The future of folding glass walls is here (and before long, everywhere)
The Saint Francis Central Coast Catholic High School, which opened in 2002, needed to be designed in a way that would be appropriate to the pedagogical method set forth by the Order of St. John Bosco. WRNS Studio, the firm tasked with designing the project, set about programming a space that would make the best use of the spectacular countryside views while embracing a central tenet of the Salesian student-teacher relationship: transparency.
"The project called for an art classroom that utilized an outdoor patio for teaching space," recalls Adam Woltag, AIA, LEED AP, project designer for St. Francis. The project also called for a high level of sustainability. Ultimately, the firm elected to install NanaWall's SL70 Thermally Broken Aluminum Framed Folding System, which now represents a major portion of one of the walls of the high school's arts and sciences center.
Passive Energy Strategy
Not only does the NanaWall folding system support the concept of transparency among scholars with literal transparency — as do many of the design's interior walls, providing visual connections among separate spaces — but the thermally high-performing wall adds significantly to the passive energy strategy integrated into the facility. The SL70 offers contributions to the natural daylight, heat gain control and natural ventilation components of this strategy.
"The St. Francis Central Coast Catholic High School Arts and Sciences Center provided our first opportunity to use a NanaWall system," continues Woltag. "NanaWall gave our builder a system that was easy to install and gave our client a system that students and teachers love to use.”
As for Specifying NanaWall Rather Than Another Product, Woltag Explains, "All Other Window Wall Systems We Considered Were Complicated, Inflexible and Did not Support Our Design Goal."
Located in Watsonville, California, a town in Santa Cruz County known primarily for agriculture, Saint Francis Central Coast High occupies a beautiful farm site nestled among low-lying mountains. With rich vistas available, the necessity of transparency in the school design became even more compelling from an aesthetic standpoint.
To deliver the proper passive energy strategy, the design called for heavy block walls on the south and west sides, and near complete transparency for the north and east elevations. NanaWall's contribution to the art studio enclosure serves as a large portion of this transparency.
As for specifying NanaWall rather than another product, Woltag explains, "All other window wall systems we considered were complicated, inflexible and did not support our design goal of an integrated window wall that completely opened to the outdoors."
Performance When Closed
Teachers and students have the opportunity to occupy the patio beyond the NanaWall folding system, or enjoy an open wall room for study, with fresh air and views for inspiration. And in inclement weather, or during the colder months, the wall is still almost entirely transparent, making the views available still.
The thermally broken NanaWall design provides a high level of insulative value, as well, helping the high school to achieve its current status as a model of sustainable, passive-energy design.
What our Customers Have to Say
Spring Valley Academy’s New Worship Center
The founders of Spring Valley Academy were determined to produce an event center that would be the crown jewel of the school. Learn how a NanaWall SL70 made the Fritzsche Center for Worship and the Performing Arts shine.
With the intent of blurring the lines between inside and out at this New England residence, NanaWall was the chosen solution because of the system’s engineering and aesthetic advantages, including the Screen Classic option.
“This flexibility allows teachers to gain access to shared resources and adapt space for small and large groups as well as project-based learning activities.”
