Modbus TCP and Modbus RTU equipment through documented addressing, gateways and point mapping.

  • Integration matrix and approved points list
  • Network topology, device IDs and gateways
  • Read/write permissions, units and limits

04

Supervisory platform and HMI graphics

Provide supervisory graphics for floor plans, plant schematics, equipment status and live readings with defined operator permissions.

  • Supervisor, workstation and HMI graphics
  • Building, system and equipment dashboards
  • Operator access levels and system backups
BMS alarm and event workstation showing prioritized faults, timestamps and alarm acknowledgments
05

Alarms and event logs

Organize equipment faults, threshold deviations and communication failures around approved alarm priorities, delays and acknowledgments.

  • Alarm classification and acknowledgment
  • Operational event history and fault logs
  • Deadbands, delay settings and escalation

06

Energy monitoring and metering

Collect main and sub-meter data to review consumption and demand by building, area or system, without assuming unverified savings.

  • Electrical meters and submeters
  • Consumption trends and demand profiles
  • Scheduled reports based on available points
BMS operator interface for AHU schedules, chiller staging and duty-standby pump operating sequences
07

Schedules and sequence of operation

Configure sequences of operation, schedules, occupancy, operating modes and interlocks in line with the approved engineering intent.

  • Daily, weekly and holiday scheduling
  • Setpoints, occupancy and manual override
  • Duty/standby logic and failure responses

08

Third-party and supporting systems integration

Connect approved electrical, UPS, generator, metering and KNX interfaces; fire-system monitoring never replaces life-safety functions.

  • Electrical, generator and UPS status where specified
  • KNX and third-party system gateways
  • Fire interfaces aligned with approved cause and effect
System architecture

BMS layers and data flow, clearly defined.

The architecture progresses from field measurement to control, integration and supervision while preserving independent life-safety systems.

01

Field sensors and devices

Measure temperature, humidity, pressure, flow and defined equipment states.

02

DDC control layer

Process physical points, control logic, interlocks and approved operating sequences.

03

Integration network

Connect controllers and packaged equipment through BACnet, Modbus or approved interfaces.

04

Supervisory HMI platform

Display site graphics, live values, commands and operator access permissions.

05

Alarms, trends and reporting

Maintain fault records, event history, trend data and energy-monitoring reports.

Engineering and handover

BMS deliverables required by consultants and operators.

The delivery scope is documented from point lists and control philosophy through testing, backups, training and warranty.

01

Survey and scope definition

Review drawings, inventory equipment and establish the operational BMS boundary.

02

Points list and control philosophy

Prepare points lists, I/O schedules and documented sequences of operation.

03

Network and integration design

Document topology, addressing, gateways and the integration matrix.

04

Panels and engineering drawings

Define DDC panels, controllers, field devices and connection details.

05

Programming and operator graphics

Configure operating logic, HMI screens, schedules and alarm handling.

06

Testing and commissioning

Perform point-to-point checks, FAT, SAT and commissioning as contractually specified.

07

Handover and training

Provide as-built records, program backups, user configuration and operator training.

08

Warranty and support

Document warranty coverage and the agreed post-handover support scope.

Facilities and sectors

A BMS designed around each facility's operating requirements.

The integration scope follows the facility type, installed equipment, project drawings and approved operational requirements.

01

Government facilities

Centralized visibility of mechanical systems, equipment states and energy points.

02

Corporate offices

Structured HVAC schedules, occupancy logic, alarms and operational supervision.

03

Hotels and hospitality

Monitor HVAC, service areas and approved interfaces with available guest-room systems.

04

Healthcare and education

Supervise designated systems according to each facility's engineering approvals.

05

Retail and mixed-use sites

Coordinate shared equipment, multiple operating areas and energy-meter visibility.

KNX integration

When a building needs centralized supervision and local control.

KNX areas can interface with the BMS through approved gateways and point schedules while preserving local lighting, shading and HVAC functions.
