ASHRAE Guidelines are developed under a review process, identifyinga guideline for the design, testing, application, or evaluation of a specific product, concept, or practice. As

11、a guideline it is not definitive butencompasses areas where there may be a variety of approaches, none of which must be precisely correct. ASHRAE Guidelines are writtento assist professionals in the area of concern and expertise of ASHRAEs Technical Committees and Task Groups.ASHRAE Guidelines are p

12、repared by project committees appointed specifically for the purpose of writing Guidelines. The projectcommittee chair and vice-chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, allmust be technically qualified in the subject area of the Guideline.Devel

13、opment of ASHRAE Guidelines follows procedures similar to those for ASHRAE Standards except that (a) committee balance isdesired but not required, (b) an effort is made to achieve consensus but consensus is not required, (c) Guidelines are not appealable, and(d) Guidelines are not submitted to ANSI

14、for approval.The Manager of Standards of ASHRAE should be contacted for:a. interpretation of the contents of this Guideline,b. participation in the next review of the Guideline,c. offering constructive criticism for improving the Guideline, ord. permission to reprint portions of the Guideline.ASHRAE

LIGHTING (DAYLIGHT)ILLUMINATI

21、ONStudies of illumination usually focus on the distributionof energy by intensity and sometimes by frequency in the vis-ible portion of the electromagnetic spectrum. Energy in thenon-visible portion of the electromagnetic spectrum, includ-ing both infrared and ultraviolet, can strongly affect occu-p

22、ants, materials, and even chemical, physical, and biologicalagents in a space. The main focus of most investigations ofillumination is on the support provided for task visual perfor-mance. In some locations, especially regions more distantfrom the equator, the absence of daily exposure to bright lig

23、htcan cause seasonal affective disorder (SAD). Brief exposureto very bright lights has been used to counteract this effect(Lewy et al. 1985).7.1 Daylight Interactions. Some studies have found thataccess to daylight or windows is associated with lower preva-lence of SBS symptoms. However, it appears

24、that an impor-tant contributor to the measured outcomes is access to viewsto the outside. In one study, researchers found that the largerthe view available from occupants desks, the fewer com-plaints the occupants had about all other ambient factors,regardless of objective measurements of those cond

25、itions(Heschong Mahone Group 2003).7.2 DaylightElectrical Lighting Interactions. Light fromeither an electric or a daylight source is necessary for use ofmost building spaces. The spectral distribution and intensitywill affect peoples responses to the light in a space. Light canaffect mood and perfo

26、rmance. Proper color rendition is neces-sary for artists and textile and other product designers, as wellas medical diagnostics and many other tasks, including per-sonal hygiene.7.3 DaylightAcoustical Interactions. When uninsulatedsingle-pane glazing open windows or skylights are used toadmit daylig

27、ht, noise can enter and be a significant distur-bance to occupants. Such noise may interfere with proper taskperformance. In addition, the hard resonant surfaces of largeareas of glass may increase the reverberation time in a spaceand should be considered in acoustic design.Some skylights can amplif

28、y the sound of rain and hailstriking the panels.Visual access to a noise source may increase, or reduce,its acceptability. Noises that do not have a clear source orcause may be more disturbing than those that are easily under-stood via visual cues. Thus, a view to the outside that includesthe noise

29、source may actually reduce disturbance from thenoise. This is especially true of unpredictable noises, such asthose from construction sites or emergency vehicles, that inthe absence of further information might suggest danger.Implications: Operable windows should be located awayfrom outdoor noise so

30、urces and be provided with some meansto dampen incoming noise when noise sources are unavoid-able. Consider locating activities that require quiet environ-mental conditions away from outdoor and indoor noisesources.8. LIGHTING (ELECTRIC)7.4 Electric Lighting (Electric)Acoustical Interac-tions. Elect

31、ric lighting fixtures emit sound that can be audibleand even loud enough to be annoying, especially light sourcesthat depend on electromagnetic ballasts, e.g., gaseous dis-charge lamps such as fluorescent or metal vapor. In extremecases, noise from electrical devices can interfere with propertask pe

32、rformance. Often the primary surface providing acous-tical absorption within a room is the ceiling, since acousticalceiling tile is generally the lowest-cost material available tocontrol reverberation time within a room. Typical recessedluminaires (installed in the ceiling grid) tend to occupyapprox

33、imately 15% of the ceiling surface, thus limiting theavailable space for the application of ceiling tile to controlreverberation. It can be better to use pendant luminaires thatdo not occupy the ceiling plane and that, when used withhighlight-reflectance ceiling tile, provide high levels of indi-rec

34、t lighting without substantial glare.Implications: Designers should select light sourceswhose noise emissions are compatible with the functions ofthe space. For example, in a library, theatre, or study hall,especially quiet light sources are more appropriate. However,in a bar or nightclub, there wil

35、l usually be many sources ofnoise besides the illumination; thus, quiet illuminationsources are not as critical as in an office or conference roomor classroom where verbal communication is critical to theuse of the space. Guidance on appropriate noise levels inclassrooms is available from the Acoust

Theprimary ways to a

40、chieve IAQ include the use of ventilation,either mechanically with equipment or passively through win-dow openings. Mechanical ventilation is often accompaniedby the noise of fans, airflow through duct elbows andbranches, mixing boxes, dampers, and diffusers or even thesounds of air leakage from the

41、 ductwork or other system com-ponents. This HVAC noise will generally be dominated bylow-frequency sound, which may in extreme cases eveninduce secondary vibration in walls, floors, and other surfaces(in addition to that caused by improperly isolated or mountedequipment). See Indoor Air Quality Guid

42、e: Best Practices forDesign, Construction, and Commissioning (ASHRAE 2009a)for a more detailed discussion.If ventilation equipment is noisy, it may not be used asintended by the designer. For example, teachers tend not tooperate noisy unit ventilators in their classrooms, resulting inreduced outdoor

43、 air ventilation and increased indoor sourcepollutants. Home occupants tend not to operate noisy bath-room or kitchen fans, resulting in a buildup of moisture, com-bustion gases, or other products and by-products of activitiesconducted in the home. Because of this interaction, Standard62.2 requires

44、quiet fans to achieve its IAQ objective.Passive control of IAQ is often attempted with the use ofoperable windows. Opening windows to “get some fresh air”may not be an option where noise enters a space from out-doors. In busy urban areas or areas adjacent to highways, rail-ways, airports, playground

45、s, or factories, the ambient noiselevels can deter people from opening windows. But it shouldbe recognized that the primary purpose of a window is to letdaylight in while providing visual relief by making it possiblefor occupants to see outside. It is not necessary to use opera-ble windows to allow

46、outdoor air entry; an acoustical plenumor acoustical louvers can be used in conjunction with a win-dow (above, below, or to the side) to allow outdoor air entrywithout allowing noise to enter.Addendum b to Guideline 10-2011Modify Section 6.6 as follows.
