This project, near Annapolis, Maryland, started with an ordinary 1980s brick rambler
overlooking the Chesapeake Bay. In renovating the home, the clients had two goals: to
create views of the Bay from as many rooms as possible and to build the most “green” house
the budget would bear. Dramatic views from almost every room were created through
numerous windows and 2-story spaces through which upper loft rooms can view the Bay.
Sustainability goals were met by using passive as well as active design strategies.
Passive design began with designing the new structure to sit atop the foundations of the old,
since no new disturbance was permitted on the site due to environmental restrictions. The
old building was deconstructed and the materials donated to a non-prot organization.
Other passive strategies included designing operable skylights and windows to draw fresh air
through the building at all levels, deep overhangs which block most of the summer sun and
none of the winter sun, rainwater harvesting for irrigation and other site uses, a storm water
inltration system, draught-tolerant native landscaping, and a living shoreline for breeding of
aquatic life.
Active strategies included geothermal HVAC and domestic hot water with desuperheating,
hydronic radiant oor heating, a photovoltaic solar power plant, high-performance building
envelope (R-55 roof with a white membrane, R-36 rain screen walls and triple coated low-e
glazing), fresh air intake tempered by an energy recovery ventilator, high eciency plumbing
xtures, PEX central distribution system and tankless water heating, Energy Star appliances
and lighting and the use of sustainable materials such as regional cypress cladding, FSC
certied engineered wood ooring, composite countertops, heat-treated pine decking and
zero or low-VOC nishes inside and out.
The house earned LEED Gold certication.
