Green building's footprint tends to grow fastest in countries that have national policies that promote construction of sustainable, energy-efficient structures, according to a report by Lux Research. The study found that national building codes that boost energy efficiency and the availability of financial aid helped drive sustainable construction in places such as Singapore and Germany. The U.S., which relies largely on local ordinances and voluntary organizations to drive sustainable construction, didn’t land in the top quadrant of countries in the report, despite significant pockets of cutting-edge green building activity.
