In extreme heat, what is the required maximum difference in degrees between indoor and outdoor temperature for an ARF?

In the context of assisted living facilities, specifically Adult Residential Facilities (ARFs), ensuring a comfortable and safe environment for residents during extreme heat is crucial. The established standard mandates that the maximum allowable differential between the indoor and outdoor temperatures is 30 degrees Fahrenheit. This means that if the outdoor temperature reaches an extreme level, the indoor temperature must not exceed that level by more than 30 degrees. Adhering to this standard helps prevent heat-related health issues among residents, particularly those who are older or have underlying health conditions, by ensuring that they remain in a cooler and more manageable environment.
