19、SUNG ZUSAMMENFASSUNG Das Jahr 1991 wurde von der CIE zum ersten Jahr des internationalen Tageslichtmessungs- Programms (IDMP) erklrt. Ziel dieses Programmes ist es, weltweit die Tageslichtverfgbarkeit auf einer gemeinsamen Grundlage zu messen. Es existieren zwei Arten von IDMP- Mestationen: “allgeme

20、ine Mestationen“, die im wesentlichen Beleuchtungsstrke und Bestrahlungsstrke messen, und “Forschungsstationen“, die auch die Verteilung der Himmelsleuchtdichte und andere meteorologische Parameter messen. Diese Verffentlichung beschreibt die an diese beiden Mestationen gestellten Anforderungen im H

21、inblick auf Messungen und Instrumente und liefert Richtlinien und Empfehlungen fr Qualittskontrolle, Archivierung und Verbreitung der Daten.

FORE WORD Technical Committee 3-07 of the CIE was established to prepare a programme of intemational collaboration in daylight availability measurements. At present, there are few sites throughout the world for which systematic records o

23、f daylight exist: too few, either for accurate long-term prediction of daylight illuminances in buildings or for verification of recent theoretical models of sky brightness. There is a need to establish many more stations for recording daylight availability throughout the world, and there is a need

24、to establish conventions of measurement practice so that data collected in different countries are comparable. The CIE designated the year 1991 “International Daylighting Measurement Year“ as the first year of the “International Daylighting Measurement Programme“, referred to as the IDMP, dedicated

25、to the late Prof. Jurgen Krochmann. Under this programme, measuring stations throughout the world participate in a coordinated effort of daylight availability recording. Stations fall in two categories: the General Class, in which illuminances and irradiances are the principal quantities measured; a

26、nd the Research Class, in which the stations make continuous recordings of sky luminance distributions, as well as of illuminances, irradiances and other meteorological quantities. In addition, it is expected that one or two establishments will act as coordinating centres for the IDMP. The requireme

27、nts of General Class Stations and Research Class Stations and the protocol and format of data for international exchange of results are given. Between 1987 and 1993, eight drafts of this document were produced prior to this final one. Each draft was reviewed by the members of TC 3-07. Unfortunately,

28、 the committee was not able to finalize this document before the beginning of the IDMP. A positive consequence of this delay is that additional recommendations, based on the experience gathered by IDMP stations operators since 1991, particularly concerning data quality control and formatting, could

29、be included in this guide in the form of complementary appendices. 1 COPYRIGHT International Commission on IlluminationLicensed by Information Handling ServicesCIE 108 94 Wl 9006345 0004978 203 CIE 108-1994 2. PART A: GENERAL CLASS STATIONS 2.1 Introduction Many General Class stations are required t

30、o cover the different daylight climates of the world. The resources needed to cooperate in the programme are at a level appropriate for a research project in a district meteorological station, a school of architecture, or a university department which has an interest in daylighting but does not nece

31、ssarily have specialist staff and equipment. The measurements will be required to be of sufficient accuracy for practical calculations in lighting design; above all, the aim is to collect design data for the countries taking patt. 2.2 The site 2.2.1 Selection of sife There are two requirements. The

32、first is that there exists a site from which the sensors have an extensive view of the sky. Continuous obstructions to light, such as adjacent buildings and trees, should not be higher than 0,08 radians (4,6 degrees) above the horizon; a continuous obstruction 0,08 radians high reduces by 10% the il

33、luminance on vertical surfaces from an isotropic sky. In any quarter of the sky (for example between North and East in azimuth) the total solid angle subtended by obstructions should not exceed 0,13 steradians and preferably be significantty less. It is necessary, with most types of equipment, to ho

34、use the controller and data-recorder in a secure environmentally-controlled room near the sensors. In many places, lightning protection to the sensors is required. The second requirement of a recording station is that personnel can be made available for maintenance of the equipment and for statistic

35、al presentation of the results. The sensors and the data recorder may require attention almost daily during the complete period of daylight measurement. For international exchange of data, stations will be required to reduce the measured values to specified statistics and to present the results in a

36、 standard format. 2.2.2 Description of the site The following information will be required when measured data are presented. A standard data presentation format is described in section 4, Part C of this Guide. Name of principal investigator, postal address, telephone, telex and facsimile numbers. La

37、titude, longitude, elevation, time zone of measuring site. A concise verbal description of the climate and of any local factors, such as pollution sources, which may affect daylight availability. Details of local meteorological stations. A topographic map showing the land within a 5-kilometre radius

38、 of the site. Either mean ground reflectance measured at hemispherical incidence or a description of the ground surface within the 5-kilometre radius. Photographs of the view from the sensors in the four cardinal directions, and a stereographic drawing of the sky vault showing all obstructions. A li

39、st of the measuring and recording equipment, including manufacturers names and model numbers, and details of calibration, A description of any special local factors affecting the daylight measurements or the processing of results. 2 COPYRIGHT International Commission on IlluminationLicensed by Infor

I Basic sef The basic set of measurements made by a station in the General Class should be: a) Global horizontal illuminance (Evg), b) Diffuse horizontal illuminance (E, on-site observations will be required

41、, otherwise. This should be based on a subdivision of the sky into the nineteen zones shown on Figure 3.1: I No*h Figure 3. i: Subdivision of the sky for cloud assessment (stereographic projection). Angular size on zones: lowest band (1-12) O“ to 30“ elevation; size: 0,31 steradians central band (13

Total cloud cover i

43、n octas, based on an average of all zones. Then, for each zone, if a detailed analysis is possible: ii. The fraction of the zone covered by cloud, in octas. It should be coded as follows: O no cloud 1-7 8 zone completely covered 9 one-eighth to seven eighths of zone covered by cloud zone obscured, o

44、r cloud cover cannot be estimated. iii. The principal cloud type in the zone (the cloud type covering the greatest area of sky). It should be coded as follows, using WMO classification of cloud type: O 1 2 3 4 5 6 7 8 9 10 11 no cloud present cirrus cirrocumulus cirrostratus altocumulus altostratus

45、nimbostratus stratocumulus stratus cumulus cumulonimbus cloud type cannot be assessed. Cloud cover and type might be assessed in one of the following ways: a. Subjective observations of the sky. It should be noted that, even with trained observers, considerable inaccuracies can occur, and this metho

46、d should be employed only when other means are unavailable. b. Analysis of full sky photographs, the photographic image of the sky should be overlaid with a grid or a dot pattern to assess the proportion of sky covered in various zones. Subjective estimates should not be made from unstructured photo

47、graphs. Care should be taken in assessing cloud near the horizon, and in the vicinity of the sun, where overexposure of the image may mask cloudiness. If there is doubt, categories ii.9 and iii.11 (above) should be used. c. Automatic analysis of cloud quantity from video camera image made through fi

48、lters. d. Analysis of satellite images. This may be done visually as for full-sky photographs, from standard weather satellite recordings, or automatically, using computer techniques. It should be noted that the distribution of clouds seen from space differs from that seen from a point on the ground

49、, due to the three-dimensional forms of clouds. The cloud assessed should be that lying within a ten-kilometre radius of the recording station. It is essential to ensure that the time of the satellite image corresponds with the appropriate recording time of the ground station. The method of cloud assessment should be listed in the standard site description. 10 COPYRIGHT International Commission on IlluminationLicensed by Information Handling Servic
