In Ahmedabad, India, Women Are Climate Leaders, Not Victims

The City Fix

During the summers, in the crowded informal settlement she calls home in Ahmedabad, India, Meenaben would lay wet jute on the floor and hay on the roof of her home to lower the temperature inside.

A geometric double roof promotes natural cooling at this Tropical Chalet


After three years of design and construction, Singapore-based firm G8A Architecture & Urban Planning has completed the Tropical Chalet, a naturally cooled home with a beautiful and functional “double roof facade.”

Scientists look for the Holy Grail: The whitest paint ever


White roofs are one of those climate solutions that sound too good to be true. Compared to solar panels and electric cars, painting the roof of a building white is a suspiciously cheap, analog way to usher in a low-carbon future. That’s why it can cool below the ambient temperature.”

Sunlight-Reflecting ‘Cool Walls’ Can Save Building Owners Big Money, Study Says


sunlight-reflecting “cool walls” could save as much or more energy than reflective cool roofs. There's no formal universal definition of what constitutes a “cool wall," said Ronnen Levinson, study co-author and staff scientist at Berkeley Lab. cool walls could lead to annual HVAC energy costs savings of up to 11 percent for standalone retail stores, 8.3 This will help you find a cool paint, stucco or cladding for your building.”

No waste, no carbon, no wonder this net-zero home breaks the mold


Additionally, a photovoltaic array on the roof generates solar power and is covered with a white cool-roof membrane. The windows are also triple-glazed and protected with deep roof overhangs.

The Invisible House is a reflective building that mirrors its desert surroundings


The building’s sustainability features include an efficient insulation system using a combination of closed cell “Cool Roof” foam and a hill-adjacent location protecting it from the sun.

A defence of geoengineering

Business Green

Historically, the proposed examples have been pretty far out - including some in the literal sense, such as the mirrored "space shade" originally proposed back in 1989 that would deflect the sun's rays - like the white, cool roof concept used for buildings only on steroids and in orbit.
