Welcome to LEAFHouse



Visit us on Maryland Day, and learn more about our chapter's own solar-powered home, LEAFHouse, and its unique systems, such as the Liquid Dessicant Wall dehumidifier and poly-ash replacement siding. Experience the building's open and thoughtful architecture that mimics the solar concept of a leaf.

Learn about plans for future enhancements, as well as how LEAFHouse and the Potomac Valley Architecture Foundation facilitate collaborations with student groups and researchers from the University of Maryland!

UMD's 2017 Solar Decathlon entry, reACT, is also on display next to LEAFHouse. It's not open yet for tours, but you can see a presentation on reACT's design and features and talk with members of its team about how LEAFHouse helped inform the design of reACT.

LEAFHouse is the University of Maryland's 2007 award-winning Solar Decathlon entry, now owned by the Potomac Valley Architecture Foundation and serving as the chapter house for AIA Potomac Valley. Join us for a day of hands-on demonstrations showing ways to apply the latest thoughts on sustainability to our homes and landscapes, in conjunction with the University of Maryland's Maryland Day 2018.

LEAFHouse demonstrations on Maryland Day will include:

  • Solar PV panels powering a mini-fountain
  • Hot chocolate from a solar cooker
  • Building materials that save energy, capture carbon and help manage water runoff
  • A blower door and thermal camera, and how they reveal energy leaks in buildings
  • Tower gardens that grow food in small spaces
  • Vertical wall and native landscape plantings
  • Live music!

Why is LEAFHouse special?

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! 

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.
