Green Technology Slide Show

  1. 1. Green TechnologySmart High Tech Roofs<br />Change Color Based on Temperature<br />
  2. 2. Green Technology<br />Encompasses a board range of subjects from new energy-generation techniques to the study of advanced materials to be used in our daily life<br />However focuses on reducing the environmental impact of industrial processes and innovative technologies caused by the earth’s growing population <br />
  3. 3. Helping the earth<br />Mainly creating fully recyclable products, reducing pollution, proposing alternative technologies in various fields, and creating a center for economic activity around technologies that benefit the environment<br />The more we recycle we are reducing air pollution and the time of making new things that we could just reuse<br />
  4. 4. Smart High Tech Roofs<br />Although white roofs are the hot thing in roofing that allow for a lowed burden on a/c systems <br />But dark colored roofs can bring solar gain to warm buildings<br />
  5. 5. Change Color Based on Outdoor Temperature<br />Roofing that can change color based on outdoor temperature to maximize of minimize solar gain<br />MIT researchers have developed roof tiles that change color based on the temperature, turning white when it’s hot to deflect heat<br /> Black when it’s cold to absorb it the tiles can reflect about 80 percent of sunlight when they’re white and 30 percent of sunlight when they’re black white state could save as much as 20 percent of present cooling costs<br />
  6. 6. How The Tiles Are Assembled<br />The system is made of a polymer in a water solution encapsulated between flexible plastic layers, with a dark layer at the back of the roofing material<br />
  7. 7. How The Roofing Titles work<br />When the temperature is above a certain level the polymer it produces a white surface and scatter light <br />Below that temperature the polymer stays dissolved revealing the title’s black backing and absorbs the sun’s heat <br />
  8. 8. Why I chose this Piece of Green Technology <br />It is a cool idea of using the sun as a source of both heating your house and cooling it<br />A great way of saving money<br />A resourceful way of using things around us to perform a simple task<br />
