The renovated building that houses Green Street Academy in Baltimore has received LEED Platinum certification for its energy efficiency and sustainable design.

WJZ-TV reports that the academy is the only school in Baltimore and in the state of Maryland that has received the platinum designation, the highest certification level bestowed by the U.S. Green Building Council.

The academy is a charter middle and high school with about 750 students. It was founded in 2010 and moved last year to a 1925 building that once housed Gwynns Falls High School. That school closed in the 1980s.

Before Green Street was ready for classes in the facility, it underwent a $23 million renovation that emphasized sustainability and environmental sensitivity.

Sustainable elements include solar panels, a vegetable garden, an aquaponics green house, water-filling stations daylight and motion sensors are just some of the features of the energy saving design.

The renovation also reused walls, floors and roofs, as well as recycled materials, according to the website.
