Poor air quality has a negative impact on office workers

According to a new survey, indoor air pollution is prevalent in work places across Britain, potentially causing long-term health problems.

A YouGov survey commissioned by the Building Engineering Services Association (BESA) found that almost 70% of office workers believe poor air quality in their workplace is having a negative effect on their day-to-day productivity and well-being.

In addition, a third of office workers are concerned that poor indoor air quality could be having a bad effect on their health.

Opening windows is the most commonly used form of ventilation with 60% of office workers saying it is the first thing they do if they need ‘fresh air'. However, although this is seen as a natural response, opening office windows means that there is a risk of further polluting the working environment by letting in outdoor toxins, the survey found.

Given that we spend 90% of our time indoors and are spending, on average, 212 days a year at work, BESA has called on the industry; building managers and the general public to ensure proper, effective, well maintained ventilation systems are operating in all offices across the UK.

Those office workers surveyed, reported suffering regularly from symptoms commonly linked to poor indoor air quality including lapses in concentration, fatigue, irritated eyes and decreased productivity.

Almost 40% of office workers who suffer from at least one of the symptoms listed believes poor ventilation is the main reason for the problems they experience. The BESA survey follows a report published by the Royal College of Physicians earlier this year, which revealed that air pollution, both indoor and outdoor, could be linked to at least 40,000 premature deaths a year in the UK.

BESA chief executive Paul McLaughlin said: 'Many people in the UK end up working more than 40 hours per week and, generally, we spend upwards of 90% of our time indoors. It is, therefore, crucial that buildings provide a healthy working environment.

'More and more people are becoming aware of the inadequate ventilation options in their offices, as well as the negative effect this is having on their health and their productivity.”

He added: 'There is a perception that a lack of windows contributes to poor indoor air quality (IAQ), but in reality, we need proper, well maintained air conditioning and ventilation systems in place. We need to make our buildings a safe haven for occupants, to protect them from the worst impacts of outdoor pollution as well as providing good quality, healthy indoor air.'

Commenting on the survey results, the Royal College of Physicians' special adviser on air quality, Professor Stephen Holgate said: 'As we noted in our report: ‘Every breath we take: the lifelong impact of air pollution', indoor air pollution is often an area which is overlooked. Poor ventilation is one part of this problem and, with the drive to reduce energy costs by making spaces more airtight, things will only get worse.

'We now know that air pollution has a substantial impact on many chronic long-term conditions, increasing strokes and heart attacks in susceptible individuals. That is why this is not just a job for government, local authorities or business - as individuals we can all do our part to reduce pollutant exposure,' added Professor Holgate.

Dr. Prashant Kumar from the Department of Civil & Environmental Engineering at the University of Surrey added: 'The World Health Organisation ranks air pollution as the third most significant health risk worldwide. Indoor air quality is greatly affected by the ventilation conditions of a household, commercial or workplace buildings.

'Modern buildings and workplaces are usually made airtight to conserve energy, but this can in fact compromise the indoor air quality due to lack of sufficient air changes. The results of this survey are very useful and indeed pertinent, not only for the general public but also for the scientific community and the urban planners.'

BESA is collaborating with a number of industry bodies including the Chartered Institution of Building Services Engineers (CIBSE) and Institute of Healthcare Engineering & Estate Management (IHEEM) to raise awareness about IAQ and produce detailed guidance for contractors, designers and facilities managers.
