So Weschler and Wisthaler simulated a typical
office environment at the Technical University of Denmark
in Copenhagen — two people
in a carpeted 28.5 — cubic meter room at a temperature of 23 degrees Celsius with two
small stainless steel tables, two chairs, two flat - screen LCD monitors, two headsets, one walkie - talkie, one
small mixing fan, a few books, two
laptops, two bottles of water and ozone concentrations that reached roughly 32 parts per billion, an average exposure for a hot, smoggy day.
