What is the minimum temperature recommended for comfortable indoor working?

The recommendation for a minimum indoor working temperature is based on the need to ensure both comfort and productivity in the workplace. A temperature of 16 degrees Celsius is widely recognized as the minimum threshold for comfort, especially in environments where sedentary work is being performed. At this temperature, individuals can generally maintain comfort without excessive energy expenditure on body heat generation. It allows workers to focus on their tasks without being distracted by cold conditions, which can lead to reduced efficiency and increased discomfort.

In contrast, temperatures lower than this might lead to discomfort, affecting concentration and work performance. While temperatures like 18 degrees Celsius and 20 degrees Celsius provide an even more comfortable environment, they exceed the minimum requirement for indoor working conditions. Therefore, 16 degrees Celsius stands out as the baseline for acceptable comfort in indoor working environments.
