D et ete rm rmi ne ne th the interior lighting power allowance by using the columns designated Space-by-Space Method in Table 9.6.1. Multiply the floor area(s) of the space(s) times the allowed LPD for the space type that most closely represents the proposed use of the space(s). The product produc t is the lighting power allowance for the space(s). For space types not listed, selection of a reasonable equivalent equivalent category shall be permitted. d. The interior lighting power allowance is the sum of lighting power allowances of all spaces. Trade-offs among spaces are permitted provided that the total installed inte does not exceed the interior lighting rior lighting power does power allowance. 9.6.2 9.6.2 Additio Additional nal Inter Interior ior Lighti Lighting ng Power Power.. When using the Space-by-Space Method, an increase in the interior lighting power allowance is allowed for specific lighting functions. Additional power shall be allowed only if the s pecified pecified lighting is installed and automatically controlled, separately from the general lighting, to be turned off during no nbusiness hours. This additional power shall be used only for the specified luminaires and shall not be used for any other purpose. An increase in the interior lighting power allowance is i s permitted in the fo llowing ca ses: a.
For space spacess in which which lighti lighting ng is speci specifie fied d to be instal installed led in in addition to the general lighting for the purpose of decorative appearance, such as chandelier-type luminaries or sconces or for highlighting art or exhibits, provided that the additional lighting power shall not exceed 10.8 W/m2 of such spaces.
