As part of a $7.9 million contract with Baltimore-based energy company Constellation, more than 13,000 light fixtures at the World Trade Center in New York will be switched to LED sources in an effort to reduce the structure’s carbon footprint by 4,700 metric tons annually—the equivalent of removing 1,000 passenger vehicles from the road. According to a recent release, the Port Authority of New York and New Jersey could save more than $715,000 in the first year of the decade-long contract, with continued savings over time. Constellation has already begun the upgrade work, which is expected to be completed by the end of 2019. The retrofit will also switch the existing uplighting at the Oculus, the transportation hub designed by Santiago Calatrava, FAIA, to color-changing spotlights. [Constellation]

Vancouver, British Columbia–based A&K Robotics has partnered with the University of British Columbia (UBC) in the development of autonomous floor-cleaning robots, which can now been seen scrubbing throughout university’s campus buildings. During a pilot program in May, the A&K team worked with university staff to train the robots and test their efficacy. Since then, A&K—whose founders are UBC alums—has secured a contract with Vancouver International Airport, among other clients. [UBC]
