All the living microorganisms inside an indoor environment, and their byproducts, are known collectively as an indoor microbiome. On this page, you will find answers to questions like "What is a normal indoor microbiome?" and "Where do microorganisms in the indoor environment come from?" As we continue to learn more about the indoor microbiome and how it can impact occupant health, this new resource gives an overview of our current understanding. The webpage provides links to EPA-sponsored microbiome reports from NASEM and includes information on actions that can be taken to maintain a generally healthy indoor environment. IAQ Emergency Preparedness, Response and Recovery Weather-related and man-made emergencies and disasters can damage homes and buildings and make the air indoors unhealthy to breathe. With climate change, weather-related emergencies are becoming more frequent and more severe. EPA's updated Emergencies and IAQ webpage provides tips on how to prepare for, respond to and recover from weather-related and man-made emergencies and disasters that affect indoor environments, including wildfires, power outages, hurricanes and flooding, and more. IED recently posted a video on Wildfire Smoke and Indoor Air Quality: How to Set Up a Clean Room at Home. A clean room is a room that is set up to keep levels of smoke and other harmful particles as low as possible during wildfire smoke events. Household Energy (Cooking, Heating and Lighting in Low- to Middle-Income Countries) President Recommits Work with Clean Cooking Alliance During the Climate Leaders' Summit In April, President Biden committed to rejoin the Paris Agreement and took executive action to tackle the climate crisis in the United States and other countries. In coordination with the President's action, Administrator Michael Regan also announced that EPA will resume and strengthen our commitment to the United Nations Foundation's Clean Cooking Alliance and will work with the Alliance, other country governments and partners at every level to reduce emissions from home cooking and heating that contribute to climate change and affects the health and livelihoods of almost 40 percent of the world's population. At the 26th meeting of the Council of Parties (COP26), which will be held in Glasgow, Scotland, in November 2021, the Administration will announce a whole-of-U.S.-government approach to address this challenge. This announcement is expected to include commitments by numerous agencies (Agency for International Development, CDC, DOE, EPA and National Institutes of Health) on what actions they will be taking in the coming years. Promotion of ISO Stgndgrds The household energy community has completed and issued important standards in the past two years through the International Organization for Standardization (ISO) process. In 2018, ISO published the international standard for laboratory testing of cookstoves, which includes protocols to test and report www.epa.goy/indoor~air~quality-iaq/federaHnterageney-eoromittee~indoor~air~qualitv Disclaimer: The opinions expressed by private persons during the public proceedings of the Federal Interagency Committee on Indoor Air Quality (CIAQ) are solely those of the speakers.

The new standards serve as the basis for national policies and programs on cookstoves, while also incentivizing manufacturers and developers to improve stove quality and performance. In 2019, a second ISO household energy standard was finalized, "Guidance on Field Testing Methods for Cookstoves," which provides a framework for organizations, countries and regions to adapt and implement cookstove protocols, metrics and targets based on their priorities over the coming months and years. EPA is now working with the Clean Cooking Alliance, ISO, the World Health Organization, and the Dutch and German development agencies to organize and facilitate regional workshops to promote the adoption or the adaptation by countries of the recently finalized ISO harmonized laboratory standards for clean cookstoves and clean cooking practices. Last month, EPA, in partnership with the Clean Cooking Alliance, ISO, World Health Organization, Pan American Health Organization and the Berkeley Air Monitoring Group, launched the first in a series of virtual sessions to support the adoption or adaptation, and implementation, of national standards for cookstoves in Latin American countries. More than 125 stakeholders from the Ministries of Energy, Environment, and Health; national standards bodies; as well as other implementation partners from 12 countries (Bolivia, Brazil, Chile, Columbia, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay and Peru) are participating. This workshop series is the fourth in a series of regional standards dissemination workshops, following an Asian regional workshop held in Nepal (December 2018), an East African/Anglophone regional workshop held in Uganda (July 2019), and a virtual workshop for Francophone African countries and Haiti (October 2020 to March 2021). Advancing Sustainable Household Energy Solutions (ASHES) Initiative at Colorado State University An EPA cooperative agreement recipient, Colorado State University, in collaboration with Berkeley Air Monitoring Group, began a new household energy solutions and air quality initiative. Through the Advancing Sustainable Household Energy Solutions (ASHES) initiative, Colorado State is building a consortium of household energy community members that includes researchers, academics, practitioners, private industry and community partners working together to define the way forward and advance sustainable household energy solutions for public health and environmental sustainability. This work includes a webinar series that focuses on disseminating the latest on household energy.

The NRAP expands the efforts under the Federal Radon Action Plan to focus on actions that go beyond federal governmental actions alone. The NRAP presents a long-range strategy for eliminating avoidable radon-induced lung cancer in the United States. The Plan's near-term goals are to reduce radon risk in 5 million homes and to save 3,200 lives. While these goals offer bold and important milestones, the NRAP's ultimate goal is to eliminate avoidable radon-induced lung cancer in the United States by incorporating radon testing, radon mitigation and radon-resistant construction into the systems that govern purchasing, financing, constructing and renovating homes and other buildings. Progress for NRAP strategies can be tracked at www.radonleaders.org/resources/nationalradonactionplan. NRAP Leadership is currently reviewing and finalizing a new Action Plan that will cover the period from 2021-2025. We at EPA deeply appreciate the involvement of the American Association of Radon Scientists and Technologists (AARST), Conference of Radiation Control Program Directors (CRCPD), our colleagues at HUD and CDC, as well as NGOs as we come together to identify the most important work over the next few years to save lives from radon-induced lung cancer. Several themes have emerged in discussions for the next version of the NRAP, including— • A commitment to changing building codes, as well as a focus on tenant resources and action. • Leveraging available sources of funding and recognizing opportunities to seek additional funding. • And finally, a commitment to address disparities in radon risk reduction. State Indoor Radon Grants (SIRG) This Administration requested an increase of $1 million (M) in the fiscal year (FY) 2022 budget for state and tribal radon grants (the FY 2021 SIRG funding was appropriated at $7,795 M). EPA will need to wait for Congressional appropriations to confirm the requested increase is enacted, but the Agency is hopeful that it will be, and IED has begun engaging our regional offices to consider options for how to implement the increase in SIRG funding. Tribal Performance Partnership Grants Performance Partnership Grants (PPGs) will become more accessible to tribes. PPGs allow grantees to combine funds from multiple environmental program grants into a single grant with a single budget and allows grantees to direct resources to where they are needed most to address their environmental and public health priorities. By including radon in a PPG, a tribe could eliminate the high match requirement for radon grants and overcome the significant hurdle that the high grant match requirement has created for tribes. IED is hopeful this action will create a pathway for additional tribes to successfully apply for and receive radon grant funds and provide some relief for existing tribal radon grant recipients.

Building Codes EPA continues to collaborate with industry and states to actively engage in efforts to promote adoption of radon-resistant new construction (RRNC) practices through international, national, state and local building codes. These efforts are mandated by the Indoor Radon Abatement Act and also are a key component of the NRAP. EPA is working with key radon stakeholders to draft code changes or introduce new code requirements in several different areas within the broad spectrum of the International Code Council (ICC) portfolio, which includes— • International Building Code o Educational Occupancies Requirement (schools and daycares) o Multifamily Buildings Requirement (R-2: apartment houses, congregate living facilities, etc.) o A non-mandatory provision for radon control in the body of the code o A new appendix—available for adoption by local and state jurisdictions • Property Maintenance Code o A testing and mitigation requirement The proposals for the various changes/additions to the ICC codes were submitted in January 2021 and then presented/defended at the Committee Action Hearings (CAH). While all proposals were voted down (disapproved), support was shown by some members of the voting board. EPA collaborated with radon stakeholders and provided comments during the public comment period on the Committee's ruling taking into account feedback from the CAH and simplifying language to make it more enforceable. Radon Credentialing EPA's work on radon credentialing is part of the Agency's responsibility to promote and support the availability of quality radon services to the public. Professionals who provide radon testing and mitigation services play a key role in public health protection efforts. Because of the substantial risk resulting from exposure to radon, it is critical for radon service providers to possess the necessary skills to provide quality services and ensure consumer protection. Over the last several years, EPA has been working, through consultation with states, the public and industry—and in response to Congressional direction—to develop a contemporary framework to guide the credentialing of radon service providers going forward. EPA remains committed to facilitating access to a qualified workforce through a national, nonregulatory framework that will help establish a quality standard for state-run and independent programs that credential radon service providers.

Comprehensive IAQ Interventions in Schools Indoor Air Quality. Healthy Green Cleaning, and Preventive Maintenance in Schools As a result of the COVID-19 pandemic, EPA's Schools Program has pivoted to focus work on increased interest in healthy indoor environments in schools, increased urgency to respond to IAQ issues in schools, and leveraging key partnerships to expand our network of stakeholders. EPA developed a new infographic, Proven Strategies to Improve Indoor Air Quality in Schools, in response to requests from stakeholders for more information about proven strategies to reduce pollutants in the air and limit the spread of viruses and bacteria in schools. The infographic outlines key actions for providing healthy air to students and staff, such as (1) increasing ventilation rate, (2) increasing HVAC filter efficiency, and (3) supplementing with portable air cleaners. Schools should maximize ventilation rates to the extent possible by bringing in as much outdoor air as weather and outdoor air quality permit. When sufficient HVAC adjustments are not possible, consider other means of bringing in outdoor air and using portable air cleaners as a supplemental filtration strategy. EPA released updated web content on schools and COVID-19.

This site (https://betterbuildingssolutioncenter.energy.gov/covidl9) includes fact sheets developed by the national laboratories for the hospitality, office, retail and grocery sectors. As part of this effort, DOE hosted a webinar on July 19, 2021, "Office Buildings and Ventilation: How COVID-19 and Other Pathogens Spread Between Zones," which is saved here: https://betterbuildingssolutioncenter.energv.gov/webinars/office-buildings-and-ventilation-how-covid- 19-and-other-pathogens-spread-between-zones. DOE's Weatherization and Intergovernmental Assistance Program has two studies in progress. Multifamilv Building Ventilation Study The purpose of this pilot study is to characterize the impact that weatherization and feasible ventilation improvements have on the indoor air quality of large, centrally ventilated multifamily buildings as currently performed under the Weatherization Assistance Program (WAP) in the State of New York under their variance request (i.e., to implement ASHRAE Standard 62.2-2016 "to the greatest extent possible" in this type of multifamily building). A major goal is to determine if these practices improve or at least "do no harm to" the indoor air quality of the weatherized multifamily buildings. DOE is reviewing the initial report. Upstate New York has three remaining dwellings that require post-weatherization data collection in 2022. The final report will be submitted to DOE in June 2022. Vermiculite Study A field study is measuring indoor asbestos levels in homes with existing vermiculite insulation before and after blower door tests are conducted and/or insulation is installed. Worker exposures also will be measured. The study results will be used by DOE to develop additional guidance on strategies to address asbestos contamination in vermiculite insulation and how to better approach the weatherization of homes with existing vermiculite insulation, including precautions needed, and avoidance criteria. Remaining timeline: • Data collection (until December 2022) • Sample analysis (by June 2023) • Final report (by September 2023) www.epa.goy/indoor~air~quality-iaq/federaHnterageney-eoromittee~indoor~air~qualitv Disclaimer: The opinions expressed by private persons during the public proceedings of the Federal Interagency Committee on Indoor Air Quality (CIAQ) are solely those of the speakers.

Working with Wisconsin Focus on Energy (WIFOE), DOE has a healthy homes pilot study that aims to determine any noticeable effect of work carried out by WIFOE or its contractors on the indoor air quality of each home worked on—on a case-by-case or aggregated basis. WIFOE has an interest in the impact of retrofit activity on the indoor environment and the relationship between the indoor environment and asthma occurrence or relief. There are at least 50 sites, and results are expected in mid-2022. Air is collected at each home for at least one week before and one week after retrofit activity is carried out. The data collected are C02 concentration, PM2.5 concentration, temperature and relative humidity. Lawrence Berkeley National Laboratory and DOE launched the Efficient and Healthy Schools campaign, which aims to engage K-12 schools to improve energy performance and indoor air quality, with a focus on practical solutions involving HVAC and other technologies to reduce energy use and carbon emissions. With technical support from Lawrence Berkeley National Laboratory, the campaign was developed with contributions from ED and EPA. Participants and supporters will receive our campaign newsletter on best practices and case studies. Participating schools can also engage in peer-to-peer learning, receive recognition, and contribute to the development of technical resources to HVAC solutions that improve energy performance and indoor air quality. Supporters can partner with the campaign team to promote improvements in K-12 schools and share the benefits of efficient and healthy school buildings. See https://efficienthealthyschools.lbl.gov. Lawrence Berkeley National Laboratory gave presentations about continuing research projects. Ventilation and Indoor Air Quality in New U.S. Homes: Preliminary Observations from a Building America Field Study The presentation Ventilation and Indoor Air Quality in New U.S. Homes: Preliminary Observations from a Building America Field Study was given at the Energy & Environmental Building Alliance's High Performance Home Summit in Denver, CO, which was held September 14-16, 2021. The presentation was about DOE's National New Home IAQ Study, which seeks to characterize IAQ and factors that impact IAQ in new homes built to current codes, including those with and without mechanical ventilation. The study addresses the following issues: • The necessity and value of mechanical ventilation. • Whether ventilation alone is sufficient to maintain IAQ. • Limited data on installed performance. • Equipment not performing to their specifications. www.epa.goy/indoor~air~quality-iaq/federaHnterageney-eoromittee~indoor~air~qualitv Disclaimer: The opinions expressed by private persons during the public proceedings of the Federal Interagency Committee on Indoor Air Quality (CIAQ) are solely those of the speakers.

All three of our agencies have received many questions about the safety of such mechanisms for dispersing pesticides and disinfectants. This coordinated approach and co-branding of a single infographic reduces duplication of efforts across agencies and simplifies messages for building managers and occupants who might be exposed to chemicals through these methods. CDC worked closely with a graphic artist to develop images that conveyed complex concepts of PPE used when applying the product via fogging or misting. The graphic was approved by all three agencies, and it is now posted on the HUD website. We are awaiting final approval to place on the CDC website. Division of Environmental Health Science and Practice Asthma and Community Health Branch The branch continues to disseminate messages regarding indoor carbon monoxide poisoning and mold exposure in Louisiana and the Gulf region in the aftermath of Hurricane Ida and other recent storms. They recently posted a new fact sheet on reducing exposure to mold indoors. Water. Food and Environmental Health Services Branch This branch continues to promote their Building Reopening website. Several jurisdictions are reporting increases in Legionnaires' disease. • Stagnant or standing water in a plumbing system due to building closures or decreases in occupancy can increase the risk for growth and spread of Legionella. • CDC has steps to minimize risk when reopening buildings, such as flushing water systems. • CDC reminds cooling tower operators of the importance of following best practice operation and maintenance guidance, including start-up and shutdown procedures. New publication on racial disparities in incidence of Legionnaires' disease that cites air quality as a factor in Legionnaires' disease exposure: Hunter CM, Salandy SW, Smith JC, Edens C, Hubbard B. Racial Disparities in Incidence of Legionnaires' Disease and Social Determinants of Health: A Narrative Review. Public Health Rep. 2021. In summary, certain housing and facility conditions may create environments conducive to Legionella growth. For example, an examination of Legionella samples in a Legionnaires' disease patient's home, workplace and hotel found that the workplace was the most likely source of exposure. www.epa.goy/indoor~air~quality-iaq/federaHnterageney-eoromittee~indoor~air~qualitv Disclaimer: The opinions expressed by private persons during the public proceedings of the Federal Interagency Committee on Indoor Air Quality (CIAQ) are solely those of the speakers.

Certain molds, including Aspergillus species, mucormycetes and Fusarium species, can cause serious, invasive infections in hospitalized patients. Numerous health care-associated outbreaks have been traced to airborne mold exposures. In a survey of hospital epidemiologists, most respondents reported that their hospitals performed air sampling but that techniques and interpretations varied widely. MDB staff would be interested in hearing from federal partners with an interest and expertise in the topic. National Institute for Occupational Safety and Health (NIOSH) Respiratory Health Division Field Studies Branch The branch recently published a paper on particle and gas emissions from recycling plastic and using the material for 3D printing. An international collaborative study of characterizing mixed exposures in school classrooms are being conducted in South Korea. Air, elevated surface dust, floor dust, and air conditioner filter dust samples have been collected from 18 classrooms in six schools out of a total of 12 schools aimed. The samples will be analyzed for bacterial and fungal DNAs, endotoxin, and ergosterol to examine classroom microbiome and the associations of the microbiomes among different types of samples within classroom. Additionally, Korean collaborators are analyzing classroom PM and the chemical composition of PM. Thus, the association between microbial community and chemical composition in PM will also be examined. Health Effect Laboratory Division Allergy and Clinical Immunology Branch In August 2021, the NIOSH Report on the "Toxicity Studies of Stachybotrys chartarum (CAS No. Stachybotrys) in B6C3F1/N Mice Exposed by Inhalation" was completed and sent to the National Toxicology Program (NTP). In addition, NTP Study #C15017—"Evaluation of the Sub-chronic Toxicity of Aspergillus versicolor" was completed in early October, and once the data has been collected, a report will be drafted and sent to the NTP in 2022. www.epa.goy/indoor~air~quality-iaq/federaHnterageney-eoromittee~indoor~air~qualitv Disclaimer: The opinions expressed by private persons during the public proceedings of the Federal Interagency Committee on Indoor Air Quality (CIAQ) are solely those of the speakers.

Technical Studies and Healthy Homes/Weatherization Demonstration Grant Awards On October 13, 2021, HUD announced the award of approximately $15.7 M to 18 universities, public health, and housing organizations to conduct housing-related hazard and energy-efficiency research studies. The research grants aim to identify and improve methods for detecting and controlling lead and other housing-related health and safety hazards and will incorporate weatherization into residential lead and healthy homes interventions. Approximately $6.6 M was awarded under the HHTS Grant Program to seven institutions/research organizations (see abstracts below), approximately $4.1 M was awarded under the Lead Technical Studies Grant Program to six institutions/research organizations, and $5 M was awarded under the Healthy Homes and Weatherization Cooperation Demonstration Grant Program to public health and housing organizations/agencies (see abstracts below). HHTS Grant Program Awards The University of Tulsa: This study proposes to further develop the mold classification tool (MCT)— which is a DNA-based, machine learning approach for classifying the dampness/mold (D/M) status of a building based on the fungal ecology of settled dust samples—into a broadly applicable tool for home mold inspection and assessment of remediation effectiveness. The study has two objectives: (1) determine if the MCT accurately tracks the return of a home's fungal ecology from water- damaged/moldy (D/M) to normal after thorough, standardized D/M remediation has been conducted and explore associations between MCT scores with quantitative metrics of observable D/M previously correlated with health; and (2) collect pilot data for planning a future study linking successful mold remediation (assessed by MCT) and improved health among asthmatic children. The proposed study will be a longitudinal environmental intervention study of thorough D/M remediation in 50 homes with moderate to severe D/M and incorporates a 20-home control group without D/M.

Julien, rhona.p. julien@hud.gov Duke University: This project will evaluate new approaches to quantify and reduce chemical exposures from common building materials, with an emphasis on plastic additives, pesticides, flame retardants and lead. The objective of this project is to develop methods to quantify and reduce chemical exposures from the home environment using approaches that are adaptable and customizable to individuals and households. The study will use a three-tier approach to achieve this goal: (1) advance a new wearable passive sampling device to enable quantification of personal exposures to both metals and organic compounds, (2) identify the types of building materials and housing characteristics associated with higher levels of exposure to different classes of contaminants, and (3) assess the effectiveness of a simple robotic vacuuming intervention for reducing exposure to a range of indoor contaminants that pose health risks. Principal Investigator: Heileen Hsu-Kim, Ph.D., hsukim@duke.edu HUD Contact: Rhona P. Julien, rhona.p. julien@hud.gov National Center for Healthy Housing: The proposed study will test the premise that Passive House multifamily design in affordable housing offers two elements that should result in lower PM2.5 levels in these homes compared to those in conventionally built multifamily homes: (1) a very tight building envelope that will reduce infiltration of outdoor PM2.5 and (2) the use of a continuously running balanced energy recovery ventilator (ERV) with a high-efficiency filter to reduce indoor- and outdoor- generated PM2.5. The primary design will be a two-group comparison study. The first group will be recently constructed multifamily affordable housing built to Passive House standards. These buildings will have a tight building envelope and a balanced ERV that provides adequate air exchange for residents. In addition, the ERV will be fitted with a MERV 13 or higher filter on the supply side of the ventilation system to remove PM in the fresh air entering the dwelling. The second group will be recently constructed multifamily affordable housing that is built to conventional energy-efficiency standards (the International Energy Conservation Code as adopted by Massachusetts). These buildings will have exhaust-only ventilation system using bath fans to provide whole-house ventilation, a common ventilation system for this building design. This second group will serve as controls for the study. The study will compare the levels of PM2.5, C02, relative humidity and indoor temperature between the two groups.

Contact: Dustin Poppendieck, dustin.DODDendieck@nist.gov Fate and Transport of Indoor Microbiological Aerosols (FaTIMA) In response to the COVID-19 pandemic, NIST developed an online tool to enable users to consider the effects of several factors on transmission of and exposure to airborne, virus-containing aerosols. These factors include aerosol size, emission rates and variations in these rates, deposition rates (for walls, floors, ceilings and other surfaces), pathogen inactivation rate, ventilation and filtration. The tool implements a web-based version of the CONTAM simulation engine to simulate a single, well-mixed zone for a 24-hour period. Inputs enable the definition of a source—for example, infected individual(s)—to emit aerosols both continuously (breathing) and intermittently (coughing or sneezing). Room dimensions and ventilation system characteristics also are defined, including total supply, return and fraction of outdoor air flow rate. System filters and local exhaust and in-room air cleaners also can be included. An occupant is simulated in the room either continuously or intermittently over a user-defined occupancy period during the 24-hour simulation—for example, to simulate a caregiver intermittently checking on the infected occupant. The tool will calculate the airborne concentration, occupant exposure and surface loading over the 24-hour period and provide results both numerically and graphically. Transient charts show the time histories and integrated values for concentration and occupant exposure for the 24-hour period and the user-defined occupancy period. Summary charts provide relative percentages of aerosol fate (exited zone, filtered, deposited, deactivated and remain airborne), sources (continuous, intermittent and outdoors), deposition www.epa.goy/indoor~air~quality-iaq/federaHnterageney-eoromittee~indoor~air~qualitv Disclaimer: The opinions expressed by private persons during the public proceedings of the Federal Interagency Committee on Indoor Air Quality (CIAQ) are solely those of the speakers.

Stuart Dots, william.dols@nist.gov Single-Zone Simulations Using FaTIMAfor Reducing Aerosol Exposure in Educational Spaces FaTIMA was applied to a classroom, portable classroom and assembly room. NIST evaluated the relative effectiveness of various measures to reduce exposure to infectious aerosols, including masks, increasing ventilation, increasing filtration, using portable air cleaners and using exhaust fans. Multiple controls can be implemented in spaces and HVAC systems to reduce exposure as part of a broader risk reduction strategy that might be pursued by a building owner or manager. As noted by ASHRAE, engineering and other controls should be part of a larger, layered risk reduction strategy that includes hand washing, surface cleaning, social distancing and reduced occupant density.

The research, knowledge and standards development activities across environmental microbiology, building science and engineering, transmission, and social sciences also were discussed. A summary of the Summit can be found in a journal article, "Critical Capability Needs for Reduction of Transmission of SARS-CoV-2 Indoors," in Frontiers in Bioengineering and Biotechnology at https://www.frontiersin.org/articles/10.3389/fbioe.2021.641599/full. ASHRAE Standard 62.2 The committee responsible for Standard 62.2 on residential ventilation and IAQ met by webinar in May and June to continue working on proposed changes that may be included in the 2022 version of the standard. Topics being addressed include changes to poor ambient air quality, kitchen hood capture efficiency and unvented combustion appliances. The committee will meet again in January 2022. Contact: Steven Emmerich, steven.emmerich@nist.gov ASHRAE Standard 189.1 The 2020 version of ASHRAE/ICC/IESUSGBC SSPC 189.1, Standard for High-Performance Green Buildings Except Low-Rise Residential Buildings, has been published. The standard will constitute the technical content of the 2021 International Green Construction Code. In the area of indoor environmental quality, revisions that have been incorporated into the 2020 standard (and therefore the 2021 IgCC) include an update on the requirements for soil gas control and occupant access to views of the outdoors, as well as other changes. The 2020 standard also includes so-called "jurisdictional options" (JOs), which allow adopting jurisdictions to delete selected requirements of the standard if they so choose; the goal of these JOs is to increase adoption of the IgCC. The committee holds monthly web meetings, which are open to all interested parties. More information on the 189.1 committee activities can be found on the ASHRAE website, where you can sign up for notifications of public reviews and other information at https://www.ashrae.org/resources~~ publications/free-resources/listserves.

Contact: Lisa Ng, lisa.na@nist.gov ASHRAE Position Documents ASHRAE initiated a new Position Document on Indoor Carbon Dioxide, which is being drafted and is expected to be approved in early 2022. ASHRAE has also initiated efforts to revise its Position Documents on Infectious Aerosols and on Limiting Indoor Mold and Dampness in Buildings. Contact: Andrew Persily, andvp@nist.gov CO2 Monitoring Outreach The use of C02 monitoring in schools has increased in efforts to identify poorly ventilated classrooms across the country. The same also is true for many other occupied spaces. NIST has summarized the challenges and usefulness of this approach in two outreach webinars. On October 7, Dustin Poppendieck presented a webinar to the Collaborative on Health and the Environment (https://www.healthandenvironment.org/webinars/96581) on the uncertainty associated with using C02 for classroom ventilation evaluation. On October 29, Andrew Persily will give a talk on using C02 monitoring to manage ventilation in buildings as part of the International Society of Indoor Air Quality and Climate (ISIAQ) webinar series on managing buildings in the context of airborne disease transmission (https://mms.isiaq.Org//Calendar/moreinfo.php?eventid=65631). An extended webinar on the same topic is being sponsored by EPA in mid-November (date to be announced by EPA). ASHRAE Green Guide Version VI The sixth revision of the ASHRAE Green Guide is underway. Version VI will target more experienced building professionals, whereas the previous versions contained more introductory content. NIST is taking the lead editorial roles on the IEQ and Water Efficiency chapters.
