If the "Total base lumens" is showing as a FAIL but the "total lumens" is a PASS, there are too many lumens used for a Base application. Left over
lumens from an additional application do not contribute to the base allowance.

How to use this calculator:
1) Enter the applicable Zone District in which your project is located. The identification of the apllicable Zone District informs the compliance form to
apply the applicable Lighting Zone and the corresponding criteria.
2) Enter your maximum calculated light trespass illuminance values. Calculation points should be spaced at no more than ten (10) ft, located at the
ground level and aimed at the zenith.
3) Select a lumen allowance method. Note that the parking space method is only applicable for properties with up to ten (10) parking spaces.
4) If using the hardscape method, up to two applicable additional allowance applications may be selected. Input the quantity of the corresponding unit
area or number of pumps.
5) Fill out the each of the luminaire types used on the project, with the initial lumen output, quantity, CCT specified, mounting height above finished
grade, BUG ratings, as well as the closest distance to the property line of that specific luminaire type. If the luminaire type has installations aimed both
towards and away from the property line, test both scenarios to ensure compliance.
6) If the specified luminaire type is used for an Additional Allowance Application, specify the application. If the application is for "Outdoor Sales Lots" or
"Outdoor Dining", specify the maximum distance to the specified area of that luminaire type. If an application that was not selected in step four (4) is
selected that cell will turn RED.
NOTES:
a) Cells with an ORANGE fill are inputs.
b) Cells with a dark BLUE border are required inputs.
c) Cells that are GREY have formulas that are proccessing information from inputs. DO NOT change these cells.
d) If a cell turns RED it does not meet criteria.
e) If a cell turns GREEN it passes criteria.
