to shine a beacon of fossil-fuel-free light itself. Originally intended to reach BREEAM Excellent, it became the world's first building to attain both BREEAM Outstanding and LEED Platinum ratings over the course of the project. Generating 20% of the building's electricity, two thirds of the roof is covered in PV panels; the remainder is a green roof consisting of plant species proven to sustain local wildlife. Ground-source heat pumps supply 100% of the building's heating needs and most of its cooling. Eighty-four percent of hot water is enabled through the PV and heat pumps. No fossil fuels are burned here at all. The Crystal is also ready to be connected to the smart grid, and the BMS is central to all building operations (heating, cooling and ventilation; lights and blinds; sensors that detect occupancy levels; safety features; and even an outdoor weather station), collating data from 12,000 control points. Not a drop of water is lost throughout the building. Rainwater is harvested and recycled or reused -- 90% of potable water demand is technically possible through treated rainwater alone. One hundred percent of blackwater is treated and reused for irrigation and flushing lavatories. Of course, there's a dedicated waste recycling area too. The Crystal's office space is designed to use on average 83kWh/m2/year (less than 50% of the energy use of comparable office buildings) and generate 65% lower carbon emissions too. And all this created on a tight schedule in a waterfront city location. Buildings like this show what is
