Passive can also play in collective buildings – Economy
“The feedback we received from people is that the building is quite ugly from the outside, but inside it is very pleasant, both in terms of the distribution of spaces and thermal comfort,” concludes Thomas Gelineau. He is one of four general practitioners serving at Coray Nursing Home, along with five physical therapists and a speech therapist. He is also one of the founders of the center. A care home in big stones like no other as it was passively tagged in December 2016.
“Economic building with fairly moderate added value”
There are no waiting rooms or overheated cubicles. “We’re never too hot or too cold, which is nice. The smallest sun brings us heat that we struggle to turn on our little electric convectors,” continues the doctor. Architect Jean-Charles Castric, who designed the care home, notes a bill of €500 per year for 400m2.
“In the beginning, we didn’t have the idea of a passive building. What was very important to us was the global space that allowed us to practice in common with other healthcare professionals and therefore cross-examine experiences. Jean-Charles Castric convinced us by proposing an economical building with a fairly modest added value compared to what a more traditional building would have,” says Thomas Gelineau. “We chose the lowest possible wall height on the facade to control costs. The ratio of developed area to closed volume is very good. We priced it at 1,520 euros including VAT/m²,” says the architect. It includes four-pane windows and integrated blinds on all four facades.
A large “modern and sober” administrative building
Quimper and Quimper Bretagne Occidentale hundred civil servants will put together at the end of February in the district of La Providence another scale very passive wooden facade building. Approximately 2,100 m2 of floor space and a total cost of €5.60 million. “Of course, additional cost at the start, but the promise of 90% energy savings and thermal comfort at work. It is a modern and sober place, one of the first of its kind in Brittany, as a symbol of our heritage policy in new constructions in the face of energy and climate challenges. There, the uses lend themselves to it, we won’t be able to go to new halls, for example, a more open one,” comments Françoise Dorval, Quimper’s elected official in charge of the environmental transition.
We are in the process of entering into collective self-consumption agreements to supply three industrial partners in the business area.
The designer and project manager is the local agency Brûlé Architectes Associés, active in the construction of bioclimatic or passive houses and buildings, with the most limited environmental and energy footprints. This firm embodies very well, Brittany, this belief can be passively reduced to great extents. His team also plans to integrate a new site in a 650 m2 office and residential building near Odet. With heating needs of 10 kW/m2/year.
“Totem Building for Industry”
On the industrial side, the Quimper headquarters of Entech Smart Energies, a specialist in the storage, conversion and management of renewable energies, has just received the Passif+ label from the Passivehaus Institute. The building, with an area of more than 3000 m2, houses a number of workshops, offices and platforms. Technical challenge to ensure hermetic, thermal comfort at all levels for 125 workers using mainly bio-based materials. According to architect Jean-Charles Castric, it costs 1,100 euros per m2.
“Founding director Christopher Franket had a dream to make it a totem building, a model for the industrial sector. The building is energy self-sufficient, generating electricity with photovoltaic panels on the roof and parking shades, so much so that we are in the process of entering into collective consumption agreements to supply the business area’s three industrial partners. “, summarizes Gaël Le Goc, the company’s CSR and communications manager.
