One of the most recent sustainable solutions in the construction industry is using cool metal roofing which is basically a roof designed to reflect and re-emit back sunlight and heat instead of absorbing it like other roofing materials. How Cool Roofs are Made Cool metal roofs are made from tin, aluminum, steel or copper and then covered with a highly reflective white paint, sheet covering or reflective shingles. A cool roof can stay around 55 degrees Fahrenheit during summer while ordinary roof goes as high as 150 degrees Fahrenheit reducing your energy bill by 40%. Companies like Wespol have been at the forefront of installing sustainable roofing solutions and insulation for commercial, industrial and residential buildings. 1. They Do Not Absorb Heat Unlike other roofing materials, cool roofs reflect sunlight and re-emit the heat back into the atmosphere immediately instead of absorbing it. This means that even on the hottest day, the building under that roof will remain cool and there will be no need to use an air conditioner or other cooling gadgets. The coating used in the best cool roofing can reflect and re-emit up to 90% solar radiation away from your building. 2. Prevent Urban Heat Island Effect Once the heat has been absorbed by the building and the roof, it has to be emitted slowly into the air overnight and this causes a heat island effect which means the entire area will feel hot and more power will be needed to cool. However, there is no heat absorbed by a building when you have cool roofing so the effect will be prevented. 3. Reduce Peak Energy Use Peak electricity demand happens when a lot of buildings are used too much power to cool or heat and it causes power outages. Cool roofs can prevent pea energy use and preserve your backup generator. Other Benefits of Cool Roofs Metal is very tough and durable so you will get unmatched longevity. Metal roofs can withstand the worst of Mother Nature. Metal roofs are fire-resistant and impervious to pests. Metal is highly sustainable because it can be recycled severally. Metal roofing is a great cost-saving investment that will not only benefit your household but the environment as well. It is a green home product with Energy Star and LEED Ratings so you know the benefits are real.
Savannah Coulsen posted a blog entry in Green SmartIn a culture that recycles over 150 million metric tons of metallic materials each year in the US alone, one cannot honestly say that there is no recycling effort taking place. Yet, many people are not aware of the many benefits that can be derived from a comprehensive effort to clean up the environment. Our article below covers several direct benefits produced today by scrap metal recycling operations across the US. Economic Reasons The US scrap metal recycling industry in 2008 resulted in the creation of more than 85,000 jobs and $86 billion being generated in revenue. That same year, the US exported roughly 44 million metric tons of scrap commodities that resulted in a more balanced US trade economy. Production of everyday items such as staples, paper clips, fasteners, jewelry, tools, city infrastructures and elements of buildings themselves all make up the scrap metal industry. Today, the industry is not only good for the environment, but it's good for business as well. Over 450,000 new jobs were created within the last three years at a time when the economy appeared to be in dire straits. Best of all, they were high quality, good-paying jobs that fed money back into a fragile and stagnant economy. Energy/Natural Resources Producing metals from virgin ore is an expensive process--both naturally and economically. However, the recycled scrap metal process not only reduces the amount of greenhouse gas emissions, but it also helps preserve the earth’s precious natural resources. For instance, using recycled material saves up to 92 percent aluminum, 90 percent copper and more than 56 percent of steel stockpiles. Moreover, the recycling of just one ton of steel preserves more than 2,500 pounds of iron, 1,400 pounds of coal and more than 120 pounds of limestone. In addition, one ton of recycled aluminum helps conserve 8 tons of bauxite ore and 14 megawatt hours of electrical energy. Ecological/Environmental Benefits In a concentrated effort to preserve the ecological system, one cannot stress enough the importance of having a comprehensive program for recycling of scrap metals. Being that scrap metals are as usable, malleable and less expensive to produce then virgin material, it’s crucially important to have professional recyclers do the taxing work of removal and recycling according to General Recycling Industries Ltd., one of the many Edmonton scrap yards. All things considered, there are no valid reasons for not recycling scrap metals. The scrap metal industry consistently proves itself as being cost effective for those involved inside the industry and outside of it. But more importantly, as the obvious stewards of earth’s resources, scrap metal processing just may help avoid a possible future ecological disaster.
