Seminar 4: Limiting Humidity to Reduce Building Dampness Health Risks WITH LIVE Q&A
–
Summary:
ASHRAE’s 2019-2024 Strategic Plan extends 80% occupant satisfaction to include a healthy built environment. Excessive indoor moisture has long caused structural and material damage, and increased occupant health risks. In ASHRAE Standard 62.1:2019 (Ventilation for Acceptable IAQ) the humidity limit is a maximum dew point temperature of 15°C (60°F) rather than 65% RH (without reference to any dry bulb temperature). This requires mechanically cooled spaces to have dehumidification components/controls that limit humidity (occupied and unoccupied hours) when outdoor dew point exceeds 60°F (15°C). This impacts system design and operation to preserve IAQ and prevent damage to building materials.
