The school facilities department was asked to improve visitor experience in their multi-usage garage that is mostly used by student, teachers and parents for daily school classes, activities, and special sports events. The goal of the project was to maximize the sense of security on site, while lowering the impact the parking garage lighting had on neighbors, and do accomplish this without raising electricity cost.
Most parking garages require 24-hour lighting, 7 days a week, which leads to high energy costs. The team decided to look at adaptive lighting solutions and started by evaluating a motion sensor solution that would be embedded in parking garage luminaires, commonly referred to as a stand-alone, which provides additional energy saving to LED lighting technology. They soon realized the solution had significant drawbacks. For example, when activity is detected, the light is increased to the maximum level only for a location to close proximity where the activity was detected and kept it at a maximum level for a long period of time, sometimes up to 15 minutes. To change such behavior some solutions require changes to each luminaire, one at the time, which was time consuming.
Shortly after that solution was tested, a network systems solution was considered but many of the options available were too complex to implement and in the long term would not be easy to maintain. Plus, many cyber security related concerns were raised by the team to those networked and cloud-based solution manufacturers, and he did not return a suitable answers that made the team feel comfortable moving forward with the solutions.
