Ashrae thermal comfort temperature range. Relative humidity rh is a measure of the moisture in the air. The most recent version of the standard was published in 2017. The results are displayed on a psychrometric or a temperature relative humidity chart and indicate the ranges of temperature and relative humidity that will be comfortable with the given the values input for the remaining four parameters. There is no recommended lower level of humidity for achieving thermal comfort but very low humidity can lead to increased static electricity and health problems such as skin irritation.

Thermal environmental conditions for human occupancy is an american national standard published by ashrae that establishes the ranges of indoor environmental conditions to achieve acceptable thermal comfort for occupants of buildings. It calculates this value based on user inputs for the six main factors affecting occupant comfort. Ashrae recommends that relative humidity be maintained below 60. It was first published in 1966 and since 2004 has been updated every three to six years.

The cbe thermal comfort tool for ashrae 55 allows users to input the six comfort parameters to determine whether a certain combination complies with ashrae 55. Optimum temperature of 22 c with an acceptable range of 20 23 5 c. There are many additional factors such as activity level clothing age gender and health status that affect your comfort. In this example the surface temperatures range from 65 f to 72 f and mrt is calculated at 69 1 f.

Radiant heat hot surfaces or radiant heat loss cold surfaces are also important factors for thermal comfort. Csa indicates both of these conditions are based on table 3 from ashrae standard 55 at 50 relative humidity and average air speed of. The standard had previously allowed modest increases in operative.

Comfort conditioning can increase thermal comfort decrease energy use. Ashrae thermal comfort tool also can calculate percent of persons dissatisfied ppd the percentage of occupants that would find certain thermal conditions unsatisfactory. Temperature thermal comfort is determined by the room s temperature humidity and air speed. Therefore the use of ele vated air speeds to widen the acceptable range of thermal conditions has been modified and expanded section 5 2 3.

Ashrae standard 55 2017 thermal environmental conditions for human occupancy notes that for thermal comfort purposes temperature could range from between approximately 67 and 82 f. It could also be about sweat and the building might matter too. It s not the heat.
