High Performance Air Systems

AMCA believes that ducted air systems are an effective, energy-efficient and economical means for satisfying ventilation requirements in commercial HVAC systems. We advocate for the consideration of high performance air systems to help achieve the result you or your client need.

High performance air systems (HPAS) use a modern design approach with leading products and technology to optimize energy efficiency, comfort and indoor air quality.

HPAS design integrates the strategies of right-sizing, zone optimization and outside-air-based free cooling. HPAS systems also minimize static pressure, system leakage and system effects.

HPAS technologies include high efficiency fans, outside air economizers, low-leakage dampers and ducts, low-pressure-drop components, diagnostic sensors and digital controls.

The following are resources regarding high performance air systems:
