Better Buildings Summit Showcase Tours: The Washington Hilton Hotel

Stay tuned for more highlights from this year’s Better Buildings Summit Showcase Tours.

Built in 1965, the Washington Hilton is a regular host to the White House Correspondents Dinner, the National Prayer Breakfast, and in recent years, the Better Buildings Summit! Hilton Worldwide, a flagship Better Buildings Challenge partner, hosted a behind-the-scenes tour for Summit attendees to showcase their sustainability efforts. The group was able to explore the roof, the central plant, the boiler and chiller rooms, a guestroom, and the kitchen, in addition to a Q&A with Hilton’s Malick Gueye. All steam is produced onsite, and all boiler and chiller equipment is monitored through the building automation system. The hotel also uses a food digester to discard food waste in the kitchen; the digester uses chemicals to turn food waste into a liquid, which is pushed down a drain to sewage. Hilton is planning to install occupancy-based plug controls in guestrooms via door locks/door sensors; the original wiring system of the hotel does not allow for central automation. The hotel has been collecting energy data in LightStay, Hilton’s internal sustainability monitoring tool, since 2010; they’ve achieved 16% energy savings over three years and received DOE’s SEP Certification in 2015.
