The quality of the indoor environment is a subject of increasing concern to employers. While the health risks presented by "sick buildings" is often difficult to substantiate.

There is little doubt that poor quality workplace air can be a significant source of discomfort to employees.

A thorough assessment should enable staff to communicate their concerns regarding the level of control they have over the workplace environment, whether this is thermal conditions, ventilation, lighting etc.

There are also a number of environmental parameters which are useful in establishing if a poor air quality may be contributing to employee dissatisfaction. Coupled with this the company can undertake independent inspection and microbiological testing of ventilation systems and air hygiene.

Ethos Environmental Ltd has undertaken numerous such assessments in office and educational establishments.
