Here are the categories:
Innovation and design (9 possible points)
Includes integrating green strategies and planning for durability.
Location and linkages (10 possible points)
Includes environmentally sensitive site selection, development near existing communities, development within walking distance of transit and basic services, access to open space.
Sustainable site (21 possible points)
Includes site “stewardship,” landscaping with drought-tolerant plants, management of stormwater runoff, non-toxic pest control and use of high-density development.
Water efficiency (15 possible points)
Includes reuse of rainwater and indoor water (gray water), reduction of water use in sinks, toilets and showers, and use of high-efficiency irrigation system.
Energy and atmosphere (38 possible points)
Includes use of basic or enhanced insulation, minimizing air leakage, use of energy-efficient windows, proper insulation around heating and cooling systems, use of programmable thermostat and high-efficieny heating system and cooling systems, use of efficient hot-water heating system, use of emergy-efficient lighting fixtures, appliances, use of renewable energy systems (1 point for every 5 percent of electrical load, up to a maximum of 10 points).
Materials and resources (14 possible points)
Includes reducing waste from building framing, use of local or “certified tropical” wood and environementally preferable material such as bamboo and linoleum, recycling and resue of materials, reducing waste from construction process.
Indoor environmental quality (20 possible points)
Includes proper sealing to minimize leakage from space and water heating systems, proper ventilation of fireplace and woodstove, moisture control system, proper ventilation to outdoor air, exhaust fans for bathroom and kitchen, filtration, sealing off garage from home, and contamination control.
Awareness and education (3 possible points)
Includes training of occupant, owner’s manual and ongoing management.

GreenBuilding070508[i-1].body = "The National Association of Home Builders has drafted a standard that it intends to submit to the American National Standards Institute, or ANSI.
Projects will be rated on a point system to qualify for bronze, silver or gold status.
Here are the areas where builders will be rated, along with the minimum points needed to qualify for bronze status:
Building lot (minimum 8 points)
Includes minimal impact, conservation and preservation of natural resources, minimal slope disturbance, maximum use of solar resources, management of storm water, low-water and –energy landscaping.
Resource efficiency (minimum 44 points)
Includes reduction of construction materials and waste, improved durability, use of recycled, salvaged and renewable materials, recycling of construction waste.
Energy efficiency (minimum 37 points)
Includes appropriate heating and cooling equipment, proper insulation, energy-efficient windows, energy-efficient water heater, energy-efficient lighting, potential use of solar power and other renewable energy sources.
Water efficiency (minimum 6 points)
Includes reduction of indoor and outdoor water use in sinks, appliances toilets and irrgiation systems.
Indoor environmental quality (minimum 32 points)
Includes proper ventilation of heating, hot water supply, stove, bathrooms and fireplaces; proper sealing between garage and home, use of low-toxicity adhesives and materials, use of proper vapor barriers in walls and under floors,
Operation and maintenance (minimum 7 points)
Includes providing an owner’s manual, training in building controls
Global impact (minimum 3 points)
Includes use of low-toxicity paint and sealants
Additional points (minimum 100 points)
To qualify as a green home under the NAHB proposed standard builders also would have to accumulate an additional 100 points in any category.
