Design of an Educational Center for Kingman and Heritage Islands in Washington, D.C. begins with the appreciation of place. Washington is located at a confluence of the Anacostia and the Potomac rivers. It is part of the largest estuary on the continent, a watershed that flows into the Atlantic Ocean. Conversion of Riparian zones for other land uses has created ecological problems in waterways and the Chesapeake Bay.
Kingman exemplifies human settlement as a part of nature. The site allows cycles of nature and man to work together. This makes people happier and healthier, and ecosystems sustained and regenerated.
This project demonstrates how to “touch the earth lightly” by harnessing natural resources and mimicking natural flows. It makes use of passive strategies for heating/cooling/ventilating and regenerating wetlands. These “constructed wetlands” will work with a “Living Machine” to demonstrate habitat restoration and of wastewater treatment. The building becomes part of the landscape functionally and physically.
The center is laid out in four “landforms” that surround natural plazas. Trails lead from outdoor classrooms to the living machine, the constructed wetlands, the lakeshore, the observation tower, the river and the 9/11 memorial.
Green roofs, pervious paving, and integrated landscaping manage stormwater on site and assist in groundwater recharge. Rainwater is harvested for use in the facility. Greywater is recycled while wastewater flows into the Living Machine and constructed wetlands for treatment. When water reaches Kingman Lake, it will be clean enough to drink.
Passive strategies such as thermal masses help keep the building comfortable in all seasons. Backup systems use a geothermal loop. The sun’s energy is harnessed with PV’s for electricity and panels for hot water. Natural ventilation completes cycle and avoids putting a strain on the environment. Daylighting strategies keep the interiors well-lit while affording views and ventilation.
