Climate Protection SupermarketThe first energy self-sufficient store that produces more energy than it uses. Organic products and a healthy lifestyle are mega trends in our society and therefore in the food industry as well.When
building supermarkets, environmental friendliness and sustainability
are becoming increasingly important. Economically and ecologically
sustainable construction and operation minimize the ecological footprint
and reduce the life-cycle cost of buildings.This market is a 3rd
generation climate protection store with a gold certification from the
ÖGNI (Austrian Green Building Council). In fact, the site produces more
energy than the store uses, making it Austria’s first energy
self-sufficient supermarket.Architecturally speaking, the structure consists of a simple folded shell that arches over the triangular-shaped property.The
store opens onto the parking lot in all three dimensions, to the front,
sideways and upwards, which creates very broad and inviting entry from
this direction.On the south side, where the store tapers, a glass
façade offers a “front side” to the Floßlendplatz. This reinforces the
virtual effect of being drawn in and through the store and makes it
appear as an open, bright and friendly market place.The building
envelope itself features slight folds and wrinkles. This creates a
different effect from each perspective, and the building thereby
achieves a significant dynamic and tension: “like an athlete before
jumping.”For the façade, the goal was to create a strong haptic
quality with materials that convey the themes of climate protection and
naturalness, but also modernity and innovation.The façade consists
of galvanized sheet steel and wood. Due to their contrast, the two
materials convey the different themes, while also creating additional
excitement. The roof was designed as a fifth façade, with circular, hill-shaped green spaces.Climate protection store – technical implementation:In
order to achieve the goal of a climate protection store, a wide variety
of measures were necessary, which can be summarized in five large
areas:The highly-insulating building envelope minimizes both energy loss and energy input.The
building technology includes room ventilation, heat recovery and a
sectional foundation slab for cooling and heating; lighting with LED
technology and daylight control systems.The use of sustainable, separable and reusable building materials, preferably solvent-free and non-toxic. The
micro climate at the site. This means the creation of as many green
spaces as possible, including on the roof, which were designed to
achieve a hydrologic balance by leaching all of the surface water on the
property. In addition, the delivery area is enclosed to minimize noise
emissions.The energy generation. In addition, a photovoltaic power
plant is located in the parking lot, and a hydropower turbine will be
installed in the adjacent Mühlgang stream for energy generation. These
features create more energy than the store uses, and the excess energy
can be fed back into the grid.The overall result is an energy
self-sufficient climate protection store that offers an inviting
atmosphere for shoppers and a high-quality workplace for employees.
