HVAC Design For Indoor Air Quality Optimal Health, Comfort, and Energy Efficiency We can improve the Indoor Air Quality in our homes, schools, and workplaces. Optimal temperature and humidity, adequate filtration, and proper ventilation are all proven solutions to achieve quality indoor air. 1. Ventilation Use an Air Flow Measurement Station (AFMS) to ensure optimal fresh air ventilation across all airflow rates. Utilize zone level alerts. 2. Energy Recovery Exhaust stale building air while recovering energy. Options include: rotary wheel, fixed plate exchangers, heat pipe systems, and pumped run-around. 3. Filtration Pre-Filters – Initial Stage Media, Various Efficiencies. Advanced Filters – High Efficiency Media, Activated Carbon. 4. Coil Treatment Constructed with special materials and/or provided with protective coatings to limit microbial growth. Ultraviolet Light (UVC) for surface treatment of coil and condensate pan. 5. Dehumidification Cooling coil provides primary humidity removal. Re-heat options to avoid over cooling are available. Options for run-around, precooling, reheating systems. 6. Humidification Technologies for increasing and maintaining healthy levels of humidity: steam, adiabatic / evaporative, and atomizing. 7. Final Filtration Added stage of protection in the AHU, up to 99.99% HEPA. 8. Sterilization / Purification Application of advanced technologies for air treatment of biologicals, chemicals, smoke, and/or odors.
