Mechanical ventilation and indoor air quality in recently constructed homes in cool and humid climates of the U.S.

This dataset was collected as part of the Building America Ventilation and Indoor Air Quality (BAVIAQ) field study. The BAVIAQ study aimed to measure indoor air quality (IAQ) parameters, characterize ventilation equipment and other house and household characteristics, and actions that impact IAQ, with a focus on the role of whole-house mechanical ventilation (WHMV). This dataset was obtained from visits and monitoring in 32 single-family homes constructed since 2013 in the cool and humid climate of Illinois. A total of 41 weeks of data were collected. These included one week of data collection in each home under the “as-found” condition of no WHMV, and a second week of data collection in nine homes, during which an exhaust fan was operated to provide WHMV. The dataset includes time-resolved measurements of CO2, PM2.5, formaldehyde, and radon at one or multiple indoor locations, and time-integrated samples of gravimetric PM2.5, NO2, NOx, and formaldehyde collected both indoors and outdo..., Overview of the data collection
The basic structure of the study was to characterize the mechanical ventilation equipment functionality in each house through observations and performance measurements, monitor ventilation equipment usage, and measure air quality parameters indoors and outdoors over weeklong periods. Data were also collected by asking occupants to provide information about the household, their practices related to ventilation and pollutant sources and controls, and their satisfaction with air quality, thermal comfort, and other environmental factors in the home. Homes were monitored for one week with their WHMV operating as-found. In a subset of homes, the WHMV was configured by the research team to meet the ASHRAE 62.2–2013 continuous ventilation requirement and monitored for a second week. Due to limitations in finding homes with operable WHMV, local exhaust fans were utilized to meet ASHRAE 62.2.
Each study home was visited by a two-person field team at the start and e..., # Data from: Mechanical ventilation and indoor air quality in recently constructed homes in cool and humid climates of the U.S.

## Description of the data and file structure

### What is in the dataset?

The dataset contains the most relevant information collected about the houses and household, their mechanical equipment, results of the participant survey, results of air leakage and airflow measurements at the homes, pollutant concentrations measured by time-integrated passive samplers inside and outside of the home, usage of cooktop and oven, external door and window open state, and time-series or air pollutants and environmental indicators measured within and outside of the houses.

## Files and variables

### Infiltration_Airflow

This folder (Infiltration_Airflow.zip) contains time-resolved data of the calculated natural infiltration airflow during the measured week for each test home. The natural inf..., This study was reviewed and approved by the Central Institutional Review Board (IRB) of the U.S. Department of Energy. All participants provided written informed consent, which included permission to publish their de-identified data in the public domain for research and educational use. To protect participant privacy, all personally identifiable information (PII)—including names, addresses, precise geolocation, and contact information—has been removed or anonymized. Each home was assigned a randomly generated study ID that does not correspond to any internal or field-collected identifier. Time stamps were generalized as needed to prevent potential re-identification, and no free-text responses or media content are included. The dataset has been reviewed to ensure that the risk of re-identification is minimal, in compliance with established data protection standards.​​

本数据集为美国建筑通风与室内空气质量（Building America Ventilation and Indoor Air Quality，BAVIAQ）实地研究的一部分。BAVIAQ研究旨在测量室内空气质量（indoor air quality，IAQ）参数，刻画通风设备及其他住宅与家庭特征，以及影响IAQ的行为，重点关注全屋机械通风（whole-house mechanical ventilation，WHMV）的作用。本数据集来源于2013年以来在伊利诺伊州凉爽湿润气候区建造的32栋独栋住宅的走访与监测，共收集41周数据。其中包括每栋住宅在无WHMV的“现状”条件下一周的数据采集，以及9栋住宅在运行排风扇提供WHMV时的第二周数据采集。

数据采集概述
本研究的基本框架为：通过观察与性能测试刻画每栋住宅的机械通风设备功能，监测通风设备使用情况，并在一周周期内测量室内外空气质量参数。同时，通过住户调查收集家庭信息、通风与污染源及控制措施的实践，以及对住宅空气质量、热舒适度及其他环境因素的满意度数据。住宅在WHMV“现状”运行状态下监测一周；在部分住宅中，研究团队将WHMV配置为满足ASHRAE 62.2–2013连续通风要求并进行第二周监测。因难以找到配备可运行WHMV的住宅，研究采用局部排风扇以满足ASHRAE 62.2标准。

每栋研究住宅由两人实地团队在研究开始与结束时走访...
