Combined Access: How to Integrate Smart Locks with Other Building Systems

What is combined access?

In an increasingly connected world, buildings—whether residential, office, or tourist—are evolving towards smart models where all their components are interconnected. Smart locks are one of the key elements in this transformation. But their true potential unfolds when integrated with other building systems, creating safer, more efficient, and more comfortable environments. In this article, we explore how these combined access systems work, what advantages they offer, and how to carry out effective integration.

Combined access refers to the interconnection of access control systems (such as smart locks) with other building technologies. This can include automation, security, energy, HVAC, visitor management systems, among others.

The goal is not only to control who enters and exits but to orchestrate a complete and efficient experience for users, residents, guests, or workers. In essence, access ceases to be an isolated function and becomes a key piece within the building's management ecosystem.

What systems can be integrated with a smart lock?

Modern smart locks, like those offered by Raixer, are designed to communicate with a wide variety of systems. Some of the most common include:

1. Lighting and HVAC automation

When a person accesses a space using a smart lock, the system can turn on the lights, adjust the temperature, or activate a pre-configured mode based on the time or user profile.

For example: upon entering a shared office, the system can turn on only the area assigned to the user and activate the air conditioning if the temperature exceeds 25°C.

2. Energy management systems

Knowing who is in the building and when allows for optimising energy consumption. If no one is present, everything can be turned off. This integration is especially useful in buildings with energy efficiency certifications such as BREEAM or LEED.

3. Smart lifts

By using a code or card to access the building, the system can automatically call the lift and direct it to the corresponding floor, without the need to press buttons. This functionality improves accessibility and user experience.

4. Video surveillance and alarms

When a lock is activated, a camera or alarm system can also be activated (or deactivated). This integration is key for security, as it allows suspicious accesses to be recorded or alerts to be sent to responsible parties in real time.

5. Attendance and clock-in control

In companies, smart locks can be integrated with time and attendance systems, allowing building entry to automatically record the worker's start time.

6. Space reservation management

In coworking spaces or corporate buildings, access can be linked to a booking system: if you have reserved a meeting room from 10:00 to 11:00, you will only be able to open the door associated with that room during that time.

7. Virtual assistants and home automation

Assistants like Alexa or Google Home can be integrated with access systems to allow voice-activated unlocking, or to activate complete scenes like “night mode,” which closes doors, lowers blinds, and turns off lights.

Key benefits of combined access

Implementing combined access is not just a matter of technology; it also brings clear and measurable advantages in different areas:

1. Enhanced security

Automation reduces human error: programmed access, automatic off-hours blocking, notifications for unauthorized use, etc.

2. Operational efficiency

Building or property managers can automate processes, reduce operational workload, and make data-driven decisions (for example, knowing which spaces are used most).

3. Improved user experience

From contactless entry to a personalised space, combined access offers a fluid, faster, and more tailored experience for the end-user.

4. Cost savings

By optimising energy consumption, reducing unnecessary travel (e.g., to deliver physical keys), and preventing incidents, tangible savings are generated.

Real-world use cases

Office buildings

A shared workspace with code access that updates weekly for users. Upon entry, the system activates lighting and HVAC only in reserved areas. Reservations are made from an app that automatically generates access.

Tourist properties

The guest receives a code that only works during their reservation. Upon entry, the air conditioning is activated and the alarm is deactivated. The system also notifies housekeeping after the guest's departure. All without human intervention.

Residential communities

Residents access the building entrance and storage area with the same card or app. The system can grant temporary access to delivery personnel or technicians and record entries for greater security.

How to achieve successful integration?

Integrating a smart lock with other systems requires planning, compatible technology, and a mid-term vision. Here are some key steps:

1. Needs assessment

Before installation, it is important to define what is to be achieved with the integration. Energy savings? Improved attendance control? Optimised security?

2. Technological compatibility

Not all systems “speak the same language.” It is essential to choose locks with open APIs or that are compatible with standard protocols such as MQTT, Z-Wave, Zigbee, Wi-Fi, or Bluetooth.

3. Centralisation on one platform

The more systems there are, the more important it is to have a centralized control panel. Many providers offer dashboards that integrate all data in real time.

4. Information security

System integration involves sharing data. It is essential that the provider complies with GDPR and uses robust encryption and authentication to protect access.

5. Support and scalability

Opt for solutions that can grow with the building or business. From adding more locks to integrating with new technologies in the future.

Raixer: smart access with total integration

Raixer is one of the most advanced access control solutions in the Spanish market, designed to easily integrate with other building systems. Its technology allows managing access by PIN code, NFC, mobile app, remote control, voice assistants, and cards, giving it unique flexibility.

Furthermore, Raixer offers a powerful API that facilitates integration with booking platforms, automation systems, energy management, or attendance control. Whether for a tourist apartment, a hybrid office, or an entire building, Raixer allows digitizing and centralizing all access, offering security, comfort, and scalability. Its modular approach allows you to start with one door and scale to a complete solution without technical complications.

The future of buildings is connected

Combined access is not a fad, but a structural trend that defines how 21st-century spaces should be: secure, sustainable, smart, and user-centric.

Smart locks cease to be a simple device and become the heart of an interconnected system. And with tools like Raixer, any building—new or old—can make the leap to this new era without construction work or complexities.

Investing in integration not only improves the current experience but also prepares the building for the future: more adaptable, more profitable, and more human.
