Abstract or SummaryThe 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
Financial schemeRennes Metropole (conurbation in which Saint Sulpice belongs) invested in the LoRa infrasctructure

Long descriptionIn 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.

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.

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.

Good practice #5-2Raspberry Pi electricity monitoring and free software data collection
Main institution involved Municipality of Lorient
Field:
Energy monitoringX Financial monitoring

Abstract or SummaryThe city of Lorient wanted to set up a system for collecting and displaying the consumption and production of energy in its buildings. This in order to reduce energy consumption. Rather than using commercially available, proprietary, closed and expensive systems, it has chosen to use the world of free software.

Long descriptionThanks to its expertise in information systems and its expertise in electronic integration, Liberasys company responded to the market and was selected. After a phase of study, Liberasys defined upstream all that will be necessary in the long term for a project of this magnitude and then set about the realization of a prototype.

Liberasys has selected existing free components on the hardware and software level in order to reduce costs for the customer (the city of Lorient). The refereeing was not easy at the hardware level. Finally the Raspberry Pi platform was selected. The choice was confirmed by the results of this study: etude_single_board_computers_2016. In the end, given the latest information published on the security problems of the Internet of Things, it seems that the right decision has been made. Indeed, choosing a standard platform with a large community ensures the long-term update. This is a big plus for computer security and future software compatibility.

Liberasys has developed a software for decoding and interpreting the frames emitted by electricity meters of type PME/PMI (medium power >36kW). Were used code in Python, an object model, multi-thread, mutex, data persistence, a WEB API,… many technical challenges in short.

The result now allows real-time monitoring and archiving on the server of electrical consumption, solar panel production, temperature… a wide range of applications opens up for the city of Lorient.

As the solution is open, a shift to other interested communities is possible.

Abstract or SummaryFacing a dedicated and fixed budget, the municipality of Lorient found another way to develop renewable energies thanks to people’s financing. The city invested a first time in 2014-2015 in one of the school but is now working with citizens. Lorient mobilized a local organization composed of eco-friendly and aware citizens. From now on shareholders, the citizens created “Oncimè”, which means “let’s do it” to finance 174 solar panels in 2016-2017 an 106 new solar pannels in december 2017. Besides developing renewable energies, the 82 campaigners reclaimed the French energetic policy and steer it towards active democracy.
