šŸŸ© GreenBricks Building of the Week šŸŸ© One Angel Square

Sliced-egg green


One of the largest to ever achieve such green credentials, this building is not about environmental add-ons or eco-bling wind turbines: sustainability is truly integrated into the structure.

šŸŒ±Sustainability

  • EPC A+, BREEAM Outstanding (95.3%) = world-record at the time

  • Fully glazed double skin faƧade with louvred panels ā€“ insulates in winter and facilitates ventilation in summer

  • Cogeneration heat and power plant uses biofuel and rapeseed oil, sourced from local Co-op farms = energy-plus building

  • Heat recovery from IT systems helps to heat building

  • Greywater and rainwater recycling systems for toilet flushing + irrigation


šŸ„¦ Wellbeing

  • Integration into public transport links, easily accessible by cycle routes; 105 on-site bike stands

  • Soaring open atrium flooded with natural light; reflected by white painted concrete reduces need for artificial lighting from 500 to 330 lux

  • Roof top and extended public area planting

  • Construction involved a high level of community engagement: 900+ people benefitted from on-site training, engagement with 1,000+ students, and 54% of workforce from Greater Manchester area



šŸŽˆBonus feature

Itā€™s future proofed against temperatures forecasted for 2050 ā€“ meaning it can cope with a potential 3-5 degree increase plus 30% more rainfall. The building becomes more efficient as global temperatures rise. Now thatā€™s forward-planning.
