Hilton Garden Inn – West End
Washington, DC, USA
5,820 sf. Greenroof

Project Description & Details

Pursuing LEED Silver, the four-star 167,888 square foot Hilton Garden Inn West End hotel is an upscale mid-priced 238-room hotel situated within walking distance of Washington, D.C.’s most iconic attractions and corporations. Upon opening in May 2014, the Hilton Garden Inn began participating in the LightStay program, a Hilton Worldwide initiative to save energy by continuous measurement and reduction of electric, gas and water consumption. Contributing to the LEED accreditation, this property designed by Shalom Baranes Associates includes condensate recovery, ventilation recovery, low VOC finishes and seven separate vegetative roofs over three different roof levels.

Prospect Waterproofing installed the second level courtyard greenroof system by American Hydrotech with over thirty different varieties of perennials and deciduous shrubs in engineered growing media ranging in depths of 8″ to 16″. Triangular pyramidal skylights lend a modern feel to this outdoor space, while a perimeter green screen with trellising vines add additional urban greenification. Vegetation at the pool deck and penthouse roof levels consists of deciduous perennials intermixed with sedum and other succulents. Tall grasses installed near the building rising wall adjacent to the pool area offer contrasting vegetation heights. Below surface drip irrigation was installed and in lieu of standard irrigation timers, soil moisture sensors mitigate any unnecessary watering. Craning in a difficult and high-traffic area of DC made logistical coordination essential. Construction required coordination with multiple trades including masons, electricians, steelworkers and plumbers.
