Energy Saving Building Codes

Cities, states, and countries are develop increasingly tough energy-saving building codes for new buildings to save energy and fight global warming. The U.S. Energy Department estimates that 40% of the carbon dioxide emitted in the U.S. comes from buildings and their appliances. While energy-saving improvements are costly at the outset, they can save on gas and electricity bills over time. The New York Times has an interesting article about these new green building codes and the people who enforce them.
