Metro Cash & Carry Italy opened its first solar driven cooling system this summer. According to a press release of Metro Cash & Carry International, the Italian minister for economic development, Claudio Scajola, inaugurated the innovative, energy saving project in Rome. The installation uses solar energy to cool down the wholesale outlet during summer and to heat it in winter. With its 3,000 m2 of solar collectors – provided by the Italian Riello Group – this system on the store's roof is one of the biggest in Italy. “By installing the solar cooling system, we reduced our store's energy consumption by 12 % and can therefore cut down our running costs in Rome”, Dominique Minnaert, managing director of METRO Cash & Carry Italy, was quoted saying in the press release.
The solar thermal cooling system is based on technology and know-how from around the world. The system was designed by the British company AP Engineering Services. The chiller, with a power of 700 kW, was provided by the US-American Carrier Corporation, a leader in the areas of heating, ventilation, air conditioning and refrigeration systems. And the cooling tower came from Evapco Europe, a specialist for industrial and commercial cooling equipment with headquarters in Belgium and Italy.
The installation in Rome is part of Metro´s project “Energy Saving Today”. Its goal is to optimize performance of storage technology and therefore reduce energy consumption. In a first step, 30 locations will receive an upgrade until the end of 2008.
Metro Cash & Carry is present in 29 countries and has more than 600 self-service wholesale centres. With more than 100,000 employees worldwide, the company achieved turnover of around € 30 billion in 2006.
