Circular construction techniques and a strong emphasis on reducing CO2 emissions are becoming increasingly important in real estate development. Lidl retailer in Germany is leading the way by adopting sustainable building practices for its new store in Wangen, featuring ORAÉ®, the first low-carbon glass by Saint-Gobain. ORAÉ® reduces emissions by 42% compared to Saint-Gobain’s European average for clear glass production. This is achieved through a high recycled glass content of 64%. For the store’s large showcase windows, COOL-LITE® XTREME 50/22 II solar control coating, deposited on ORAÉ®, was integrated into the wooden façade. The building also incorporates timber as a key material, allowing the structure to be assembled in just four weeks and enabling the use of highly efficient insulation. The wooden framework stores approximately 700 tons of CO2 in the roof, façade, walls and ceilings. In additional, the construction avoids composite materials, making it easy to disassemble and recycle all components in the future. The Lidl store incorporates energy-efficient technology, including waste heat recovery from refrigeration units to heat the building, reducing reliance on fossil fuels and supporting its DGNB Platinum certification target.
