The backlit escalator wall installation at the Grand Hyatt in San Francisco is wrapping up smoothly.
Here's the project rendering again, described in our first blog post about this project:
Some photographs snapped from our cell phones in the field:
The clean lines and even illumination are the result of months of iterative detailing and expert installation. A great project for our team to celebrate this weekend!
If you missed our first blog post about GPI technicians arriving on-site for this long awaited backlighting installation at the Grand Hyatt San Francisco, check it out here (and take a peek at the project rendering).
After a labor-intensive weekend, the bottom and center rows of the custom-built 3Form Varia Ecoresin and wood slatted surface panels are now illuminated.
To ensure that the intense patterning of wood and light was not further disrupted by structural shadows and inconsistent lighting, the fastening system has been considered hand-in-hand with the backlighting system design from the earliest concept stage.
Blocking on the back of the 3Form/wood surface panels not only reinforces the eight foot panels, but also provides a channel to hold the Flat-Lite™ at the correct distance from the lens. The combination of burying powered LED edges into the blocking and employing diffusing tapes ensures that hot spots are not visible from any viewing angle of the feature walls.
Notice the trapezoidal panel shapes along the bottom course of panels? With special attention to light collection in the acute corners,the LED light panels were custom designed with controls and filters to provide even illumination.
More photographs of the entire completed feature wall coming soon as this installation wraps up!
For the extensive renovation of the San Francisco Grand Hyatt in Union Square, the teams at Indidesign (interior design) and Revolver (lighting design) envisioned a custom panel and backlighting treatment to revive the wall surfaces at the main escalator.
Extending from the lower lobby to the main lobby, dark wood panels striated with thin lines of illuminated 3Form Varia Ecoresin clad the escalator walls. The custom-built backlit panels bring innovative light, interesting texture, and a unique pattern as viewers move throughout the levels of the hotel.

The team here at GPI has worked on the project for over 6 months, coordinating closely with the millwork team at Acosta & Sons to merge our backlighting solutions with their custom wood and resin panels. Flexibility has been key in the project, as field dimensions shift, so have our strategies, LED panel sizes, fastening devices, and methods of controlling and balancing the light. (Special thanks to Cliff at Acosta & Sons for hand-delivering the 3Form panels on a redeye from California to Ohio so we could test the lighting!)
The custom components (Flat-Lite™ LED panels, Infuse™ custom lighting controls, wiring, and diffuser panels) arrived to site on August 1. Shortly thereafter, GPI lighting technicians arrived on-site to assist with the time-sensitive installation.

We enjoy being on-site to finally witness these intense coordination efforts come to fruition. Stay tuned for more photos and updates as this project progresses - we’ll share more about the process of generating the LED panel design, how the custom wood /resin panels were created, and how shadows and hot spots were eliminated.
