Commercial real estate services firm CBRE was looking to use IoT solutions to improve remote operations of the SHELL service stations it manages in France.

CBRE needed a complete solution, easy to set up and use. To respond to this technical need, the Adeunis, Energisme, and Wattsense teams worked together to develop the most suitable solution possible.

SHELL, a giant in the petroleum sector, is committed to reducing greenhouse gas emissions worldwide via a CO2 action plan.

In 2017, the multinational company adopted a specific long-term objective: decreasing its energy product's carbon footprint by 2050, its first milestone, reducing 20% of its greenhouse gas emissions by 2035.

CBRE GWS supports SHELL in implementing this plan as the operator of all service stations in Europe (6000 sites in 17 countries).

An energy audit done at the service stations showed a lack of access to consumption data. As a way to recover the data for analysis and create an energy efficiency strategy, an IoT solution needed to be put in place. The IoT makes possible the introduction of new integrations to facilitate the management, maintenance, and energy efficiency of service stations, even at remote sites. One of the requirements for the solution was to centralize information between the different service stations for better optimization.




CBRE, alongside Adeunis, Energisme, and Wattsense, took the time to analyze the service stations and their activities to define the project's structure and establish the use cases. Though the initial purpose of the project was to detect possible use cases to optimize energy performance, after several exchanges, the teams realized they could also implement other solutions to improve the monitoring of equipment, maintenance, enhance the comfort of users, or even meet regulatory challenges.

As a proof of concept, the solution developed by Adeunis, Energism, and Wattsense was deployed on a pilot site: the SHELL service station on the A7 motorway in the Roussillon area (France). This first step aims to test the hypotheses made, analyze the first results, and decide, depending on the relevance of the information processed, of the model to be duplicated on the other service stations.

LoRaWAN Private Network

In this project, CBRE was looking for better signal quality on the site, scalability potential, the use of numerous sensors with reasonable battery consumption, respect of data confidentiality, and local data management.

To confirm the LoRaWAN network's coverage and guide the teams in the installation of the sensors, a site review, and a radio-mapping was carried out by Adeunis and CBRE. This study was done using a Field-Test-Device to measure the network's coverage at various locations.

Given the layout of the site, a basement, and two and a half floors, it was decided to use a private LoRaWAN network via the Wattsense Box to optimize coverage of the more than 20 data points (temperature, humidity, the opening of doors). With the information obtained from the test, the location of the sensors could be defined.


Using a private LoRaWAN network, CBRE can connect an internal management system without using the Internet and control its fleet of IoT sensors and its network infrastructure.

Heating Circuit Regulation

CBRE had to remotely access the temperature data of the heating regulators to verify that the heating setpoints were respected.

Siemens RVL 480 regulators use the closed communication protocol LPB (Local Process Bus) for data transmission. Being faced with closed protocols, such as LPB, can represent a real disadvantage for site owners and managers. Manufacturers offer only limited improvement opportunities and a range of expensive devices.

With the Wattsense Box, CBRE can quickly access RVLs to monitor temperature data and optimize heating circuits.

"The Wattsense solution allowed us to streamline subscription costs by centralizing all of the sensors on a single interface. This also allowed us to exploit already existing data from the boiler rooms by connecting directly to the machines and without installing additional sensors."

The deployment and installation of the entire solution were done at the pilot site. The solution consists of the following elements:

  • The Wattsense connectivity service centralizes building data and ensures the boiler room equipment communicates: two heating controllers (LPB) and 32 sensors (LoRaWAN). The installation was completed in one day.
  • Adeunis IoT sensors that collect and transmit data.
  • The Big Data and IoT platform from Energisme offers a dashboard and a decision support tool for all the management and optimization of the daily operation of SHELL sites.

The deployed solution is reliable and allows for qualitative data feedback. It saves considerable time because the data is available quickly and efficiently. It is no longer necessary to do trips to the site to get information.

  • Improved energy performance.
  • Reduced operational costs.
  • Improved user well-being.
  • Optimization of heating circuits.


Use cases:

1 - Monitoring of legionella / Limitation of health risks

  • Requirement: Read and control the DHW (Domestic Hot Water) loop's temperature to prevent the risk of Legionella proliferation.
    Since 2010, all public access buildings in France are legally required to control the temperature of the water present in their DHW circuits. The water must be kept at least 55 ° C between the distribution point, and the draw point. Below that temperature the deadly legionella bacteria can grow and multiply.
