Energy reduction for smart buildings : how can S3EB play this role ?  

Introduction

The building sector accounts for a major share of electricity consumption and contributes significantly to peak loads on the grid.

With the rise of renewable energies and their production variations, the electricity grid needs greater flexibility. It is in this context that energy erasure, or demand response, takes on its full meaning: it allows the consumption of a building to be reduced or temporarily shifted during critical periods, in order to contribute to the overall balance of the power grid.

Smart buildings, equipped with sensors, control systems, building management systems, and monitoring tools, are particularly well suited to this approach. At S3EB, we see this development as a major opportunity: transforming buildings into active players in the energy transition and the Smart Grid*.

What is energy erasure ?

Energy curtailment consists of temporarily adjusting a site’s electricity consumption in response to an external signal, without compromising occupant comfort.

It can be automated thanks to the BMS, which manages uses such as heating, ventilation or lighting according to needs and times of day. This energy shedding avoids the need for additional means of production and stabilizes the network, while reducing costs for consumers.

With the generalization of renewable energies, this adaptability becomes an essential lever for energy performance. In France, erasure mechanisms are developing rapidly, supported by devices such as NEBEF* and the rise of aggregators for example Orus Energy, TILT Energy.

Smart Building and erasure : a natural alliance

Connected buildings already have all the necessary tools to implement erasure strategies. Their sensors, regulation systems and monitoring platforms allow real-time consumption adjustments, for example by slightly reducing the temperature or limiting ventilation over short periods.

This ability to react to network signals or price variations transforms the building into a dynamic actor, capable of actively contributing to energy stability while preserving comfort and business continuity.

A lever as economical

Beyond environmental interest, energy efficiency represents a real financial opportunity..

When a building participates in demand response programmes, it may receive compensation for the energy it did not consume during periods of grid stress.
These revenues come either from demand response operators, or from capacity or flexibility markets,depending on the contractual model chosen.

Concretely, this translates into :

• Additional income enhancing the erasure of the building;
• A reduction in overall energy costs ;
• A improvement in the return on investment of connected equipment;
• A strengthened image as an actor committed to the energy transition.

Energy demand response thus becomes a dual lever : ecological and economic.

The role of S3EB

As an expert in BMS and Smart Building solutions, we support our clients in implementing simple, effective erasure strategies adapted to their needs.

We start by identifying the shedding deposits and then evaluate theirpotential for valorization. We then integrate the erasure functions into existing supervision systems, in order to allow automatic and secure control of the relevant equipment.

Once the solution is in place, we ensure the continuous monitoring and optimization of erasure scenarios to ensure an optimal balance between savings, performance and comfort.

This approach creates multiple values : reduction of energy costs, regulatory compliance (Tertiary Decree, BACS) and improvement of the environmental image of buildings.

The S3EB products (GTB or BOS) allow a simple and fast implementation of an energy removal mechanism.

Don’t you have one of our products? This is not a problem, we can find with you the solution adapted to your site to allow you to be an actor in energy erasure.

Conclusion

Energy efficiency is no longer an option, but a new pillar of the Smart Building. It allows buildings to actively participate in the stability of the network while enhancing their energy efficiency.

Thanks to our technical expertise and our mastery of connected systems, we support companies in this evolution, making buildings not just simple consumers, but actors committed to the energy transition..
