Verify Engineering
and HVAC Controls

 

At the cutting edge of building science, health science, and data science, veriDART™ is the first and only liquid aerosol-based solution for verifying air ventilation and filtration in order to protect occupational health during the pandemic and beyond.

Unprecedented Challenges, Inadequate Solutions

SARS-CoV-2 is unlike any traditional indoor air quality challenge. Infectious aerosols become mobile in buildings via airflows generated by HVAC mechanical systems, creating an invisible, unpredictable, and potentially deadly risk to occupants.

Existing diagnostic solutions for indoor air quality are geared towards solid and gaseous contaminants, not liquid aerosol-based risks like SARS-CoV-2. Computational fluid dynamic models are valuable for theoretical understanding of airflows, but not always applicable to the unique, dynamic nature of real-world environments. And surface and air tests for SARS-CoV-2 indicate viral presence, not mobility. Inadequate solutions result in safety and facility professionals operating blindly with enormous occupational health and financial consequences at stake.

Test and Verify

veriDART’s proprietary airborne tracers safely mimic the chemical composition, mobility, and effect of ventilation and filtration for aerosol contaminants to deliver powerful, actionable decision-making analytics. The veriDART adheres to the highest levels of product safety and is well below the OSHA, NIOSH, and ECHA safe exposure limits.

See how the veriDART works below.

Plan A unique test plan is developed based on a customer’s assessment needs, which fall into the following categories - survey test dilution ventilation test or filtration test. Spray Qualified professionals release airborne tracers in designated test areas. Circulate Airborne tracers disperse through building spaces and air ducting. Sample Air samples are collected and tested at selected points and time periods. Results A diagnostic report provides heat map visualizations and dilution & filtration curves to guide engineering and HVAC control decisions.

Ventilation and Filtration

We confirmed the customer’s expected performance of its ventilation and filtration in many instances, with our tracers traveling widely throughout the buildings and often not being caught by existing filters. However, these results informed critical decisions around modifications and upgrades.

Restrooms, Conference Rooms, and Other Enclosed Spaces

 We established clear time and condition parameters at which tracers reduced to lower risk, safer levels, surprisingly varying across spaces with similar size and HVAC system configurations. Additionally, we identified mechanical deficiencies in the HVAC system in several rooms.

High Airflow Pathways

We identified several high airflow pathways, which coincided with open office areas, break areas, and other high-trafficked areas. Additionally, we identified several unexpected high airflow pathways involving higher risk areas that were exhausting into lower risk areas.
