Integrated Controls for Buildings HVAC Equipment and Utility Systems

DNC provides electrical and automation solutions for property developers, building owners, property management teams, HVAC contractors and equipment suppliers.

From building management systems and BTU metering to HVAC equipment controls and centralised utilities monitoring, we help customers connect equipment, manage operations and turn operating data into useful information.

Our scope covers electrical design consultation, control panel supply, PLC and HMI programming, SCADA and IoT integration, site wiring, testing and commissioning. We support projects for customers in Malaysia, Singapore and Europe.

Building Management and Utilities Monitoring

DNC helps property owners, developers and facility management teams gain a clear view of building services and utility consumption. We support new developments, existing building upgrades and the integration of monitoring systems across multiple properties.

Our solutions bring equipment status, meter readings, alarms and operating trends together, helping facility teams respond to faults, review consumption and identify opportunities to improve building performance.

Building Management Systems

We support BMS integration for centralised monitoring and control of connected building services. The project scope can include:

• HVAC equipment status, operating schedules and temperature monitoring.
• Chilled water pumps, cooling towers and ventilation equipment.
• Water tank levels, pump status and utility equipment alarms.
• Electrical meter readings and power consumption monitoring.
• Centralised alarm displays, historical trends and operating reports.
• Integration of existing equipment and controllers through compatible communication interfaces.

Control sequences and system interfaces are developed around the consultant’s specifications and the building’s operational requirements.

BTU Metering and Cooling Energy Monitoring

DNC supports BTU metering integration to monitor chilled water thermal energy consumption across buildings, tenant areas and cooling systems.

Solutions can include automatic collection of cooling energy, flow and temperature readings, with centralised dashboards and historical reports. These records help property teams compare consumption between areas, investigate unusual usage and support cost allocation or tenant billing based on the agreed metering and billing methodology.

Utilities Monitoring Systems

We integrate electricity, water and other specified utility meters into a common monitoring platform.

Facility teams can review consumption by building, floor, tenant or equipment group, compare usage over time and receive alerts when readings exceed defined limits. Reporting can support operating budgets, maintenance planning and sustainability reporting.

Applications include commercial offices, retail developments, mixed-use properties, industrial buildings and other managed facilities.

HVAC Control Systems for Contractors and Equipment Suppliers

DNC works with HVAC contractors, system designers and equipment manufacturers to deliver the electrical and automation scope of their equipment packages and projects.

We translate approved operating sequences into practical control systems, from individual equipment panels to coordinated HVAC plant controls.

HVAC Applications
Our control system scope can support:

• Air handling units and ventilation systems.
• Chiller packages and chilled water pumping systems.
• Cooling towers and condenser water pumps.
• Packaged air-conditioning and condensing units.
• Supply and exhaust fans.
• Temperature, humidity and pressure control.
• Equipment interfaces to BMS, SCADA and remote monitoring platforms.

Each system is configured to the equipment manufacturer’s requirements and the project’s approved control philosophy.

Equipment Sequencing and Operational Control

We develop PLC and HMI applications for equipment start-up and shutdown, operating modes, duty and standby changeover, variable-speed control, alarms and interlocks.

Operator interfaces provide clear equipment status, adjustable operating parameters, fault information and historical trends. Where required, individual equipment packages can be integrated into a central supervisory system.

Electrical Engineering and Control Panels

DNC provides electrical design consultation and panel supply to support both building utilities and HVAC equipment projects.

Our scope includes local control panels, motor control centres, PLC panels and variable-speed drive panels, together with electrical schematics, I/O schedules and interface coordination.

Panel configurations can include segregation up to Form 4b and enclosure protection up to IP66. Project-specific NEMA enclosure requirements, CE conformity and UL compliance requirements can be supported through the applicable design, component selection, documentation and verification arrangements.

SCADA IoT and Remote Monitoring

We connect HVAC equipment, building systems and utility meters to SCADA and IoT platforms for centralised visibility.
Solutions can include live dashboards, alarm notifications, historical data logging, trend analysis and automated reports.

Authorised users can monitor equipment performance and consumption across individual facilities or multiple locations.
DNC also supports PLC, HMI and industrial network cybersecurity requirements, including network segmentation, user access controls and secure remote access arrangements appropriate to the project.

Site Wiring Testing and Commissioning

Our project support extends from panel delivery to site integration and handover.

Services include field wiring and termination, instrument and communication checks, I/O verification, functional testing and commissioning of approved operating sequences.

We coordinate with consultants, mechanical contractors, equipment suppliers and facility teams to verify system interfaces and provide the agreed drawings, software backups and operating documentation.
