What if your home became a zero -cost energy plant? In France, in the Drôme department, the retired engineer Olivier Sidler has created a revolutionary house: zero heating, zero bills and a stable temperature of 23 ° C all year round. But how is it possible? The secret lies in oneExceptional insulation and an ingenious heat recovery system.
The strength of this home is undoubtedly his highly insulating coating. The walls, with a thickness of beyond 50 cmare made with a combination of Rice straw, cotton, linen and hemp biofibmaterials that guarantee excellent thermal insulation.
The floor is equally efficient: one from the concrete rests on 25 cm of polystyrenepreventing all heat dispersion from the ground. The triple glass windowson the other hand, allow you to capture each ray of sunshine, naturally heating the internal environments. In addition, the house is designed with aorientation studied in detail: the large windows are strategically positioned for exploit solar energy in winter and, at the same time, keep the summer spaces fresh.
The warmth of the inhabitants and household appliances warms the whole house
How can a house without heating keep a constant temperature? The answer is surprising: The inhabitants themselves generate heat! Each person, with his own metabolism, emits about 80 Wattwhile the appliances in operation contribute further to heating the environments.
Thanks to a double flow ventilation systemthe heat produced is recovered and redistributed throughout the house, avoiding waste. Also, under the floor of the bedrooms, bricks in Terracruda They accumulate heat during the day and gradually release it during the night, ensuring constant thermal comfort.
A house that produces more energy than that that consumes
Not just this house it does not need heatingbut it is also one Small autonomous power plant. On the roof, 45 m² of photovoltaic solar panels generate double the necessary energy for domestic needs. Excess energy is resold to the electricity grid, guaranteeing An annual profit of about 2,300 euros.
Also for thedomestic hot waterthe system is highly efficient: i Solari boiler are activated exclusively in the sunniest hours, and a waste water heat recovery system It allows you to further reduce consumption.
Olivier Sidler’s project shows that A sustainable and autonomous home from an energy point of view is not a luxury for a few. The construction cost is in fact comparable to that of social housingmaking this solution accessible and replicable on a large scale.
