Indoor design conditions can vary between different types of residential buildings, such as single-family homes, apartments, and dormitories. For example, single-family homes may require a temperature range of 68-72°F (20-22°C) and a relative humidity of 30-60%, while apartments may require a slightly wider temperature range due to varying occupancy levels and activities. Dormitories, on the other hand, may require more stringent conditions due to the high density of occupants and the need to maintain a comfortable sleeping environment.
