What are Green Buildings?

There are many definitions. Some define green buildings as indigenous architecture that utilizes local materials and design options as well as utilizes passive solar. Adobe Homesin New Mexico are often a good example of this concept.

Others define green buildings in more modern terms. Over the past 20 years, the term "green buildings" has evolved from many experiments and programs developed around the country, such as Austin's green building program.

The U.S Green Building Council has developed LEED standards for commercial buildings and has a pilot program to develop LEED standards for residential buildings. Buildings become LEED certified by including a specified green building standards for construction.




In general, many of the green building programs often include some of these general principles:

•Site Selection, Design and Preparation: Design sites to have the minimum impact upon wildlife, trees, and other natural features.
•Educate contractors on minimizing environmental impact on construction sites. Recycle remainder building materials and minimize waste as well.
•Design buildings to efficiently use natural light, building orientation to sun, and other site features.
•Select low-impact building materials whenever possible—renewable materials (ex. Bamboo) or recycled materials.
•Select building materials with low volatile organic compounds and off-gassing for healthy indoor air quality.
•Energy-efficient appliances and HVAC systems.
•Solar energy whenever possible.
•Xeriscaping or other native plants for landscaping to eliminate the use of pesticides, herbicides, and fertilizers. Minimize the use of water for landscaping. Use organic gardening practices.
•Select low-maintenance building materials whenever possible to minimize the future use of building materials and lower long-term costs.
•Promote less-toxic house cleaning practices to minimize indoor air pollutants and contaminants in water runoff.

How Healthy-Home Gardening Can Save Water and Reduce Pollution

Landscaping choices for your garden can contribute not only to a healthier lifestyle but also can help save water and reduce water pollution. Water conservation has become a significant issue for many communities, particularly for many U.S. states in the west and southwest.

Texas is also now facing water shortages and future potential water shortages as the population growth outpaces the local water supply. Texas depends upon a system of lakes and rivers to collect surface water from runoff. This runoff can become polluted with pesticides, fertilizers, herbicides, and sediment. It is important for Texas as well as other communities to conserve water and preserve water quality.

The Texas Extension Service--Tarrant County and the North Central Texas Council of Governments, along with other collaborators, created the Texas SmartScape® program, http://www.txsmartscape.com/ ,to teach homeowners and businesses how to select plants and maintain landscaping to reduce water usage and reduce the use of pesticides, herbicides, and fertilizers. This program is based upon principles included in Earthkind, xeriscaping, waterwise, and yard-smart programs that many other communities around the country now support.

Some of the basic ideas are:

1. Select native or locally-adapted plants. These plants require less water, fertilizers, and pesticides.
2. Whenever possible, avoid chemical pesticides, herbicides, and fertilizers and opt for natural alternatives.
3. Water the garden at night or early in the morning when there will be less evaporation from heat.
4. Use drip irrigation when possible.
5. Mulch plants to preserve soil moisture and add beneficial elements as it decomposes.
6. Avoid watering immediately after applying any fertilizer, even organic slow-release fertilizer.

The website even helps homeowners or businesses design their landscaping.
