| Abstract | The energy crisis, global warming and the rising temperatures in cities: these are problems that are becoming more salient in the United States. And now with a new energy-conscious president, the idea of a fresh start finally seems plausible. Most of the solutions are not new: cut down on carbon dioxide emissions by driving less, use public transportation and find alternatives to oil. However, it is somewhat rare to hear about other innovative and sustainable practices that cut down on CO2 emissions. Though green roofs have an obvious aesthetic function, the connection between installing vegetation on roofs and CO2 reductions is not as widely understood. Green roofs help reduce CO2 emissions because vegetation, as opposed to hard concrete, absorbs relatively less sunlight, which reduces internal temperature of the building and the surrounding air. By reducing the building's temperature and mitigating the "urban heat island" effect, less energy is required to cool the building. While green roofs provide many needed benefits, cool roofs have also shown to decrease building energy consumption. Cool roofs, or roofs painted white have been a popular cooling technology since the Ancient Greeks used them to keep their homes cool, but more recently roofs have fallen out of the energy debate. The current popular way to decrease energy usage is primarily centered on changes inside the home -- installing LED light bulbs, more efficient appliances and cooling systems. But there is an easier and cheaper way to cut back on energy costs: just look up to the roof. |
