The temperature at which point condensation begins is known as what?

The term that defines the temperature at which condensation begins is "Dew Point." This is a critical concept in building science and environmental conditions, as it indicates the specific temperature at which air becomes saturated with moisture, leading to condensation. When the air temperature drops to this point, water vapor in the air condenses into liquid water, which can have significant implications for moisture management in buildings and indoor environments.

Understanding the dew point is essential for addressing issues related to humidity and condensation within multifamily buildings, particularly in climates with varying temperatures and moisture levels. By monitoring and controlling indoor humidity levels and temperatures relative to the dew point, building analysts can contribute to better energy efficiency and occupant comfort while preventing problems such as mold growth and material deterioration.

In contrast, other terms like Frost Point, Boiling Point, and Condensation Point do not accurately capture the specific condition of air saturation with moisture leading to condensation at the dew point.
