The customer
Inaugurated on July 12, 2021, the Stade Océane is a year-round venue for sporting and cultural events. The first positive-energy stadium in France, it produces more energy than it consumes! However, its location above the water table and high capacity make it difficult to operate.
- Communauté urbaine du Havre: 54 communes, 275,000+ inhabitants
- Project start-up: October 2021
- Deployment at Le Havre's Stade Océane
The challenge
Le Havre Seine Métropole has more than 200 buildings to maintain on a daily basis: schools, health services, sports and leisure facilities, mobility solutions, waste management, etc. Equipped with CARL Source CMMS since 2016 for the day-to-day maintenance of its many facilities and installations, the community wants to go further in its approach to the digital transformation of its services: to facilitate the maintenance management of its building stock and reduce energy consumption.
The Stade Océane was chosen as the starting point for this new project: 19 hectares of facilities, a wide range of equipment, a variety of uses and audiences, and a complex architecture. On the one hand, its many facilities need to be monitored in terms of temperature and humidity levels (for electronic equipment), to ensure that air handling units are working properly and to check domestic hot water temperatures to avoid any risk of legionella. In addition, the stadium was built on a water table, which means that a pumping system is in constant operation to prevent the stadium lawn from being flooded… And only one technician is in charge of maintenance!
The conurbation has set itself ambitious targets for reducing energy consumption, so it monitors electricity, gas and water consumption to achieve them.
Our answer
Optimized maintenance also means reduced consumption on our actions!
To do this, we connect our BLPredict solution directly to the building’s BMS system, to collect energy consumption data reliably and on a recurring basis. In addition, we fit certain equipment with IoT sensors developed by one of our partners, the manufacturer Adeunis:
- COMFORT sensors monitor temperature and humidity in rooms containing sensitive electronic equipment
- SMART DELTA P sensors installed on ventilation systems to ensure smooth operation
- PULSE communicating sensors collect and transmit energy consumption data to the platform.
- The TEMP2S sensor and its two temperature probes, to ensure compliance with health regulations
Deployment
- Monitoring of water, electricity and gas meters
- Monitoring of 5 premises: temperature, humidity, carbon dioxide
- Monitoring of 4 air handling units, domestic hot water circuit and 3 lift pumps
- + more than 11K data/day
Some benefits
Detection of a water leak of ≃ 20m3/day
Optimizing boiler operation through cycle changeover
Inconsistency between electricity subscription and actual consumption highlighted
Ambient environment remediation by detection of carbon dioxide threshold exceedance
What next?
After only a few months of use, these initial results illustrate the impact of our BLPredict solution in reducing energy costs. These benefits are essentially the result of a better understanding of how certain equipment functions and malfunctions, and of a rebalancing through the renewal of practices better adapted to the complexity of this infrastructure.
The second stage aims to optimize maintenance management over the longer term, by developing processes for automating maintenance operations. To this end, the platform is continuing to learn and apply on a daily basis.
Last but not least, the focus is on customizing the dashboard interface to make BLPredict easier to use for all Le Havre Seine Métropole community technicians. A major objective is to extend the platform’s deployment to all the community’s buildings.
