A role model in sustainability and energy efficiency: This is precisely why the top modern METRO wholesale market "ZERO 1" in St. Pölten, Lower Austria, received the EHI Energy Management Award (EWA) in 2018. The first zero energy operating building in Europe was awarded exemplary status in the category "Pilot branches" Energy efficiency / sustainability ". At the heart of the market is a sophisticated energy concept, which includes, among other things, particularly efficient and environmentally friendly refrigerated cabinets from Viessmann. The refrigeration specialists of the Viessmann Refrigeration Solutions Division have supplied and installed the entire refrigeration equipment in the plus energy market of METRO Cash & Carry Austria GmbH, based in Vösendorf (Vienna). The Viessmann sites Hof (Bavaria), Kesselsdorf (Saxony) and Porvoo (Finland) worked closely together under the auspices of the project specialists of kke GmbH Refrigeration, Air Conditioning and Energy Technology from Kesselsdorf, which has been part of Viessmann since 2016.
"ZERO 1" was already the third wholesale market of METRO Cash & Carry Austria GmbH, which the Viessmann Refrigeration Solutions Division has equipped with state-of-the-art refrigeration technology.
The internationally acclaimed flagship project "ZERO 1" was opened in October 2017 in the industrial park St. Pölten. The Viessmann specialists from kke took over the organization and installation of the entire refrigeration technology in the METRO market. A total of 90 Viessmann products ensure perfect cooling in St. Pölten. They score with their energy efficiency and, thanks to their stylish design, also set visual accents for the feel-good atmosphere in the market.
Particularly sustainable: All of Viessmann's refrigeration equipment uses only the natural refrigerant R744 (CO2). In addition, the waste heat from the refrigeration system feeds underfloor heating in the base plate of the market and thus heats the store. Also for the treatment of hot water, the waste heat is used.
Thanks to the 6,000 m2 photovoltaic system on the roof, the METRO market in St. Pölten is not only energy self-sufficient, but also produces more energy than it consumes over the year - making it a plus-energy wholesale market. The surplus of solar power flows into the e-filling stations in the parking lot of the branch.
