How much does an empty room cost? Ekonex automation for B&Bs and hotels

An empty guest room should not consume as much energy as an occupied one.

Yet in many B&Bs, farm stays, residences and boutique hotels, heating, cooling, lighting and electrical loads continue to operate even when the guest is away or the room has not been booked. The cost may be invisible at reception, but it appears clearly on the energy bill.

Turning everything off is not the answer. A hospitality property must protect the building, control humidity and temperature and, above all, provide a welcoming room when the guest arrives.

Ekonex turns these requirements into one coordinated strategy. Every room is managed according to its real status, without sacrificing comfort and without asking staff to constantly check thermostats, windows and switches.

The hidden cost of empty rooms

A room can be vacant, assigned, being prepared, occupied or temporarily empty while the guest is out. Treating all these situations in the same way means consuming energy without creating value.

Ekonex can associate each status with a specific strategy:

• unbooked room: maintenance temperature, unnecessary lighting and loads switched off;

• assigned room: gradual preparation before arrival;

• guest present: full comfort and authorised controls available;

• guest away: controlled reduction in consumption without compromising their return;

• cleaning or maintenance: a dedicated staff mode with fault reporting.

The difference is not simply between on and off. It is knowing exactly when energy is useful.

Open window? Climate control stops wasting energy

A window or glazed balcony door left open while heating or cooling continues to operate is one of the most common sources of waste in hospitality buildings.

Using dedicated contacts, Ekonex detects the opening and can temporarily pause climate control in that room. When the window is closed, the system restores regulation according to the configured conditions.

The guest does not need to remember a procedure and the manager does not need to intervene: the room automatically avoids heating or cooling the outdoors.

Comfort can begin before check-in

Saving energy should never mean welcoming guests into a cold room in winter or an overheated room in summer.

As arrival approaches, the assigned room can move from maintenance mode to comfort mode. Temperature, ventilation, courtesy lighting and solar shading are prepared at the right time, based on the characteristics of the room and its systems.

At check-in, a digital credential or temporary code can grant access only to authorised areas and only for the booked period. At check-out, permissions expire and the room automatically returns to the mode selected by the manager.

The result is a smoother guest experience and fewer repetitive tasks for staff.

One QR code, four services immediately available

In a real solution delivered by Ekonex, every suite has its own dedicated Guest access. The manager generates the QR code associated with the room. Without installing an app or knowing anything about the building's technical configuration, the guest reaches only the services made available to them.

From a single mobile interface, guests can:

• connect to the dedicated guest Wi-Fi network;

• play music and control authorised audio functions;

• activate lighting scenes prepared for the room;

• adjust the temperature within limits defined by the property.

Guest freedom and management control remain completely separate. Guests can choose their preferred comfort level, but cannot alter technical parameters, exceed temperature limits, control other rooms or access the building-management dashboard.

Guest limits can vary by season, room and suite category. At check-out, access can be disabled and the room automatically returns to the operating mode selected by the property.

This small detail transforms the experience: no app to find, no unfamiliar remote control and no complicated instructions. The guest scans the QR code and the room presents only the controls they need.

The QR code shown in the public image is a non-functional demonstration and does not provide access to the real installation.

Every room on one dashboard

Reception should not discover a problem only after a guest complains.

Through a single interface, Ekonex can display room status and the information that genuinely matters to operations:

• presence and occupancy status;

• temperature and climate demand;

• doors or windows left open;

• active lighting and electrical loads;

• position of blinds, shutters or external shading;

• consumption and energy anomalies;

• cleaning or maintenance requests;

• technical alarms configured for the property.

Managers gain a complete overview, while each staff member sees only the controls and information appropriate to their role.

Solar energy, shading and climate become part of operations

Rooms exposed to sunlight do not all behave in the same way. Orientation, time, season and weather affect both comfort and the workload placed on building systems.

Ekonex can coordinate shading to limit summer overheating or capture beneficial solar gain during winter. If the property has photovoltaic panels and battery storage, available production can be considered when managing climate control, domestic hot water and other programmable loads.

An occupied room receives the comfort it requires. A vacant room remains protected and monitored, but does not consume energy as if someone were staying there.

Not a standard product, but a strategy for your property

A four-room B&B does not have the same requirements as a hotel, farm stay or serviced residence. Systems, schedules, services, staff organisation and the desired level of automation all differ.

This is why Ekonex begins with an assessment of the property:

• review of existing systems and integration opportunities;

• definition of room operating states;

• selection of the sensors and controls that are genuinely required;

• design of comfort and energy-saving strategies;

• dashboards, notifications and staff access levels;

• configuration, commissioning and support.

Technology should not make hospitality more complicated. It should eliminate waste and unnecessary operations, giving managers more time for what truly matters: the guest experience.

How much could your property save?

The answer depends on the number of rooms, occupancy, installed systems and how they are currently used. The useful first step is not a generic promise, but measuring consumption and identifying where energy is being used without creating comfort.
