Located in St. Helena, California, the 30,000 SF wine production and barrel storage facility has been designed using the latest and most advanced version of the Energy Mass™ Smart Building Technology. Photovoltaics located on the roof make ice during the day with the power of the sun which cools the building’s interior using a computer controlled radiant refrigeration system. The ice will be stored in an Energy Mass™ ice tank measuring 22 feet by 40 feet by 17 feet tall. Silent and efficient, the technology is designed to produce a steady 58° F without drying effects, resulting in an estimated 1% evaporative loss from the wine barrels. The low energy demands required to run the cooling system gives the option for the winery to disconnect from the electrical grid. According to several independent sources this will be one of the greenest wineries in the United States. The winery is scheduled to break ground on construction in the Spring of 2020.
