20.12.2009 REWE Green Building
In October 2009 the German Sustainable Building Council (DGNB) awarded pre-certification in gold to the "REWE Green Building - Concept Future". That store is one of the first sustainable and CO2-neutral retail trade buildings in Germany to receive the "German Seal of Approval for Sustainable Building" in gold. The seal has been developed by the DGNB and the Federal Ministry for Transport, Building and Urban Development. Thanks to the ground-breaking use of state-of-the-art heating, ventilation, lighting, air-conditioning and refrigeration systems, combined with the best possible insulation, the Green Building's energy consumption has been cut by almost 50 percent compared to a standard building. In the normal refrigeration and the combined refrigeration and deepfreeze systems, which cool fresh products and deepfreeze assortments, natural refrigerant is exclusively used. The REWE store in Berlin produces around 40 per cent of its own energy requirements. The photovoltaic system measuring almost 2,000 square metres combines a large roof-top unit made of special cylindrical modules - which collect the sunshine on a 360-degree surface and are hence particularly energy efficient - with a photovoltaic unit integrated into the glass of the projecting part of the roof. This not only provides stylish design features but also at the same time provides natural shading for the large window surfaces.
Twelve bore holes in the ground, each reaching depths of almost 100 metres, were required to create a geothermal energy plant, which makes the use of fossil fuels superfluous throughout the whole year. The REWE Green Building incorporates the principle of daylight architecture, which has up to now scarcely been used in the German retail industry: this is implemented through a 280 metre long window façade running around the full length of the building and 18 cupolas providing light through the roof. This daylight architecture is combined with optimum insulation (cellulose) and sustainable materials, such as wood. ( More information; More information/German;)

15.10.2009 Students push Sustainability
Prof. B. Hallier discussed the systematic of an Environmental Retail Management with students of the Alanus-University/Germany . Their seminar is dealing with sustainable distribution.
Students are not only listening but actively supporting this topic. Above the horizon of their own university some of them are actively involved in the internet via www.i-ev.de (student club for sustainability), www.studierenfuermorgen.de (study for tomorrow),
www.tagderideen.de (day of ideas). On their own campus they are organizing their second dialogue with industry; the slogan of those dialogues is W.in.d (Wirtschaft neu denken: translated: rethinking/re-inventing business/More)
