Johnson Controls has produced a module for removing molecular contaminants from indoor air. Called YORK EcoAdvance, it manages the flow of outside air into a building at the same time.

According to Johnson Controls, the process reduces heating, ventilation and air conditioning (HVAC) peak loads by more than 40%, resulting in an average of 20–40% annual energy cost savings.

The YORK EcoAdvance module.The YORK EcoAdvance module.The system, which is based on HVAC Load Reduction (HLR) technology, is installed in conjunction with air handling units (AHUs), energy recovery ventilators, or rooftop units. It achieves the savings by minimizing the amount of outside air necessary to maintain air quality, while meeting and exceeding the requirements of ASHRAE Standard 62.1: Ventilation for Indoor Air Quality (IAQ).

The module’s self-cleaning operation automatically removes contaminants such as CO2, VOCs, and formaldehyde, from the building via the exhaust and uses smart sensors to continuously monitor system performance and air quality.

While higher energy efficiency HVAC systems typically require a larger investment, this system reduces the cost of required HVAC equipment. This system can also help buildings achieve US Green building Council Leadership in Energy and Environmental Design (LEED).

EcoAdvance includes networking connectivity to continuously control, record, and report all aspects of the system operation. IAQ can be monitored and the system remotely configured and controlled using a computer, tablet, or smart phone.

It is also compatible with BACnet for integration with building automation systems. The system is suitable for both new construction and retrofit applications. It is scalable by installing multiple modules.
