Use this dialog to check the power usage of exterior lighting. The first 3 columns of the grid may be edited to enter the required data. The data is automatically validated against the interior lighting load for the Proposed model (which is as Actual by default). This check is in accordance to the SS530 limits on exterior lighting. The floodlight for the façade should be lower than 5% of the proposed interior lighting power density, and the other uses (for exterior lighting) should be kept below 5W/m2.
