Hello, here François, the dad of the écoquilles, who will try to answer the few questions asked on this forum. I do not know how to use a forum, I hope it's gonna be all right...
I invite everyone to go to my site,
www.pierre.verte.com, to better discover the écoquilles and to read there the answers to the questions which you ask yourself and which I will report there.
Okay, I'll clarify some points. First, the people and their respective roles. The company Efdé Innovations, which manufactures and sells ecoquilles, was founded by myself (see CV on my site) and has two partners, Martine, my companion in life who deals with the commercial relationship, and Pierre-Elie which helps me put my ideas into practice. Pierre-Elie is a little under thirty, he is convinced of ecology and trained in the design of wood constructions. He has created an eco-construction consulting firm, in his own name, which devotes almost all his activity to the Ecoquille. Pierre-Elie therefore participates in the design on the technical level essentially, but not that in practice too, the hand in the dough. He is so passionate about the subject that it takes two hours to fall asleep every night, to stir all the ideas we have, to draw the conclusions that our prototypes inspire us, to imagine developments for our concept. And when he wakes up in the morning, it is already with the Eco-head in his head, ready to work and to turn his mind. He seriously caught the virus! He is overmotivated and ready to put everything on the mat so that the Ecoquilles can grow. It's no longer a job for him, it's a priesthood, as for me.
Martine, she has other professional activities, especially for my editions of La Pierre Verte. But it is necessarily very involved in the Ecoquille project and is usually the relay of the reflections of our future customers. She is therefore responsible for defining their wishes, guiding them, advising them. The purchase of a house is a delicate and important business for everyone and Martine reassures, explains, demonstrates the overall coherence of our innovative habitat, while allowing us to take into account the suggestions expressed by those interested. We must also mention Laurence, the editorial secretary of La Pierre Verte, who puts a little order in our paperwork and helps me on various management points.
In July 2007, we hired two young employees, Clement and Hugues, to build and build our prototypes. Clement found the job too hard, too far from his studies. He was a bit young for such a job. Hugues, soon to be thirty too, received training on building and ecology. He likes the atmosphere in our company and that's what motivated him at first. But he too ended up falling crazy Ecoquille and he gets high on our sites to realize our common dream. He caught the virus, seriously, and he's still a passionate addition to our team, really passionate. Pierre-Elie and Hugues are happy to work on the Ecoquille because it develops their creativity and their skills. She also puts their work, their lives, in accordance with their convictions. They see it as a long-term future, a vocation. Fingers crossed for all of this to happen quickly.
And then, we have fans, sometimes fervent. Everyone has his way of acting and I think of Michel Marchand, the oasis of Bellecombe in the Drôme that moves heaven and earth for alternative housing, I think the team of the AES and François Plassard, who would like eco-hells of écocles, to Stanislas who gave us a hand, to Brigitte and Evelyne, first Ecocilian who made the realization of the dream possible by adopting it totally, to Jean-Michel, president of the association Ecorce who presents us everywhere on the occasion, not to mention our suppliers, helping hands and support (Aliécor, Aquabrasion, Ecolopole, Ecology and Heritage, Gino Zanin, etc) and now to Frédéric Thanron who proposed to launch a network or an association of ecoquiliens. I have not met him yet but he activates himself and the present post in this forum is the consequence.
So much for the actors and their roles, to avoid confusion and to thank them for what they are and do. Now let's go to the questions asked messages after messages.
First of all, inertia. Indeed, the shell has no inertia, and it is wanted. Inertia this represents the weight of materials, by nature, and we seek to lighten the shell as much as possible. In addition, those who have long lived in old mud houses (I am) know that the inertia is good in summer because we can capture the cool night but in general the effect fades after a few days, or two or three weeks, because always comes the moment when the inertia of the house is overtaken by the surrounding climate. In winter, the inertia of a dwelling makes it possible to smooth out the temperature differences due to the heating of this or that type, but it requires a lot of energy to be effective. For example, a wood-burning stove (I have one) has so much inertia that it starts to heat up two or three hours after you come home from work and brings comfort most of the time during the night, when we need it less. In a house with high inertia, it is necessary to heat constantly, moderately and with a lot of infrared radiation. That's why the old chimneys were so big. The embers radiated on a maximum surface to sufficiently load the walls. In the ecockpells, it is the insulation which plays a primordial role. Heating needs are very low for three reasons: a small volume of air to heat, no thermal bridge with the external temperature, walls that do not consume the energy inside, without any inertia. On the other hand we propose a type of very reactive heating, radiant heating mirrors, which bring all the necessary comfort. They will be so little used that we hope to heat our homes with very little electricity, so little that our houses will soon be the first to be heated by photovoltaic. We favored insulation because it is the only efficient, ecological, economic and sustainable way.
Another question: Louphil was worried about the renewability of the materials used in the shell and the "excessive" use of renewable resources from agriculture such as wood. So there, I invite those interested to read my book "I'm waiting for a house" which details the environmental consequences for each of the possible construction options. Regarding the eco-shells, the cork we use comes exclusively from recycling corks. It should also be noted that the cork oak plantations are currently underexploited in the world, practically abandoned in France, Morocco, Greece, Spain, Algeria, following a hegemonistic policy of Portugal in the matter. For other woods, knowing that France gains 30.000 hectares of forest each year, it would take tens of thousands of shellfish each year to stop this expansion of the national forest. This is all the less unlikely since half of the wood in the shellfish also comes from the recycling of shavings from the furniture industry. It would therefore be necessary for 100% of new construction in the world to be done according to our criteria for this to begin to pose a problem for the environment. For hemp wool, it is known that the cultivation of this plant is fast and without fertilizers or pesticides. Faced with all this, it is indeed plastics and other products derived from petroleum that are being exhausted and, precisely, the eco-shell is an alternative to avoid the crisis towards which we are advancing too fast.
Another question: the écoquilles are constructions too individual wrote another contributor, Gregconstruct. I invite you then very hard to read the little news that I laid, way fiction, and whose URL is
http://www.pierreverte.com/index.php?op ... Itemid=105. She explains in novelistic terms what I think of the trial that is being made to the inhabitants of single-family homes, an absurd and ill-intentioned trial, led by frustrated and jealous city dwellers (!), Victims and accomplices of shameless propaganda. big manufacturers (not less). And ecology must not be an excuse for the strangulation of our freedoms. As it is written in this forum, everyone dreams of a home to oneself. The big together, the rabbit cages, it is not suitable for anyone, not even rabbits. To complete, here are some orders of magnitude: if we take the world population and put two people per square meter, standing, do you think that takes place? Let's calculate: it's a half French department, hardly. And if we count a little less than 2 billions of human homes in the world, with 300 square meters of land for each, which is already quite comfortable, we arrive at an area of 550 billion m2, 550.000 square kilometers, the area of France in all and for all, this to accommodate decently all the inhabitants of the planet, each with its space to grow some vegetables, to compost, to store rainwater, to pose photovoltaic sensors, etc. Dear ecological friends, beware: the idea that rural people are big consumers of energy is pure propaganda. All calculations and serious and historical indices prove the opposite. Do not let us abuse. And for us, the ecoquille is precisely the best solution, given its low weight, to solve the questions of urban planning of the future. Grouped together in a hamlet, they are the only possible habitat for the well-being of both populations and the planet (well-being that we do not want to oppose to each other).
Another question: hability. Decidedly, dear Gregconstruct, you would have to come and see the results of our work before making your comments too theoretical and conventional. Because, indeed, we worked so much that we can affirm that an écoquille systematically presents 30 with 50% of habitability in more, compared to an ordinary house. We put sliding doors between the rooms, our radiators enlarge the space instead of consuming (mioirs), no useless corridor, no space boiler room, no combustible tank, no room for the cumulus, lighting specially designed to optimize interior spaces, etc ... We focused on the issue of livability to offer a home out of standard and much more spacious than another. In addition, all spaces under 1,8 m are not counted fiscally, which makes it even more economical. We also believe that it is useless to heat the corners of a house, the volumes under ceiling, etc.
Hence another question: ventilation. Here again, pay attention to propaganda. The current recommendations are given in the context of a habitat whose indoor air is dangerous. Obviously you have to air if you live in a polystyrene box (styrene is a violent neurotoxic) or if your heating needs oxygen. But in a shell the need for air renewal is limited to the breathing of the inhabitants, that is to say, very little. In addition, we have decided to separate the ventilation functions from the lighting function and we do not want to be aired by opening the windows. The windows give light and they are adjustable openings that allow ventilation. We take the fresh air to the north, below the shell, and the stale air escapes upwards, in the middle of the shell, by thermosyphon, that is to say without mechanical assistance. The advantage of this method is its energetic sobriety, its fine adjustment, its ease to couple with a Canadian well.
Well, I stop there. However, there is still plenty to write and we will do it. Amicologically, François
Ps: I read, following an internal debate at this forum : "Extremist behavior in defense of a cause (whatever it is) has unfortunately only rarely made things happen in the right direction. Quite the contrary ...." Let me say what I have to say. I think: I totally disagree with this sentence and I affirm on the contrary that only the most radical among us are able to make things happen. Descartes wreaked havoc in our brains like this desire to send everything back to back and no longer allow value judgment under the pretext of respect for others. Today, we are doing an article on wind turbines to praise their merits, and we leave the floor to EDF (via the association Vent de Colère) to make a counterpart, totally useless and dishonest. It is claimed that shepherds have serious reasons for not wanting bears nearby, when they earn ten times more from losing a sheep in its clutches than selling it to slaughter. All in all, we would like to put everything on an equal footing, and the value, the ethics, disappears. We say that Nazism and Communism are the same, etc ... We measure the usefulness of a project by its weight in euros, while investing in a hospital or an aircraft carrier has nothing to do with . Sorry but I do not subscribe to this false moderation and I affirm, like Goethe, that "Nothing great has been done on this earth without passion". I think if Gandhi had been intellectually French, he would never have existed. In short, I want to defend my ideas, and my actions, with my teeth if necessary. I know, this thought won't grow in the eyes of many. Well, too bad. I am not ready to water my wine when it comes to protecting the environment. I prefer those who are linked in front of the buldozzers in the Aspe Valley to those who dissert on the tone of such or such comment. The moderation that we would like to demonstrate, purely intellectual, makes the bed of generalized deception, manipulation, lies. And it is because of this hesitation in our convictions that the world is getting worse and worse. So courage and let's fight. Yes, let's fight ... There's no choice. It's a struggle. To pass the shell, the fight will require a lot more from me than the bit of thumb that I lost two months ago on a saw and the tens of thousands of euros that I had to take out of my pockets, without any certainty of return and at the risk of sinking my other professional activities. To do ecology today, serious and sincere ecology, that's a hell of a game. Let’s not imagine that this has become commonplace. It is not the new demagos for cars and the harmful return of heat pumps that can convince of a change in our society. No, I think, on the contrary, the fish are being drowned like never before. Again, I refer you to "Phase 2", my little novel that says a lot on the subject.
