ACESD is a state-of-the-art aquatic research facility of EPA's Center for Environmental Measurement and Modeling (CEMM) under the Office of Research and Development (ORD).

Sustainable Features

  • The facility is undertaking a multi-phase infrastructure replacement project (IRP) to upgrade mechanical, electrical and laboratory equipment with more efficient systems. As part of the IRP, the laboratory plans to install a ground source heat pump that will use geothermal energy to provide heating and cooling to support the facility and provide winter process cooling for the seawater system.
  • EPA developed a Sustainable Site Master Plan to provide a clear path for its phased laboratory modernization projects, which included reducing lawn mowing and replacing vegetation with native, non-invasive plant species that encourage healthy foliage growth.
  • The facility has a green roof and 1,200-gallon cistern to capture excess stormwater runoff through roof drains, and AED reuses the water for irrigation during dry periods.
  • A 5 kilowatt (kW) photovoltaic (PV) array helps offset some of the laboratory’s energy use. In FY 2019, the renewable energy system generated 4,654 kWh.
