Hello, I am working for a Retail-commercial interiors project with less than 5000 Sq feet of space. In order that the project verifies the performance requirements of Section 9 of ASHRAE 90.1-2007, I am using the space by space method for Lighting power densities.

Can I take the Trial room space of the Retail joint as Mall Concourse area with 1.7 W/square feet ?
