Energy consumption in buildings accounts for around 40% of the total primary energy consumption in the EU 27 and it is considered that heat losses throughout windows and doors can be responsible for up to 25% of this consumption.
The environmental impact of the windows and doors is assessed by a life cycle analysis (LCA) that covers all the phases of the product - extraction and production of raw materials, assembly and transportation, use of the window/door, maintenance and end-of-life.
Green public procurement (GPP) is a process whereby public authorities seek to procure goods, services and works with a reduced environmental impact throughout their life cycle when compared to goods, services and works with the same primary function that would otherwise be procured. The EU Ecolabel is seen as one way in which GPP criteria can be met.
This is a scoping study to investigate exactly what an EU Ecolabel for windows and doors would comprise and how it would be assessed. The role of CWCT is to assist AEA in developing these criteria, as well as providing a commentary on potential future developments within the window industry that may reduce their in-use energy.
