Noisy-le-Grand reduces its energy consumption thanks to artificial intelligence and innovation

The RECITAL project: reducing energy and carbon impact thanks to artificial intelligence

Noisy-Le-Grand is building a digital solution called "RECITAL" (for Immediate and Long-term Energy Reduction). Its aim is to reduce energy consumption and the carbon impact of its 200 public buildings, with a surface area of ​​around 200.000m², as quickly as possible, while optimizing renovation expenditure. Thanks to this new method for understanding usage patterns, the energy consumption of buildings will be reduced by 20% within 2 years and by 50% by 2030. Indeed, in the short term, the tool will "real-time" management of fluid consumption in buildings coupled with artificial intelligence to offer optimized solutions for both use and work. It will thus become possible to define the effective investment enabling the city to reduce energy consumption and its carbon footprint the fastest. RECITAL is built on the database standardized in the European NGSI format and relies on the city's data intelligence platform built in Open Source.

As of September 1, a first phase of development of the solution will be developed on 40 buildings (75% of consumption) to then be extended to the other 160 buildings 18 months later. During the work, the performances obtained will be evaluated and will be used to enrich the artificial intelligence solutions in order to feed the efficiency of the algorithm.

The RECITAL project represents a major step forward by integrating artificial intelligence, thus laying the foundations for a promising future where this technology will be deployed in various fields. At the same time, Noisy-Le-Grand has chosen to experiment with the project of the company Keski'a (Public spaces and urban services), offering young people a unique opportunity to familiarize themselves with this discipline of the future.

The Loiseau Lyre school: a revolutionary building with positive energy

For its part, the school group L'oiseau Lyre received the School Prize awarded this Thursday, June 22 on the sidelines of the official jury of the Regional Wood Construction Prize Île-de-France. It was the pupils of primary schools who chose L'oiseau Lyre, which will open in Noisy-Le-Grand at the start of the 2022 school year as part of awareness-raising workshops on architecture and biosourced materials.

The school reflects the concrete commitment to environmental sustainability deployed in the city. With 18 classrooms welcoming 462 students, this new structure with a total area of ​​6.245 m² stands out for its Nordic-inspired architecture and its avant-garde energy innovations. The construction of the establishment is based on the intensive use of wood from local sources, from sustainably managed forests. In its quest for energy self-sufficiency, the Loiseau Lyre school is equipped with photovoltaic solar panels with a surface area of ​​500 m², generating enough electricity to compensate for all the energy needs of the building. In addition, its green roof helps improve thermal insulation and promotes local biodiversity. The establishment also benefits from an innovative heating system based on a heat pump, powered by a network of geothermal probes. This solution provides comfortable heat to students while significantly reducing greenhouse gas emissions. In addition, in case of high temperatures, the system is designed to effectively cool interior spaces, thus ensuring the comfort of students and staff.

Finally, the Loiseau Lyre school was designed to promote access to natural light through innovative architectural devices. Interior spaces are bathed in natural light, providing an environment conducive to student learning and well-being.
