For commercial, institutional and industrial facilities attempting to maintain a healthy indoor air environment, ensuring regulatory compliance for outdoor air intake is a serious challenge that often results in wasted time and money. To help meet these standards and minimize the use of outdoor air, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) provides facility owners and operators with the Indoor Air Quality Procedure from Standard 62.1 that provides a series of complex equations designed to help reduce the minimum level of outside air intake. 

More and more frequently, when the mercury rises past a certain level, the Department of Energy and Environmental Protection will issue an air quality alert, warning parents with children, the elderly and people with respiratory issues who are most at risk to avoid the outdoors. But unexpectedly soaring temperatures can still arrive during autumn and increasingly so, in some regions of the world, in November and December.

As polluted air engulfs the rural areas of the United Kingdom, excessive smog closes schools and construction sites in China, and wildfires in North America send pollution levels skyrocketing, the quality of the air we are currently breathing is deteriorating on a global level and posing a serious threat to our health. In fact, according to the United States Environmental Protection Agency (EPA), air pollution causes more than three million premature deaths annually around the world – a number that many experts expect to double in the next 35 years.
