In France, the building sector accounts for almost 43% of energy consumption and 20% of carbon emissions.
In cities, existing buildings, whether old or new, have a direct influence on the territory, resources and quality of life of the public in France, while also contributing to carbon reduction on an urban scale, according to a study carried out on building performance.
The effects on the environment are numerous: indoor pollutants, VOCs, CO₂, humidity, fine particles... all directly affect the health and comfort of the public, particularly in the densest areas where the environment is under pressure, in view of the current issues highlighted by every study on carbon and energy sustainability, in the move towards a moresustainablecityand a moreresponsibleworld.
Preserving a healthy environment then becomes a priority, as air quality, resource management and energy performance all depend on this fragile environment, whose importance for collective well-being and the overall view of city sustainability is demonstrated by every study, in themove towards a more balanced and responsible urban model, at the scale of each neighborhood.
The ecological city becomes a social, environmental and societal model of place, where every building, every place, every public space and every living space contributes to a collective sustainable building, designed for the well-being of the public, the quality of each space, the preservation of the living environment and the management of resources according to a coherent sustainability model and a global view of urban development, particularly in Paris.
Existing buildings play an essential role in this transformation: their renovation and adaptation determine the success of the ecological transition and the sustainable use of resources, following the model of a responsible city and a harmonious view of spatial planning, particularly in Paris.
Combining comfort and energy savings is now possible thanks to the use of IoT data.
Solutions such as Navixis and the Nexelec product range are part of this approach: they enable data to be collected, understood and acted upon, making smart buildings real players in the energy transition, real players in comfort and associated services in every territory.
The smart building offers a complete view of energy performance, a detailed view of day-to-day comfort and a global view of services dedicated to occupants in the territory, positioning buildings as real players in sustainability and global security.
The choice of materials used in these projects is decisive, as sustainable and responsible materials promote energy performance and the preservation of France's urban heritage, while at the same time being part of a history of know-how and innovation, following a sustainable construction model, in France.
Integrating existing infrastructures into this approach creates continuity between the past and the future, making existing complexes, designed with environmentally-friendly materials, the foundations of a more sustainable and balanced city in France, in keeping with the area's urban history, the French model of responsible development andthe occupants.
Buildings alone account for 43% of energy consumption and 20% of greenhouse gas emissions in the region's urban areas.
This makes it a key player in the energy and ecological transition, particularly in cities, where the concentration of activities accentuates energy needs and directly engages the public's responsibility in every area of life, territory and construction, where this commitment is fully materialized.
Every building becomes an essential lever of this transition, linking innovation, energy performance and respect for the environment, with a clearly materialized impact on the quality of the urban environment.
Urban construction is becoming a major pillar of urban transformation.
Every location, whether housing, offices or stores, is becoming an experimental space for rethinking consumption, energy efficiency, ecological sobriety and water management.
Stores, as spaces open to the public, play an active part in this transformation by integrating more sustainable solutions and responsible practices.
efforts to reduce energy consumption sometimes have perverse effects: in cities, modern buildings, better insulated and more hermetically sealed, trap indoor pollutants (VOCs, CO₂, fine particles, humidity...) in every living and working space in every neighborhood, modifying the very materiality of indoor environments.
Each space then becomes an enclosed area where air circulation is reduced, limiting the quality of ventilation necessary for the well-being of occupants in the neighborhood and influencing the materiality of perceived comfort.
As a result, while energy performance improves, indoor air quality can deteriorate, directly impacting public well-being and health, particularly in large cities where each neighborhood space is more confined and highly solicited, revealing the limits of thiscentury's current urban materiality.
So the real question is no longer just how to build sustainable buildings, but how to make existing buildings more sustainable, healthy and health-promoting in the heart of every city, to meet public expectations and preserve their living environment and configuration, including in stores.
This approach is part of a real urban history, that of the evolution of construction and building management practices.
Each city writes its own history of sustainability, in which health, performance and environmental responsibility become the pillars of a balanced future, nurtured by a collective imagination focused on innovation and based on the study of urban impacts.
This balance between innovation, ecology and collective well-being is played out in the city, at the heart of a profoundly ecological approach, adapted to the challenges of our century, including in stores.
Every city must become a model of ecological transition, where the quality of buildings and the health of residents are part of a sustainable, responsible and ecological vision of the city of tomorrow, designed for the current century and shaped by the imagination of sustainable development.
This ecological ambition redefines the way we design, build and live in the modern city, in line with the challenges of this century and the evolution of our common imagination.
Nexelec's solutions offer a concrete response to this paradox.
Thanks to the Internet of Things (IoT), it is now possible to measure and control building environmental conditions in real time, particularly in cities, in order to assess their impact on quality of life and energy performance.
Nexelec sensors collect precise data on temperature, humidity, CO₂ or fine particles in different types of cities and buildings, enabling a better understanding of the impact of uses on the environment and indoor comfort.
Intelligent technical management (ITM) places the building at the heart of a global performance logic: energy, environmental and human, thought out for the city and oriented towards the common challenge of sustainability.
In every city, every society, this approach links buildings, residents, infrastructure and transport to create a more resilient, sustainable city focused on ecological quality of life, supported by a precise and innovative technical vision.
This challenge hinges on the ability to combine technology, performance and environmental responsibility, while preserving the city's ancient heritage and urban fabric.
Responding to this challenge requires close coordination between local players to make the city a model of efficiency and sustainable balance, respectful of old buildings and the local architectural configuration.
Society is becoming a veritable ecological ecosystem, where the performance of buildings and technical mastery support the ecological transition and collective well-being.
This technical dimension strengthens the ability of cities to combine innovation, sustainability and quality of life.
Optimize energy consumption, based on measured data, by adjusting heating, ventilation or lighting systems according to needs, to better meet the challenges of today's world;
Preserve indoor air quality, thanks to real-time measurement, a major challenge in large cities and an increasingly urbanized world;
Improve the comfort, health and productivity of occupants thanks to a healthier environment, where every measurement enables precise action to be taken;
Anticipate future regulations and accompany buildings towards compliance, supporting the energy transition of tomorrow's cities through continuous performance measurement.
Nexelec solutions are part of this vision of energy performance: they enable buildings to reduce their carbon footprint while guaranteeing healthy indoor air and optimal comfort for the public, with a direct effect on well-being and the sustainability of spaces.
This measurable effect reflects the desire to design more intelligent environments.
Thanks to data and IoT, the paradox of the sustainable and healthy building becomes an attainable goal, for the benefit of public well-being and comfort, where energy performance , health and comfort are no longer in opposition, but complement each other in the same public logic of building sustainability.
This challenge embodies the desire to reconcile technological innovation with environmental responsibility.
The challenge of sustainable building nolongerliessolely in reducing consumption or emissions, but in creating a place that breathes, adapts and promotes the health of its occupants. A truly responsible place must combine energy efficiency, air quality,thermal, acoustic and visualcomfort.
By bringing togethertechnology, data and collective intelligence, each study helps us understand how the building becomes a living organism, capable of learning, evolving and maintaining a balance derived from the study of actual uses and needs, a virtuous balance between ecology, innovation and well-being, at the heart of a continuous study of performance and quality of life.
