The lighting design provides a stunning first look to the
building as the ceiling surface glows brightly and enhances the strong
architectural features. The lighting is
an extremely energy efficient solution which utilizes the glass curtain walls
in conjunction with daylight harvesting ballasts and photocells to allow the fixtures
to produce only as much light as required.
This system balances a consistent light level on the work surface at all
times of day and throughout all seasons.
The pre-cast concrete vaults presented the largest
challenge because they require even illumination and they need to provide the
practical light for the workplace. A series of standard fixtures were explored
to meet the design needs and nothing “off the shelf” fit the bill.
Custom indirect/direct fixtures were created to precisely
run the length of the linear vaults while following the interior curves of the
space. T5 (3’) or (4’) standard output 3500k fluorescent lamps are used to keep
the lumen output consistent down the runs.
The fixtures produces indirect lighting to fill the vaults with light
which the ceilings then direct the bounce light down to the work surface and
circulation areas.
The fixtures incorporate a square pattern design to
provide visual interest, a harmonious design, and downlight accents to give the
appearance of a layered approach.
At the front of the building sits the glass enclosed
feature staircase. Pendant 39w metal halide
fixtures hang down below the open cell ceiling grid to give a strong punch of
light on the stair treads down the double height space. They were chosen for their high tech industrial
design and energy efficiency.
The entire space uses roughly half the energy of the
ashrea 900.1 -1999 standard code, while still filling the space as a light
beacon to Loyola’s campus.
