Federal Express proposed to construct solar photovoltaic (PV) systems on three buildings it owns and operates at Newark Liberty International Airport. The combined capacity of the projects is about 2.2 MW.
FedEx's contractor, Ray Angelini Inc., engaged HMMH to prepare a reflectivity study of the project to assess the potential effects of glare on sensitive airport receptors, including the air traffic control tower and arriving aircraft. HMMH utilized its in-house proprietary Java-based modeling tool to predict reflections based on project design and the path of the sun throughout the year. The model conducts millions of calculations of straight line reflection from the sun's position off the panels. It visually displays the appearance of the reflection and generates data to further analyze when the glare is occurring and from which parts of the solar project.
The reflectivity study has been used by the project team to enhance the project design. It will also be submitted to the FAA as part of its Form 7460 Airspace Review of the project.
