Abstract :
THE illumination of the auditorium in the Engineering Societies Building has been for several years the subject of study at the request of United Engineering Trustees, Inc., by Institute members specializing in lighting. Increased daytime use of film and slide projection had been hampered by daylight filtering through roller shades and the interior illumination had been pronounced obsolete, inadequate, and difficult to maintain. In an effort to improve the building facilities for their Founder Societies and associates, the board of trustees of United Engineering Trustees, Inc., undertook the modernization of this meeting hall and authorized the replacement of the false skylights with a more permanent boarding and a thoroughly modern lamp system.
