Sustainable construction

Phase 2A of the Gorlaeus Building has, like phase 1, been developed and delivered according to high sustainability standards. The building has achieved a BREEAM-NL Very Good certification.

Several measures have been implemented in the design and construction to reduce energy consumption and enhance comfort:

• Ground source heat and cold storage (GSHP/WKO) for sustainable energy supply
• Triple glazing for optimal insulation
• LED lighting throughout the building
• Approximately 1,150 m² of solar panels
• Highly insulated façades, roofs and floors (Rc value 6.0 m²K/W) to minimise heat loss

BREEAM

The building’s sustainability performance has been assessed using BREEAM, an internationally recognised assessment method for the sustainability of buildings.

Within Leiden University, the ambition is for all new-build projects to achieve at least Very Good, with a preference for Excellent where feasible. Phase 2A of the Gorlaeus Building aligns with this ambition and has achieved a Very Good rating.
