Project Details

Project Site Sustainability
  • All mature plants were saved
  • Drought tolerant landscaping (work in progress)
  • Owner to remove the existing front lawn — the goal is no turf grass
  • Original concrete block patio, brick from fireplace and outdoor tiles saved and made into an outdoor bench along new back patio
  • Old, unsafe Acacia tree on neighbor’s property removed and used as mulch to amend soil and moderate moisture evaporation

Water Efficiency

  • Water efficient whole house filtration and water softening system does not require electricity or use of salts
  • Roof runoff collected in drywell allows water to slowly percolate back into groundwater
  • Two dual flush toilets
  • Water efficient bathroom and kitchen fixtures
  • Tankless (on-demand) water heater

Energy & Atmosphere

  • New passive solar features include increased amount of south window area to allow natural sunlight; new overhangs and trellis reduce heat gain on south side of home
  • Owner found “radiant barrier” paint additive that helps reduce heat gain when applied to underside of roof
  • Owner found paint product with ceramic particles that increases the insulation and thermal mass capabilities of walls
  • Gas fired “on-demand” water heater — EF of 82
  • Solar hot water heater
  • Energy efficient, Low-E2 windows with fiberglass clad exterior
  • Icynene insulation in all exterior walls to limit infiltration losses
  • Cellulose insulation in ceiling
  • Whole house fan helps cooling interior
  • New walls constructed with 2 by 6 framing to increase insulation capacity
  • Skylight provides natural lighting
  • All new exterior doors are being installed to reduce air infiltration
  • Compact fluorescent lights and new LED technology installed in high use-areas of house
  • Standard outdoor lighting will be replaced with fluorescent and LED super low wattage lights
  • Infrastructure for photovoltaic panels provided for future installation.

Materials & Resources

  • Comprehensive construction demolition plan implemented with goal of diverting 95 percent of project’s waste; actual diversion 85 percent (equal to 93.6 tons of waste diverted)
  • Product reuse: five windows given to neighbors; doors, furnace, and appliances donated to Salvation Army; eight doors, toilet, pedestal sink and wall heater donated to Habitat for Humanity; four windows, shutters, and fireplace mantle bought by antique dealer
  • Existing oak flooring sold for reuse on Craig’s list to local family
  • Owner reused old kitchen cabinets, bookshelves, and closet shelving
  • Reusable materials used for construction fences
  • Locally harvested Acacia tree milled in San Luis Obispo used for all cabinet trim, shelves and a window bench
  • Owner used salvaged bathroom sinks, faucet hardware and vanity light fixtures from Orange County construction project
  • Sustainable building materials including bamboo flooring and wheatboard cabinets, and cellulose insulation (recycled newspaper with a class-1 fire rating)
  • Natural linoleum in bathroom and utility room
  • 20 percent of framing lumber FSC certified
  • 50 percent fly-ash used in cement mixture
  • Exterior of house finished with color integrated stucco and fiber cement board reducing long-term maintenance
  • Roof has an expected life of 50 years

Indoor Environmental Quality

  • Wheatboard and formaldehyde-free melamine shelving and cabinet materials
  • American Pride zero-VOC paints and coatings from Livingreen were used on the interior of the home. Dunn Edwards Eco-Shield paint was used for some interior finishes.
  • Nontoxic sealants, adhesives and oils used
  • Operable window promote circulation of fresh air.
  • No carpet used in the home
  • Water filtration system provides clean fresh water for the residents

Innovations & Special Features

  • Owner conducted preremodel analysis of home’s energy usage and monitored energy demand after remodel complete to determine effectiveness of energy efficiency improvements
  • High efficiency residential LED lights installed in kitchen, front patio, hallway and closets meet Title 24 standards. LED lights are 3 to 4 times more efficient than halogen and incandescent lights and last for 15-20 years.
