We hear it everywhere: The cheapest energy is the energy that is not consumed.
While the formula seems outdated, its logic remains relentless.
Today, businesses and communities must control their costs and their environmental impact. Technical solutions and regulatory standards are not enough.
The energy transition is also a human transformation.
Behind each kilowatt hour there are uses, habits and reflexes. These levers represent a great source of savings.
Without investment, adopting sober behaviors makes it possible to achieve 10 to 15% immediate energy savings.
There is no magic recipe.
These results are the result of the commitment of employees in a collective energy project.
So how do you mobilize your teams sustainably to reduce your energy costs?
Raise awareness, involve, promote: Sirenergie shares with you simple and concrete actions to transform energy sobriety into a federative and effective project.
Taken in isolation, each daily gesture can seem trivial.
But when combined, their impact is powerful, for better or for worse.
In a company, forgotten lights and standby computers quickly generate high and... avoidable expenses. Turning them off is a simple reflex that improves energy performance and reduces costs.
For efficient energy management, uses matter as much as technology. Inappropriate behaviors cancel out the benefits of efficient equipment. A very well-insulated building loses all its advantages if the windows remain open when the heating is on.
Conversely, sober and responsible practices give quick and measurable results. According to ADEME, simple behavioral changes can generate Up to 15% energy savings, without investment. Lowering by just one degree already reduces heating consumption by 7%.
Energy efficiency is therefore not only an environmental issue. Employee engagement is a direct driver of energy performance and cost reduction.
An efficient and sustainable energy sobriety approach goes beyond the imposed rules. It is part of a collective, positive and meaningful dynamic. Informing is not enough: you have to get on board, empower, make people want to act.
What's at stake? Transforming constraints into commitments around a collective energy project, where everyone contributes to energy management.
Apart from light, energy is invisible and abstract. Concrete figures give meaning to employees, strengthen their membership and value their efforts.
Visualize the evolutions Transform a technical subject into a concrete challenge. This involves:

With the Sirenergies Pilott application, transform your consumption into understandable data. Visualize savings, monitor progress and make energy a motivating collective energy project.

Identify volunteer collaborators in each department promotes the appropriation of energy sobriety.
These relay ambassadors - also called internal Energy Managers - play an essential role in the field to:
Their role must be clearly defined, recognized and valued, so that energy ambassadors are not seen as “impediments to going in circles”.
There is nothing like playing to transform a constraint into a positive dynamic.
With inter-service challenges, collective challenges and one-off competitions, employees become actors of change.
Source of emulation and cohesion, these fun formats generate quick, visible and encouraging results.
Challenge “zero unnecessary light”, “1°C less in my office” or “the most sober team of the month”, etc.: there is no shortage of simple and effective ideas to motivate and engage.
Businesses can also be inspired by — or participate in — national initiatives such as the Energy Fresco.
To change habits, nothing beats simple, visual and guilt-free tools.
Practical guides, fun posters and lists of eco-friendly actions in the office facilitate the adoption of good habits. Effective energy management is based on best practices simple, fast and adapted to business realities.
An example of a simple tool:
To last, sobriety must become a real collective energy project, part of CSR strategy and management culture. This involves:
Energy sobriety must become a unifying and positive project, which reinforces collective commitment.
Heating, lighting and digital uses are three of the main sources of energy consumption in businesses. The good news: the collective adoption of simple eco-actions quickly reduces their energy costs.
According to ADEME, heating represents around 50% of a company's energy consumption.
Maintain a stable temperature day and night, ideally at 19°C, is an effective energy management strategy. Conversely, lowering the temperature sharply at night is a bad idea.
As Emmanuel Sire, president of Sirenergies, explains,
“Going down to 15°C at night to go up to 19°C is like going up to 25°C, according to the principle of inertia.”
ADEME estimates that 40 to 70% of expenses related to lighting in companies are avoidable with simple actions and adapted equipment.
The advantage of lighting: it is visible.
Every oversight can be seen. Every good reflex too. It is an ideal ground for implementing good energy management practices.
Invisible, digital consumption is often underestimated. For example, a stationary computer that is in standby still uses 20 to 40% of the energy consumed during operation.
Even when switched off, if it stays plugged in, it continues to absorb around 70 Wh per day.
Compared to the entire IT infrastructure of a company, these residual uses represent a source of savings that is far from being marginal.
Extend lifespan equipment and limit unnecessary uses make it possible to significantly reduce the impact of digital technology.
Engaging your employees in energy efficiency means investing in the future of your company. By mobilizing your teams around a concrete and shared objective, you reduce your energy costs and strengthen internal cohesion.
Beyond the savings achieved, energy efficiency gives meaning, responsibility, motivation and federates. It places your company in a dynamic of global performance - economic, environmental and social -, to prepare for a more resilient, efficient and sustainable future.
At Sirenergies, we believe in the power of the collective.
Together, let's reduce your consumption, engage your employees and build sustainable energy performance.

To calculate Scope 2 emissions, use the following formula:
Energy quantity (kWh) × Emission factor (kg CO₂ e/kWh).
Use databases like ADEME for precision.

Même le bâtiment le plus moderne et le mieux isolé perd son efficacité si ses usages sont inadaptés. La technologie et les normes ne suffisent pas : la transition énergétique est avant tout une transformation humaine.
Derrière chaque kilowattheure consommé se cache une habitude.
Un collaborateur sensibilisé comprend qu'ouvrir une fenêtre alors que le chauffage est allumé ou laisser un ordinateur en veille consomme de l'énergie inutilement. En replaçant l'humain au centre de la stratégie de gestion de l'énergie, l'entreprise s'assure que ses équipements performants sont utilisés de manière optimale, garantissant ainsi une rentabilité durable et un impact environnemental réduit.
