BCD appraisals of luminaire brightness in simulated office
Jan n 1 sec 1 p 31-44: Results of research project in which inexperienced observers adjusted luminaire brightness in simulated office to BCD, (borderline between comfort and discomfort): 109 observers performed consistently in appraising six luminaire combinations: data are given from which glare prediction methods can be checked against actual conditions studied. Dec n 12 p 701-7: Further results in which variations in luminaires and surround were appraised by 10 observers making 750 evaluations; data for checking glare prediction formulas, and results on validity of averaging luminaire brightness, influence of ceiling brightness, and effect of prismatic plastic lenses.
