Workplace Ventilation

Recently, our firm has focused on what we can do to assist facilities in fulfilling OSHA COVID-19 requirements for workplace ventilation. Although facilities may have been tempted to open outside air dampers 100% to meet the January 6th deadline, this can cause issues with these systems in the future. Visit our Workplace Requirements: Facility Ventilation page to read the highlights of this rule, and what you should, and should not do, to meet requirements.


Our work spans a variety of sectors, all needing specific services, or a combination of services to meet their goals. Below are a few projects illustrating our capabilities.
