Architectural description

The MDD building exemplifies sustainable bioclimatic architecture, an innovative approach to reducing energy costs and environmental impact while creating a comfortable living environment. This design uses techniques to optimize the use of natural light and solar gain in winter, while limiting the latter in summer. Windows are strategically placed for deep penetration of natural light, while walls and ceilings reflect and diffuse this light to create a warm ambiance. Eco-friendly and sustainable building materials are used to reduce the overall environmental impact. Additionally, the building has high insulation and low air permeability to maximize energy efficiency.

To complement these features, the building also uses a Canadian well system to preheat incoming air in winter and cool it in summer. This system is extremely efficient and can significantly reduce the energy consumption required to heat or cool the building.

If you had to do it again?

If we had the opportunity to redo the construction project, there would have been a few changes we would have made. First of all, we would have carried out a CFD (Computational Fluid Dynamics) simulation to better understand the air flow in the hall and optimize natural ventilation. Then, we would have increased the depth of the Canadian well for better regulation of the interior temperature. Finally, we would have started studies for HQE (High Environmental Quality) certification from the start of the project, which would have made it possible to certify the building and attest to the principles of sustainable development used in construction.

Building users opinion

As an occupant of the sustainable development building, I am very satisfied with the thermal comfort, light, acoustics and atmosphere in the building. Everything has been designed to create a pleasant and healthy working environment.

The climate well heating and cooling system is very efficient and maintains a constant temperature throughout the day. Windows are designed to maximize natural light while minimizing heat in summer.

The acoustics in the building are also excellent. Workspaces are designed to minimize noise and noise pollution, allowing you to work in a calm and focused environment.

Finally, the atmosphere in the building is very pleasant. Workspaces are spacious and comfortable, with plenty of room to move around and interact with other building occupants. There is also plenty of green space and plants inside, which helps create a relaxing and natural ambiance.

Overall, I am very happy to work in this sustainability building. It is clear that a lot of thought and effort has been put into the design of the work environment, and this results in a healthy, enjoyable and productive workplace.

Energy consumption

  • 85,00 kWhep/
  • Other

  • 8,88 kWhef/
  • In buildings, the consumption of office equipment represents the majority of energy consumption. However, the House of Sustainable Development stands out for its innovative bioclimatic architecture, which eliminates the need for heating or air conditioning, while providing optimal thermal comfort to its occupants. This unique architecture also significantly reduces the use of artificial lighting by maximizing the use of natural light in interior spaces. With a high rate of self-consumption of renewable energy produced on site, we were able to drastically reduce primary energy consumption.

    We have a self-consumption rate of 88%

  • The House of Sustainable Development is a positive energy building which produces three times its annual consumption, i.e. a production of 37,769 kWh. Of this production, 11,400 kWh are self-consumed, which represents a self-consumption ratio of 88%. This consumption is supplied by three systems:

    Photovoltaics, which generates an annual production of 29,203 kWh;
    The Smartflower, with an annual production of 5,678 kWh;
    The Aeroleaf, which produces 2,964 kWh per year.
    These three systems therefore make it possible to produce enough energy to cover the needs of the building, while providing a surplus of electricity to resell on the network. In addition, the high rate of self-consumption demonstrates the effectiveness of the energy management system of the Maison du Développement Durable.

    We promote the use of energy-efficient equipment in our building, as well as natural lighting to reduce artificial electricity consumption. For example, we use devices such as the Canadian Well to passively heat and cool the building using energy from the ground. We also installed a solar water heater to reduce our domestic hot water consumption.

    Finally, we optimize our energy consumption by using natural ventilation. This solution helps maintain good indoor air quality while reducing energy costs associated with air conditioning.

    In summary, our building is equipped with energy-saving solutions such as natural lighting, Canadian well, solar water heater and natural ventilation. This allows us to minimize our environmental impact while reducing costs associated with energy.

GHG emissions

  • 1,76 KgCO2/m2/an
  • Greenhouse gas (GHG) emissions linked to all energy consumption are 1.76 kgCO2/m²/year. However, the use of renewable energies has made it possible to considerably reduce these emissions. In fact, self-consumed renewable energy makes it possible to avoid 8 tonnes of CO2 emissions per year, while injecting green energy into the network makes it possible to avoid up to 19 tonnes of CO2 per year.

    The House of Sustainable Development promotes natural lighting to ensure optimal comfort for its occupants, while using interior protection to reduce glare and improve comfort. For thermal comfort, bioclimatic architecture is favored to maintain a pleasant temperature in the different rooms. In addition, the use of a Canadian well makes it possible to further improve thermal comfort by blowing heated or cooled new air. This device also helps improve indoor air quality by filtering pollutants and evacuating excess humidity. Thus, the Canadian well contributes to a healthier and more comfortable indoor environment for the occupants of the Sustainable Development Center.

    Les simulations en salle ont été réalisées à l'aide de l'outil de simulation du QAI de la CNRS. Elles montrent que la concentration de CO2 ne dépasse pas 1300 ppm et reste inférieure à 1000 ppm pendant plus de 80 % du temps lorsque les menuiseries et les portes sont fermées. Toutefois, en réalité, lorsque les menuiseries sont ouvertes, le renouvellement d'air par ventilation naturelle améliorera davantage la qualité de l'air intérieur en réduisant la concentration de CO2.

    L'ensemble des simulations a été réalisé avec Pléiades Comfie, en se basant sur les normes ISO 7730 et 15251, et a abouti à un taux de confort simulé moyen de 84,63 % dans les bâtiments. Tous les détails concernant chaque salle sont présentés dans le doc

    Des capteurs de température ont été installés dans les salles principales pour mesurer la température et évaluer le confort thermique. Les résultats montrent que le pourcentage d'insatisfaits varie entre 8 % et 12 % dans ces salles.

    Le bâtiment dispose d'un facteur de lumière naturelle supérieur à 1,5 dans 73 % de ses espaces, à 2 dans 65 % de ses espaces et à 4 dans 50 % de ses espaces.

    Smartflower is a photovoltaic solar panel system that tracks the movement of the sun throughout the day to maximize solar energy production. The system is designed to be installed outdoors on a flat surface, such as a patio, garden or roof.
    The operating principle of Smartflower is relatively simple: the system automatically deploys in the morning and follows the sun throughout the day, orienting its solar panels towards the sun. The panels are arranged on petals that open and close depending on the location of the sun in the sky.
    The system uses solar sensors to detect the position of the sun and electric motors to rotate the petals in real time. Solar panels are arranged on the outer surface of the petals, allowing Smartflower to collect more solar energy than conventional solar panels.
    The main advantage of Smartflower is its ability to maximize solar energy production, thanks to its ability to track the movement of the sun throughout the day. As a result, it can provide more solar energy than fixed solar panels, reducing electricity bill and minimizing environmental impact. Additionally, Smartflower is designed to be easy to install and use, making it an ideal solution for home or business owners looking to produce solar energy conveniently and efficiently.
    the SMARTFLOWER meets part of the building's energy needs by producing 5,872 kWh annually

    Canadian Well

    Génie climatique, électricité / Ventilation, rafraîchissement

    The Canadian well, also known as a passive geothermal system, is a passive air conditioning system that uses geothermal energy to heat or cool a building. It works by using the constant temperature of the ground, which is generally colder than the outside air temperature in summer and warmer in winter. The system uses a buried duct, called the Canadian well, to exchange air between the exterior and interior of the building. Outdoor air is drawn through the Canadian well and is preheated or precooled by the ground before being distributed throughout the building through ducts. The system can be used in combination with other heating or cooling systems to improve the overall energy efficiency of the building. The Canadian well is considered an ecological and economical solution for heating and cooling buildings.
