Project of the Month | Intrepid Sea-Air-Space Museum

Located on the west side of Manhattan along the Hudson River at Pier 86, the Intrepid Sea-Air-Space Museum reopened to the public in November 2008 after an extensive two year renovation. The exterior areas of the museum were completely redesigned to provide a welcoming park-like atmosphere and an inviting oasis for visitors. The permanent home to the aircraft carrier, USS Intrepid, features Village catenary and Canto pole mounted fixtures in key areas of the site and is the latest project of the month.

Village catenary luminaires installed under fabric sail structures help greet the estimated 750,000 visitors per year as they arrive at the entrance to the museum. The luminaires are suspended by stainless steel cables and fittings mounted to poles, which also support the fabric sails. Due to the forces generated by the loading of the luminaires and sails, a large diameter pole was required to support the assemblies.

Pole mounted Canto luminaires line the right side of Pier 86 opposite the USS Intrepid. Lamped with 250w metal halide, they illuminate the promenade for evening shows and events.

2009 IESNA Progress Report

We are pleased to announce two HessAmerica products were selected for inclusion in the IESNA 2009 Progress Report. The products chosen include the LINEA LED bollard and the SERA LED pole mounted luminaires and were selected by a jury on the basis of their uniqueness and significance to advancement to the art and science of lighting.
For additional product information on these products, please click on the links below.

Product Focus - SERA LED

One of the unique aspects of the new SERA LED fixture is its field changeable light engine module. Equipped with an electrical quick disconnect, it can easily be replaced by removing three screws, giving the owner the ability to upgrade the LED light engine as technology advances. As with the HID models, tool-less access to the sealed optical compartment is accomplished by the formed aluminum door latch, which fits flush to the housing when closed.
The field changeable LED module accommodates advances in technology without replacing the luminaire.
Photometrically, the SERA uses two high-power LEDs producing 1380 delivered lumens while consuming only 39 total system watts. Light is reflected by the spun aluminum reflector, and then shaped by the specially designed prismatic lens to produce a uniform asymmetric light pattern. The distribution is long and narrow and suitable for sidewalks and pathways, as well as corporate and college campus streetlighting. Prisms on the interior of the lens mitigate the visual brightness commonly associated with LED pole mounted products, while the smooth exterior surface minimizes dirt accumulation. Spacings of 60' on center are possible when using the standard 15' pole height.
Special prismatic lens minimizes visual brightness while producing a uniform asymmetric distribution pattern.
SERA LED emits zero uplight above ninety degrees and can be used for LEED lighting zones LZ2 through LZ4. Color temperature is 5600K. Mounting configurations include a direct to post-top model and a choice of decorative brackets, as well as a wall mount model for expanded design possibilities.

Architectural Record - 2009 Product Reports

The LINEA LED bollard was one of four lighting products selected for inclusion in the annual Architectural Record 2009 Product Reports issue. The eight-person jury consisting of seasoned design professionals made lighting product selections based on the importance of performance, scale, detail, and relevance of LEDs in lighting products. HessAmerica is proud to have been one of the few chosen from the numerous entries received. To see the LINEA product write-up, go to page 165 of the December 2009 issue of Architectural Record.

LEED 2009 For New Construction and Major Renovations

Sustainable Site Credit 8: Light Pollution Reduction Revisited

The LEED 2009 rating system for New Construction and Major Renovations went into effect in July. It is a welcome update to the previous version, providing clear language on uplight percentage limits for each of the lighting zone classifications. Previously, specifiers, through no fault of their own, often misinterpreted the language, and limited their fixture selections as a result. Further, lighting manufacturers added to the confusion by publishing LZ ratings for their outdoor lighting products.
The key point in the updated language is the LZ classification of the project specifies the overall percentage of allowable uplight emitted by all of the fixtures on the site (cumulative), not the uplight percentage of an individual fixture. This gives specifiers the latitude to incorporate a broader selection of luminaire styles in feature spaces that may not have been considered due to confusion caused by the wording of the previous version.
The following excerpts detail the allowable uplight percentages for each LZ zone. HessAmerica products will likely be specified for projects designated as LZ2 through LZ4.
LZ4: High (high activity commercial districts in major metropolitan areas)
  • Document that no more than 10% of the total initial designed fixture lumens (sum total of all fixtures on site) are emitted at an angle of 90 degrees or higher from nadir (straight down).
LZ3: Medium (all other areas not included in LZ1, LZ2, and LZ4 such as commercial / industrial, and high-density residential)
  • Document that no more than 5% of the total initial designed fixture lumens (sum total of all fixtures on site) are emitted at an angle of 90 degrees or higher from nadir (straight down)
LZ2: Low (primarily residential zones, neighborhood business districts, light industrial areas with limited nighttime use and residential mixed-use areas)
  • Document that no more than 2% of the total initial designed fixture lumens (sum total of all fixtures on site) are emitted at an angle of 90 degrees or higher from nadir (straight down).
LZ1: Dark (developed areas within national parks, state parks, forest land, and rural areas)
  • Document that 0% of the total initial designed fixture lumens (sum total of all fixtures on site) are emitted at an angle of 90 degrees or higher from nadir (straight down).
The following example illustrates how an application using (6) LINEA 600 luminaires with 150w ceramic metal halide and (2) RENO columns with 70w ceramic metal halide will meet the uplight requirements for LZ2, which has a 2% total site uplight limitation.
