Welcome to LEAFHouse

LEAFHouse, was awarded Second Place and the People’s Choice Award at the 2007 Solar Decathlon. Shortly thereafter, AIA Potomac Valley acquired LEAFHouse, which has served as our chapter house ever since. LEAFHouse is an inspiring building, and now you may tour it any time courtesy of our Matterport scan (below). Be sure to check out the “Mattertags” within the scan, which contain details about LEAFHouse’s innovative, sustainable technologies.

LEAFHouse plays a critical role in AIAPV’s and PVAF’s outreach efforts. Several years ago, the Potomac Valley Architecture Foundation (PVAF) invited the UMD Chapter of the American Ecological Engineering Society to utilize LEAFHouse for a variety of activities. Beginning with occasional potlucks, this has blossomed to include several sustainability-focused organizations, all members of the Sustainability Cooperative (SCoop) at UMD. The following video is a version of one that will be featured on the SCoop website in order to raise awareness about LEAFHouse and the concept of a sustainability park (conceptualized by AIAPV and PVAF), as well as to demonstrate the projects that take place at LEAFHouse and how they benefit the students, the Architecture Foundation, and the university. View the video on YouTube



Why is LEAFHouse special?

The Potomac Valley Architecture Foundation purchased the LEAFHouse (Leading Everyone to an Abundant Future) from the University of Maryland School of Architecture, Planning and Preservation. It was designed and built entirely by University of Maryland students and faculty advisors for the 2007 Department of Energy Solar Decathlon. It won second place in this prestigious international competition!

On Saturday, September 12th, 2009, the chapter dedicated the new chapter house with a ribbon-cutting ceremony.The ribbon was cut by (l to r) H. Michael Hill, AIA, President-Elect; Carl Elefante, FAIA, 2009 President; Chris Morrison, AIA, 2008 President; Lloyd Unsell, Jr., Hon. AIA, Retiring Exec. Director; Melanie Hennigan, AIA, 2006-2007 President; Michael Poness, AIA, 2005 President; and James Louviere, AIA, 2001 President.

What's it got to do with local architects?

The architects of our Chapter were so impressed with LEAFHouse that we bought it from the University to use as our office and as a public demonstration of an energy efficient building in action. We think we are the only AIA Chapter in the country with a net-zero chapter house! It also gives us the opportunity to interact with students at events like our annual Mentor Dinners with seniors in the School of Architecture.

Where is LEAFHouse?

We are at the north entrance to the University campus off Paint Branch Road. Getting to our street, Metzerott Road, is a little tricky, so click here for detailed directions.
