NOTES ON LIGHTING DESIGN<br />

Appealing Lighting<br />

A symbolic environment, which reflects the scales of truth and justice,<br />

can seem intimidating to some, but can also be a sanctuary of comfort<br />

to others. Whether working or simply visiting, one cannot ignore the stunning<br />

uniqueness of the Federal Courthouse located in Brownsville, Texas.<br />

In taking on a project of such magnitude, Bos Lighting Design was forced to consider the monumental look necessary for a<br />

building of this kind, while still attempting to deliver the concept of a warm, gracious public space environment.<br />

“The architects expressed a desire for the building to be revealed at night as a testament to its importance as a Federal<br />

Courthouse, but at the same time, we wanted to keep the look from becoming too institutional, cold, impersonal and<br />

uncomfortable,” said Designers John Bos and Becky Bowen of Bos<br />

Lighting Design.<br />

The difficulty of this project was increased by the stringent energy,<br />

maintenance, and budget requirements that come with any federal project.<br />

In terms of maintenance, attention was paid to lamp life, and there<br />

was an attempt to standardize lamp types as much as possible, including<br />

beam spread and color temperature.<br />

“While the budget was a factor for the exterior lighting, what was more<br />

of a guiding factor was that the luminaires be of high quality,” said Bos<br />

and Bowen, “particularly when dealing with in-ground and other luminaires<br />

that are exposed to the extreme Texas weather and the high<br />

pedestrian traffic.”<br />

What was most cost-effective for the project was the installation<br />

quality of the luminaires, which would hold up for years to come.<br />

Hydrel luminaires were chosen for its value and its track record for<br />

holding up over time, and — as a bonus — it was not the most expensive<br />

line on the market.<br />

Uplighting was used throughout the exterior to emphasize vertical elements<br />

and to lift the eye upward. These color-corrected metal halide<br />

adjustable upliftings create a sense of grandeur. In contrast, low-glare<br />

bollards were selected to illuminate pedestrian pathways and guide foot<br />

traffic. A variety of light was also chosen to highlight built forms and different<br />

shades of foliage. Lavender filters were used to enhance the cool<br />

greens of the shrubbery, while straw/pale gold filters were used to<br />

uplight the palm trees, bringing out the warmth in the trunks and the<br />

green tones of the palm leaves.<br />

Given the nature of the building, there were concerns about on-site<br />

security. Bos Lighting Design illuminated the landscape and exterior<br />

architectural elements. Such areas included the benches, which have a<br />

step light underneath; the front columns that support the metal canopy in front, which act as a natural place for uplighting, and<br />

the colonnade walkways to the parking areas. Cut-off luminaires were also used in the parking areas, specifically, to not create<br />

light trespass, since Brownsville is still small and dark enough for evening stargazing.<br />

“With all the uplighting, it was important to control<br />

glare, which can be blinding, thus making it as much of a<br />

security issue as a lack of light,” Bos and Bowen said.<br />

To avoid this problem, well-shielded fixtures were chosen<br />

(with the lamp deeply recessed) and additional louvers/glare<br />

guards were added wherever necessary. Full<br />

shielded bollards were used to directly light the main<br />

pedestrian pathways into the building to highlight the area<br />

safely and without any glare.<br />

As both a civic landmark and a federally funded project,<br />

the Brownsville Courthouse required thoughtful design<br />

integrated with energy- and maintenance-sensitive lighting.<br />

By using color corrected metal halide and fluorescent<br />

sources to highlight the built forms and landscape elements,<br />

all of these objectives were thoroughly met<br />

throughout the project.<br />
