19-0117 v3.x - AWAIR Alternative to IAQ Test
We would like to propose an alternative compliance option for single family homes that pursue the healthy interior environment imperative. The Petal Handbook requires the results from indoor air quality (IAQ) tests before and nine months after occupancy. After discussing the testing requirements with several professionals in both Spain and United Kingdom, the lowest cost for performing these tests is 4.000 €. Since tests have to be performed twice, this would result in a cost of 8.000 €. We believe this is a disproportionate cost in order to demonstrate good indoor air quality. To meet the intent of the imperative, improve occupant health by reducing or eliminating indoor pollutants, we would like to propose the following alternatives for a single family home that does not exceed 380 m2.
We researched affordable monitoring equipment available and found a home indoor air quality monitoring equipment called AWAIR https://getawair.com/
This device allows for a continuous monitoring of Indoor Air Quality and measures the following:
• PM10 and PM2.5
The home which is pursuing the LBC certification is located in transect L6 and is located near a natural reserve where there is no urban pollution.The home does not have any carpets and all materials installed in the home meet the VOC requirements. By measuring the above values over time we believe this device is capable of demonstrating a good Indoor Air Quality.
Instead of measuring some specific VOCs, the device measures TVOCs.
Instead of measuring formaldehyde and 4-Phenylcyclohexane separately, they are measured as part of TVOCs. Treating VOCs as a group for this type of project is simpler and more effective. The EPA's Technical Assistance Document for Sampling and Analysis of Ozone Precursors lists more than 90 target VOCs that have potentially negative health effects while their Substance Registry Service lists over 230 VOCs. Also, VOCs tend to co-occur, meaning that if some of the VOCs in the above list are present, others coming from the same sources are likely present as well.
Carbon monoxide is not measured but Carbon monoxide monitors are installed on each floor in the house.
Since VOCs occur as a group and can often be treated as a group, measuring and reporting each chemical individually is impractical. Measuring and dealing with them as a group is simpler and far more effective. Ozone is, given the remote location. Finally, no diesel or gasoline fueled engines have been used during the construction process and therefore NO2 contamination is also not present.
The AWAIR device is available for 179 USD and is therefore an affordable alternative to demonstrate good Indoor Air Quality for a single family home located in a remote area where there is absence of urban traffic related pollution. In addition, it provides a continuous monitoring that can be read from the AWAIR App on a mobile phone.
The IAQ testing must demonstrate that the maximum allowable chemical concentrations are not exceeded. The AWAIR device alone, does not demonstrate compliance with the Healthy Interior Environment Imperative, and because there is no tracking over time or third party monitoring, there is no means to verify the project met air quality thresholds during the performance period.
