Building Green: One Woman’s Journey 7 May 10 Florissant Valley CTL Peggy Moody Ph.D Assoc Prof Psychology & District Sustainability Coordinator The Buffalo River National Park Yellville, AR Courthouse Caney, AR 10 miles from Yellville My topography Arkansas dreaming Land of rivers Buffalo River National Park Land of trails Ozark Trail system Land of caves Many people used these caves for shelter Mammoth Spring Caves Land of quiet reflection Tom & Tere overlooking the Buffalo and Ozark hills Land of family Tere and her pumpkins Mom’s visit What is building green? For me, Design that will be energy efficient; Kind to the earth placement on the land use of materials keeping my footprint as small as possible; Cradle to cradle from first dig to the possibility of deconstruction 200 years from now. Many green certifications EarthCraft Home rating (South Eastern states) Environments for living (GE) Healthy House standard (Am Lung Association) Energy Star (cut energy by 15%) NAHB (National Assoc of Home Builders) LEED (Leadership in Energy and Environmental Design) from USGBC Seven guidelines (NAHB) Energy efficiency Resource efficiency Water efficiency Lot development Green Building Guidelines (cont) • Site development • Indoor environmental quality • Homeowner education Beginning NO certification (for now) My sister Tere and husband Tom built their home by themselves Tere and Tom’s 20 x 24’ cabin Site location Where could we cut the fewest trees? Site location (cont) The view of my “hollers” South orientation to capture passive solar (FREE winter warming) Cut few trees to preserve FREE cooling in the hot and humid Arkansas summers Building Design FUNCTION Garage with a woodshop (16x20’) Fabric art studio (16x20’) Porch for shading intense summer sun from studio Spot for composting toilet outside my studio Studio double as guest cabin Building design (cont) AESTHETICS Lots of LIGHT and nature’s views A sense of SPACE— deck increased living space. My Design Flooring—piers, rather than foundation (less concrete, better air for cooling) Roofing—5 on 12 pitch trusses; scissor for in studio (creates more spacious ceiling), regular trusses for garage (storage in rafters) Porch—8’ L-shaped deck allows access to the woods all around, and to my view of the hollers (2); roof overhangs deck creating a 40x20 arial view Design (cont) Windows West (view) facing--5.0’ window + full glass door + 3.0 window over kitchenette sink South (passive solar) facing—2 5.0’ windows East (sunrise)—2 3.0 garage windows North (winter winds)—no windows Design (cont) Landscaping—natural, using native azaleas and wildflowers; paths in wood chips that are in abundance after ice storm of Feb 09 Indoors—front door on West wall, kitchenette; “cube” loft (with futon); open studio W S Outlets for cube Materials Driveway—30 tons of limestone chip stone (porous pavers as I can afford) Piers—12 sonotubes; 16 bags of cement (8” tubes in garage; 12” on studio); rebar; and rock from property Flooring—beam joists; plywood (without formaldehyde glue); and stone tile for catching passive solar Materials (cont) Studs—2x6” locally purchased wood for walls and trusses; wider depth allows for more insulation Insulation—corn-based foam insulation, (contractor installed) Drywall—standard, but investigated “green” drywall made from post-consumer materials— very new (expensive) option Materials (cont) Free (reusing) Wood stove—plenty of natural wood source from downed trees on property 2 fans—energy star (cooling and warming) Open kitchen cupboards (FSC); recycled sink from yard sale; propane stove; high energy-efficient chest frig Materials (cont) Composting toilet—no water, tank below deck for easy disposal of “dirt” 1500 gallon Cistern--collecting water off roof Metal roofing--cream-colored paint for deflecting sun’s heat Siding—Hardie Cement Board—long lasting & fire-resistant Plastic wood decking—gray-green color Solar panels—electric, off the grid—energy from the sun Energy-efficiency Heating Wood stove Passive solar from stone tile radiated into room Plenty of trees to block winter winds Cooling 2’ eaves for more shelter from hot sun 8’ porch on West side to shade setting sun Shade from many trees in west Fans and cross ventilation Energy-efficiency (cont) Electricity Solar panels Air-Tight building shell High R value for insulation Caulking (without fumes) Water Collecting water off roof into cistern Year-round spring on property; 700’elevation below studio; 2ndcistern above my home that gravity feeds to me (and to sister’s garden and orchard) Just finished Tile flooring Turn around in driveway My first tiny solar panel! Still to come… Solar array and battery system Garage floor Building kitchenette and cube You too can make your dreams come true!
