Building for the future means: sustainability

Sustainability in architecture aims at energy efficiency and climate protection, and requires, first and foremost, the most economical use of natural resources. In future, a building’s sustainability factor will become an increasingly important assessment criterion for buyers and tenants, as well as a sales argument. This is particularly evident given the growing number of certificates for buildings, which evaluate sustainability according to set criteria. Below are some examples:

  • DGNB seal of quality (German Sustainable Building Council):
    This calls for integral planning plus the setting of sustainability goals, and takes ecological and economic factors into consideration.

    For further info:

  • Passive house certificate:
    Limits annual heating demand to 15 kW/h per m² of living area, so that a building can be heated exclusively by passive energy sources and needs no active heating system. To this end, the Passive House Institute requires a Uw value of ≤ 0.8 W/(m2K) for windows and glass façades.

    For further info:

  • Minergie standard (Switzerland):
    Assesses sustainability on the basis of set energy indicators for buildings, amongst other things. The Minergie label for windows, for example, is granted when a double casement window achieves the demanding insulation value of Uw=1.0 W/(m2K).

Aluminium is “utilised”, not “used up”

From the production of raw materials to recycling: aluminium is an ideal material for a maximum level of sustainability.
In recent years, the energy consumption of electrolysis has been reduced substantially in the production process.

Furthermore, only 5% of the original energy input is required for recycling. Thanks to the high quality of the material, products remain in use for a virtually unlimited duration, without requiring any complex measures to protect them against weathering, corrosion and fungal decay. And when windows need to be replaced after many years, the profiles will not end up in the hazardous waste site, but represent a valuable recycling source.

In the most important areas of application, the recycling rate of aluminium is between 95 and 100 per cent. Therefore, aluminium is generally not “used up”, but “utilized”, then reused time and again thereafter.
