Green home design is the wave of the future. Consumers are becoming more aware of the negative effect daily living has on the environment, resulting in increased acceptance of the need for change. Over the last 30 years, efforts to develop technology and build more environmentally friendly homes are paying off. The increase in demand for green home design from 2005 to 2010 is expected to increase from 2 to 10 percent.
There are distinct characteristics required to classify a home as "green". A green home design typically incorporates conservation of energy, water and natural resources, use of renewable energy, waste reduction and a healthier environment. Building materials are made from natural, toxin-free products and recycled components. Paints and sealants have low VOC (volatile organic compound) content, and wood and insulation products are often made from rapidly renewable sources, such as bamboo, soybeans and cotton. Windows and doors have a high Energy Star rating and electric appliances and HVAC (heating, ventilation and air conditioning) systems must be energy efficient. The green home design incorporates the use of windows and skylights to take advantage of natural light, with trees and other shading devices used to limit heat from summer sun. Air quality is freshened and cleaned through use of both natural and mechanical filtering and venting. Solar energy is a popular renewable energy source used in green home designs. Green homes are often built on previously used parking lots or building sites and wetlands are avoided; existing trees are retained whenever possible.
Green home design has benefits that outweigh the cost of construction. The design and the natural materials lead to reduced internal pollution, and reduction or elimination of mold, mildew, carcinogens, and respiratory pollutants. This creates a healthier environment, reducing risks of respiratory, heart and allergy problems and cancer. The ecological-friendly products and resource conservation create fewer green house effects and pollutants, reducing the negative impact on the environment. The advantages of green home design include financial as well as health and environmental benefits since energy and water use is nearly cut in half. With knowledgeable contractors the construction costs are said to be about the same or less than conventional home construction. Additionally, initiatives by private agencies and government to build low cost green homes will further benefit construction costs at all income levels.
As the technology improves, contractors gain experience, and probably most importantly, consumers gain increased awareness, we should expect to see an increased growth in the demand for green home design.
