A new high-tech paint from SolCold that cools when exposed to sunlight could provide a better way to cool buildings and perhaps even solve the long-standing problem of cooling things in space. In hot weather, electricity consumption soars as people turn on the air conditioning, pushing the grid to its limits and raising energy bills. The SolCold technology uses a double-layered coating to reduce temperatures by up to 10 degrees C below those attained with traditional white paint coating. The paint has tested well in the lab, with some caveats-so far it works better on metal roofs than concrete, and is more successful over rooms with low ceilings than high ones. Although this paint is more expensive than standard options, it?s said to offer quite substantial energy savings- a decrease in energy consumption by up to 60 percent, while lasting 10 to 15 years before needing a new coat. The first clients are thus expected to come from the business world.
