John Lewis Elementary School

Engenium Group provided plumbing engineering design and fire protection services for the renovation and modernization of John Lewis Elementary School (formerly West Elementary) in Washington, DC. Located in Ward 4, the modernization of the 90,000 SF school serves more than 350 students in Pre-kindergarten through Grade 5.

John Lewis Elementary is among the first Net Zero Energy-Ready and WELL Certified Schools in the District. The design and layout of the school combines a focus on indoor environmental quality variables and other components that promote health and well-being.

Net-Zero plumbing design elements include:

  • Energy efficient hot water system utilizes a water-cooled heat pump connected to a geothermal system
  • Condensate drainage water recovered from air handler units supplies the irrigation system
  • Hot water recirculation system optimized to reduce energy consumption
