Ergonomics of the thermal environments--Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria
, International Organization for Standardization, Switzerland.
Engineered to absorb moisture, Nomex MHP dries faster than cotton the company says and offers a number of features for superior wearability, including a lighter weight and was proven the overall winner in key comfort criteria
in independent studies conducted by an institute for textiles and clothing.
ISO 7730 (2005) Ergonomics of the thermal environment--Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria
ON, provider of integrated distribution and sales of power and gas and the world's largest utility, Powerit and Diana technology platforms have been successfully applied in over 2,500 installations globally many in industry sectors that have high energy demand and/or specific comfort criteria
, including agriculture and food products, commercial and recreational facilities, retail space, forest products, mechanical fabrication and manufacturing, petroleum and petrochemical, and primary metals fabricators.
Occupant comfort criteria
are stricter for residences than for office space and wind tunnel testing showed comfort would not be satisfactory based on preliminary design properties.
This depends on the comfort criteria
for a building's specific use.
ISO standard 7730, 2005, Ergonomics of the thermal environment-Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria
First, ASHRAE Standard 55 2010 made changes to the draft local thermal comfort criteria.
Third, the local comfort criteria for floor temperature is based on occupants wearing lightweight indoor shoes.
This may lead to the conclusion that the acceptable thermal comfort criteria
for say an office may not be achievable in an underground railway environment and perhaps thermal comfort criteria
not quite equaling the office level maybe acceptable in such an environment.
We then give details of behavioral algorithms that are based on adaptive comfort criteria and survey data and have been developed to represent window opening and other adaptive occupant behaviors.
Contained within this document are the cooling season thermal comfort criteria to be applied to mechanically cooled buildings as well as the alternative adaptive thermal comfort criteria that may be applied to naturally ventilated office buildings or dwellings in free-running mode (outside the heating season) "where there is easy access to openable windows and occupants may freely adapt their clothing to the indoor and/ or outdoor thermal conditions".
