Controls & Building Systems
Building Automation, Access Control and Integrated Building Systems
Modern facilities depend on connected controls to manage comfort, schedules, access, alarms, and the movement of people through the building. When these systems operate in silos, facilities teams lose visibility.
What Is a Building Automation System?
A building automation system, or BAS, is the centralized control platform that manages a facility's mechanical and electrical equipment. It handles equipment scheduling, temperature and humidity setpoints, sensor inputs, alarms, and performance trending, and gives facilities staff one place to see how building systems are operating. A building management system, or BMS, describes the same category of platform.
Integrated Controls Capabilities
Building automation and management systems - Support for BAS and BMS environments
HVAC controls coordination - Troubleshooting when concerns involve both physical HVAC equipment and the control sequence.
Building access control - Support for card readers, credentials, controllers, request-to-exit components, schedules, and permissions.
Automatic gates and controlled openings - Coordination between access-control logic and the mechanical or safety components that manage the opening.
Low-voltage and network infrastructure - Support for cabling, pathways, panels, power supplies, communication devices, and network dependencies.
Sensors, alerts, and connected devices - Coordination of monitoring points and notifications.
System integration and vendor coordination - Controls manufacturers, software providers, security partners, technicians, IT resources, and stakeholders into one coordinated service path.
From Disconnected Platforms
to Coordinated Response
A facility may contain multiple generations of equipment and several proprietary platforms. We help you clarify what each system controls, how information moves, who owns the response, and where modernization would create value.
- Operational mapping: Systems, interfaces, critical points, dependencies, vendors, and escalation responsibilities documented in one place.
- Alarm and exception management: Attention focused on conditions that require investigation, rather than treating every signal as equally urgent.
- Trend-based troubleshooting: Available histories, schedules, point values, and equipment behavior used to support diagnostics and identify recurring conditions.
- Access governance support: Credential workflows, schedules, permissions, changes, and service responsibilities organized around your operating requirements.
- Lifecycle planning: Obsolete components, unsupported platforms, integration gaps, and modernization priorities identified for future planning.
Technology Connected to Facilities Operations
We link system alerts and access issues to centralized work orders, technical dispatch, asset records, service history, and account-level reporting. Cybersecurity policy, enterprise IT governance, and platform ownership remain client responsibilities, defined with your technology stakeholders as part of each scope.
Frequently Asked Questions
What is the difference between building automation and access control?
Building automation manages equipment and environmental conditions, such as HVAC scheduling, setpoints, and alarms. Access control manages who can enter which door, when, using credentials, readers, and electronic locking hardware.
Can TDG work with our existing controls platform?
Yes. Most facilities run several manufacturers and multiple generations of equipment side by side. We work with the platforms in place and coordinate with the original manufacturer or software provider when a scope requires it.
Who handles the physical door when access control fails?
Our Integrated Controls team addresses credentials, readers, controllers, and access logic, while our Commercial Door team addresses the door, frame, operator, and mechanical hardware. Both sit under one account.
