Main article: Early skyscrapers § The first skyscraper This section of the Field Building is erected on the site of the Home Insurance Building, which structure, designed and built in eighteen hundred and eighty four by the late William Le Baron Jenney, was the first high building to utilize as the basic principle of its design the method known as skeleton construction and, being a primal influence in the acceptance of this principle was the true father of the skyscraper, 1932. In 1932, owners placed a plaque in the southwest section of the lobby reading: Īll told six buildings were demolished to make way for the Field Building, including the Home Insurance Building. This building would be constructed and opened in parts, the first part occupying the western part of the lot and the site of the Home Insurance Building. In September 1929 plans were made by Marshall Field's to construct a large office building spanning Adams, Clark, and LaSalle Streets. In April 1929 the building was reported as having a 90 percent occupancy rate, compared to an occupancy rate of the surrounding financial district estimated at 96 percent or more. The building weighed one-third as much as a masonry building and city officials were so concerned they halted construction while they investigated its safety. It had 10 stories and rose to a height of 138 ft (42.1 m) two additional floors were added in 1891, bring the total to 12 floors, an unprecedent height at the time. īecause of the building's unique architecture and weight-bearing frame, it is considered one of the world's first skyscrapers. The building was designed in 1884 by Jenney for the Home Insurance Company. ![]() The building opened in 1885 and was demolished 46 years later in 1931. It is considered the world's first skyscraper. It was the first tall building to be supported both inside and outside by a fireproof structural steel frame, though it also included reinforced concrete. Two floors were added in 1891, bringing its now finished height to 180 feet (54.9 meters). Originally ten stories and 138 ft (42.1 m) tall, it was designed by William Le Baron Jenney in 1884 and completed the next year. ![]() The Home Insurance Building was a skyscraper that stood in Chicago from 1885 to 1931. Overall, we estimate that, for a month of social distancing, the expected premature deaths due to air pollution from personal vehicle travel and electricity consumption declined by approximately 360 deaths, or about 25% of the baseline 1500 deaths. Given these decreases in travel and electricity use, we estimate the county-level expected improvements in air quality, and therefore expected declines in mortality. Using data on hourly electricity consumption by electricity region (e.g., balancing authority), we find that electricity consumption fell about six percent on average by mid-April with substantial heterogeneity. States that imposed stay-at-home policies before March 28 decreased travel slightly more than other states, but travel in all states decreased significantly. county, we find that vehicle travel dropped about 40% by mid-April across the nation. Using daily cell phone mobility data for each U.S. This paper examines the impact that these actions had on emissions and expected health effects through reduced personal vehicle travel and electricity consumption. The COVID-19 pandemic resulted in stay-at-home policies and other social distancing behaviors in the United States in spring of 2020.
