April – Air
A recent Harvard School of Public Health Cognitive Function Study “CogFx” found an overwhelming link connecting indoor air quality to human cognition. This study identified nine different cognitive function variables decreased as CO² levels increased. Intuitively this a very logical conclusion. But, what is most surprising was that the decrease in cognitive function started at CO² concentrations well below current code requirements.
Of course Indoor Air Quality (IAQ) isn’t all about CO² concentration, it involves temperature, humidity, dust particles, VOC and other chemical off gassing from materials, among many other measures. So during April, our Market Group Sustainability Leaders and Advocates used an Awair Omni meter to measure some of these factors at each of our offices.
• On average, all Cuningham Group offices are under 600ppm CO² level which helps create a productive environment for all employees.
• There are some spikes in CO² concentration in smaller conference rooms that is only occasionally noticed.
• Average humidity is generally good for all offices but Phoenix, Las Vegas, and Denver sometimes are too dry.
• Average temperatures in offices generally stay between 72 and 77 degrees.
• Average chemicals and fine dust concentrations are generally within limits except for Phoenix Sky Harbor which was high for unknown reasons.
• There was a decline in CO² levels near the Green Wall in Phoenix.
• When there are spikes in CO² levels, especially in conference rooms, staff should open the door or bring in fresh air by other means to ensure highest cognitive function.
• Humidification of air especially in Phoenix, Las Vegas and Denver should be considered during times of very dry indoor air.
• Explore reasons why chemical and dust levels are higher in Phoenix than in other offices.
• Consider adding green walls in other Cuningham Group offices.
