Some interesting facts… -Residential properties are responsible for 21% of the nation’s carbon dioxide emissions. -Residential properties built to U.S. Green Building Council standards usually save people 30-50% on their energy bills!

What makes a home green? Energy efficiency -CFLs (compact flourescent lightbulbs) -Ducts in properly insulated areas -Solar screens, window film, and Low-E glass

Indoor Air Quality -Sustainable flooring: concrete, wood, tile

Water safety and efficiency -Low flow toilets and shower faucets -Rainwater harvesting -Xeriscaping

Renewable/recycled and durable materials -Recycled, non-toxic insulation materials -Cement products with new technologies such as Flex-Crete which uses non-toxic fly ash (a byproduct of coal plants)

Proximity to community resources -Access to public transportation, grocery, etc.

Using nature to our advantage -Placing vertical opening windows to take advantage of SE tradewinds -Special roof features to shade high-sun areas of the home

Where do I start? A good place to start is your local energy program websites. You will be able to read about many ways to save with rebates, loans, and also just the simple things you can do around the home. Check it out – you will be surprised by just how many resources are there. You can also visit our ‘Green Links’ page for other going green resources.

Carbon Footprint - a measure of the amount of carbon dioxide emitted through the combustion of fossil fuels. A carbon footprint is often expressed as tons of carbon dioxide, or tons of carbon emitted, usually on an annual basis.

Certified Wood - Under the guidance of the Forest Stewardship Council (FSC), wood-based materials used in building construction that are supplied from sources that comply with sustainable forestry practices, protecting trees, wildlife habitat, streams and soil. Chlorofluorocarbons (CFC) – A group of volatile gases believed to deplete the ozone layer of the Earth’s stratosphere. These gases have been discontinued from use as refrigerants and as blowing agents used to make foam. Energy Efficient – Products and systems that use less energy to perform as well or better than standard products. While some have higher up-front costs, energy-efficient products cost less to operate over their lifetime. Energy Star® Rating – The label given by the EPA and the U.S. Department of Energy (DOE) to appliances and products that exceed federal energy efficiency standards. This label helps consumers identify products that will save energy and money. ENERGY STAR® -labeled appliances often exceed the efficiency levels of other new products. Formaldehyde – A gaseous chemical used to bind together and preserve building materials and household products – such as carpet. A potential carcinogen, its use should be avoided whenever possible. Fossil Fuels – Fuels such as coal, oil and natural gas extracted from beneath the Earth’s surface, often with significant environmental and political cost. These fuels are a finite resource and are non-renewable. Green (products or design) – While there are many definitions of “green” or “sustainable,” the one most commonly used looks at meeting the needs of the present without compromising the ability of future generations to meet their needs. A truly “green” product would be durable, repairable, energy efficient, made with recycled materials, and eventually recyclable. Also, the manufacture, use, disposal, and packaging would have minimal impact on the environment. Rainwater Harvesting – Through the use of appropriate roofing materials and gutter systems, rainwater can be harvested or collected then stored for future non-potable use such as showers, watering, etc.

Renewable Energy – Energy harvested from sources that are not depleted when used, typically causing very low environmental impact. Examples include solar energy, hydroelectric power and wind power.

Sustainable (products or design) – While there are many definitions of “green” or “sustainable,” the one most commonly used looks at meeting the needs of the present without compromising the ability of future generations to meet their needs. A truly “sustainable” product would be durable, repairable, energy efficient, made with recycled materials, and eventually recyclable. Also, the manufacture, use, disposal, and packaging would have minimal impact on the environment.

Volatile Organic Compound (VOC) – These substances are indoor air pollutants or chemical compounds that exist as vapor or gases at normal temperatures and are carbon-based molecules typically used as solvents in products such as household cleaners, paints, inks and dyes.
