Researchers develop super-thin coating that could help keep buildings cool during the summer

  1. Keeping a large building cool during hot summer months is no easy task. In addition to soaking up warmth from outside, building dwellers also have to contend with heat generated from within. It's a combination that often forces air conditioning...

    Sounds promising but we have seen similar products in the past (remember the old solar reflecting insulation sheets from the 80's). How it will be applied will also be a determining factor in it's viability. Now, if you could somehow combine this technology with the newer thin film solar panels that are next generation, you could have a remarkable product. A 95% efficiency in that kind of panel would make it highly attractive for even the most modest homeowner to install.

    I work in the construction field there are a number of products like this on the market currently. Not quite as efficient but still do a good job of reflecting Infrared and reducing heat transfer. Also I would have a concern about ending up with another giant magnifying glass. Like that building in London that torched the street very noon.

    they still use that produc(alum faced foamboard/or what is basically giant alum foil as a radiant heat reflector)t. it's good, it just needs to understood. I'm in the building industry and most builders don't care to get there heads around it. I don't blame them, the industry is always promising breakthru products and they almost always fail to outperform the old tried and true stuff. Anyway, this thing here claims to go a step further and have the ability to radiant a buildings indoor heat outward. well, cool, but that's just going to need a total rethink of some major building parts. the building industry isn't yet 100% or what to do with things like humidity, so this won't be figured out overnight.
    as for this coating on solar panels, I guess you mean as a way to reduce their solar heat gain and thus lower their temp. I hear that those high temps aren't good for them or their efficient operation. plus it would be installed at the factory in ideal conditions so that might be a good.
