ABSTRACT
Currently, in Europe, there is a constant effort to reduce the energy demand and carbon emissions for buildings. With 40% of the total energy loss of a building coming from its windows, the choice of good fenestration products can contribute to large energy savings.
The choice of fenestration products should not be solely made based on installation and operational costs, but rather on the global environmental impact and energy demand during the entire life span of the product. Because of this, the application of a Life Cycle Assessment (LCA) is necessary. The life cycle of a building window includes: raw material extraction, manufacturing of raw materials, distribution of materials, assembly of materials into windows, use and maintenance, disposal and recycling.
The window frame material has a significant impact on the thermal performance of the window. The window frames are commonly made of wood, aluminum or polyvinyl chloride (PVC). Each material has its advantages and relative shortcomings.
In this research, LCA is used to compare typical modern solutions for window frames. A state of the art review of current window frames configurations is made. For several window configurations, a comparative assessment is made. Conclusions are drawn related to the global environmental impact of each window frame type.
