The World's Most Energy Efficient Residence Hall
Located two blocks from the White House on the Foggy Bottom campus, Thurston Hall is George Washington University’s largest freshman residence hall and is critical to the first-year experience for many students. The 100-year-old building has seen many uses since in its lifetime but had previously had no comprehensive renovations. CMTA served as the MEP engineer for this 200,000 square foot complete interior overhaul.
The building features a Dedicated Outdoor Air System (DOAS) with heat recovery, high-efficiency magnetic bearing chillers, rainwater collection, and Building Integrated Photovoltaics (BIPV). A radiant heating system will help make the central atrium courtyard useable ten months of the year, while the overhead BIPV canopy is being carefully designed to balance daylight access with solar heat gain. The lower level dining service incorporates energy-saving strategies, including water source refrigeration, induction cooking, and reduced exhaust airflow. An active circadian lighting system will be used for interior spaces that have no viable daylighting options.
The project scope also includes pipe fan coils on the upper floors and heat pumps on the lower non-residence levels, a dedicated outdoor air delivery system with energy wheel, magnetic bearing chillers, high-efficiency condensing boilers and hot water heaters, rainwater collection, and shower drain heat recovery for domestic hot water pre-heating. These high performance systems will ensure occupants of the building have a healthy environment for living.
