Mercy West Hospital
Cincinnati, OH, USA

109,600 sq. ft Greenroof


Project Description & Details

Mercy Health Partners has created a new hospital on a 65 acre site located in Green Township on the west side of Cincinnati, Ohio. The sustainable site plan features low energy LED site lighting, a prairie, bioretention areas, and thousands of native plants. A 2.5 acre green roof is located above mechanical and surgical rooms and two patient towers rise four stories above the green roof offering healing views for patients and visitors.

The green roof is primarily an extensive green roof planted with a mixture of 50,000 sedum plants of four varieties. Swirling across the green roof are intensive berms that mound to 30” high on which larger grasses and perennials grow recalling the rolling hills of Ohio’s ancient prairies. Prairie grasses number 1,300 plants and they include Little Bluestem and Prairie Dropseed. Over 12,500 perennials were installed including Allium, Milkweed, Pinks, Rudbeckia, Monarda, Liatris, and Obedient Plant. These perennials bloom for a number of weeks from spring to early fall and display a range of colors from white, yellow and orange to pink, red, and purple.
