What is Green Contruction and Remodeling?
New construction and remodeling the “green” way means using methods and choosing materials that have a smaller impact on the environment. Green homes use more materials from natural and recycled sources and they use fewer resources such as energy and water by being more efficient. A green home is healthier for its inhabitants and less wasteful and polluting for the land, water, and air around it. By 2010, some 50% of all builders in the U.S. plan to produce at least some homes with green methods and materials.
Green Building Materials
As with new construction, use recycled materials and those with low VOCs. Check to see if demolition waste such as concrete, carpet, plastic, pipe, drywall, metals, brick, paper, cardboard, and yard clippings can be recycled in your area. Build a deck from the lumber of a demolition building, old railroad trestles, or harvested trees from an urban area. Use a deck surface that does not need to be stained, such as plastic lumber. Plastic lumber cannot bear heavy loads as well as wood and may need steel reinforcement, but it will degrade slower and last longer without the use of a stain.
Materials
Consider the following materials in all new construction and remodeling:
Use Material
Lumber FSC (Forest Stewardship Council) certified
Flooring Bamboo or cork
Flooring and counters Refurbished tiles or stone
Decking and fences Plastic lumber
Roofing Recycled shingles
Paint Recycled paint
Carpet and padding Recycled and low VOC
Appliances Energy Star certified
Economics of Green Building
Implementing green products and practices reduces operating costs, and have a clear economic advantage after calculating the overall cost of construction, use of tax rebates and other incentives, installation, operation, maintenance, repair, replacement and disposal over the life of a residence.
Sustainable materials and systems are becoming more affordable because demand is increasing by builders and occupants. The U.S. Green Building Council (USGBC) indicates that if the up-front costs are significantly higher, then it is most likely due to inexperienced builders, architects, and other industry professionals who are uninformed about how to cost-effectively design and construct green homes.
According to the U.S. Environmental Protection Agency and the Department of Energy, the average home spends about $1900 annually on energy bills. Half of this energy use is due to heating and cooling.
ü A well-insulated home with energy-efficient equipment that is properly sized and installed and maintained correctly could further reduce heating and cooling costs 20-40% annually.
ü People who live in green homes use 50% less water than standard homes.
ü Home insurance in the future will most likely be less for green homes as compared to standard housing. A precedent has been set by the Fireman’s Fund Insurance Company which already offers a 5% discount for LEED certified commercial buildings.
ü The value of green homes is greater than comparable homes on the market. In Rocklin, CA, a 144-home development, which has every home LEED-certified, outsold competitors 2 to 1.
ü With improved health, there are fewer visits to the doctor.
ü More durable materials are used in green building, thus requiring fewer repairs.
