Quantifying the Implications of Green Design (10-04-18)

MacNaughton and colleagues quantified some of the benefits of environmentally responsible design.  They “calculated year by year LEED . . . certification rates in six countries (the United States, China, India, Brazil, Germany, and Turkey) and then used data from the Green Building Information Gateway (GBIG) to estimate energy savings in each country each year. . . . LEED accounts for 32% of green-certified floor space and publically reports energy efficiency data. . . . Based on modeled energy use, LEED-certified buildings saved $7.5B in energy costs and averted 33MT of CO2, 51 kt of SO2, 38 kt of NOx, and 10 kt of PM2.5 from entering the atmosphere, which amounts to $5.8B (lower limit = $2.3B, upper limit = $9.1B) in climate and health co-benefits from 2000 to 2016 in the six countries investigated. The U.S. health benefits derive from avoiding an estimated 172–405 premature deaths, 171 hospital admissions, 11,000 asthma exacerbations, 54,000 respiratory symptoms, 21,000 lost days of work, and 16,000 lost days of school.”
