St Sulpice Smart city - Rennes Metropolis

Who ?

Rennes metropolis realizes an experimentation of setting up sensors in the commune of st Sulpice la forêt.

Why ?

As a signatory to the convention of mayors, in the context of COP 21, the municipality is committed to reducing its energy consumption by 20% by 2020.

The energy and water consumption of communal buildings were analyzed and several points of improvement were identified:

-Have “real time” consumption indicators

-Identify leaks, or malfunctions as quickly as possible

-Control the heating of communal facilities according to their use

-Informing agents and users of the impact of their actions on the consumption of buildings in order to adapt behaviors

How?

In order to meet its energy consumption reduction problem, Saint Sulpice city set up a simple installation, requiring neither works and wiring: The deployment of a network of wireless sensors (with a very large Autonomy, 10 years on battery) allowing to study several parameters: temperature, water, gas and electricity. The data are collected and processed and the relevant information is returned, in the form of a dashboard, through an application. The equipments ( air conditioning, heating, light ) can also be controlled remotely. In addition, in case of anomaly (for example a water leak), the application send an alert allowing to act quickly. It is the alliance of the start-up Wi6Labs and the companies Alkante and TDF, which made it possible to develop this simple solution of installation, use and maintenance.

How many ?

The assistance of the Brittany Region, Ademe and Rennes Métropole has been necessary for the project. The experiment during 18 months, within the framework of the innovation aid Rennes Saint Malo Lab. In this project the municipality is a territory of experimentation for the two companies Wi6Labs and Alkante. The objective is to validate that the solution implemented allows us to reduce the energy consumption of buildings by at least 20% (savings of 10,000 € per year) and to have a return on investment less than 5 years.

conclusion

With the data collected, the municipal team will be able to define an energy optimization strategy. In addition, the savings will enable the city to get involved in other projects. The city of Saint-Sulpice-la-Forêt opens the way to a multitude of “Smart Village”, which should appear in the years to come.
