6、esie within the CXE. Early in 1957 the Scope Commiitee R) aeked the committee W-3.2. to “decide on one or a amall number of methods of daylight caloulation which the CIE oan recommend to the various interested professions“, and at a meting in Paris in September, 1957, the oommittee W-3.2. agreed to

7、prepare 8 WIE guide for the calculation of natural ligh- ting (inoluding 8unlight)tI. In November 1957 questionnaires wem rent out to the members of the committee, and the Britieh Expert Member Mr. P. Petherbridge accepted to prepare a draft to the guide (Part I, overaart sky). “hie draft was presen

8、ted to the committee in Bruesel8 in June, 1959, and a number of amendments were euggeated. The amended draft was oirculated to the members in October, 1959, and aso sent to the National Committees for information. This draft met with some approval but also with considerable oppoeition, particular- l

9、y from the French National Committee. The French Expert of E-j.2., Mr. Eecher-Desrivires subsequently agreed to prepare a new draft, vhich was ciroulated to the members late in 1960 and met with predo- minant approval. The then chairman, Dr. A. Drealer, Australia, how- ever, found that the acceptanc

10、e of this version would have been con- troversial to the inetructions given by the Scope Committee, and he raked this committee for advice. The Scope Committee from its meeting in June 1961 gave a detai- led instruction for the further work (which is quoted in full in the Proceeding8 from the Vienna

11、 session, p. 363). At a meeting in Copen- hagen in September 1961, attended by 10 members of the committee and also by the chairman of the Scope Committee,.Yrof. L. Schneider, Ger- many, the subject was very thoroughly discussed and it waa finally nnanimouely decided that the guide should put forwar

12、d an example of a “eimpletl method baeed on recently published Australian material, and in the eecond part of the guide all other available inethode of calculating daylight should be listed together with complete refe- rences. The Australian expert and chairman of the committee, Dr. A. Drealer, was

13、asked to prepare a draft of this new version of the guide. This draft wae oirculated to the members in Kay 1963 and discussed at the presessional meeting in Vienna in June, 1963. A aeries of amend- mente were adopted and passed to Dr. Dresler. Shortly after that, Dr. Dresler died, but the Australian

Mr. James C. Loweon and 31r. I). Hwhes kindly took the re- 6pOnSibilify for tile. It prove

15、d neoessary to rearrange 8ome of the contente and a general revision was finally undertaken. The revised draft was in the main preeented and discussed at the meetiw of the committee in Newcastle-upon-Tyne in April, 1965, where 14 members of the committee wcre present or represented. in the beginning

16、 of 1966 the new, ooapleted and revised draft from the present Australian au- thors was oirculated to the members of the committee for their final approval. At this time some neu viewpoints on the transmittance fac- tors of glasses had been diaculiseri internationally and had also been introduced in

17、 the discuesioa of the factors used in the guide. These problema were presented to the members in a circular letter and the vote of the experte were requested. The comments received from the experts were partly quite elaborate and particularly Belgium, France, Great Britain and U.C.S.R. had critical

18、 comenta or eugcested amend- ments. The chairman corresponded with all the experts mentioned and with the authors. This resulted in some minor, but partly oseential Improvements, which I hope will satisfy all concerned. The final edi- tion, wnich ia presented here, has taken into account the typogra

37、viding them with 8 meane of computing and checking interior daylight levele simply yet with adequete accuracy. In recent yema techniquee for predicting daylight levels have become more precise than they used to be, but have at the eame time become more complicated. The object of the guide le to redu

38、ce a few of these techniques into a method simple enough to apply to everyday lighting design probleme, (Part I). The CIE method is designed for simple and easy eetimation of the eufficiency of daylight in uncomplicated rooms under average oon- ditions. Conaequently, the accuracy to be expected is n

39、ot the highest ob- tainable, but still adequate for moat purposes. Usere are advised to read the preface and section 1.1. before applying the method. In addition, the Guide contains a comprehensive list of other.method8 of predicting daylight in buildings, (PA II) . From fus list those who would lik

40、e to epecialirte in daylight design can select the methods which will best aeme their pur- pose in any one ca8e. From the many methods available the Daylight Committee of the C.I.E. has selected as an example of a simple method of day- light prediction, techniques that were developed in Australia in
