The Beronia Rueda Winery makes its award-winning Verdejo wine with sustainability in mind. The production floor is below ground and enclosed by thick concrete walls for thermal stability and reduced air conditioning demands.
The facility uses a 50- to 60-kilowatt biomass boiler fueled by pruning waste to heat water, and the chilled water system has its own chiller with several cooling levels depending on winemaking requirements. For each water system, a 1,500-liter buffer tank significantly reduces the times the system stops and starts.
All heating and cooling generation and distribution equipment is insulated and includes variable speed fixtures to avoid unnecessary consumption. Rainwater stored in a 10,000-liter tank is used to water gardens and for toilets and cisterns, reducing overall water consumption. The used water is then channeled through a 1,500-cubic-meter storage pool for purification. Once purified using a twin Cascade filtration system, it is reused for watering the vineyards, closing the water cycle within the facility. Passive solar protection and natural light plus LED lighting regulated by photoelectric sensors increase overall efficiency.
