Sustainable or “green” buildings – buildings that are deliberately designed to the natural resources in a manner that is environmentally friendly – no longer a luxury. They are a must.
Consider the facts. Consume according to the National Institute of Building Sciences Whole Building Design Guide “, building on an annual basis in the United States of America, 39 percent of the energy and 68 percent of its electricity elsewhere, buildings emit 38 percent of carbon dioxide (the primary greenhouse gas associated with climate change) , 49 percent of sulfur dioxide and 25 percent of the nitrogen oxides into the air. Currently, the vast majority of the energy is produced from nonrenewable resources of fossil fuels … “
To reduce by the two possibilities, heating load, cooling and lighting “of climate change response design and construction practices,” which recommends whole building design guide, the use of “high performance building envelope: the Select walls, roofs and other components on the long-term isolation and durability requirements. “
One of the most durable high performance materials of the building spread over the whole world is zinc.
Zinc is regarded as the 23rd most abundant element in Earth’s crust be. It is a non-ferrous metal, which is not susceptible to rust and corrosion: It is weather resistant, earthquake-proof, corrosion-resistant and resistant to the harmful effects of UV rays without a long very long life quality loss.This is possible because the zinc-architecture develops its own protective layer as zinc carbonate hydroxyl. Once it is formed, the layer blocks moisture and chemicals from entering the zinc and if it is scratched, the hydroxyl-carbonate is to reform over time. In other words, the zinc is recovered. Therefore walls and zinc roofs last an average of 80 to 100 years.
Zinc also very little energy to manufacture and little or no maintenance and is 100 percent recyclable scrap from new construction at the time it reaches its final use. Therefore, the zinc roofing and siding are not end up in landfills.
For generations, the European architects zinc as a material for the building envelope for all types of buildings specified, because it would take and endure extreme weather conditions. In the late 1700s, zinc was also one of the most popular materials for roofs in America, had used so many famous historical buildings such as the Washington Monument and Thomas Jefferson’s Monticello said metal roofs.
Unfortunately, zinc fell into disfavor developed in the United States as a less expensive roofing materials like asphalt shingles, and that U.S. developers and builders in the “disposable” mentality died in the 1960s and 70s, which lasts more than a 30 -, the life of 50 years for the U.S. buildings.
Today, the American architects have become in love with the material, not only because of its durability, but also because of the growing need for green design and construction.
American architects are the use of zinc in commercial, institutional and governmental warming. A few farsighted practitioners are also encouraged to use their residential architecture zinc for their house – all new construction to renovation and restoration of history.
New: think of the future
“Zinc ultimately cost much less than asphalt shingles in the calculation of the lifetime of the house,” said Daniel Schoenberg, director of market development for VMZINC and an associate member of the American Institute of Architects (AIA). “Shingles is usually made of asphalt, a decidedly non-green material and a shingle roof must be made in form to be replaced about every 10 years – four to five times over the life of a roof of zinc.”
Compared to other metals that are less expensive than zinc (painted aluminum, for example) or can be costly (copper), insists that zinc Nicely happens in the analysis. He said:
• Painted materials can rust and scratches when they are not protected or if they are damaged and their lifespan is half to one third of the zinc.
• The copper now costs about twice as zinc.
• Some communities have raised concerns regarding the discharge of copper. Zinc runoff is clear and leaves no stain adjacent materials such as copper.
• More zinc is found naturally in the earth than ever performance of a typical residential roof.
• Zinc is not bio-available as soon as it hits the ground, to post no danger to children or pets.
• Ceramic tile and slate are heavier than zinc and need a strong, a structural basis more expensive than zinc.
A zinc roof is also energy efficient cheaper than asphalt shingles, because it blocks the heat and reflects heat transfer in attics. Research by the Florida Solar Energy Center in 1985 showed that metal roofs, typically 34 percent less heat than asphalt shingles absorb and homeowners switching to metal roofing reported saving up to 20 percent on their electricity bill.
In Greenville, North Carolina, the residence of Walter’s, a sleek, modern residence of Tonic Design + Construction is developing is an excellent example of the use of zinc in an ecological architecture, energy conservation at home. Both the client and design team presented the house as a model for environmental sensitivity and choice of materials was critical to their success. For this purpose, said the designer Vincent Petrarca, Associate AIA, in 1500 square meter panel locking VMZINC flat double height of the house “public” space.
“The color, the quality of materials, and the system of interlocking panels of a detailed surface structure and create shadows on the outside of the space of two floors of the public house,” said Petrarca. “To achieve the goals of Homes Silver LEED project, we chose zinc as a central element in the composition of the external materials. It is not only 100 percent recyclable, but also durable and low maintenance with a life of almost 100 years. It was very attractive to customers. “
The “House of Greenville,” as its creators call it, is now a LEED for Homes Silver certification and Energy Star have been at home and has featured in Architectural Record in April 2010. The project also won a 2010 AIA NC COTE (Committee on the Environment) Design Award of the environment, and this year received a trophy from the President of the Association of Metal Manufacturers. The judges for the latter, “applauded the choice of using zinc, do in the face of persistent features of the manufacturer would.”
As a native of Greenville, which is also an aesthetic problem for designers, the zinc roofs and facades as a durable product designed for modern and traditional styles, which fits very nicely with other materials, see construction. Zinc metal is very malleable, so it is with a variety of architectural styles that can meet angular and curved. Zinc plates are manufactured in a variety of shapes, undulating waves of parallel ribs and interlocking hexagons, thus adding another to give an artistic element to the roof of a house or a block.
In his blog, “Life of an Architect”, Dallas, Texas, architect Bob Borson introduced in August 2011: “Despite the fact that zinc is the metal, there is a stunning visual, and physical softness.” When he wrote that he was waiting for was the installation of metal plates with zinc standing seam on a modern housing project he designed for the insertion to be seen. “We are actually two different colors on the job,” he says, “a beautiful gray zinc and quartz called a state of mind called Black Anthra Zinc explode.” Both are products VMZINC Umicore. “
New Caanan, Connecticut, Moore + Partners Architects Joeb combined zinc and cedar cladding to create a house 5300 square meters of “inclusion of contemporary technologies and environmentally friendly products.” The exterior of the house on three levels is enlivened by the juxtaposition of gray zinc and warm, honey-colored tone of cedar siding.
Residential renovation
The renovation is a growing segment in residential applications of zinc. Many pre-war homes in the United States had roofs made of tin or lead. Its replacement by zinc maintains the appearance of original materials with the benefit of modern life and value the life of a shelter for low-maintenance products.
“As more and more homeowners the quality and sustainability of the cost in select apartment renovations, they choose zinc to other materials,” said Schoenberg, noted that the products for the renovation of the building has a living standard part of the company VMZINC. “We saw the zinc for households and small porch and a large plot houses used. It is often used for fireplace surrounds and selected kitchen counter, and with a capacity of rain water.”
Ornametal Manufacturing LLC products with VMZINC rain water into its product range EuroGutterUSA 2011th The company manufactures a complete system, including rain water half-round gutter, seamless weld downspouts and accessories VMZINC natural QUARTZ-ZINC-and zinc-ANTHRA.
“Rain VMZINC products are a popular choice for those who fit charcoal gray rather the rest of the house,” Guenther Huber, President of ornametal said. “We find that the more people prefer the look of zinc, especially given the high quality and longevity.”
Historic Restoration: a sustainable value for Heritage Homes
“An aerial view of Paris shines with the natural patina of zinc,” wrote Cristin TLC Conger in an article titled “Zinc is the new standard for green building?” She goes on to say. “In the late 1800s, zinc was the material of choice for metal roofs of Paris once sharpened the melting process of zinc metal, the metal mainly in Belgium, France and Germany, two hundred years later popularized. Some of the original roof still the crown of the historic monuments. “
Zinc is a viable and non-toxic for Cultural Heritage / historic homes designed to forever as part of the architectural heritage of the nation – recognized adopted, that the Europeans simply and early American designers and builders, including Thomas Jefferson. Be a roof, which last up to 100 years and essentially maintenance-free, seems an obvious choice for a historic home, particularly as the current metal-alloy has been improved and standardized and therefore assumed an even more sustainable than ever before.
“A 80 – life of 100 years is zinc material heritage,” said Dan VMZINC very nice “A house with zinc is to last for generations.”.
In a guide to selecting the materials of the roof and repair of historic buildings in the United States, in the old house journal, Sarah Sweetser of the National Trust for Historic Preservation published restrictions, “A poor roof enables the accelerated deterioration of historic building materials – masonry, wood, plaster, paint -. and carry out general disintegration of the basic structure “
In 2006, John Leeke, a consultant for the Heritage Home Works.com Portland, ME, written at a conference on the roof repairs in the post-Katrina New Orleans: “It is my experience that long-term damage is often caused by modern building materials are introduced into historic buildings. “
The value of zinc was low maintenance factor at the University of North Carolina at Greensboro, where the decision was made to use zinc for two projects there was emphasized, including accommodation and Humanities Research Board. The university confirmed that the construction budget will be funded well tended, but not the maintenance budgets. The characteristic self-healing zinc is another factor in deciding how the aesthetic:
“Zinc is to appear on the right,” Andy Calloway Johnson Moore & West Sykes, AP, North Carolina, said project manager for the room for the Humanities project. “” The color was similar to that of the history of the roofs are in turn coated with mixed roofs as the traditional campus “(Source: McGraw-Hill Construction, Continuing Education Center).
The aesthetic quality of architectural zinc for historic buildings was a key issue for the Central Presbyterian Church in Huntsville, Alabama, where he was the house Cooper, an antebellum house next door, which is on the National Register listed renovated historical sites, to his new family life Center has become. The old house needed a new roof and rain water system that is in line with the historical style of the house and the last in the future.
Hays Buchanan, the architect on the project of the Church chose VMZINC natural “historically correct for color, gray strength and durability,” says Design & Build With Metal.com recently.
While zinc is often used in contemporary applications used, the Cooper House project is a perfect example of why there is a natural choice for the restoration of historical color, in this case VMZINC natural aesthetics historically accurate, durable and designed to last decades. Moreover, production techniques allow the unique look of natural metal to keep consistent with colors. Natural VMZINC can not develop a patina radically different, such as copper, changes its color from copper to green. Rather, it is times over the years to form a textured patina.
Design and Build with Metal.com also reported that the Central Presbyterian Church and the leaders of the Society of Huntsville / Madison County Historical “easily approved the application [of zinc roofing and rainwater system] to be compatible with the historic architecture of the building . “
Is the private use of zinc sweep in America?
After astonishing beauty, value and durability of the architecture replied zinc, Dallas architect Bob Borson the question he knew would like blog readers ask: Why is zinc no longer used in residential design?
“The reason why we will not use it more frequently because of the price,” Borson said. “For standing seam in the average cost for materials and labor in the proper execution of the range of 20 dollars per square foot will be.”
For a young family to build their first home, or elderly people to the roof of a house they have lived in over 50 years to replace, the costs are prohibitive to understand. But for new, modern homes from North Carolina to California, elegant estates in the north-east or north-western United States, a renovated farmhouse in the middle of the century or older in Florida or Kentucky, or a historic house in the heart of Charleston, Savannah, is New Orleans French Quarter, et al, the pure beauty of sustainability, and zinc for roofs and walls in popularity, as is the principle of sustainable development, energy saving houses and win more.
