The Bluffs at Playa Vista Parking Structure–Saving Water by Greening the Scenery
The Bluffs at Playa Vista, a creative office space in Los Angeles, California, stands as a prime example of sustainable architectural design, achieving LEED Gold Certification for its commitment to energy efficiency and water conservation. A key feature of this development is the innovative use of green walls on two adjacent cast-in-place concrete parking structures, covering more than 15,200 square feet. These green walls, installed between 2008 and 2010, were envisioned by Scott Johnson, FAIA, and Jed Donaldson, AIA, of Johnson Fain Architects. Their design concept involved the strategic placement of Greenscreen® trellis panels, a three-dimensional welded wire system, populated with vibrant royal trumpet vines.
The project's commitment to water conservation is particularly noteworthy, utilizing 100% recycled water for all landscaping, including the extensive green walls. This initiative aligns with the pressing need for water-wise design in California, a state frequently grappling with drought conditions and unpredictable weather patterns. The Greenscreen® trellis system, chosen for its aesthetic appeal both with and without vegetation, proved to be a functional choice. The three-dimensional quality of the system was favored over flatter alternatives, providing shade, cooling ambient temperatures, and slowing stormwater runoff by capturing rain on leaves and in soil beds. While heavier watering is initially required for the establishment of trumpet vines, typically two years, the water demand decreases significantly as the plants mature.
Johnson Fain Architects collaborated closely with Greenscreen® to ensure the precise fabrication and installation of the trellis panels. Detailed shop drawings were crucial for field verification, ensuring that the 4-foot-wide panels, of varying lengths, were accurately manufactured with factory-welded edge trim. This trim creates a clean frame around each panel grouping, enhancing the overall aesthetic. The installation process involved attaching the panels strategically to the bare concrete walls, spanning multi-story parking spandrels to create engaging and playful dimensional patterns. An additional west-facing section of panels was installed in 2009, all of the same size and hung horizontally, which simplified installation and reduced lead time. Standard adjustable clips, specifically the 5132A (now 5132R), were used to mount the panels, allowing for space between the panel back and the wall surface. This small air gap facilitates regular maintenance of the green facades.
The landscaping at The Bluffs was designed by the international collective RIOS, further supporting Playa Vista’s water conservation goals. This design incorporates native ornamental grasses, vibrant plants, succulents, native trees, and the drought-tolerant royal trumpet vines. Beyond water conservation, this vertical greenery serves multiple ecological functions: attracting pollinators, supporting biodiversity, and softening the harsh, hot concrete surfaces typically associated with parking structures. The project's longevity, demonstrating the continued functionality of the Greenscreen® panels over 14 years, showcases the enduring benefits of integrating sustainable practices into architectural design, providing both aesthetic and biophilic advantages to the community and contributing to the visual appeal along Campus Center Drive in Playa Vista.
