Grâce à Genersys, la ville de Haguenau réalise une économie d’énergie de 15% dans ses bâtiments publics ! #2
The town of Haguenau has adopted Genersys’ Building Management System (BMS) to strike the right balance between thermal comfort and energy efficiency in some forty public buildings.
Benfeld, March 16, 2022 – Amidst the energy transition and rising fossil fuel prices, managing heating and the associated costs has become a critical challenge for the municipality of Haguenau, the second-largest city in the Bas-Rhin region, with a population of 35,000.” Confronted with a diverse array of heating systems to operate, maintain, and manage, the town of Haguenau selected the Building Management System (BMS) from Genersys, a leader in intelligent building and energy management within the E’nergys Group. This solution optimizes and ensures thermal comfort for users, while efficiently managing energy consumption based on building usage and occupancy.
Eric Girard, flow economist with the Communauté d’Agglomération de Haguenau, tells us: Thanks to Genersys’ BMS solution, we can now remotely monitor and control our buildings’ heating systems to enhance thermal comfort for our users, while minimizing overconsumption, waste, and the risk of breakdowns. This solution has enabled us to achieve energy savings of 15% in our public buildings.”
A turnkey BMS solution for exactly the right balance between thermal comfort and energy savings!
Confronted with a diverse range of heating systems and the increasing obsolescence of various sensors, the municipality of Haguenau decided in 2016 to completely overhaul its BMS, aiming to strike the right balance between thermal comfort and energy efficiency in its public buildings. For the city, the aim is to benefit from the latest generation of BMS, guaranteeing high-performance remote control and autonomous supervision, with no need for subscription, and in total security.
In addition to offering a technological solution that met the specifications set by the municipality of Haguenau, Genersys distinguished itself from competitors with its personalized approach, ensuring close proximity and responsiveness. Its comprehensive turnkey service, from PLC installation to remote support and on-site technician interventions, further set it apart.
Selected in 2016, Genersys installed the BMS sensors across the buildings in close collaboration with Haguenau’s technical services, which played an active role as stakeholders throughout the project. The installations were carried out progressively, aligning with the municipality’s renovation plans and priorities. The town of Haguenau aimed to remotely monitor and ensure thermal comfort in ‘sensitive’ buildings, starting with kindergartens, followed by those located further from the town center, and ultimately extending to complex facilities like the Nautiland water park.
Tangible benefits for energy efficiency and user comfort!
Today, Haguenau relies on Genersys’ BMS to remotely control the heating equipment in some forty buildings, from schools to sports facilities and the town hall. It has empowered the municipality to achieve energy savings of around 15% across all its sites. To ensure heating efficiency and user comfort across all buildings daily, the municipality of Haguenau can now use the BMS for remote maintenance in case of system performance issues. This allows for quick and easy resolution of even the simplest malfunctions. In the event of a complex heating system failure, the BMS solution allows the city to swiftly diagnose the cause, using key indicators from the field, such as valve opening rates, to address the issue promptly. This is achieved through close collaboration with Genersys and the relevant HVAC operators.
Over the past two years, the town of Haguenau has seen a drastic reduction in the number of breakdowns and downtime in its heating plants, which can cause thermal discomfort for users. Eric Girard completes the picture: “Genersys’ BMS seamlessly fits into our value chain for optimizing building heating, providing smart interconnection for daily management and enhancing the effectiveness and relevance of human intervention. In practical terms, this means that sensors installed on both existing and new boilers transmit accurate data to the information system, meaning that the right technicians can be identified for the task.” Another use for Genersys’ BMS is to remotely monitor and control the temperature of its IT server room to avoid “hot points”.
Eric Girard tells us: “In response to soaring gas and electricity prices, Genersys’ BMS solution means we can closely monitor heating usage across our buildings, maintaining an average comfort temperature of 22°C during the day,” he concludes. “In the event of an energy crisis, similar to those of 1973 and 1979, we have a valuable tool in Genersys’ BMS to achieve significant energy savings and move toward greater energy efficiency. For instance, we can adjust the comfort temperature based on building usage, should collective efforts be required.”
He concludes: “We have developed a strong relationship of trust with Genersys, marked by a collaboration that consistently meets our expectations in terms of responsiveness, proximity, and the active involvement of their team, from operators to technicians, in addressing our specific energy needs and challenges.”
