Sustainable Net Zero Home Uses Sensor to Detect Volatile Organic Compounds, Ventilate for Optimal IAQ

When VOCs are minimized, the module instructs the system to decrease ventilation, thereby improving energy efficiency and lowering utility costs.

AppliedSensor, a designer and manufacturer of chemical sensor components, announced today that its iAQ-100 intelligent Indoor Air Quality Module is installed in Newell Instruments’ Equinox House. The “net zero residence” is known for its ability to consume the same amount of energy as it produces, and was featured in a recent ASHRAE Journal article series. The iAQ-100 is incorporated into the home’s Conditioning Energy Recovery Ventilator (CERV) to detect and remove a broad range of potentially harmful volatile organic compounds (VOCs). When VOCs are minimized, the module instructs the system to decrease ventilation, thereby improving energy efficiency and lowering utility costs. Data gathered by Newell Instruments shows a consistent correlation of VOC-to-CO2 levels. In addition, overall results indicate optimal indoor air quality and quick recovery from episodes involving higher levels of VOCs.

“My wife and I have lived comfortably in Equinox House for the past year, and the iAQ-100 has proven to be a very accurate and cost-effective VOC sensor. The installation has certainly helped Newell Instruments understand how human activity correlates with CO2 and VOC levels – and how to implement these findings with a demand-controlled ventilation algorithm,” said Newell Instruments Vice President Ty Newell.

ASHRAE – international technical society organized to advance the arts and sciences of heating, ventilation, air-conditioning and refrigeration – publishes ASHRAE Standard 62.2 for residential ventilation specifying that healthy indoor air quality translates to minimal odors and CO2 levels. Due to Equinox House’s energy-efficient structure and furnishings, all VOCs in the home are emitted from humans. When the home is unoccupied, human-generated VOCs evaporate or dissipate within a day, leaving indoor air at a quality level comparable to fresh outdoor air.

“While the iAQ-100 has successfully monitored IAQ in several commercial facilities, this is the first time it’s been installed in a sustainable, solar home. The entire Equinox House is extremely innovative and we’re honored that our equally innovative gas sensor technology contributed to the home’s energy-efficient capabilities,” said AppliedSensor, Inc. CEO Tom Aiken.

The Equinox House is powered by a grid-tied solar photovoltaic array designed to supply 100% of its annual energy requirements. To detect VOCs, the iAQ-100 uses micro-machined metal oxide semiconductor (MOS) technology based on changes in resistance of a sensitive metal oxide layer induced by the surface interaction with ambient gases.
