The urban heat island effect and how cool pavement can help

Picture 2013-01-28 at 1.12.19 PM

On sweltering days you can fry an egg on them. But, now, Lawrence Berkeley Lab and UC Davis researchers are testing surfaces designed to make them cooler and safer.

“Cool pavements are paved surfaces that are more effective at reflecting sunlight. So, by reflecting more sunlight than traditional paved surfaces, they’re able to absorb less heat from the sun and keep cities and communities cooler.  We’ve teamed with industry partners and we’re hopeful that this can get the ball rolling on some local government action for cool pavement.”

How nanotechnology can boost energy efficiency

windowResearchers at the Lawrence Berkeley National Laboratory have developed a nanocrystal material that could add a critical energy-saving dimension to “smart window” coatings.

“We’re really excited about our technology using a solution-based process because that has the potential to really bring the costs down to the point where it can be deployed broadly in the market.”  – Delia Milliron, researcher at LBNL

Seastars are the canaries in the coal mine for climate change

At the Bodega Marine Lab, Eric Sanford studies sea stars and mussels to determine how climate change will affect ecosystems along the California coast.

“Our results suggest that if during the summertime there are more warm events, which is what’s predicted by climate models to occur along the California coast, then this can have a really big effect on these marine ecosystems.  What we found is that sea stars are actually really sensitive to small changes in temperature, so if the sea stars experience these moderately warm low tides, they get really stressed out and they consume fewer mussels and end up growing a lot less.”  – Eric Sanford, UC Davis Bodega Marine Lab
