Therefore, acceptable humidity levels in office buildings are generally within the “safe zone” of 40 to 60 percent RH. The purpose of this OC, which is based on THSD Minute THSD C5/T/4/92, is to provide practical information for Specialist Inspectors dealing with requests for advice on Sick Building Syndrome (SBS).

Thank you all in advance! Relative humidity is the ratio between the actual amount of water vapour in the air and the maximum amount of water vapour that the air can hold at that air temperature.
Welcome Guest! As a standalone parameter, humidity is unlikely to cause thermal discomfort and levels outside the 40-60% range can easily be tolerated. (7) CIBSE Guides Volumes A and B published by the Chartered Institute of Building Services Engineers, London.
Speak to one of our experts today to learn more about humidification for your office. Note that in the winter the lower humidity tends to lead to a reduction in skin hydration, making the skin more vulnerable. We measured skin hydration levels in office workers. In practice, you're probably right.
External supplier supplied thier readings to me about 3 months ago. The symptoms generally increase in severity over the working shift and diminish on leaving the building at the end of the working day. Office machinery and equipment may also be a possible source.8 Although the potential range of pollutants in offices and similar environments is enormous, levels have generally been found to be minute, in parts per billion compared with currently-established occupational-exposure standards quoted in parts per million. Humidity levels in your home can make a big difference in your level of comfort.
For more information on our evaporative humidifiers as well as other available products and services, it is like banging your head against a brick wall, the staff are constantly complaining about the heat and humidity, and even with the support of our senior management team, we do not seem able to get anywhere. In theory, no, seanie. "The code states: "Optimum comfort for sedentary work is between 20°C and 26°C, depending on the time of year and clothing worn.

There is no "legal value" of humidity, although there may be values for diffrent environments from professional bodies such as CIBSE & ASHRAE
The Guidelines also suggested that a common sense approach when air conditioning systems are "off" is to evacuate affected parts of the building when the working conditions become unacceptably hot, cold or smelly.With respect to air temperature, in a still office environment, there should be no adverse health effects (for normally healthy people) from working when the dry bulb air temperature (that is the inside thermometer) is within the range of 18 to 30 degrees Celsius. The ground floor staff constantly complain about being cold from the Air Circulation system and the first floor are always too hot and are starting to devolp skin conditions in some areas.
(Advice: from the CSA Standard CAN/CSA Z412-00 (R2005) - "Office Ergonomics" which gives acceptable ranges of temperature and relative humidity for offices in Canada. There may be some other options in some situations, like working from home as a short term measure, but the emphasis should be on fixing up the air conditioner as soon as possible.If the inside temperature goes above 30 degrees Celsius and staff are feeling unwell then measures must be taken to cool them down, and they should complete an incident form to document the situation.
