As unchecked global climate change turns up the temperature, that could mean even more sick or injured outdoor workers. Miami-Dade County experiences about 133 days a year where it’s over 90 ...
For this model the standard provides a graph of acceptable indoor temperature limits at prevailing mean outdoor temperatures (a mean of the daily mean outdoor temperatures of the previous 7–30 days). An accompanying table lists provisions for higher operative temperatures at air speeds above 0.3 m/s (59 ft/min) and up to 1.2 m/s (240 ft/min).
The state's new requirements won’t protect all indoor workers there, however: Officers at state and local correctional facilities, as well as other prison employees, are excluded for the time being.
A digital thermometer reading an ambient temperature of 36.4°C (97°F) in an unventilated room during a heat wave; a high indoor temperature can cause heat exhaustion or heat stroke in a person. The World Health Organization in 1987 found that comfortable indoor temperatures of 18–24 °C (64–75 °F) were not associated with health risks ...
Assuming an outdoor temperature of 95 °F (35 °C) and an indoor temperature of 80 °F (27 °C), the above equation gives (when temperatures are converted to the Kelvin or Rankine scales) a COP of 36, or an EER of 120. This is about 10 times more efficient than a typical home air conditioner available today.

The building balance point temperature is the outdoor air temperature when the heat gains of the building are equal to the heat losses. [1] Internal heat sources due to electric lighting, mechanical equipment, body heat, and solar radiation may offset the need for additional heating although the outdoor temperature may be below the thermostat set-point temperature.
