What is Green? | |

The question really is "why do we have this thing called green" The answer lies in the fact that there are more than 55 million single-family residences in the United States, and they use approximately 36 percent of the energy sold in this country. The average household consumes the equivalent of 1,092 gallons-26 barrels-of oil each year for its heating, cooling and other energy needs. Extensive use of fossil fuels, which make up 75 percent of the U.S.'s energy production portfolio, has degraded our environment, human health, and land resources. On a large scale, focus on energy efficiency can reduce emissions that contribute to smog, acid rain, polluted waterways and global warming. Energy-efficient structures reduce emissions that cause global climate change and pollution. (Statistics from Tate Walker, Energy Center of Wisconsin) The term "green home" describes a home that uses less energy, water, and natural resources; creates less waste; and is healthier for the people who live inside. In addition, the green homeowner will experience such benefits as lower energy and water bills; reduced exposure to mold, mildew, and other indoor toxins, as well as reduced amount of greenhouse gas emissions. On average, people spend 90 percent of their time indoors. Since contaminants can be two to five times worse inside than outside, indoor air quality should be of high importance. Homes can be more comfortable and less prone to bacteria and mold growth if insulation, air and moisture barriers are installed properly, and heating and cooling systems are properly sized and maintained. Natural ventilation and light have a pronounced effect on our physical and mental well being. A lack of these amenities can contribute to seasonal affective disorder, allergies, asthma, and some types of cancer. Strategies like passive solar design can help reconnect people to the outdoors and their own biorhythms, making energy efficiency just an added benefit. |
