Barrier to Entry

by Katie Lee

— By Bryan Campbell —   When developing on potentially contaminated property, you can protect your new building from VOCs with a vapor barrier.     Historically, the term “vapor intrusion” was discussed only in association with the most heavily contaminated properties. Now, with the emergence of new stricter guidelines, the United States Environmental Protection Agency (EPA) and many state regulatory agencies identify vapor intrusion as a major driver on many sites, including those with little to no soil or groundwater contamination. In some cases, potential vapor intrusion is not …

Breath of Fresh Air

by Katie Lee

— By Chris Marasco — Improving IAQ to better protect your customers.   The COVID-19 pandemic has been a catalyst of disruption for more than a year. In 2020, the virus quickly shut down many restaurant locations while forcing retail businesses to enforce strict guidelines that instructed customers to wear masks and stand 6 feet apart. In many situations, consumers shifted toward online stores to make their purchases as opposed to gathering in person at a brick-and-mortar location. While the pandemic turned many lives upside down, one positive outcome was …

The Pacific Northwest and Mountain West have experienced unprecedented temperatures, with highs in Portland, Ore., reaching a record 116 degrees in August.

Free & Fair Air

by Katie Lee

— By Ramez Naguib, P.E. — Effect of air filter rating on energy consumption in restaurants during COVID-19.   This we know: COVID-19 is primarily transmitted from person to person through respiratory droplets, which are then released when someone with COVID-19 sneezes, coughs or talks. Infectious droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Current data do not support long range aerosol transmission of SARS-CoV-2, such as seen with measles or tuberculosis. Short-range inhalation of aerosols is a …

by Katie Lee

Morris Plains, N.J. — Natural and organic foods retailer Whole Foods Market has adopted Honeywell’s Solstice® N40 (R-448A) lower global-warming-potential (GWP) refrigerant in its stores across the United States as it seeks to reduce refrigerant emissions under the U.S. Environmental Protection Agency’s GreenChill program.
