First to achieve both BREEAM Outstanding + LEED Platinum: CO2 emissions 70% lower than comparable offices
Triple-layered high-performance glass allows in 70% of natural daylight but only 30% of solar energy – creating a “thermal envelop” made from 6 different types of glass
Ground source heat pump draws heat in from the ground outside, and during hot days, transfers it back outside – via 17km long network of buried pipes
All-electric: 5,000+ sq. ft. of solar panels – capability for surplus energy to be returned to National Grid
Established as workplace + visitor centre + think tank: fostering knowledge sharing and collaboration towards sustainable city solutions
Public ownership ensured for surrounding gardens and landscaped space
‘Community Strategy’ framework created: including educational workshops, local food programme initiatives, community gardening, urban beekeeping
Occupancy detection and comfort sensors adjust heat, light, and ventilation for optimal conditions
It is the UK’s first building to have an approved water safety plan – and is 90% self-sufficient in water supply. Rainwater is harvested from the roof via four corner node columns, stored in a 30,000L underground tank, and treated by filtration and UV. Moreover, 100% of blackwater (wastewater) is recycled for use in toilets and irrigation.
