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.

Creating Comfort, Efficiency and Sustainability with VAV Diffusers
High performance air systems demand modern design approaches with leading-edge
products and technology in order to optimize comfort and reduce energy consumption. A
comfortable environment is achieved by providing the smallest possible zones of temperature
control, allowing for individual temperature distribution and better air movement. Reduction
in energy is realized by designing a low-pressure HVAC system that allows for maximum
turn-down while maintaining temperatures.
