Gensler’s design at the University of Houston is realized in a cloud-inspired, sound-absorptive ceiling solution.
Gensler and Ceilings Plus have brought a touch of the Big Apple to the University of Houston’s recently completed Quiet Hall in the Classroom and Business Building. Gensler drew its design inspiration for a ceiling in the new building from the New York Central Library’s Rose Reading Room. The firm hired the California-based Ceilings Plus to translate its interpretation of this classical interior, which includes perforations and geometric folds, into an affordable, buildable, and installable ceiling solution.
Ceilings Plus used digital software to marry the design architect’s vision with a workable model that offered minimal joint tolerances and maintained compatibility with HVAC systems. “Since the architect was interested in doing something completely new, it was important to realize that process together,” said Michael Chusid, who works in marketing and business development for Ceilings Plus. Gensler produced three conceptual renderings in Revit, then turned them over to project engineer Robert Wochner, who developed sound-absorptive perforations and a suspension system that could support the various angles of the Quiet Hall’s multi-planar ceiling.
Wochner used AutoCAD to reconcile Gensler’s rendering, which depicted a cloud of perforations across the ceiling for sound absorption. Acoustically there was an ineffective number of apertures, so Wochner filled in the original design with smaller, carefully angled perforations. By leaving an ample amount of space between the dropped ceiling and the planchement, the perforations are able to absorb vibrations in an efficient and lightweight system. Nearly 50 configurations were considered before arriving at a final design, which was modeled in SolidWorks.
Ceilings Plus fabricated the panels using stock products and a CNC router. The architect’s chose the company’s PVC-free Saranté laminate in a henna-toned wood finish, which is affixed to an aluminum sheet. A punch press knocked out the perforations, revealing a blue felt backing.
Despite the ceiling’s complex appearance, Ceilings Plus developed a suspension system based on a conventional T-bar system, making it easy to install. Since the ceiling is not flat, attachment points were individually set to hang each of the 280 panels from between six and eight torsion springs. “With this firm pressure downward, you can extract the panel and lower it out of place to gain access to the ceiling cavity to maintain the HVAC system, ductwork, and other mechanicals,” said Chusid. Custom-fabricated brackets help support the unique angles.
Ceilings Plus deployed several expert installers to assist the installation process. “Any time there’s a slope on the ceiling and it interfaces with something round, like a column, it goes from a circle to an ellipse,” said Wochner. “Though we have precise information about the field location, it’s not uncommon to make adjustments on site.”
