Look, I know that there are different factors to consider in business, and I don’t know all the reasons behind Tesla’s change. However, the first thing that came to mind when I saw that Tesla had changed the free color for a new car from white to dark grey was … [continued]
In 2010, a study by Berkeley Lab using data from NASA estimated that using “cool roof ” techniques on the roofs and pavement of all cities in the northern hemisphere could have a one-time effect of removing more than 44 billion tons of carbon dioxide — 24 billion tons from … [continued]
Mid-August. A great time for four researchers from Climate Central to publish their new report on urban heat islands—areas with high daily urban vs. rural temperature differences. Almost anybody over 60 will tell you the organization of leading scientists and journalists is right on. My city’s stats are just above. … [continued]
Originally published on ThinkProgress. By Ari Phillips. On Tuesday the Los Angeles City Council unanimously passed a building code update that will require all new and refurbished homes to have cool roofs, which use sunlight-reflecting materials. Los Angeles is the first major city to require such a measure, which was pushed for … [continued]
The last time I wrote on white roofs, the finding was that they could actually cause a net cooling. But the study didn’t take into account how much the cooling of the buildings reduced electricity demand. Looks like those electricity savings can be huge from a new study on the … [continued]
Keeping a building cool is the focus of a new study launched by the University of Melbourne and the City of Melbourne which shows that painting the roof of a building white can go a long way to reducing the interior and exterior temperatures. The research results—which will be available … [continued]
White roofs have been promoted as a simple, easy, “soft geoengineering” solution to help combat global warming for awhile now. It’s gotten the strong backing of former president Bill Clinton and current Energy Secretary Steven Chu. I thought this was a rather obvious solution we should adopt — reflect more back into space with lighter roofs. Many thought is was a good idea.
Painting roofs white in order to reduce energy consumption is hardly a new concept, but adding his name to the list of those who endorse the idea is sure to give it a boost.
