能源利用: Photovoltaic panels were installed in easily-transportable trailers to provide solar-electric powered pumps. The PV systems were chosen not only because of the fiscal and environmental benefits of renewable energy, but because the systems could be portable. The solar-powered water-pumping trailers feature self-contained power and controls, which power the permanently installed well pumps as well as the mobile toilet and cabana lighting systems. There is also a 20-amp, 120-VAC duplex outlet inside each trailer for auxiliary power. Each trailer includes 16 75-watt Siemens PV modules, for a total of 1200 watts per trailer.

The bathhouse is totally powered by electricity generated on-site using photovoltaics. Because the system is not grid-tied, no metering was installed and end use numbers are not available. While the actual usage is unknown, 100% of the energy used is produced on site with photovoltaics.

 节水方案: The lightweight changing rooms, built with stainless-steel tubes and wrapped in synthetic canvas, are easy to set up and dismantle, allowing easy removal from the beach during pre-storm evacuations.

The modular, movable boardwalks are constructed of lumber salvaged from the demolition of the old Toms Cove bathhouse. The surface is wheelchair-accessible, stable to walk on, and easy to remove before a storm.

Each toilet's black PVC chimney absorbs solar energy, creating a natural convection current. Heated, stale air rises out of the chimney, while fresh air is drawn into the wall vent. These toilet structures are modified to facilitate rapid removal from the beach during pre-storm evacuations.

A mobile, solar-powered utility trailer houses all equipment required to pump fresh water to the solar shower tower, which provides a fresh, cold-water rinse. The shower is modified with quick-disconnect fittings to allow repeated, rapid installation and removal.

Each 115-VAC, 12-horsepower pumping station provides a minimum of 1,920 gallons of water per day to operate four six-foot freestanding shower columns. The water source is a 100-foot deep well with an average static water level of five feet below ground. The pumps deliver a minimum of eight gallons per minute at 20 pounds per square inch at the showerheads. The pumps maintain water pressure with an electro-mechanical pressure switch, a two-gallon expansion tank, and an on-demand controller.

设计创新: Assateague is an island on the move. The ocean, shifting sand, and seasonal storms constantly transform the landscape. Natural forces have damaged beach facilities over the years. At Toms Cove, the National Park Service is responding with mobile bathhouse units. Easy to remove and reposition after a storm, each unit includes lightweight changing rooms, passive-solar vault toilets, and a solar-powered shower.
