DAYTON — Miami Valley Hospital has been awarded LEED Silver certification for its 12-story, $135 million patient tower, according to a news release.

The hospital said it is the first hospital in southwest Ohio to receive such certification.

To receive the certification for the 178-bed building, the hospital:

• through its construction team diverted more than 75 percent of the building’s demolition and land-clearing debris from disposal in landfills and incinerators.

• reduced energy use by 18 percent through the use of high-efficiency mechanical and lighting systems.

• used building materials such as structural steel, aluminum, fabrics and flooring that was more than 35 percent recycled.

• reduced water use within the building by more than 20 percent and water use for landscaping by 60 percent.

The hospital also planted green roofs, which include 11,000 square feet of living plants. Such roofs are meant to cut stormwater run-off and insulate the building, thereby cutting heating and cooling costs.

The patient tower opened in late December.

LEED stands for Leadership in Energy and Environmental Design and is a well-known certification in the “green” construction industry. LEED certification is made on the following scale: Certified (40-49 points); Silver (50-59 points); Gold (60-79 points); Platinum (80 or more points).
