Efficient Buildings Could Save Thousands of Lives in U.S. Every Year

23. 8. 2021 | Yale School of the Environment | environment.yale.edu

Buildings in the U.S. are responsible for 40% of the country’s total energy consumption. By improving the energy efficiency of new and existing buildings, the emissions generated from heating and cooling them could be reduced – preventing thousands of premature deaths every year.

A new paper published in Science Advances, authored by Yale School of the Environment Economics Professor Kenneth Gillingham and colleagues at Yale’s SEARCH Center and the Yale School of Engineering and Applied Science, lays out two building efficiency improvement scenarios and estimates for how many premature deaths in the U.S. would be prevented in each case. The burning of fossil fuels, in addition to greenhouse gasses, releases large amounts of harmful airborne particulate matter called PM2.5 (particles with diameters of less than 2.5 micrometers), which can cause heart and lung disease and aggravate conditions like asthma. The reduction in premature deaths is primarily due to the reduction in PM2.5.

Higher efficiency of buildings

The “optimistic” scenario, the authors say, envisions a 50% increase in appliance efficiency (everything from refrigerators to boilers) and a 60-90% increase in the efficiency of buildings’ outer shells by 2050. The researchers estimate that up to 5,100 premature deaths would be prevented yearly if those conditions were met. The “intermediate” scenario – still “a big step up” from what is being undertaken today, says Gillingham – could save up to an estimated 2,900 lives each year.
