Kaufland – Hristo Smimenski
Part of the German-owned Schwarz Gruppe, Kaufland has branches of its “hypermarket” chain in Eastern Europe, including in Bulgaria. Kaufland, which has a primary focus on food retail, is among the ten largest companies in Bulgaria, employing 8,500 people.
Kaufland has EDGE certified all of its markets built between 2006-2014, which typically each cost an extra US$100,000 as compared to a conventional retail building. It will take Kaufland on average just two years to recoup the investment, as the monthly energy bill for each store is projected to be reduced by more than US$4,000.
Kaufland is an ambassador of the EDGE brand within the retail space in Bulgaria, with nearly 50 of its stores now certified and plans for more stores to be certified in the future. In tandem with the certification roll-out, key assumptions were adjusted within EDGE as the Bulgarian government implemented tougher regulations. This ensured a tightly defined base case and brought confidence to Kaufland that its stores will perform more efficiently than peer buildings.
Predicted Savings of EDGE Certification
Reduced window to wall ratio, reflective paint and insulation for roof and walls, recovery of waste heat from the generator for space heating, variable frequency drives in AHUs, variable speed drives pumps, CO2 sensor/demand-controlled ventilation for fresh air intake, high efficiency condensing boiler for space heating, high efficiency refrigerated cases and energy-efficient lighting system.
Dual flush water closets, water-efficient urinals, and aerators and auto shut-off faucets.
Corrugated zinc sheets for roof construction, steel profile cladding for external walls and solid dense concrete blocks for internal walls.
*Part of the energy efficiency percentage may be associated with virtual energy for comfort depending on the presence of heating and cooling systems. Note that virtual energy does not contribute savings to utility bills.
