PROVIDENCE — Mayor David N. Cicilline has signed an executive order requiring that all new municipal buildings be certified as high-performing, “green” facilities.

The mayor’s order mandates that buildings meet one of two nationally recognized standards in energy-efficient construction: the Leadership in Energy and Environmental Design (LEED) or the Collaborative for High Performance Schools (CHPS).

“This is about ensuring that we make smart decisions about school construction and municipal office space while creating green-sector jobs for our residents,” Cicilline said at a news conference on the rooftop of the Providence Career and Technical Academy on Broad Street, the first city building that will be green certified.

The executive order is the first task that Cicilline has completed of his 30-point plan, called Operation Opportunity, to create a better job climate in the city. He said in his State of the City address in February that he intends to complete all the tasks within 18 months.

Cicilline said that while the executive order on green building will result in an estimated 3-percent to 5-percent increase in overall construction costs, those expenses will be offset by the savings that will be incurred over time as a result of the energy efficiencies.

When the Career and Technical Academy is opened in the fall, it will meet CHPS standards. It will feature an array of panels that power a solar-thermal hot-water system, high-efficiency boilers and chillers, and high-efficiency lighting fixtures.

Nathan Bishop Middle School, when its renovation is completed in August, will also meet the standards.
