PATRICIA McARDLE wrote this opinion piece for the New York Times:

“American taxpayers’ dollars are also being used for energy-inefficient construction projects. During my year in Afghanistan, I sat for hours in meetings with local officials in remote mountain and desert locations, sweating or freezing — depending upon the season — inside concrete and cinder-block schools and police stations built with American aid. These projects are required to adhere to international building codes, which do not permit the construction of traditional earthen structures.”

“These structures are typically built with cob — a mixture of mud, sand, clay and chopped straw molded to form durable, elegant, super-insulated, earthquake-resistant structures. With their thick walls, small windows and natural ventilation, traditional Afghan homes may not comply with international building codes, but they are cooler in summer and warmer in winter than cinder-block buildings. They also last a long time. Some of Afghanistan’s oldest structures, including sections of the defensive wall that once surrounded the 2,000-year-old Silk Road city of Balkh, are made of cob and rammed earth. In England, people are still living in cob houses built before Shakespeare was born.”
