BRUNSWICK — Bowdoin College says it has a cool new rooftop for its heating plant.

The college says planting materials for the Brunswick campus’ first living, or “green,” roof arrived Tuesday. They were hoisted to the top of the building that houses the college’s high-efficiency, low-emissions boiler than can burn natural gas and No. 2 heating oil.

The roof, which is covered with a variety of flowering plants, reduces the urban “heat island” effect, extends the life of the roof and absorbs rain water. And as a side benefit, it doesn’t make for a bad view from the upper floors of the nearby Buck Center.

Bowdoin has a mission statement to be mindful of its impact on the environment of coastal Maine.
