It is merelyinformative

25、and does not contain requirements necessaryfor conformance to the standard. It has not been pro-cessed according to the ANSI requirements for a standardand may contain material that has not been subject topublic review or a consensus process.)FOREWORDANSI/ASHRAE Standard 55-2013 is the latest editio

26、n ofStandard 55. This edition incorporates eighteen addenda tothe 2010 edition that were written with a renewed focus onapplication of the standard by practitioners and use of clear,enforceable language.The core of the standard in Sections 4 and 5 specifiesmethods to determine thermal environmental

27、conditions (tem-perature, humidity, air speed, and radiant effects) in buildingsand other spaces that a significant proportion of the occu-pants will find acceptable at a certain metabolic rate andclothing level. The comprehensive analytical method to deter-mine these conditions uses calculation alg

28、orithms included inthe standard and appendices, all of which are implemented inthe ASHRAE Thermal Comfort Tool.4The standard contains a graphical method of compli-ance, which is familiar to many users, yet is permitted to beused only in limited circumstances. Given the widespread andeasy accessibili

29、ty of computing power and third-party imple-mentations of the analytical method, it is expected that moreusers will favor the comprehensive analytical methods overthe graphical method.Section 6 contains requirements for demonstrating that adesign of an occupied space or building meets the comfortreq

30、uirements in Sections 4 and 5. Section 7 includes require-ments for the measurement and evaluation of existing thermalenvironments and is also applicable to commissioning.Since the two personal characteristics of occupants (met-abolic rate and clothing level) vary, operating setpoints forbuildings a

31、re not mandated by this standard.Standard 55 was first published in 1966 and republishedin 1974, 1981, and 1992. Beginning in 2004, it is nowupdated using ASHRAEs continuous maintenance proce-dures. According to these procedures, Standard 55 is continu-ously revised by addenda that are publicly revi

32、ewed,approved by ASHRAE and ANSI, and published and postedfor free on the ASHRAE website.The eighteen addenda published since 2010 are summa-rized in detail in Informative Appendix M, and the most note-worthy changes are summarized here:a. The normative body of the standard, comprising Sections3 thr

33、ough 8, have been rewritten and reorganized.Requirements are more clearly stated, definitions areadded to Section 3, and informative supporting informa-tion has been moved from the body to informative appen-dices.b. Procedures are clarified and appear in a more sequentialmanner. For example, a “repr

34、esentative occupant” withrepresentative “clothing insulation” and “metabolic rate”shall be defined as input into thermal comfort calculations.c. The cooling effect of air movement now applies to natu-rally conditioned spaces as well as mechanically condi-tioned spaces, and in each case correction fa

35、ctors aregiven that adjust the comfort boundaries when air move-ment is present.d. A new alternate procedure for estimating occupant cloth-ing insulation based on outdoor weather was added. Thisprocedure is based on extensive field research and can beused for design calculations, annual simulations,

36、 andcontrol of occupied spaces.e. Major revisions to Section 7 procedures for measuringcomfort in existing spaces including survey and physicalmeasurement methods and a new section on evaluatingand reporting results.f. The standard now says that two of the key comfort param-eters, air speed and air

37、temperature, must be calculatedas an average that the occupant experiences at threeheights across the body and over a period of time.1. PURPOSEThe purpose of this standard is to specify the combina-tions of indoor thermal environmental factors and personalfactors that will produce thermal environmen

38、tal conditionsacceptable to a majority of the occupants within the space.2. SCOPE2.1 The environmental factors addressed in this standard aretemperature, thermal radiation, humidity, and air speed; thepersonal factors are those of activity and clothing.2.2 It is intended that all of the criteria in

39、this standard beapplied together since comfort in the indoor environment iscomplex and responds to the interaction of all of the factorsthat are addressed.2.3 This standard specifies thermal environmental conditionsacceptable for healthy adults at atmospheric pressure equiva-lent to altitudes up to

40、3000 m (10,000 ft) in indoor spacesdesigned for human occupancy for periods not less than 15minutes.2.4 This standard does not address such nonthermal environ-mental factors as air quality, acoustics, and illumination orother physical, chemical, or biological space contaminantsthat may affect comfor

41、t or health.3. DEFINITIONSadaptive model: a model that relates indoor design tempera-tures or acceptable temperature ranges to outdoor meteoro-logical or climatological parameters. Note: Adaptive model isanother name for the method described in Section 5.4,“Determining Acceptable Thermal Conditions

42、in Occupant-Controlled Naturally Conditioned Spaces.”)air speed: the rate of air movement at a point, without regardto direction.air speed, average (Va): the average air speed surrounding arepresentative occupant. The average is with respect to loca-tion and time. The spatial average is for three he

43、ights asdefined for average air temperature (ta). The air speed is aver-aged over an interval not less than one and not more thanthree minutes. Variations that occur over a period greater thanthree minutes shall be treated as multiple different air speeds. ASHRAE (www.ashrae.org). For personal use o
