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. » Read more: Eco-Homes: Why Durable Zinc Is the “Green” Solution for Residential Roofs
