Property Spotlight – Home Built in 1912 Gets LEED Platinum Rating

leed

When architect Isabelle Duvivier of Duvivier Architects bought a dilapidated 100-year-old home in the neighborhood of her dreams, she kept the 950-square-foot floor plan but gave it a modern, environmentally friendly update that won a LEED platinum rating as well as the U.S. Green Building Council’s 2012 Outstanding Home Award. Rather than demolish the 1912 house, Duvivier remodeled. “I wanted to preserve as much of the original house as I could,” she said. A new second-story master bedroom is set back from the street to respect the scale of the Venice, Calif., neighborhood. Duvivier planted a vegetable garden in the front yard, as well as fruit trees and grapes along the alley.

“I’m a green architect through and through,” she said. “I wanted to go for high LEED (Leadership in Energy and Environmental Design) points, but my main goal was to demonstrate that a big component of green building is not building from scratch, but with what is there.”

Duvivier’s goal was “to reduce the footprint/impact of our house on the planet through water, energy and material efficiency.” To improve energy performance, the house has carefully placed windows, solar tubes and skylights. High-efficiency appliances and 95 percent LED lighting result in a home that is 53 percent more efficient than California standards. A 4-kilowatt solar array produces more electricity than the house uses 10 months out of the year.

San Diego’s LEED Platinum Dome Home

San Diego/Point Loma has a new LEED certified platinum home.  This home is a “dome-home” and the owner reports that his motivation for creating this home:

“One, was to do the very best I could to live with lowered demands on critical environmental systems. To me that meant living in a home that uses less energy and resources, creates less pollution and trash, and especially in Southern California, uses less water. My environmental activism began in 1981 when I started leading wilderness backpacks and hikes for the San Diego chapter of the Sierra Club. My green-building experience began in 2001 with my involvement in the construction of the Friends Center—a straw-bale office building for four non-profits that incorporated light-gauge steel (some “curved”) and radiant-floor heating.

How would this home be valued with all its green features?  Contact the appraisers at http://www.scappraisals.com ; they specialize in green properties.

 The second reason was to create a model for building professionals. Architects and contractors are invited to come and learn about the “green” systems, materials and techniques I’ve discovered over the last ten years of research. This is the volunteer part of this effort—helping them incorporate this philosophy of construction into their building practices.

The third reason for building this home is to use it as a model home for those of like mind who would like to reduce the destructive nature of their  environmental foot-print while living in the comfortable, healthy and inspiring space of an open, two-story urban dome. This is a four bedroom (or three bedrooms and an office) two bath home with a total area of 2,235 sq ft. This 42 foot diameter dome can be built on any lot with a width of 50 ft or more. This is a new kind of dome structure—never before done to my knowledge. Unlike the old geodesic dome, this home uses “curved” light-gauge steel studded walls to form the dome. There’s no dimensional lumber used and so no forest ecosystem destruction”.

The home owner reports that this feature is his favorite feature of the home is the radiant-floor space heating using solar heated water.  The system circulates hot water below the floor and the heat radiates upward and floats up to the top of the dome where there is a vent to the exterior.

The owner reported that his last utility bill the natural gas was 97 cents, his water bill was $6 and his electrical bill was a -$81 credit to him from the utility company.
