Energy Efficient Ventilation Effectiveness and Thermal Comfort
Displacement ventilation provides low velocity air at around 65°F that relies on buoyancy forces to drive the air motion. Supply air spreads across the floor until encountering thermal plumes from heat sources that naturally drive the clean, conditioned air up through the breathing zone. Heat and contaminants are carried up to high-level return or exhaust grilles instead of getting recycled through the space. The result is high ventilation effectiveness and improved thermal comfort delivered in an energy efficient manner.

Perimeter offerings that provide flexibility and efficiency
The future of commercial office design faces a number of challenges, including a shift away from densely occupied open office concepts and a heightened concern for occupant health. North America continues to adopt newer energy codes that task design firms to further reduce energy consumption. In addition, indoor air quality (IAQ) has arguably become a principal element of building design.
Although several air distribution systems can be designed to succeed at both of these elements, underfloor air distribution (UFAD) offers significant flexibility and IAQ improvements over traditional air distribution approaches. While the interior zone design has changed little over the years, the perimeter offering has evolved significantly.

Using Particle Tracking to Optimize Indoor Air Quality
During the COVID-19 pandemic, we’ve seen an increased focus on indoor air quality – especially regarding the spread of infectious diseases in all types of indoor environments. Since one path of transmission is through exhaled droplets both large and small, the engineering community is particularly interested in how those particles move in indoor environments.
