Left alone, these areas may develop mould and fungi. Relative humidity levels above 70% may lead to the development of condensation on surfaces and within the interior of equipment and building structures. Low relative humidity levels may also cause static electricity build-up and negatively affect the operations of some office equipment such as printers and computers. Relative humidity levels below 20% can cause discomfort through drying of the eyes and mucous membranes and skin. In Appendix F, ASHRAE states “there are no established lower humidity limits for thermal comfort consequently, this standard does not specify a minimum humidity level.”ĬSA recommendations for temperature (above) are listed at an average of 50% humidity. The ASHRAE Standard 55-2013 uses a graphic comfort zone method that takes into account the factors of relative humidity, humidity ratio, operative temperature, and wet bulb temperature with notes on clothing, metabolic rate, radiant temperature, and air speeds. A list of temperature requirements found in legislation is available in the OSH Answers document Temperature Conditions - Legislation. In some situations, legislation may have specific requirements. Some people may feel uncomfortable even if these values are met. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) Standard 55 - 2013 Thermal Environmental Conditions for Human Occupancy offers that these recommended temperature ranges have been found to meet the needs of at least 80% of individuals. NOTE: CSA indicates both of these conditions are based on Table 3 from ASHRAE Standard 55, at 50% relative humidity and average air speed of <0.15 m/s. Winter conditions: optimum temperature of 22☌ with an acceptable range of 20-23.5☌.Summer conditions: optimum temperature of 24.5☌ with an acceptable range of 23-26☌.Recommendations provided by CSA Z412-17 Office Ergonomics – An application standard for workplace ergonomics include:
