Owner approach of sustainability

The Sustainable Development House is a concrete example of a comprehensive sustainable development approach, which integrates advanced technologies and environmentally friendly practices. The building is an exemplary building in ecological and energy terms, designed to produce more energy than it consumes, thanks to a photovoltaic installation, a SMARTFLOWER and a Windbush. The thematic rooms and workshops equipped with the educational platform allow an interactive and experimental experience of learning the different themes linked to sustainable development. Thematic rooms, such as the Biodiversity room, the Water-coastal room, the Circular Economy room and the Energy Efficiency and Renewable Energy room, offer a complete immersion in the concepts of sustainability. The building also incorporates environmentally friendly technologies, such as a Canadian well to regulate indoor temperature, a STEP wastewater treatment plant, a rainwater accumulation plant and a composting unit. The open-air space includes an educational lake, a botanical garden and a renewable energy discovery area, which helps raise visitors' awareness of biodiversity, coastal preservation and renewable energies. The building design was carried out with advanced tools such as dynamic thermal simulation, dynamic energy simulation and daylighting simulation. The House of Sustainable Development is an inspiring example of how technological innovation can be combined with environmentally friendly practices to create an educational and sustainable space that strengthens the human capital of the population in terms of sustainable development and energy and ecological transition.

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.

• Renewable energy production : 291,00 %

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.

Solutions enhancing nature free gains :

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

• GHG in use : 1,76 KgCO₂/m²/an
Methodology used :

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.

Comfort

Health & comfort :

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.

Calculated indoor CO2 concentration :

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.

Calculated thermal comfort : 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

Measured thermal comfort : 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.

Daylight factor : 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.
