How to Integrate Access Control Systems into Modern Building Design

Modern buildings are becoming smarter, but designing them is also becoming more complicated. Architects must consider security, accessibility, energy efficiency, and the changing needs of occupants, often within the same floor plan.

The numbers highlight this shift. According to 2024 research from Lawrence Berkeley National Laboratory, 95% of U.S. commercial buildings are smaller than 50,000 square feet, yet only 13% of these smaller buildings have building automation systems. Meanwhile, the U.S. Department of Energy reports that advanced building controls can reduce commercial HVAC energy use by approximately 30%. Although these figures concern building automation rather than access control specifically, they show the opportunity for more integrated building technology.

Security deserves the same attention. In a modern office, hospital, or apartment building, access control should not be something added after construction. Door placement, electrical infrastructure, network connections, and emergency exits all influence how effectively a security system works.

By planning access control components during the design stage, architects can create buildings that are secure, convenient, and easier to manage.

This article explains how to integrate readers, controllers, electronic locks, and management software into building layouts while balancing security, accessibility, aesthetics, and future expansion.

1. Start Access Control Planning During the Architectural Design Phase

One of the biggest mistakes in building security is treating access control as a final installation task. When architects wait until construction is nearly complete, adding electronic locks, readers, and wiring may require changes to finished walls, doors, and electrical systems.

Instead, access control planning should begin alongside architectural layouts and circulation planning.

For example, consider a five-story office building with 200 employees. Its main entrance, employee-only floors, server rooms, and storage areas all require different security levels. Designing these requirements early helps architects determine where controlled doors belong and how people should move between public and restricted areas.

A practical approach includes:

• Identifying security zones: Separate public entrances, employee areas, visitor spaces, and restricted rooms.

• Planning movement: Ensure authorized users can move conveniently without unnecessary checkpoints.

• Coordinating infrastructure: Reserve appropriate space for wiring, controllers, and power supplies.

• Considering future changes: Allow for additional doors, tenants, and changing access requirements.

Early coordination also reduces conflicts between security equipment, interior finishes, and accessibility requirements.

The goal is to make security part of the building's functionality rather than an obstacle to its everyday use.

2. Choose Access Control Components That Fit the Building Layout

Every electronic access control system relies on several interconnected devices. Understanding their roles helps architects make better decisions about equipment placement, infrastructure, and door specifications.

The five essential components are:

Component	Primary function	Architectural consideration
Credentials	Identify authorized users	Choose cards, fobs, PINs, or mobile access
Access readers	Capture credentials	Position at convenient, accessible heights
Controllers	Verify permissions and operate doors	Provide secure mounting and cable routes
Electronic locks and sensors	Secure doors and detect their status	Coordinate with door hardware and life-safety requirements
Management software	Manage permissions and activity records	Plan network connectivity and administration

These elements must function together. A reader may successfully scan a card, but the door will not unlock unless the controller verifies permission and signals the appropriate locking hardware.

For a practical example, Coram's approach to access control components combines cloud-managed software with dedicated controllers and compatible door hardware. Its DC-41 controller supports up to four doors, while the DC-11 supports one. The platform also accommodates existing Wiegand and OSDP readers, along with cards, fobs, PINs, and mobile app unlocking. Where compatible cameras are installed, door events can be paired with video. This illustrates how a building can accommodate both centralized management and different door configurations without requiring identical hardware at every entrance.

Architects should therefore evaluate access control as an interconnected system, not simply a collection of locks and readers.

3. Integrate Readers and Electronic Locks Without Compromising Aesthetics

Modern architecture often emphasizes clean entrances, glass partitions, open interiors, and minimal visible hardware. Security devices must fit these design priorities without becoming difficult to use.

Readers should be positioned where occupants naturally approach doors. They should also be accessible to people with disabilities and protected from weather or accidental damage when installed outdoors.

Electronic locking hardware requires equally careful planning. The appropriate solution depends on the door material, opening direction, traffic volume, and emergency egress requirements.

Common options include:

• Electric strikes: Often suitable for compatible conventional door assemblies.

• Electromagnetic locks: Used in selected applications requiring specific release and life-safety arrangements.

• Electrified handles: Combine electronic access with familiar mechanical operation.

• Electrified exit devices: Support controlled entry while preserving required exit functions.

Consider a modern corporate lobby with glass doors. A poorly coordinated security installation might require visible conduits or awkwardly positioned readers that interfere with the entrance's appearance.

Planning equipment locations before construction allows designers to coordinate cabling, mounting details, and compatible hardware with the architectural finishes.

However, aesthetics must never override emergency egress. Lock selection and release arrangements must comply with applicable building, fire, and accessibility codes.

4. Design Controller Locations, Wiring, and Power Infrastructure

Readers and locks are the visible parts of access control, but much of the system operates behind walls and inside electrical or communications spaces.

Controllers receive credential information, evaluate access permissions, and send signals to locking hardware. They also connect to door-position sensors, request-to-exit devices, networks, and power supplies.

Their location can significantly affect installation complexity.

For example, a building with 40 controlled doors may benefit from distributing controllers across secure communications or electrical rooms rather than routing every cable to one distant location.

Architects and engineers should coordinate several details during design:

• Provide secure, accessible spaces for controller enclosures.

• Plan cable pathways between readers, controllers, locks, and sensors.

• Account for network connections and appropriate power supplies.

• Determine which equipment requires battery backup.

• Coordinate emergency release arrangements with the fire protection design.

Power failure deserves particular attention. Some locks release when power is lost, while others remain locked but must still permit code-compliant exit.

These decisions cannot be left entirely to software configuration. They depend on physical hardware, wiring, and the building's life-safety requirements.

A well-designed infrastructure makes the system easier to maintain, troubleshoot, and expand.

5. Connect Access Control With Other Smart Building Technologies

Access control becomes more useful when it works alongside other building systems.

For example, an office building may combine access permissions with visitor management, security cameras, intrusion alarms, and selected building automation functions.

The U.S. Department of Energy estimates that high-performance building controls can deliver average annual HVAC energy savings of around 30% across applicable commercial building types. This is not an access control savings estimate, but it demonstrates why coordinated building systems are increasingly important.

Access data can also support operational decisions when appropriate integrations are available.

Consider a workplace where employees use credentials to enter restricted areas. The access control platform can record successful and unsuccessful entry attempts, while connected video surveillance may provide additional context for investigating unusual events.

Useful integration opportunities include:

• Video surveillance: Associate access events with relevant camera footage.

• Visitor management: Issue temporary permissions to approved visitors.

• Intrusion detection: Coordinate security alerts with access activity.

• Building automation: Support authorized occupancy-related workflows where compatible systems permit them.

  
  

Architects should discuss these requirements with security and IT teams before finalizing technology specifications.

Interoperability, cybersecurity, data privacy, and long-term maintenance matter just as much as the initial installation.

6. Balance Building Security With Accessibility and Emergency Safety

A secure building must also be safe and convenient for everyone who uses it.

Poorly designed access control can create unnecessary barriers for wheelchair users, visitors, older adults, and employees carrying equipment. It can also interfere with emergency evacuation if locking arrangements are not coordinated correctly.

Architects should therefore evaluate security from the occupant's perspective.

For example, a hospital entrance may need to accommodate patients using mobility aids, staff moving equipment, and visitors unfamiliar with the building. An access reader positioned awkwardly or a door that closes too quickly can create practical accessibility problems.

Important considerations include accessible reader placement, adequate door maneuvering clearance, appropriate door-opening force, emergency exit operation, and clear wayfinding.

Security and life-safety specialists should also verify how doors behave during fire alarms, power failures, and other emergencies.

The objective is straightforward: prevent unauthorized entry without making authorized access unnecessarily difficult or compromising safe evacuation.

7. Plan for Future Expansion and Long-Term Building Management

Buildings rarely operate exactly as originally planned throughout their lifespan.

An office may add new departments, a commercial property may welcome different tenants, or a healthcare facility may convert existing rooms into restricted treatment areas.

Access control should accommodate those changes without requiring extensive reconstruction.

For instance, a building initially designed for 100 employees might eventually accommodate 250. If its system supports additional credentials, controllers, and controlled doors, administrators can expand security coverage as occupancy changes.

Cloud-managed platforms can also simplify certain administrative tasks, including updating permissions, reviewing access records, and managing multiple locations.

Before finalizing the design, architects and property owners should consider:

• Whether additional controlled doors can be supported

• How easily access permissions can be updated

• Whether existing readers and wiring can be retained during upgrades

• What happens when internet connectivity is interrupted

• How ongoing maintenance and software costs affect ownership

Planning for adaptability helps protect the building owner's investment and reduces the likelihood of expensive modifications later.
