Sustainability

Working on the details

Sustainability

  • Future project: Sustainability in the building stock. A manual is being developed for the sustainable operation of shopping centers, employee training and the creation of a sustainability benchmark.
  • District heating supply and green electricity reduce CO2 emissions — the conversion of most of the Deutsche EuroShop shopping centers to green electricity alone saves 23,400 tonnes of CO2 per year, on conservative calculations.
  • In the waste disposal process, waste is separated into paper/cardboard, lightweight packaging, glass, food remains and residual waste.
  • Green areas on roofs act as valuable biotopes in cities. They also help balance out fluctuations in temperature and further minimise energy consumption.
  • An intelligent drinking water and wastewater concept saves valuable resources.
  • The centers are ventilated exclusively via energy-efficient drives with low SFP (specific fan power) values. The large heat exchangers with a recovery rate of 70% reduce heating and cooling needs.
  • Intelligent control systems ensure natural ventilation via the roofs. This does away with the need for mechanical cooling systems, as the excess pressure in the shops is reduced and the cool night air is currently sufficient to achieve pleasant temperatures.
  • The areas for low-loss cast resin transformers are generally on the exterior walls, thus dispensing with the need for a separate mechanical cooling system.
  • Compact locations that have previously been developed reduce the amount of natural land that is lost.

Lighting

  • At night, emergency lights are deactivated via a time-delay switch.
  • In order to fulfil the requirements of modern design and sustainable utilisation of energy in equal measure, new LEDs have been developed for facade illumination.
  • Energy-saving lights, motion detectors and light intensities that change throughout the day all help to save electricity.
  • Solar control glass reduces the need for airconditioning and the intensity of light required in the shops.

Flexibility

  • Due to the fact that systems with a static design (no prestressed structures or continuous beams) and a sufficient load reserve are used, retail space can be divided up and redeployed with a high degree of flexibility.
  • Most locations are not greenfield, but rather brownfield sites. This means that no new natural land is lost. Comprehensive construction and groundwater surveys ensure that no problems of water table reduction arise and the land does not have to be decontaminated, which could be very costly.
  • The performance and consumption of the heating, ventilation and cooling systems are continuously checked and adjusted dynamically to current requirements by means of modern, computer-assisted control systems (DDC systems).
  • Reserves have been planned in the building’s technical systems for future changes of use. As part of this planning, power rails with a variable connected load are used as an energy supply system.

Construction activities

  • Detailed floor plans and logistics concepts are developed for each construction site to ensure that they operate as smoothly as possible. Where possible, sites are supplied and dispose of their waste by rail or waterway. We also check whether it is possible to use a static concrete mixing plant, with the aim of reducing traffic.
  • Special rubble collection points ensure that waste is separated right from the construction phase.
  • Enclosed construction equipment is used to cut noise and protect residents and workers on sites during the construction period.
  • Resources are conserved by means of reusable system formworks.
  • The use of durable German materials (marble from the Jura mountains, regional sandstone, domestic wood) reduces transport volumes. Unlike when materials from China, South America or Egypt are chosen, it is also guaranteed that the quarries will be recultivated.
  • The insulating material used for thermal insulation must meet the highest requirements. Foam glass, also known as cellular glass, is used in many Deutsche EuroShop centers. This material is predominantly made from recycled glass, which is ground, heated, mixed with carbon and expanded.

Surroundings & traffic

  • Our centers have good bus and rail links, making for convenient and environmentally friendly travel.
  • There are bike parking facilities for customers who cycle.
  • Inner-city locations reduce transport distances.
  • City locations also fit into existing structures and strengthen them.
