Indoor design conditions can vary significantly between different types of educational facilities, such as classrooms, laboratories, and auditoriums. Classrooms typically require a temperature range of 68-72°F (20-22°C) and a relative humidity of 30-60%, while laboratories may require more stringent conditions due to the presence of sensitive equipment and experiments. Auditoriums, on the other hand, may require a wider temperature range to accommodate varying occupancy levels and activities.
