Aluminium recycling
The high intrinsic value of aluminium is a major economic incentive for its recycling. Indeed, aluminium scrap can be repeatedly recycled without any loss of value or properties. Furthermore, the energy required is a mere fraction of that needed for primary production, often as little as 5%, yielding obvious ecological benefits. A study by Delft University of Technology recently revealed aluminium’s considerable recycling potential in the building sector. Aluminium collection rates from a cross-section of commercial and residential buil-dings in 6 European countries were found to be in excess of 92%, demonstrating the industry’s commitment to sustainable development.

Intelligent buildings
Intelligent facades incorporating aluminium systems can decrease energy consumption in buildings by up to 50%. The key feature of these intelligent buildings is their constructive interaction with the exterior, markedly reducing heating, cooling, ventilation and lighting energy demands. This is achieved through numerous techniques and processes including photovoltaics, optimised ventilation mechanisms and appropriate light and shade management.
Sustainable construction
With the building sector coming under increased pressure to provide environmental performance data, the European Aluminium Association is developing Environmental Product Declarations (EPDs) for aluminium building products in line with international standards. An EPD is the most comprehensive and transparent type of environmental labelling, destined for business-to-business communication. It takes into account the whole product life cycle and computes a vast quantity of environmental information into a set of internationally recognised indicators, such as “use of primary energy”, “global warming potential”, “water consumption”, etc. It is, moreover, verified by an independent third party.
