“By installing cool roofs, air conditioning use could be cut by about one-third in warm regions, estimates Lawrence Berkeley National Laboratory. If all large North American cities — those with populations above 1 million — adopted passive cooling on roofs and pavement, we’d prevent the equivalent of the world’s total annual greenhouse gas emissions, or 57 billion tons of carbon dioxide.”
We’re building roofs wrong. A different approach can save money and lives.
