Renewable energy: optimizing collective heating in condominiums in 2025

Collective heating is an essential component of comfort in condominiums, but numerous challenges remain. In 2025, faced with growing needs for energy efficiency and cost reduction, it becomes imperative to look into ways to optimize these systems. Managing uneven temperatures, excessive energy consumption, and slow reactions to problems are constraints that affect both occupants and managers. In this context, Efficap Énergie, with its innovative approach using connected and predictive solutions, stands out as a leader capable of transforming the landscape of collective heating. This article examines the flaws of traditional systems, Efficap's innovations, their outcomes, and offers advice on how to maximize the use of these new technologies.

The limitations of traditional collective heating in condominiums

For residents of apartment buildings, collective heating often represents a headache. Although convenient, this system has many shortcomings that affect both the comfort of occupants and the energy efficiency of the buildings. Over the years, experts like Hugo Corbille, president of Efficap Énergie, have identified several main challenges.

Lack of individual temperature control

Unlike individual houses, where each occupant can adjust their heating according to their preferences, collective heating systems inherently limit this capability. The lack of personal control leads to frustration and discomfort. Hugo Corbille states: “The occupant is not in control of their temperature as the heating is central and they have few levers for regulation in their apartment.” This feeling of powerlessness has implications for the overall energy management of the buildings.

Insufficient data for heating managers

Heating managers often conduct occasional visits, without real-time monitoring of consumption and temperature data. Unfortunately, these visits, which may occur once a week or once a month, are not enough to gather accurate and objective information. Hugo Corbille emphasizes that: “We lack objective measurements of what is happening in the condominium; we only rely on feedback from occupants, which is often too late,” complicating any effective intervention.

Poor placement of outdoor sensors

The accuracy of temperature readings is essential for optimal heating. However, outdoor sensors are often poorly installed, in 70 to 80% of cases. For example, a sensor located near a parking vent may provide erroneous readings by displaying inappropriate temperatures. This leads to significant imbalances. Let Hugo Corbille explain: “This type of problem, due to incorrect input data, can cause significant imbalances in thermal comfort.”

Ignorance of thermal inertia

Collective buildings have a certain thermal inertia, making it crucial to anticipate temperature variations. Unfortunately, traditional systems often respond to current fluctuations and do not take future forecasts into account. “By not regulating based on forecasts, we are constantly behind,” explains Hugo Corbille. Anticipating thermal needs is essential to avoid unnecessary overheating or underheating.

Late discovery of excessive consumption

Finally, the lack of real-time monitoring comes at a cost. Energy surpluses can reach heights of 10% to 50%, but often, they are only detected at the end of the season. This observation is one of the main concerns of homeowners, who find themselves with high energy costs without having been able to act in time.

Efficap: a predictive and connected solution for collective heating

In light of the observed limitations of traditional systems, Efficap Énergie has developed an innovative solution, Effic'App. This technology goes beyond simple manual adjustments, allowing for the optimization of collective heating by integrating connectivity, weather forecasts, and remote monitoring.

Measure to improve

The first pillar of Efficap is based on accurate data evaluation. By installing sensors in about 25% of the apartments in a building, real-time feedback is obtained. Thus, a reading taken every three hours can reveal imbalances in heat distribution. These capabilities allow for rapid action to prevent unnecessary surpluses.

Adjust to optimize

Once the data is collected, the Efficap solution adjusts the heating regulation directly from the boiler room. This eliminates the need for frequent trips by managers. As Hugo Corbille once again emphasizes: “Thanks to these measurements, we can intervene immediately and adjust the parameters according to the real needs of the residents, thus improving regulation and thermal comfort.”

Anticipate to save

The final aspect of the Efficap solution utilizes a predictive algorithm incorporating weather forecasts over 72 hours. Based on upcoming conditions, the system can preemptively adjust heating, thereby reducing costs while maintaining residents' comfort. This is a real advancement in collective heating management, enabling optimization of both comfort and energy savings.

Measurable results within the first few weeks with Efficap

One of Efficap's main strengths is the speed with which significant results can be achieved. The energy savings observed with this solution generally range between 12% and 22% within the first few weeks of use. Let's take the example of the La Fontaine residence in Antony, which adopted the Effic’App solution in 2024.

Results of the La Fontaine residence

This residence, comprising 906 apartments, has seen a stabilization of the indoor temperature at 20.3 °C. This has not only reduced energy surpluses but also allowed for proactive detection of issues such as faulty valves or poorly placed sensors. Jean-Marie Boisseau, president of the union council, states: “This solution has transformed our way of managing heating. We can now identify problems in real-time and intervene quickly.”

A well-deserved recognition for Efficap's innovation

The innovative response from Efficap Énergie has been recognized with numerous awards. Honored twice at the Trophée Coach Copro and during the Eco-Renovation Forum, this technology ensures its credibility with both occupants and managers. For example, the “Le Méridien de Paris” condominium was awarded for its energy renovation in 2019, attesting to the effectiveness of the Efficap system.

Tips to make the most of Efficap in your condominium

To optimize the benefits associated with the Efficap solution, it is crucial to involve all stakeholders from the beginning. Here are some practical tips to ensure a successful transition to a smarter heating system.

Involve all stakeholders

• Involve operators and syndics in the process right from the planning stage.

• Engage residents to ensure an understanding of the benefits of the solution.

• Organize information sessions to discuss the challenges of the transition.

Invest in a private network

To ensure service continuity and avoid dependencies on public networks, Hugo Corbille recommends the installation of a private antenna. “This independence guarantees total control over data and service continuity,” he emphasizes.

Train the operators

Understanding the tools and their functionalities is essential to fully benefit from Efficap technology. It is crucial to support operators with appropriate training so that they can effectively use these new solutions.

In summary, the Efficap solution redefines the approach to collective heating. Through a combination of technological innovations and optimization strategies, it not only reduces costs but also enhances the comfort of occupants. Energy management thus becomes a central concern, with positive consequences for the entire condominium.
