Presentation Topic/Summary: Indoor Humidity and its Impact on Buildings and Occupants
Effective humidity control is fundamental to delivering high-performance buildings that are safe, durable, energy-efficient, and compliant with modern standards. Yet, moisture-related failures—ranging from microbial growth and IAQ degradation to material deterioration and system inefficiencies—remain among the most persistent and costly challenges faced by HVAC engineers.
This presentation provides a technically grounded exploration of indoor humidity through the lens of applied psychrometrics and building science. Attendees will gain a clear understanding of how moisture is introduced, transported, and stored within buildings, and how these mechanisms influence both HVAC system performance and the built environment. Drawing from key ASHRAE resources—including guidance on damp buildings, human health, and HVAC design—this session connects fundamental principles to real-world engineering applications across all climate zones.
With a focus on practical implementation, this presentation equips HVAC professionals with the knowledge needed to proactively manage humidity, mitigate risk, and design systems that support long-term building performance and occupant well-being.
Learning Objectives
After attending this session, participants will be able to:
- Define and apply ASHRAE-recommended indoor humidity limits to minimize the risk of condensation, microbial growth, and moisture-related building damage.
- Differentiate between key psychrometric parameters—including relative humidity and dew-point temperature—and apply them appropriately in HVAC system analysis and design.
- Evaluate moisture behavior within building systems, including surface condensation, absorption/adsorption in materials, and vapor diffusion through assemblies.
- Incorporate humidity control strategies into HVAC system design to improve indoor environmental quality (IEQ), system reliability, and overall building performance.
