NSAI Agrément has introduced an independent Window Energy Performance (WEP) Certification schemefor the Irish consumer market. 

The WEP rating is provided for a standard window to represent typical window sizes. This enables a comparison between different products. Each WEP rating label is specific to a unique window frame and glazing assembly from a single manufacturer. This WEP label is non-transferable and both the window assembly name ⁽¹⁾ and the manufacturer ⁽²⁾ will appear on the WEP Certificate. The WEP Certificate Energy Index ⁽³⁾ combines the following characteristics to allow consumers to determine how well each window assembly will perform.
