Sustainable construction

Just as in phase 1, phase 2 of the Gorlaeus Building will focus on sustainable building.

The key sustainable measures to be incorporated are:

  • Thermal energy storage system: a sustainable way to generate energy
  • Triple glazing
  • LED lighting
  • 1,150 m2 of solar panels
  • Façades, roof and floor installed to a high insulation standard (Rc is 6.0 m2K/W) to limit heat loss and improve energy efficiency


Phase 2 of the Gorlaeus Building will be, just as phase 1, BREEAM certified. Our ambition is to achieve a BREEAM score of Very Good. BREEAM stands for ‘Building Research Establishment Environmental Assessment Method’ and is a certified, independent method of determining a building’s performance in terms of sustainability.

BREEAM-NL evaluates a building’s level of sustainability using five potential scores: Pass, Good, Very Good, Excellent or Outstanding. This is the most wide-ranging sustainability certification system in the Netherlands and measures sustainability in 9 categories, ranging from the use of energy, water and materials to waste production and transport movements. BREEAM-NL was also incorporated into the development of phase 1 of the Gorlaeus Building. Phase 1 achieved a BREEAM Very Good score of 62.5%.
