Redefining healthy buildings

Pathian specializes in commercial building pressure control.  If you experience drafts in hallways, stairways, or open areas, your building is telling you it has HVAC mechanical system inefficiencies. Not only is your comfort and productivity affected but unmitigated airflow can increase the threat of airborne infectious disease, especially in hospitals.

IAQ redefined...

Do you think your building environment has good indoor air quality (IAQ)?  Recent studies using the latest in technology metagenomic tools reveal that commercial buildings house more strains of pathogens than once thought.  Like hundreds of orders of magnitude higher than what could previously be measured using traditional petri dish measurement techniques!  Use of these new measurement tools have also led to the discovery that many of these newly discovered airborne pathogens are highly impacted by humidity levels in the air.  Low humidity levels can greatly extend their life while making them lighter, thereby allowing them to be carried much further distances by HVAC systems.  Low humidity levels also negatively impact building occupants more than what was previously understood. Studies confirm that when humidity levels are outside the 40%-60% RH window building occupants may face at a minimum:

  • Lower immune system efficacy
  • Elevated stress levels & lower productivity
  • Sleep deprivation
  • Higher risk of catching airborne infectious diseases

Are you starting to see IAQ from a different perspective?

Airside optimization's role on humidity control

Hopefully you are beginning to understand the important role humidity plays in good IAQ.  What does that have to do with your building’s airside system optimization?  Plenty!  Inefficient HVAC airside systems vent conditioned air you already paid to heat, cool, and humidify back outside.  So much so that in many cases your commercial building’s humidification systems can’t keep up resulting in dangerously low humidity levels in the winter months.  Pathian addresses these inefficiencies with its Airside Optimization System (AOS).  Our analytics identify the root cause and show how much energy is being wasted.  Our automated engineering and proprietary building pressure control software can then be used to correct the problems.  We see typical return on investment in less than three years.  The energy savings continue for the rest of your building’s lifecycle!

Not surprisingly, Covid has ignited a renewed interest in the science of indoor air quality for commercial buildings.  Don’t expect this hot topic to cool any time soon.  One of the most respected and well informed voices in this field is Dr. Stephanie Taylor (M.D., M.Arch, CIC) who is now recognized as one of the nation’s foremost researchers on airborne viral infections in buildings.  Check out this ASHRAE interview with Stephanie as she discusses metagenomic testing and the effects of humidity on IAQ!
