Harvard green buildings conserve enough water to fill five of these pools each year.
Harvard just earned itself one more (green) distinction this week with its 20th LEED certification, more than any other university in the world (and more than the rest of the ivy league combined. Take that!). The Zhuang Lab was the happy recipient of green renovations and upgrades, and helps the school save a total of $680,000 in utilities annually.In total, the University has 3 platinum level, 9 gold level, 4 silver and 4 certified level of recognition buildings across campus. They've certified the oldest building in LEED (built in 1889), and the first LEED Platinum Commercial Interiors and LEED Platinum for Homes. In total, the 20 buildings cover over 1,000,000 square feet of space and conserve the equivalent of 5 olympic sized swimming pools full of water, or in other words 3,500,000 gallons of water each year.
The Zhuang Lab upgrades also focused heavily on energy efficiency to achieve its status. "Fume hood face velocities are set at a low but safe levels to conserve energy" and data is displayed in real time which serve as a reminder to keep hoods closed. The HVAC system was sized to match space load, and all lighting is adjusted due to daylight sensors and occupancy sensors. Systems are checked constantly so that problems and inefficiencies are caught and fixed quickly. Green power was also purchased to offset one year's worth of lab use. Other than energy, the building uses 30% less than water than the university's baseline, furniture with reused material was chosen whenever possible and low-VOC emitting materials were used for paints and adhesives. Harvard also offers tips on its website for how labs can go green, with or without LEED.
Officials at Harvard say that they are going with the LEED program particularly because of the documented practices. Keeping track of what worked, documenting best practices and using this information as a benchmark level for future projects has kept the university from reinventing the wheel on each new green building. :Harvard's 20th LEED Cert
