Glass for Europe's Industrial Renaissance - Shaping EU policies 2014-2020

Glass for Europe, the association for Europe’ manufacturers of building,
automotive and solar-energy glass is proud to release its policy manifesto for the next mandate of the European Commission and Parliament. The document entitled “Glass for Europe’s Industrial Renaissance” sets out policies measures that need to be developed in the next 5 years to trigger the Renaissance of the European flat glass industry.

Window energy labeling in cooling season: fenestration and glazed structures - Study of existing labeling systems

Currently, USA, Canada, Australia, New Zealand and Great Britain have adopted systems for energy rating of the fenestration products. Among them, only Australia and New Zealand have taken into account the cooling performance. Finland has launched a pilot program for energy rating window products, while Denmark has developed a labeling scheme for glazing components.

Window energy labeling in cooling season: fenestration and glazed structures - Energy efficiency descriptors for labeling

The thermal and optical behavior of a fenestration system can be described with the following parameters:

• Thermal transmittance coefficient or heat transfer coefficient (U-value),

• Solar transmittance coefficient or solar heat gain coefficient (g value) - Shading coefficient (SC)

• Visual transmittance ( v ).

These parameters apply both for glazing and windows.
