I believe there is an error in the Sample LPD Calculation file that has been provided. Or, my understanding how to correctly calculate the LPD is wrong. For Walkways 1, there are two fixture types (Pole Fixture 2 and Bollard Fixture 1). The total fixture power for each fixture type is divided separately by Walkways 1 Site Area. This results in 0.13 W/SF for Pole Fixture 2 and 0.18 W/SF for Bollard Fixture 1. Then, to calculate the Actual LPD for Walkways 1, 0.13 and 0.18 are added together then divided by 2, resulting in an Acutal LPD of 0.16 for Walkways 1. This does not seem correct. Shouldn't the Total Fixture Power for Pole Fixture 2 (115 Watts) be added to the Total Fixture Power for Bollard Fixture 1 (160 Watts) resulting in a Total Fixture Power of 275 Watts for the Site Location Walkways 1? Then 275 Watts should be divided by the Site Area of Walkways 1 (875 SF) resulting in an Actual LPD of 0.31. Which method is correct? Also, the Area for Walkways 1 is listed as 1,500 SF. This number does not coincide with any other areas listed for Walkways 1.
