A new study which examined how LEED-certified green buildings had performed over a 16 year period reported that the green buildings delivered $7.5B in energy savings, $1.4B of benefits in reduced greenhouse gas emissions, and a further $4.4B in public health benefits. Those health benefits included an estimate of 21,000 lost days of work avoided in the U.S. alone; other health benefits derive from avoiding an estimated 172–405 premature deaths, 171 hospital admissions, 11,000 asthma exacerbations, 54,000 respiratory symptoms, and 16,000 lost days of school in the U.S. The results are summarized in “Harvard study: Green buildings deliver nearly $6bn in health and climate benefits” ; the full study appears as “Energy savings, emission reductions, and health co-benefits of the green building movement” in the Journal of Exposure Science and Environmental Epidemiology online (Jan. 30) (restricted access). The study was commissioned by the engineering company United Technologies Corporation and conducted by researchers at Harvard’s Healthy Buildings program at the T.H. Chan School of Public Health. Buildings studied were located in the U.S., China, India, Brazil , Germany and Turkey.
Although Canada was not included in the study, on January 22, the Canada Green Building Council announced that Canada ranked second amongst countries outside the U.S. for its LEED-certified buildings, with a current total of 2,970 projects totaling more than 40.77 million gross square meters of space. The 2017 annual Top 10 Countries and Regions for LEED list is compiled by the U.S. Green Building Council to recognize LEED markets outside the U.S., which remains the largest market at 30,669 projects with 385.65 million gross square meters of space. China is the largest market outside the U.S., followed by Canada, followed by India, Brazil, and Germany. In February 2018, certification and professional credentialing services for LEED and other energy-efficiency programs in Canada will change, with the launch of a joint venture between the Canada Green Building Council and for-profit Green Building Certification Inc. Canada ( GBCI). The relationship of the two bodies is outlined in their press release .
