IBIS CONFLUENCE HOTEL

Anticipate health risks by avoiding the spread of legionella

ID

The Ibis Confluence (ACCOR group) consists of two entities: Ibis Budget and Ibis Style, spread over a 7-storey building and containing 84 and 95 rooms respectively. Both hotels offer a wide range of budget hotels for business and leisure guests.

Market: French

Business sector: Hotel business

Type of building: Hotel

Objective: Monitor the building to optimize its operation and maintain a high level of customer satisfaction.

CHALLENGE

In any hotel structure, customer satisfaction is the priority issue.

Ensuring their well-being remains one of the main concerns for the director of IBIS Lyon Confluence. Among the elements to be considered are the maintenance and proper functioning of the hotel’s sanitary facilities, such as hot water networks (DHW).

Poor maintenance of these networks can cause the proliferation of the deadly legionella bacteria. The health risks for hotel guests are therefore significant. Controlling the non-proliferation of this is essential. Hotel structures (and more generally health establishments and establishments receiving the public) must take measures to monitor domestic hot water networks, control them and act as soon as possible if necessary.

As early as 2010, an order was issued requiring preventive and control measures to be put in place requiring hotel structures to maintain the temperature of the water between the point of distribution and the point of withdrawal at at least 55°C, the threshold below which legionella proliferates in the event of contamination.

The challenge for IBIS Lyon Confluence is to find a reliable and agile solution to control these networks.

SOLUTION

Wattsense, Adeunis and Energisme have implemented a turnkey solution that makes it possible to monitor, control and alert the evolution of the temperature of the hot water networks.

This solution is based on:

the adeunis TEMP 2S sensor,
the Big Data and IoT Energisme platform
the Wattsense communication system.

The TEMP 2S sensor is used to measure the water temperature at the flow and return of the heating circuit and to issue an alert when the temperature falls below the 55°C threshold.

The Wattsense system ensures the data transmission to the Energisme platform, which makes them more reliable, restores them and warns stakeholders in real time.

RESULTS

With this solution, the maintenance manager no longer has to travel, the control of the water temperature in the DHW networks is carried out remotely. It is informed in real time of any threshold overrun and can act as quickly as possible.

“With this solution, we ensure a high level of safety and comfort for the health of IBIS hotel guests.”
