Field Monitoring of New Homes

HENGH Team member installing a monitor in the bathroom.

Lawrence Berkeley National Laboratory (LBNL) is conducting an in-home monitoring study to measure the performance of mechanical ventilation equipment and indoor air quality in new California homes with gas appliances. This study involves setting up air quality and ventilation monitoring devices that will remain in place for a one-week period.

This study aims to recruit 70 homes to participate in the in-home monitoring. Homes to be included in the study will have the follow key characteristics:

  • Single-family detached house in California,
  • Built in 2011 or later,
  • Has gas appliances AND mechanical ventilation.

FAQ

What will happen during the in-home monitoring period?

Over a one-week period, we will make air quality measurements inside and outside of your home. In addition, field technicians will perform diagnostic tests to measure the performance of your mechanical ventilation equipment. We ask that you keep windows closed during the one-week period.

When will the in-home monitoring be scheduled?

Our study started in Summer 2016 and will continue until Spring 2018. A research team representative will contact you approximately two to four weeks prior to scheduling the in-home visit to find a date and time that works for you.

Who funded this research?

This research is funded by the California Energy Commission.

Who are the field technicians performing the work?

We are partnering with Gas Technology Institute (GTI) and California utility partners, Southern California Gas Company (SoCalGas) and Pacific Gas & Electric (PG&E), for this study. The in-home visits will be coordinated by GTI. Field technicians from GTI and gas utilities will be conducting the in-home monitoring.

How will my information be used?

The data you provided will help inform California's building energy codes on how to achieve adequate ventilation and good indoor air quality, while reducing air infiltration and the associated energy use.

Will my information be kept secured?

The data you provided will be encrypted and password protected. Study results will be used for research purposes only.

Who will have access to study results?

Aside from the research team, coded data (i.e. identifiable information removed, including names, street address, email, and phone numbers) will be shared with other researchers who are conducting studies in related areas.

How do I find out results from this study?

You will receive a report summarizing test results for your home. We plan to publish our analysis of the study results in 2018 after the completion of this study. A copy of our report can be accessed from this website.

What do I get from participating in this study?

Study participants will receive up to $350 in Lowe's gift card for completing the one-week sampling. You will receive a free safety inspection of your natural gas appliances. In addition, you will learn about indoor air quality in your home, as well as the performance of your mechanical ventilation equipment.
