green, help save the planet as well as money. This is because of something called the island effect. According to the UAB Reporter Archive, island is a term describing the phenomenon in which urban and suburban temperatures are 2 to 10 degrees Fahrenheit (1 to 6 degrees Celsius) hotter than nearby rural areas.
At first consideration, green roofs Converse Dainty Black Sale
Elevated temperatures alter communities by increasing peak energy demand, air conditioning costs, air pollution levels and heat related illness and mortality. Reflective and vegetated roofs cool their surroundings both directly and indirectly. In addition to direct cooling effects, such roofs reduce the need for fossil fuel based power to run air conditioners, which Converse Blue Black
This brings me to James Hrynyshyn and his Switch talk. It turns out that green roofs are one of the many switches we need to make in order to combat climate change. Secretary of Energy Dr. Steven Chu advocates them, estimating that we could save $735 million per year if 85% of our air conditioned buildings had white or reflective roofs.
in turn reduces emissions of carbon dioxide and thus lessens the impact of future global warming.
Green roofs and climate change
We certainly seen utility bill savings at Education Corporation of America, where we install Thermoplastic Olefin (TPO) white membrane insulated roof systems at all of our campuses.
You probably wondering what I was doing on a roof at UAB, in the middle of the day, during yet another of the hottest springs on record. Along with Hrynyshyn and UAB Scientists and Engineers for America chapter president Desmond Villalba, I was touring Hulsey Center roof.
One of them was from the roof of the University of Alabama at Birmingham (UAB) Hulsey Center. The Women Converse Fashion other was from Big Switch, presentation by James Hrynyshyn, science blogger of M blog fame.
is a green roof? you might ask. Well, green roofs are green in the literal sense, thanks to the presence of live plants. They are also green in contemporary social contexts, in that they save money while being ecologically friendly.
Dr. Peters compared natural gas, water and electricity bills for the Hulsey Building four years prior to the green roof installation in July 2008 with those following the installation. The green roof has shaved between 20 and 25 percent off utility expenses, far exceeding UAB Facilities expectations!
may seem like a bad thing. I mean, in the past, stuff growing on your roof was an indication your roof had problems. But UAB roofing specialist Roger Brown designed the Hulsey Center roof with several layers under autoclave aerated concrete, including a polypropolene type liner, a Styrofoam type insulation, and a plastic that looks like an egg carton. This roof can hold 6,000 gallons of water, and it is designed to catch the rainwater and delay its release to minimize the potential for flooding. The design has even captured the attention of the Alabama Department of Environmental Management, which is interested in promoting green roofs throughout the state.
