*NOTE: in the original BD+C reference guide, Table 1 is incorrectly referred to as Table 3. This was corrected in addenda issues 100000318 and 100000319. *Add the following paragraph before Table 1: "The total exterior lighting power allowance for all exterior building applications is the sum of the base site allowance plus the individual allowances for areas that are designed to be illuminated and are permitted in Table 1 for the applicable lighting zone. Trade-offs are allowed only among exterior lighting applications listed in the "Tradable Surfaces" section of Table 1."
