Through proper diagnostics, a baseline understanding of the condition and performance of a mechanical and air distribution system can be established. From this baseline, an informed plan can be developed to clean, restore and maintain the HVAC system to supply healthy, pathogen free indoor air quality.

When engaging in indoor air quality projects, understanding the diagnostics of buildings before investing in the work has many benefits that include: reducing environmental risks, more accurate maintenance planning, accountability and compliance, ensuring occupant safety and improving overall staff confidence.

When assessing indoor air quality, a holistic approach is imperative while keeping in mind the EPA and CDC if there are outbreaks is advisable.

Assessments should cover the whole gamut of indoor air quality parameters including building baseline conditions, HVAC hygiene and performance, IAQ product efficacy if any products are used inside the building envelope and indoor air quality monitoring. Once the data has been obtained, best practices lean on utilizing the information before executing maintenance in order to optimize work and focus on the areas that need it the most.

The building microbiome contains an intricate balance of healthy constituents and unhealthy contaminants that can be targeted and eliminated upon discovery. They include allergens, bacteria, mold and viruses. Testing the wall and floors for moisture as well as measuring overall temperature and humidity all play a role in the health of a building. Performing the envelope test and balance is also an integral part of the evaluation process. Facility managers could do everything right to correct the deficiencies on the interior, but if the exterior is not addressed then they have put themselves in a double-edged sword position.

In this session, Frank Santini, director of education and strategic initiatives for Pure Air Control Services, Inc. discusses the importance of baseline IAQ and clean air distribution systems.
