Researchers at Stanford University's Ginzton Laboratory recently developed an innovative material that helps keep buildings cool. As of right now, A/C accounts for about 15 percent of the total electricity demand in the US. This new building material could help to stem the need for A/C and ultimately reduce electricity consumption.
The new technology was developed by Aaswath Raman as a means of trying to keep buildings cool from the inside. Raman's building material is an ultra-reflective surface made from layers of silicon dioxide, hafnium oxide and silver. The material works to bounce heat off of a building and back into the atmosphere. By preventing the building from heating up in the first place, the technology ultimately reduces the need for subsequent cooling.
Although the technology has yet to be put to use, the coating could help to keep buildings cool and reduce our dependence on air conditioning.
