International. A recent report by McGraw-Hill Construction estimates that among its respondents — which included architects, consultants, contractors, engineers and building owners from 62 countries — "green" accounted for an average of 38 percent of construction activity in 2012, with 94 percent of companies reporting that they engage in a certain amount of activity in this segment.
This suggests an increase from 2009, when 67% of respondents claimed some involvement in green building. Among the countries for which the 2012 report presented specific results, green construction accounted, on average, for more than half of all project activity in Singapore (66%), the United Kingdom (52%) and the United Arab Emirates (UAE, 51%). The significant and growing global interest in green building services is also demonstrated by the large number of countries with green building councils.
Green building services also represent a significant and growing share of the U.S. construction and design market, reportedly accounting for 48% of the value of total U.S. project activity in 2012.
IBISWorld estimates that revenue from the U.S. green construction industry grew at an average annual rate of nearly 27% to $87.1 billion between 2006 and 2011. The most recent data published by Engineering News-Record indicates that revenue from the top 100 leading U.S. green contracting companies reached $50.0 million after an 11.9% increase during 2012-13, while that of the top 100 U.S. green designers was $4.7 billion after a growth of 13.3%.
