Tunnel vision

It was announced last week that the fluorescent lamps in New York’s famed Holland Tunnel will be replaced with LED lamps. About 32,000 running feet (6.4 Miles) of new linear LED lamps will be installed. The project will be finished this coming fall.

The new LED lighting will help to achieve $250,000 a year in energy savings and significant savings in maintenance costs. In addition, it will bring the interior tunnel illumination level up to IESNA RP-22 requirements. The project started in 2009, went through numerous challenges, and is now coming to a successful completion.

AWA’s Scope

AWA worked in close collaboration with the client and On-Board Engineering on this project. For this project, AWA was responsible for:

· Developing design and performance specifications for LED fixtures

· Providing a detailed LED technology and material review for tunnel and infrastructure lighting

· Analyzing LED systems for retrofitting current fluorescent system

· Evaluating submittals from manufacturers and provide recommendations to client

· Analyzing and evaluating prototype of fixtures to ensure conformance to specifications

AWA reviewed and evaluated 11 manufacturers that could provide linear IP-66 rated LED fixtures for this application. The design specifications were developed for usefulness for the next 15 years. The fixtures are future proofed for easy access/replacements of lamps over this period.
