sfide

● Apply a 360° ecological production systemand be sustainable not only in the content, but also in the 'containers'


Energy savings and therefore also of economic expenditure

description

The warehouse where the approx. 120,000 bottles produced per year are kept was self-built in green building, using for three walls the raw earth from the excavations and the straw from the fields cultivated by the cooperative, while the containment side is made of reinforced concrete.

The idea of building the room from scratch with this technique was born following the experience of the workshop building the “straw house”, used as a guesthouse, led by the architect Rodrigo Munhoz. The natural insulation offered by these materials makes it possible to maintain optimal temperatures for storing wines, without resorting to the use of energy-intensive air conditioners.

The development of the warehouse was coordinated and conducted by the engineer Alessandro Pasqualotto, a member of the cooperative.

 

In other workplaces, the commitment to avoid and reduce the waste of resources is divided into the choices of:

● use of natural sources, such as photovoltaic, to power cellar machinery;

● reuse the water used for washing, after decanting in tanks, for irrigating the garden and treating the vineyard.

considerazioni di ricerca

Limits to consider

• Straw earth is subject to greater wear and tear compared to traditional materials and requires maintenance (e.g. plaster is more susceptible to atmospheric agents)

• Straw may be affected by weeds

Potential

• Spaces built or renovated according to green building principles can be an integral part of the story about the wine that is produced, aimed at the public that visits the cellars.

• Reducing means saving, as well as reducing dependence on possible fossil fuels

description

Founded in the 70s by Ottavio Rube, Enrico Boveri and Cesare Berutti, Valli Unite is an agricultural cooperative that is based on a lifestyle in harmony with nature, with particular attention to healthy food, the place where you live and the people who populate this land. It stems from the desire to subvert the system that, at that time, forced people to leave their land uncultivated; and this is how this reality has grown exponentially thanks to many people who have united over time and who share its vision and values, laying the foundations for a place that continuously seeks a balance between tradition and innovation. Valli Unite is: restaurant, apartments, agricamping, production of wine (about 120 thousand bottles/year), honey, cold cuts, cereals and vegetables.
