Challenge
In order to not disrupt the court’s business, we focused on only one courtroom at a time, scheduling work for holidays and weekends, allowing judges and other agencies in the building to maintain their planned court schedules. To reach the cupola lighting, we built, disassembled, and rebuilt a 30’ scaffolding in each courtroom
Our Solution
The project was delivered on time, within budget, and caused no unforeseen problems during the installation process. GreenGen performed the following:
Conducted an on-site survey and Investment Grade Audit of lighting at the courthouse; coordinated with facility engineers and city administrators
Reviewed the proposed lighting spectrum content with the US Marshalls and Federal Protective Services to ensure infrared lighting levels were sufficient for surveillance camera operation
Engineered site-specific photometric plans in conjunction with courthouse on-site personnel and GSA requirements for energy efficient LED lighting upgrades
Designed and provided demonstration of decorative lighting solutions before installing the approved design
Used the GreenGen secured rebates to upgrade the 44 utility room fixtures to LED tubes
