FOREWORD

This addendum makes three changes to Normative Appendix G.

a. It ensures that lighting power is determined using the same approach (Building Area Method versus Space-by-Space Method) for situations where a lighting system neither exists nor has been designed. It requires that both proposed and baseline lighting power be determined according to the Space-by-Space Method if space types are known, and according to the Building Area Method if they are not.

b. It ensures that the impact of exceeding the power limits for exterior lighting of nontradable surfaces is captured by requiring that the baseline building lighting power be the same as the proposed, or equal to the baseline defaults, whichever is less.

c. A baseline allowance is added for retail display lighting that is equal to the proposed design.

This addendum impacts an optional performance path in the standard designed to provide increased flexibility and therefore was not subjected to cost effectiveness analysis.

Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and strikethrough  (for deletions) unless the instructions specifically mention some other means of indicating the changes.
