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 />
