Sustainable flooring is produced from sustainable materials (and by a sustainable process) that reduces demands on ecosystems during its life-cycle.[ according to whom? ] This includes harvest, production, use and disposal. It is thought that sustainable flooring creates safer and healthier buildings and guarantees a future for traditional producers of renewable resources that many communities depend on.[ according to whom? ] Several initiatives have led the charge to bring awareness of sustainable flooring as well as healthy buildings (air quality). [1] [2] [3] Below are examples of available, though sometimes less well-known, eco-friendly flooring options. [4] [5] [6] [7] The Asthma and Allergy Foundation of America recommends those with allergies to dust or other particulates choose flooring with smooth surfaces – such as hardwood, vinyl, linoleum tile or slate.
In the U.S., the Building for Energy and Environmental Sustainability (BEES) program of the National Institute of Standards and Technology (NIST) [8] provides a one-stop source of life cycle assessment-based information about flooring options. Life cycle comparisons of flooring alternatives by research groups around the world consistently show bio-based flooring products to have lower environmental impacts than other types of flooring. The life cycle environmental impacts associated with producing and using flooring alternatives such as cork, linoleum, and solid wood are clearly lower than other alternatives. Wool carpeting and composite marble exhibit the greatest impacts, and impacts linked to typical carpeting used in residential structures are higher than those shown in the BEES system due to the use of a pad under the carpet layer. [9]
The development of life cycle assessment methodology in the early 1990s has shown the environmental advantages of wood and wood-based products. [10]
Wood is a unique and renewable material. Trees absorb carbon during their growing cycle, and this carbon remains stored in products like wood flooring during its service life, thus keeping it out of the atmosphere. At the end of its service life, wood can be reused (in which case the carbon continues to be stored in the wood) or used for fuel. [11]
A life cycle assessment of flooring materials made of solid wood, linoleum and vinyl found the wood flooring had lower energy use and carbon dioxide emissions. It also performed better in environmental impact categories such as resource use, environmental toxin emissions, air pollution emissions and waste generation. [12]
When reclaimed wood is used for wood flooring, [13] it is taken for reuse from many different sources, including old warehouses, boxcars, coal mines, gymnasiums, homes, wine barrels, historic barns, and more. Wood can also be recovered from rivers in the form of fallen trees along with logs that were once sent downstream by lumber mills. Parquet flooring in herringbone, double herringbone, or chevron style can be reclaimed from buildings typically undergoing demolition or renovation. Typically the flooring will have been in its original home for over 100 years. Occasionally very rare woods, including old growth teak, mahogany, oak and more exotic timbers such as panga, wenge, bubinga are utilized. Some of these woods, eg Rhodesian Teak are simply not in production any more, due to forestry or importation limits. The process of reclamation includes salvage, transport, cleaning of old bitumen residue, refitting and sanding with finishing by lacquering or oiling.
Using reclaimed wood can earn credits towards achieving LEED project certification. Because reclaimed wood is considered recycled content, it meets the Materials & Resources criteria for LEED certification and because some reclaimed lumber products are FSC certified, they can qualify for LEED credits under the "certified wood" category. [14] Besides qualifying for LEED points, reclaimed wood is drawing an increasing number of home and business owners, architects, and contractors to choosing reclaimed wood flooring for a few significant reasons: [15]
Bamboo flooring is made from a fast-growing renewable "timber" (bamboo is actually a grass). It is natural anti-bacterial, water-resistant and extremely durable. DIY installation is easy, as bamboo flooring is available with tongue-and-groove technology familiar in hardwood/laminate alternatives. Bamboo flooring is often more expensive than laminate, though it is generally cheaper than traditional hardwood flooring. Some bamboo floors are less sustainable than others, as they contain the toxic substance formaldehyde (rather than natural-base adhesives). [17]
Cork flooring is made by removing the bark of the Cork Oak (Quercus Suber) without harming the tree (if harvested correctly); as such, it is a renewable and sustainable resource. It is naturally anti-microbial and has excellent insulation properties, ensuring minimal heat loss and comfortable warm walking surface. Cork is resilient and 'springs back' preventing imprints due to heavy traffic and furniture, it also provides excellent noise insulation. While cork itself is low in volatile organic compounds (VOC) emissions, it is important to check the finish applied. Cork is not suitable for bathrooms, as it absorbs moisture. [18] [19]
Linoleum is made from dried and milled flax seeds mixed with other plant material (pine resins, wood flour, ground cork) with a jute backing, all completely natural materials which come from renewable sources and are 100% biodegradable. All by products and waste is milled and used. Linoleum does not fade, as the pigments are embedded in the structure. It is anti-static, repelling dirt, dust and other small particles, making it hypoallergenic – for this reason it is often used by people with respiratory issues (asthma, allergies). It is also fire-resistant and does not require additional fire-retardants finish. [20]
Rubber flooring used to be made from a rubber tree, a 100% renewable resource. Today styrene-butadiene rubber (SBR), a general-purpose synthetic rubber, produced from a copolymer of styrene and butadiene is used for "rubber flooring". It is easy to install and maintain, is anti-static and provides effective sound insulation and vibration reduction. Rubber flooring is also resistant to fading and cigarette burns. Most rubber flooring is made from synthetic rubber, which is not a sustainable product. [21]
There are carpets which are sustainable, using natural fibers such as cotton, sisal, wool, jute and coconut husk. Handmade Citapore rugs include a wide range of sustainable flooring material as these rugs are generally made from cotton (both virgin and recycled), jute, rayon and cotton chennile. It is also possible to have carpet made completely from recycled polyethylene terephthalate used for food/drink containers. Recycled nylon is also a common material used and the process takes carpet made with nylon 6 fibers and recycles it into brand new nylon carpet. This process can be repeated numerous times and in 2009 alone, Shaw's Evergreen facility recycled over 100 million pounds of carpet. This is sustainable and it reduces material sent to landfill; further it uses dyeing methods that are less polluting and require less energy than other flooring. This flooring is sustainable when used alongside eco-friendly adhesive, as some products may have toxic finishes added (stain/fireproofing) that are not considered sustainable. [22]
Coconut timber is a hardwood substitute from coconut palm trees. Coconut palm wood flooring is cheaper than teak, with the wood hardness comparable to mahogany. Coconut palm wood is made from matured (60 to 80 years old) coconut palm trees that no longer bear fruits.
Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. Floor covering is a term to generically describe any finish material applied over a floor structure to provide a walking surface. Both terms are used interchangeably but floor covering refers more to loose-laid materials.
Sustainable living describes a lifestyle that attempts to reduce the use of Earth's natural resources by an individual or society. Its practitioners often attempt to reduce their ecological footprint by altering their home designs and methods of transportation, energy consumption and diet. Its proponents aim to conduct their lives in ways that are consistent with sustainability, naturally balanced, and respectful of humanity's symbiotic relationship with the Earth's natural ecology. The practice and general philosophy of ecological living closely follows the overall principles of sustainable development.
Linoleum is a floor covering made from materials such as solidified linseed oil (linoxyn), pine resin, ground cork dust, sawdust, and mineral fillers such as calcium carbonate, most commonly on a burlap or canvas backing. Pigments are often added to the materials to create the desired colour finish. Commercially, the material has been largely replaced by sheet vinyl flooring, although in the UK and Australia this is often still referred to as "lino".
A bamboo floor is a type of flooring manufactured from the bamboo plant. The majority of today's bamboo flooring products originate in China and other portions of Asia. Moso bamboo is the species most commonly used for flooring.
Green building refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature. Buildings that live in harmony; green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.’
Underlay may refer to flooring or roofing materials, bed padding, or a musical notation.
Interface, Inc. is a global manufacturer of commercial flooring with an integrated collection of carpet tiles and resilient flooring, including luxury vinyl tiles (LVT) and nora brand rubber flooring.
Sustainable architecture is architecture that seeks to minimize the negative environmental impact of buildings through improved efficiency and moderation in the use of materials, energy, development space and the ecosystem at large. Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the built environment.
Cradle-to-cradle design is a biomimetic approach to the design of products and systems that models human industry on nature's processes, where materials are viewed as nutrients circulating in healthy, safe metabolisms. The term itself is a play on the popular corporate phrase "cradle to grave", implying that the C2C model is sustainable and considerate of life and future generations—from the birth, or "cradle", of one generation to the next generation, versus from birth to death, or "grave", within the same generation.
Design for the environment (DfE) is a design approach to reduce the overall human health and environmental impact of a product, process or service, where impacts are considered across its life cycle. Different software tools have been developed to assist designers in finding optimized products or processes/services. DfE is also the original name of a United States Environmental Protection Agency (EPA) program, created in 1992, that works to prevent pollution, and the risk pollution presents to humans and the environment. The program provides information regarding safer chemical formulations for cleaning and other products. EPA renamed its program "Safer Choice" in 2015.
Wood flooring is any product manufactured from timber that is designed for use as flooring, either structural or aesthetic. Wood is a common choice as a flooring material and can come in various styles, colors, cuts, and species. Bamboo flooring is often considered a form of wood flooring, although it is made from bamboo rather than timber.
Reclaimed lumber is processed wood retrieved from its original application for purposes of subsequent use. Most reclaimed lumber comes from timbers and decking rescued from old barns, factories and warehouses, although some companies use wood from less traditional structures such as boxcars, coal mines and wine barrels. Reclaimed or antique lumber is used primarily for decoration and home building, for example for siding, architectural details, cabinetry, furniture and flooring.
Sustainable engineering is the process of designing or operating systems such that they use energy and resources sustainably, in other words, at a rate that does not compromise the natural environment, or the ability of future generations to meet their own needs.
The global headquarters for Novus International is located in St. Louis, Missouri, in the US. The building was completed in 2009 in a design-and-build partnership with Clayco, resulting in a 90,000 square foot complex with a Platinum LEED certification. Prior to the new construction, Novus had two facilities in St. Louis, located 12 miles apart; one was the administration building and the other was the research lab.
Green building on college campuses is the purposeful construction of buildings on college campuses that decreases resource usage in both the building process and also the future use of the building. The goal is to reduce CO2 emissions, energy use, and water use, while creating an atmosphere where students can be healthy and learn.
Environmentally sustainable design is the philosophy of designing physical objects, the built environment, and services to comply with the principles of ecological sustainability and also aimed at improving the health and comfort of occupants in a building. Sustainable design seeks to reduce negative impacts on the environment, the health and well-being of building occupants, thereby improving building performance. The basic objectives of sustainability are to reduce the consumption of non-renewable resources, minimize waste, and create healthy, productive environments.
Plyboo is one of the brands owned by Smith&Fong Co., a privately held building materials company based in San Francisco. Plyboo was launched as a brand in 1993 by Smith&Fong, the first U.S. company to sell imported bamboo flooring in North America. Although Smith&Fong Co. is the parent company, Plyboo has come to be how the company is primarily identified.
Green building is a technique that aims to create structures that are environmentally responsible and resource-efficient throughout their lifecycle – including siting, design, construction, operation, maintenance, renovation, and demolition. A 2009 report by the U.S. General Services Administration evaluated 12 sustainably designed GSA buildings and found they cost less to operate.
Goodwin Heart Pine is a company located in Micanopy, Florida and specializes in reclaiming antique heart pine and heart cypress from rivers and old buildings to produce lumber for flooring, stair parts and millwork. Goodwin's product range also includes other sustainable and rare woods, including wild black cherry. Goodwin Heart Pine also produces precision-engineered wood flooring, from these specialty woods. The company has a unique focus of harvesting resin-saturated deadhead logs from rivers that loggers felled in the 1800s, which sank due to their high resin content. The interior of the reclaimed logs is typically preserved by the tree's resin.
Sheet vinyl flooring is vinyl flooring that comes in large, continuous, flexible sheets. A vinyl sheet floor is completely impermeable to water, unlike vinyl floor tile, which comes in stiff tiles, and vinyl planks, which come in interlocking strips. It is sometimes called linoleum after a visually similar product of different chemical composition.
