Case Study: Gilbert-Ash achieves real-time sustainability reporting and 99% waste diversion with SustainIQ

Gilbert-Ash Limited - Customer Case Study

Gilbert-Ash Limited used SustainIQ across its construction projects, including the Cambridge Mosque in Cambridge, Europe’s first Eco-Mosque built to achieve a BREEAM Excellent rating. The team needed a way to capture environmental, social, and procurement data accurately while supporting compliance, reporting, and sustainability goals on a complex, high-profile build.

Using SustainIQ’s platform, Gilbert-Ash recorded waste, energy, water, biodiversity, community, procurement, and people metrics in real time across multiple project roles. SustainIQ helped reduce weekly data compilation time by 75%, saved about 156 hours over the project, diverted 99% of waste from landfill, and showed that 61% of supplier orders were procured within 30 miles of the project, while also simplifying reporting for client, board, and audit requirements.
