Dear All,

We are working on a shopping mall project which is pursuing LEED for C&S certification. According to table 9.6.1, maximum lighting power density for retail store is 18 W/sqm plus accent lighting. Since we don´t know which type of sales area is going to use the retail store, can we model the lighting power density considering "Sales Area Type 3" allowance according to table 9.6.2.? We would like to consider 44 W/sqm (Retail Sales Area 18 W/sqm + 26 W/sqm). Such lighting power density is close of what will be available for the tenants for interior lighting. Since there is not lighting design for tenant areas, we are going to use same allowance for baseline and proposed case.

Best Regards.
