How can IoT help reconcile energy performance and the overall well-being of users in the smart city?

Everyone agrees that buildings are designed first and foremost for the people who will live in them. For the well-being of the users, an optimization of the energy consumption is therefore essential. This is achieved at various levels, such as centralized management systems that save water and electricity, or reduce waste and improve the quality of sorting. It’s no secret that today’s smart city puts people at the heart of the digital transformation of territories. An investment in the Internet of Things and theSmart Energy will therefore enable the implementation of innovative technologies whose function is to facilitate the development of energy efficiency and the ecological transition.

User well-being and energy performance

Between home, transport and offices… A study has shown that we spend between 70 and 90% of our time in enclosed spaces. These figures provide food for thought for any smart city project whose objective is to reconcile sustainable development, energy efficiency and user well-being. Thanks to the new IoT technologies, meeting these challenges has become possible on several levels.


Since the Energy Transition Act was enacted, new buildings have been subject to the same objectives as renovations: to strive for positive energy and high environmental performance.

For this purpose, these new buildings are equipped with automated data management systems. The integration of these systems will allow for remote and real time control of consumption management, whether it be for air conditioning, lighting, gas, or fire safety.

All these energy solutions together form smart energy. Here are three concrete examples where the integration of the Internet of Things helps to meet the challenge of energy performance:

  1. RCx or recommissioning

The RCx is designed to re-optimize existing mechanical systems. By evaluating the real needs of the building through the study of electricity during the hours of occupation, the temperature of the rooms or the rate of humidity, this process will make it possible to improve the well-being of the occupants and to optimize the energy management.

The little extra? RCx allows for better integration of renewable energy. These include intelligent LED lighting, photovoltaic panels to replace gas, and rainwater recovery solutions.

2. Home automation

Home automation encompasses the techniques related to the control of a building and its atomization. In addition to being able to detect errors in real time, it allows you to anticipate them.

Combined with the IoT, it allows to optimize energy efficiency by controlling various connected objects such as thermostats, windows or household appliances.

3. BIM

BIM (Building Information Modeling) is the modeling of building data. This process is used step by step throughout the design, construction and use of a connected building.

In concrete terms, this process allows the data collected to be connected and optimized from a single analysis tool.

It is therefore possible to configure the energy management optimization process in a system where the different project actors interact in a continuous and interactive way.

The importance of data and the key role played by the Internet of Things in reconciling these two issues

In a simplified way, the function of the IoT can be summarized as follows: thanks to the storage and harvesting of data, it is possible to provide a service in line with the expected purposes.

Making an investment in the Internet of Things sector is a guarantee to increaseenergy efficiency through a combination of technologies that work under the umbrella of data.

Indeed, it will be a matter of collecting the data, then storing them and finally analyzing them. It is this data analysis and management that will enable smart energy actors It is this data analysis and management that will enable smart energy companies to apply remote control to equipment and optimize consumption management systems in real time, whether for gas or electricity, for example.

By modifying the physical environment based on this analysis, systems play a key role in reconciling the two issues of user well-being and energy consumption.

The key is to use this data ethically and in compliance with the standards in force.
