9、differs from DIN 5034-1:1999-10 as follows: a) this document has been editorially revised; b) the normative references have been updated (e.g. to reflect the withdrawal of DIN 5035-1 and DIN 5035-2 and their replacement/partial replacement by DIN EN 12464-1 and DIN EN 12665). Previous editions DIN 5

11、 instance the illuminance needed to fulfil a visual task, or the limitation of glare; its biological effects, for instance its impact on health, well-being and performance; thermal comfort, e.g. the limitation of harmful exposure to radiation and heat; energy efficiency, e.g. reducing energy consump

12、tion in buildings through the use of daylight. This standard specifies minimum requirements for achieving, by means of natural light, an adequate subjective impression of brightness indoors, and for providing a sufficient view out. In addition, requirements for the duration of sunshine exposure with

13、in habitable and occupied rooms are given. At present there is not enough knowledge of the biological effects of daylight to deal with them in a standard. This standard gives information on how to use daylighting to provide adequate lighting within interiors, and how to limit glare and heat irradiat

14、ion. Partial characteristics regarding the energy efficiency of lighting with daylight can be calculated on the basis of this standard. The standard applies to all occupied rooms, including work rooms within the meaning of the German Lnder building regulations and/or the Arbeitsstttenverordung (Germ

15、an Workplaces Ordinance). The standard also applies to all workplaces other than habitable rooms (such as workplaces in warehouses), except where daylighting is contrary to the nature and role of the work at hand. 2 Normative references The following referenced documents are indispensable for the ap

21、intended or is suitable for human occupation for more than a brief duration NOTE The term “occupied room” includes habitable rooms, work rooms and the other rooms defined below. 3.2 habitable room occupied room in a dwelling such as a living room, bedroom, study, childrens playroom, or an occupied r

22、oom in a facility whose purpose is comparable to living NOTE 1 Rooms which function as living areas, such as common rooms or lounges in senior citizens homes, boarding schools or child care centres are also considered as habitable rooms. This does not include, however, rooms which are primarily used

23、 for sleeping, such as accommodations in a hotel, etc. NOTE 2 Kitchens, halls and other areas which are not occupied for a long period are not considered as habitable rooms even if they are equipped with spaces for eating, resting or working. 3.3 work room room which is permanently equipped with wor

24、kplaces within a building 3.4 other room occupied room which is not a habitable room or work room NOTE For the purposes of this standard, “other rooms” may be classrooms, or patients rooms in outpatient and inpatient medical care faciltities, etc. 3.5 illuminance (at a point on a surface) E quotient

25、 of the luminous flux d incident on an element of the surface containing the point, by the area dA of that element (unit: lm m2) EN 12665 NOTE 1 The illuminance E is equivalent to the ratio of the luminous flux incident on an element of the surface to the area of that element . NOTE 2 The illuminanc

26、e E is expressed in lux (lx). 3.6 period of exposure to sunlight sum of periods (e.g. on a given day) during which the sun can be seen from a given point of view, both when it is at least 6 above the true horizon, and when it is over the natural horizon (e.g. line separating the sky and mountains, b

27、uildings, trees, etc.) NOTE The weather conditions are not taken into consideration here. 3.7 window daylight opening in a lateral vertical or inclined limiting surface of the interior to the exterior NOTE 1 This also covers roof windows and doors and walls with translucent surfaces. NOTE 2 Informat

28、ion on the dimensions of windows relate to the shell of the building, unless otherwise stated. This relationship is characterized by the index “r” after the relevant dimension, if this seems necessary. DIN 5034-1:2011-07 6 3.8 brightness attribute of a visual sensation according to which an area app

29、ears to emit more or less light EN 12665 NOTE 1 Brightness is equivalent to a subjective perception of luminance. NOTE 2 Unlike illuminance and luminance, brightness is not a measurable physical quantity. 3.9 luminance (in a given direction, at a given point of a real or imaginary surface) L quantit

30、y defined by the equation (unit: cd m2= lm m2 s1) dcosdd2AL = where L is the luminance in a given direction or at a given point of a surface; d is the luminous flux transmitted by an elementary beam passing through the given point and propagating in the solid angle d containing the given direction;

31、dA is the area of a section of that beam containing the given point; d is the solid angle; is the angle between the normal to that section and the direction of the beam. EN 12665 NOTE 1 Luminance L is equivalent to the ratio of the luminous flux emitted from a surface area in a specified direction t

32、o the product of the radiated solid angle and the projection of the surface area onto a plane perpendicular to the viewing direction. NOTE 2 Luminance is the ruling photometric value for the impression of the brightness of a surface. 3.10 usable luminous exposure HNutzintegral of the illumination by

33、 daylight at a workplace or within an area of an interior room during work hours, disregarding any times during which the maintenance value of the illumination level mis exceeded NOTE 1 Periods during which a predetermined illumination level, such as the maintenance level of the illuminance, is exce

34、eded are not taken into account for certain considerations, such as energy savings, even though these times may be beneficial for humans. NOTE 2 The usable luminous exposure can be determined for a specific day, month, season or for the entire year. 3.11 relative usable luminous exposure HNutz,rel r

35、atio of the usable luminous exposure to the product of the maintained illuminance mand the respective working time NOTE The relative usable luminous exposure HNutz,relis expressed as a percentage %. DIN 5034-1:2011-07 7 3.12 period of use tNutztime during which a given illuminance produced by daylig

36、ht only is attained or exceeded at a workplace or in a given area of an interior space NOTE The period of use can be determined for a specific day, month, or season, or for the entire year. Another term for this is daylight autonomy. 3.13 relative period of use tNutz,relratio of the period of use to

37、 the respective working time NOTE The relative period of use tNutz,relis expressed as a percentage %. 3.14 rooflight daylight opening in the ceiling of a room, which in most cases is also the roof of the building NOTE There are many different types of rooflights, e.g. dome lights, ridge roof or curv

38、ed continuous rooflights, and shed lights, and the glazings may have various angles of inclination. 3.15 room width b extent of the room measured parallel to the window NOTE 1 The room width b is expressed in metres (m) NOTE 2 If there are windows in several walls of a room, the room width shall be

39、taken as the extent of the room measured parallel to the largest window. Where the windows are all of the same size, the room width is given by the longest wall; if all walls with windows are equally long, the room width is determined based on the use of the room. 3.16 room depth a extent of the roo

40、m measured at a right angle to the room width b NOTE The room depth a is expressed in metres (m). 3.17 daylight guidance system system of reflective, refractive or diffractive elements which direct the daylight deeper into the room or onto its ceiling in order to achieve a higher illuminance at the

41、back of the room and for greater uniformity of lighting throughout the room NOTE Daylight guidance systems are, for example, blinds with reflective or specially formed slats, as well as light-guiding glasses. 3.18 daylight control system system consisting of an opening for allowing light to enter, a

42、 light-guiding medium, and an opening for allowing light to exit, the purpose of which is to bring daylight into interiors NOTE 1 Daylight control systems can supply interiors without windows with daylight. NOTE 2 Daylight control systems are, for example, heliostatic systems with light pipes, or li

43、ght openings with mirror-coated light control channels. DIN 5034-1:2011-07 8 3.19 daylight factor D ratio of the illuminance, Ep, at a point on a given plane due to light received directly or indirectly from a sky of known or assumed luminance distribution, to the illuminance, Ea, on a horizontal pl

44、ane due to an unobstructed hemisphere of the sky, disregarding the direct components of both illuminances 100ap=EED % NOTE This factor allows for the effects of glazing, dirt accumulation and window frames, transoms, etc. For the purposes of this standard, a CIE standard overcast sky 1 is assumed, i

45、n which case the daylight factor is constant for all points in a room. 4 Requirements for daylight openings 4.1 General Rooms intended for human occupation should receive sufficient daylight and should have a view out. For the purposes of this standard, both windows and rooflights are deemed dayligh

46、t openings. Windows provide visual contact between interiors and exteriors (view out), provide natural lighting, and generate a pleasant level of brightness in interiors. Windows shall be sufficiently large to fulfil these purposes. Rooflights provide interiors with natural and uniform lighting. To

47、achieve this, they shall be sufficiently large and evenly distributed across the roof (see 4.3.1.2). 4.2 View out 4.2.1 General A view out that is as unhindered as possible is important for human beings. It is therefore necessary to provide occupied rooms with windows with transparent, undistorted a

48、nd neutral-coloured glazing. Although rooflights allow occupants to discern weather conditions and assess the time of day, they do not generally provide much of a view out. Therefore, they cannot take the place of windows in providing a sense of psychological well-being. However, rooflights can be used to achieve more evenly distributed lighting. 4.2.2 Windows in habitable rooms According to 2, to ensure an adequate view out, windows should meet the following requirements
