New Standard About Surface Energy Performance

In 2013, standard EN 16268 "Performance of reflecting surfaces for luminaires" was published, introducing the concept of maintained reflectance.


The initial reflectance class of a material doesn't take into consideration any deterioration of reflectance that might occur in service.

Reflectance Class Chart









Therefore, the reflective material shall be assigned a maintained reflectance class which gives an indication of the potential long term energy efficiency of the material in service. This shall be given by the lowest total reflectance value resulting from durability tests of:

  • Temperature
  • UV-exposure
  • Abrasion
  • Scratch resistance
  • Humidity

vega98 surfaces from Almeco accomplish all the requirements to be classified in the top energy class A+.
