Ken Saiki Design worked closely with Engberg Anderson Architects and staff at the University of Wisconsin-Madison to design a cohesive new suite-style residence hall and food service facility in the Lakeshore Neighborhood. Ken Saiki Design played a leading role in designing the 28,362 square foot extensive green roof which included decorative stone ballast, precast concrete pavers and diverse plantings with growing media depths that ranged from 6-inches to 8-inches.
The design team approached the design of the green roof by dividing the plantable area into five zones based on the growing media depth, sun/shade aspect and desired aesthetic. A custom list of sedum and perennial species was then developed for each of the five zones based on the specific challenges of each microclimate. Pre-grown sedum mats were delivered to the site, rolled out and anchored in place while perennials were carefully laid out and planted through the sedum mats and into the growing media below. The 22,275 square feet of sedum mats form the backbone of the green roof’s planting design while the perennial plants add texture, color and height variation.
The green roof is visually accessible from interior conference rooms and resident living spaces. The successful project is yet another example of the University’s commitment to sustainability and desire to provide meaningful connection between campus living and the core values of the institution.
