Draft Cool Roof Roadmap Now Available for Review!

Flat pack house said,

The draft proposed standards for roof insulation, for example, are rife with flayed assumptions, inaccurate cost estimates, and impracticalities that betray their origins outside the “real world" of actually installing roofs.

President Obama was at Penn State today talking about building innovations. Thank you for letting me review the road map in draft form. As an innovative American, I suggest evaporating water through hydrophlic rocks for cooling with be included as a way to effectively cool building roofs and walls to near local area wet bulb air temperature (below air temperature). Of all the science the draft puts forward I found nothing that comes close to an operational temperature of 86*F on the hottest part of the day on the hottest day of the year. Unlike the 40% reduction in effectiveness of 'cool roofs' over time, as the draft states, water cooling provided constant wet bulb temperature tracking every day for years of operations. To support water cooling in modern cities I would like to bring your attention to:

"Japanese architect Mitsuo Nakamura believes that creating energy efficient buildings is the key to 21st century architectural design. His recent design of the new Sony Building in Tokyo is intended to do exactly that. It is clad in a bio-skin of porous ceramic pipes which circulate around the exterior and collect rainwater. In the hot weather, the water evaporates and lowers the temperature not just of the building itself but of the surrounding area."

Wet rocks range from bright white to sparkling black, sparkling black coating operational high temperatue is about 90*F in Florida but effectively captures solar heat when water is not added for winter time heating and summer time cooling.
