LiveWall Green Wall Installation Adds a Living Element of Green Design to the Monroe County Parking Garage in Bloomington, Indiana

When you think of parking garage design and construction, what descriptive words come to mind? Bland, austere?
Monroe County in Bloomington, Indiana constructed a six-story, 240-space parking garage for its employees in 2017. Their new parking garage is surprisingly different. A LiveWall® living wall fills five of its window openings with a variety of seven different annuals that bloom in shades of yellow, red, pink, purple, and green.
“The idea was to break up the otherwise stark exterior of the structure with an interesting and visually appealing element achieved by incorporating some green design,” said Stephen Andoh, AIA, LEED AP, project manager, Axis Architecture + Interiors, the project architect.
Many nearby buildings have second and third story window boxes with flowers. “Installing a total of 180 LiveWall modular planter boxes was like putting window boxes into the window openings of the garage,” said Julie L. Thomas, Monroe County commissioner. “The five sections of green wall make a lovely, lively addition to the exterior.”
Green Wall Installation
“LiveWall was a good choice for an outside green wall exposed to the elements. Its components and parts are strong and durable,” said Joel Fleming, project manager, Hagerman Construction Corporation, the project’s general contractor.
“LiveWall’s structural design lent itself to a secure installation within the garage windows in a way that allows for easy access from behind the green wall inside the garage for maintenance or changing out plants,” said Logan Messmer, project engineer, ProCLAD, Inc., a building envelope contractor selected to install the parking garage living wall.
The LiveWall outdoor system establishes a vertical garden mounted on exterior walls. In the typical outdoor installation, the system’s vertical furring tracks are attached directly onto the surface of a wall. Horizontal aluminum rails, which include conduits to bring water to the outdoor system’s integrated irrigation sprayers, are bolted to the tracks. LiveWall modular planter boxes, which are high-impact, UV-resistant, architectural quality moldings, slide into the rails along a specially designed slot. Finally, separate liner inserts, which are removable and reusable plant containers that hold the growing medium and pre-grown nursery plants, drop into the planter boxes.
However, in this application the system was not mounted on a solid wall surface. The parking garage living wall had to be installed across window openings within the structure’s wall.
“We had previous experience installing trellis systems that grow vines up the side of a wall from the ground up,” said Messmer. “This was different because there is more substantial structure to support the modular planters and irrigation components.”
After LiveWall gave our project managers and engineers a 30-minute installation tutorial, it was not hard to figure what we needed: a frame within the windows to which we could secure the horizontal rails.”
The window openings in the parking garage measure 8 feet long by 6 feet tall. Each of the five sections of green wall has six rows of LiveWall modular planter boxes that cover the openings. ProCLAD designed and installed a metal framework within the window openings with 4-inch by 4-inch by ¼-inch tube steel. They bolted the LiveWall system’s horizontal aluminum rails to the tube steel frames. The modular planter boxes were then slid into the rails’ slots.
“The integrity of the system underwent a challenging test the day the plants went in,” said Thomas. “We had a huge, powerful thunderstorm with intense rain, wind and hail. The green wall and plants came through fine.”
Thomas and her colleagues initially thought of using perennial plants. LiveWall suggested they might consider annuals.
“Perennials or annuals can both work. The selection of annuals for living walls is much more varied and colorful, and they only require maintenance during the growing season,” said Dave MacKenzie, horticulturalist and president of LiveWall. “Annual bedding plants are also generally less expensive than perennials. Using annuals gives you more flexibility to try different plants and change the appearance of a living wall from year to year.”
On the Monroe County parking garage installation, the sections in the top, the third and the bottom of the five windows feature alternating columns of Yellow-, Red- and Purple-leaved Coleus plants. Their distinctive foliage colors stand out, and they bloom with light purple flowers in the summer and fall. The bottom rows of modular planters in these three window sections are planted with Dichondra argentea (Silver Falls). Clusters of their small, silver-green leaves trail down from the planters. The second and fourth windows feature alternating mixes of Red and Pink Begonias, which bloom abundantly from summer through the first frost. Deep purple Sweet Potato Vines (Ipomea batatus) trail from the bottom row of these windows.
Results and a Surprise
“The living wall is stunning, eye-catching, and appealing,” said Andoh.
Commissioner Thomas has received text messages, emails and comments from county officials and employees, the general public, and her constituents. They have all been positive — rare for a county project, she noted.
There was one surprise. Thomas did expect the green wall to be beautiful. “What I did not anticipate is the captivating effect of the wind moving through the leaves and flowers of the plants. A light breeze can make the living wall come alive.”
