The energy transition of tertiary buildings, between new objectives and multiple co-benefits
In France, the tertiary sector comprises 940 million m² of buildings, i.e. 1/4 of all existing buildings. Offices, public services, education, hotels, restaurants, shops, airports... From 1990 to 2017, the surface area of tertiary buildings increased by 46% and the energy consumption of the sector increased by 29% according to the government website. Greenhouse gas emissions related to this consumption have increased by 8% per year. Faced with this climate challenge, the French government has put in place a new regulatory obligation resulting from the Tertiary Eco Energy Decree (Article 175 of the Élan). This imposes a gradual reduction in energy consumption in tertiary buildings of at least 40% in 2030, 50% in 2040 and 60% in 2050 (compared to 2010).
Kardham Digital: energy sobriety through intelligent building management Kardham Digital Kardham Digital
Between objectives and co-benefits of sobriety, the energy optimization of the tertiary sector meets a triple challenge: fight against climate change, reduce company bills and improve the working environment of employees.
Stakeholders need to control their energy consumption in order to make it efficient and sufficient for the proper functioning of their building. At the same time, major players in the sector, such as Kardham Digital, have the means to use the right amount of energy, thanks to turnkey, connected and controlled solutions.
Indeed, energy management is based on the collection and analysis of numerous data such as the presence or absence of people in a specific space, the temperature of spaces compared to the outside or the air quality of work environments.
By analyzing this type of information, smart building technologies control means according to the use of the building and this, in a completely automated way, without human intervention. The goal is to achieve economic performance because virtuous energy management is associated with a sustainable reduction in the bill.
Finally, the energy management of tertiary buildings makes it possible to create healthier and more comfortable working environments for occupants. The building is user-centric, responsive to the user's presence and adapts to their needs: optimal conditions to promote the productivity, health and well-being of employees.
Support from Kardham Digital for a commitment to energy sobriety
Kardham Digital was born from the conviction of the strategic nature of digital for a group such as Kardham, the first independent French group integrating all the business skills of the professional real estate value chain: consulting, architecture, design & build and engineering. Created in 2019 under the direction of Pascal Zératès, Kardham Digital brings together a wide range of skills around a team of 80 people spread between Paris, Obernai and Dijon.
As a subsidiary of the Kardham Group and a digital services company in the tertiary building sector, Kardham Digital's vocation is to make the most of the power of digital through 4 poles focused on uses:
- Smart Building
- Application Development
- Smart Workplace
- Audiovisual layout
Kardham Digital works daily to facilitate the deployment of digital technology in the tertiary sector. For the sector, this appropriation pursues three objectives following a service logic: ensuring the comfort of the occupants, improving energy efficiency according to uses and simplifying the operation of the building. This democratization greatly simplifies the interaction of occupants with the building via services such as:
- Reservation of spaces: parking spaces, meeting rooms of all types, workstations.
- Access to resources: dematerialized access badges, digital concierge, connected lockers.
- Comfort management: lighting, blinds, heating, air conditioning, ventilation, air quality.
The goal is to provide a 360° vision of the building to the operator, to meet economic and environmental performance challenges and to sublimate the user experience of the occupant, very different from that of working at home...
