But instead of draining this water, called condensate, Microsoft reuses it to irrigate the campus’s landscaping and help cool the building. The tech giant uses similar systems in its offices in Twycross, U.K., and Hyderabad, India. “We are also considering its inclusion in other Microsoft buildings depending on HVAC design, regional climates and other factors,” said Katie Ross, a senior sustainability program manager at Microsoft, in an email.
