CONTAM is based on a graphic interface that allows the user to draw floor plans on a "sketchpad" and employ "icons" to represent airflow paths, ventilation system components, and contaminant sources. CONTAM has been used at NIST to study the indoor air quality impacts of HVAC systems in single-family residential buildings, ventilation in large mechanically-ventilated office buildings, and radon entry and transport in large residential, office, and school buildings.</p> <p>Measurement procedures are being developed and demonstrated to evaluate building ventilation and indoor pollutant concentrations. These procedures range from sophisticated tracer gas methods used predominantly in building research efforts to less involved procedures that can be employed by building operators. NIST researchers are continually developing new test procedures, and then demonstrating them in the field to evaluate their feasibility and reliability. The efforts in which these procedures are demonstrated in the field has resulted in the development of an important database of building ventilation and indoor air quality performance.</p> <h4><a href="https://web.archive.org/web/20231129195846/https://www.nist.gov/staff/group/6701">Staff Directory</a></h4> <p> </p> <div class="media-element-container migrated group-migrate-image"> <p><a href="https://web.archive.org/web/20231129195846/https://www.youtube.com/watch?v=jkO9PK4JvJI"><img alt="bfrl portable generator video" height="90" src="/web/20231129195846im_/https://www.nist.gov/sites/default/files/images/el/portablegeneratorvideo_1.jpg" title="bfrl portable generator video" width="120" loading="lazy"/></a></p> <div class="field field--image-caption"><a href="https://web.archive.org/web/20231129195846/https://www.youtube.com/watch?v=jkO9PK4JvJI">How Close isToo Close forPortable Generators?</a>(NIST YouTube channel)</div> <div class="field field--image-caption"> </div> </div></div> </div> <div class="paragraph paragraph--type--dynamic-content-list-ou paragraph--view-mode--default"> <div class="nist-block "> <h2 class="nist-block__title"> <div class="string">News and Updates</div> </h2> <div class="viewsreference"><div class="views-element-container"><div class="js-view-dom-id-b967006e52428349b910b864c5adba640c3553735609a2ede00a67bea6a78cdb"> <div> <article about="/news-events/news/2022/07/nists-indoor-co2-tool-can-help-assess-ventilation-and-indoor-air-quality" typeof="schema:Article" class="nist-teaser"> <div class="nist-teaser__image"> <div class="entity-reference"> <a href="/web/20231129195846/https://www.nist.gov/news-events/news/2022/07/nists-indoor-co2-tool-can-help-assess-ventilation-and-indoor-air-quality" hreflang="en"><img loading="lazy" src="/web/20231129195846im_/https://www.nist.gov/sites/default/files/styles/thumbnail/public/images/2022/05/31/Girts-Ragelis-SS_2044792412.jpg?itok=Kmsmz3Yo" width="100" height="67" alt="A white, square plastic CO2 meter sits on a table in a restaurant setting, reading 621 ppm." typeof="foaf:Image"/> </a> </div> </div> <div class="nist-teaser__content-wrapper"> <header> <h3 class="nist-teaser__title"><a href="/web/20231129195846/https://www.nist.gov/news-events/news/2022/07/nists-indoor-co2-tool-can-help-assess-ventilation-and-indoor-air-quality"><span property="schema:name">NIST’s Indoor CO<sub>2</sub> Tool Can Help Assess Ventilation and Indoor Air Quality</span> </a></h3> <div class="nist-teaser__date"> <div class="daterange"><time datetime="2022-07-19T12:00:00Z">July 19, 2022</time> </div> </div> </header> <div class="nist-teaser__content"> <div property="schema:text" class="text-with-summary"> The free tool calculates target CO2 levels based on the user’s desired ventilation rate and information about a building and its occupants. </div> </div> </div> </article> </div> <div> <article about="/news-events/news/2021/11/streamlined-nist-tool-could-help-homeowners-renters-reduce-airborne" typeof="schema:Article" class="nist-teaser"> <div class="nist-teaser__image"> <div class="entity-reference"> <a href="/web/20231129195846/https://www.nist.gov/news-events/news/2021/11/streamlined-nist-tool-could-help-homeowners-renters-reduce-airborne" hreflang="en"><img loading="lazy" src="/web/20231129195846im_/https://www.nist.gov/sites/default/files/styles/thumbnail/public/images/2021/11/22/VenitlationTool_Graphic_960x600_v2-04.png?itok=cjmdT3cB" width="100" height="56" alt="Illustration shows particles as blue dots circulating through a living room via windows, fans and filters." typeof="foaf:Image"/> </a> </div> </div> <div class="nist-teaser__content-wrapper"> <header> <h3 class="nist-teaser__title"><a href="/web/20231129195846/https://www.nist.gov/news-events/news/2021/11/streamlined-nist-tool-could-help-homeowners-renters-reduce-airborne"><span property="schema:name">Streamlined NIST Tool Could Help Homeowners, Renters Reduce Airborne Exposure to COVID</span> </a></h3> <div class="nist-teaser__date"> <div class="daterange"><time datetime="2021-11-24T12:00:00Z">November 24, 2021</time> </div> </div> </header> <div class="nist-teaser__content"> <div property="schema:text" class="text-with-summary"> COVID-19 is still circulating in the U.S. and may once again gain traction as families and friends gather indoors over the holidays.
