(from Table 1).Since 1958 the Illuminating Engineering Society has published illuminance recommendations in table form. These tables cover both generic tasks (reading, writing etc), and 100's of very specific tasks and activities (such as drafting, parking, milking cows, blowing glass and baking bread).All tasks fall into 1 of 9 illuminance categories, covering from 20 to 20,000 lux, (2 to 2000 footcandles). The categories are known as A - I, and each provide a range of 3 iluminance values (low, mid and high). See Table 1.STEP 4 - select WEIGHTING factors:for category A-C use 'Table 1a' below.for category D-I use 'Table 1b' below.========================================================================== TABLE - 1a - (for Categories A-C)==========================================================================-1 0 +1Occupant agesunder 40 40-55 over 55Average room surface reflectancesmore than 70% 30-70% less than 30%INSTRUCTIONS for Table 1a: Add both weighting factors algebraically.If the total factor is -2 use the low illuminance value.If the total factor is +2 use the high illuminance value.If the total factor is 0 use the middle illuminance value.========================================================================== TABLE - 1b - (for Categories D-I)==========================================================================-1 0 +1Occupant agesunder 40 40-55 over 55Importance of speed and/or accuracy not importantimportant criticalReflectance oftask background more than 70% 30-70% less than 30%INSTRUCTIONS for Table 1b: Add all 3 weighting factors algebraically.If the total factor is -2 or -3 use the low illuminance value.If the total factor is +2 or +3 the high illuminance value.Otherwise use middle illuminance value.EXAMPLESTEP 1 - What illuminance is recommended for an adult aged 56, performing detailed accounting tasks of medium contrast or small size?STEP 2 - From 'Table 1' we identify CATEGORY' E' as the appropriate category.STEP 3 - From 'Table 1' we also identify the illuminance RANGE as 50-75-100 fc.STEP 4 - From 'Table 1b' we calculate the weighting factor:AGE - 56factor +1IMPORTANCE OF SPEED AND ACCURACY - (important)factor 0BACKGROUND REFLECTANCE - (medium contrast, about 40%)factor 0---------+1In accordance with 'Table 1b' instructions, we use a weighting factor of +1 and then select the middle value of 75 footcandles for the task.ROOM AND OCCUPANT CHARACTERISTICS Weighting FactorROOM AND OCCUPANT CHARACTERISTICS Weighting FactorSTEP 1 - What illuminance is recommended for an adult aged 56, performing detailed accounting tasks of medium contrast or small size?In accordance with 'Table 1b' instructions, we use a weighting factor of +1 and then select the middle value of 75 footcandles for the task.
