The hospitality industry is experiencing significant growth, with an estimated 2,707 new hotels expected to be built worldwide in the coming year. Operating 24/7 and 365 days a year, hotels are among the largest consumers of energy and water per square meter. It is estimated that the average hotel room incurs annual energy costs of approximately $2,200, with 45% allocated to heating and air conditioning (HVAC) and 25% to lighting. Guests can be encouraged to make their stay more sustainable, and many major names in the industry have already begun promoting this concept. However, without the appropriate technology, sustainability initiatives may not reach their full potential.

What can we do for hotels with building automation and the Guest Room Management System (GRMS)?

Intelligent Control of Lighting and HVAC

Implement sensors and presence logic in rooms to automatically adjust lighting and temperature based on occupancy and environmental conditions. This optimizes energy use, reducing operational costs. Utilize preset lighting scenarios for different activities (rest, reading, work) and adjust HVAC to ensure maximum guest comfort. Integrate these systems with booking systems to activate heating or cooling shortly before guests’ arrival, ensuring a welcoming room upon arrival and automatically turning off HVAC when the room is vacant to save energy.

Centralized Supervision and Proactive Management

With the KNX system, hotels can easily monitor and manage every room from the reception desk, including real-time control of lighting, temperature, and ventilation. The system detects anomalies and faults, sending immediate notifications to the reception for quick intervention, enhancing guest safety and satisfaction. By monitoring the state of utilities, the reception can quickly coordinate maintenance interventions, reducing disruptions and downtime. Collected data allows for preventive maintenance planning, reducing the risk of failures. Centralized supervision optimizes operations, improving efficiency and creating a comfortable and sustainable environment for guests.

Solutions for Small Structures and Airbnb

Even small establishments like Airbnb or Bed & Breakfast can greatly benefit from implementing a smart hotel system. One of the main features is the virtual reception, allowing guests to access rooms via a QR code or a remotely modifiable PIN code, eliminating the need for a physical reception. The code is active only during access hours and can be changed remotely.

In terms of safety and comfort, smoke, water, noise, and temperature sensors ensure a safe and comfortable environment for guests. Faults can often be identified before impacting guests, thus improving the quality of service offered.

Regarding energy efficiency, air conditioning automatically turns off in case of open windows or absence of people, reducing energy costs by up to 40%. This not only helps contain expenses but also contributes to a more sustainable environment.


In summary, adopting sustainable technologies and practices not only helps reduce operating costs but also enhances the guest experience, making hotels more attractive to environmentally conscious customers.
