insulation is a key point for modern comfort. But how to insulate an old building efficiently and ecologically? With hemp concrete: the hemp fibrous cell forming the "wood" of the hemp stalk, is used as insulation and coupled with air lime. The finish is a lime-hemp rendering. These materials combine technical, energetic, environmental and sanitary performances. The well-being of the occupants is thus ensured thanks to a healthy environment without chemicals and a humidity naturally regulated by hemp.

The wood industry has a central place in the economy of the Vosges department, especially for heating. Wood is a renewable and carbon-neutral energy when used with efficient equipment. We have equipped the house with a wood-chip boiler. This state-of-the-art equipment allows us to automatically manage the heating and hot water of the entire house. In the coming years, we plan to install a solar water heater that will work in conjunction with the boiler.

Why use treated water for watering and flushing the toilets? The ecological impact is not negligible. A 10m3 rainwater recovery system has been set up and allows a reduction in consumption of nearly 30%.

Also called phytodepuration, it is a new ecological solution for the treatment of wastewater. The wastewater is brought to successive basins in which the bacteria present in the root systems of the plants feed on the impurities. This system is effective and eliminates the periodic emptying of septic tanks or micro-stations.
