BSEE INDOOR AIR QUALITY


Corporate wellness has become a hot topic over the last few years, with employers and building managers becoming increasingly aware of how the oce environment can impact producvity. One element of this is air quality, and the importance of ecient venlaon. Steve Charles, Technical Consultant at Jaga, explains.


being rolled out at an


unprecedented rate, with nearly half of all UK companies establishing a comprehensive wellness plan. According to The Global Wellness Institute, the world market for workplace schemes is around $43bn, most of which are based in the US and Europe. The UK Government has also now explicitly come out in support of workplace wellness, with a Government green paper on work, health and disability stating: “Businesses drive our economy and are rightly focused on growth, productivity and delivering a return on their investments. Investing in workplace inclusivity, health and wellbeing is critical to these goals”.

A central tenet of these schemes is indoor air quality. Significant research has been undertaken to understand the role that air quality has on employee performance, yielding considerable results.


One such study was conducted by Harvard and Syracuse Universities. In order to measure the impact of air

quality, the researchers simulated environments with different levels of ventilation, carbon dioxide, and emissions from common office products. Participants were exposed to two different environments, one involving workers going about their usual tasks in typical office conditions, the other in a condition where ventilation was improved, and levels of carbon dioxide and emissions were reduced. The results were conclusive. Employees in the well-ventilated environment performed a massive 61 per cent better on cognitive tasks than they did in standard office conditions. Even more startling, the researchers found that by doubling the ventilation in the second environment, cognitive performance increased by more than 100 per cent. A separate study conducted by Harvard University on 10 different green- certified buildings found employees had 30 per cent fewer headaches and respiratory complaints in their controlled air quality environments than those in typical office buildings. The study also showed employees performed nearly 27 per cent better on cognitive tasks. Finally, workers in the study slept better at night, tracked by a wristband measuring sleep quality.


This research, along with the growing


demand for defined workplace wellbeing strategies, highlights the vital importance of proper ventilation in corporate premises.


So, what do building managers and engineers need to know? Below are a few key factors to bear in mind when considering workplace ventilation.


Venlaon is key


Various studies have shown that indoor air pollution has increased in recent years. This is due to a variety of factors, including the construction of tightly sealed buildings, the reduction of ventilation rates to save energy and the
