Piera partners with our customers to ensure compliance and reduce energy costs.
Working closely with our customers, Piera leveraged the industry’s most advanced air tracer technology to monitor air health and certify indoor spaces providing fast, accurate, comprehensive, air wellness data.
Piera’s state of the art particle sensor is a breakthrough in measuring the smallest particles below 1.0-micron cost-effectively. Piera’s custom particle processor was developed originally for x-ray devices to ‘count and size’ particles while they are in motion. Diffusers release breath-like particles (1.0 micron in size) called tracers and our sensors collect tracers as they move through the physical site in aerosol particles. Particle data is then used for real-time air monitoring reporting key indoor air quality Metrics. Deployed throughout a building, diffusers and sensors under software control generate particles and measure them to calculate eACH for each room, identify transmission pathways, pathogen and pollution hotspots, and clearance rates delivering a compelling ROI for a healthy, energy-efficient building. Piera’s technology also delivers Air Quality Index metrics (AQI), alerts to pollution hot-spots, and classifies likely sources of pollution. The system analyzes the movement over time to produce data about how indoor air transports particles and bioaerosols.
Once the initial model of the building is determined it can be used to manage the building. As the building air changes due to occupancy, use, temperature, humidity, outdoor and indoor pollution, real-time continuous monitoring of particle data ensures clean air by knowing the exact density of the problematic sub-micron (and larger) sized particles that must be diluted and/or filtered. Simply put, the higher the number of particles, the more air filtering and fresh air intake is required to dilute and cleanse /filter the particles. In addition, the ability to classify pollutant sources (vape, smoke, cooking, aerosols) can be used to eliminate sources.
HVAC systems were designed for energy efficient comfort control, primarily relating to temperature and humidity levels. These systems were not designed for air purification and are insufficient. Upgrading to MERV 13 filters (If the system can handle the pressure drop) only captures a small portion of the sub-micron sized (dangerous) respiratory droplets that are floating in the air and may contain viruses. Even other floating particles potentially become “transport vehicles” for these lightweight infections’ droplets to “hitch a ride”. So, increasing air flow (purging) WITHOUT addressing the enhanced filtering of the air content may simply be facilitating the movement of these floating aerosols between all spaces in the building which share a common air supply. Virus-spreading risks may not be getting mitigated despite well-meaning “HVAC system upgrade” intentions.
In summary, the 3 ‘pillars’ of achieving healthy and energy efficient spaces are Monitor, Inform, and Mitigate in a continuous real-time loop. Piera Systems’ sensor technology enables the delivery of the 3 key indoor air quality metrics; eACH, EOA, and the EPA AQI along with particle data and alerts that can integrate with your existing Building Management Systems and a wide range of air cleaning products.
