naturally cooled 'groundfridge' is a sustainable alternative to refrigerated cellars

‘groundfridge’ by studio floris schoonderbeek takes form as a naturally cooled system for storing wine and food, serving as a modern sustainable alternative of the common refrigerated cellar. the spherical structure is dug in and covered with the excavated soil while only its door remains visible. furthermore, it requires no electricity, as utilizes the insulating capacity of the ground and the cooler night air temperatures.all images courtesy of groundfridge

studio floris schoonderbeek sought to generate a fridge that keeps products chilled in a sustainable way. groundfridge’s temperature persists stable throughout the year between 10 and 12 degrees, which is ideal for storing foodstuffs such as fruits, vegetables, cheese. meanwhile, for its installation, no permission is needed and no soil has to be disposed of during digging.

the inside part is clad in wooden shelves and smooth surfaces that make it feel more spacious. furthermore, the size is big enough for two people to comfortably stand within, while it is lightweight and pretty easy to be transported and installed. the entrance formed by sturdy materials is wide and high for users to walk in and out upright.

moreover, ‘groundfridge’ is provided with a battery-driven ventilator giving the choice of setting ventilation times to the desired specifications. inside, the temperature level matches the temperature of the ground outside, while is affected by local factors such as soil type, groundwater levels, exposure to sunlight, mound vegetation, and the average outside temperature. through top temperatures, an additional active cooler circulates and cools down the air inside.
