The Massachusetts Port Authority yesterday unveiled the new $310 million Rental Car Center at Boston Logan International Airport.

The 120,000-square-foot customer service center and four-level garage will have space for all nine rental car companies — Advantage, Alamo, Avis, Budget, Dollar, Enterprise, Hertz, National and Thrifty — that have operating agreements with Logan to work in one common building.

Operated by the Massachusetts Port Authority (Massport), the RCC includes a new shuttle bus. As of today, diesel-powered rental car buses will be eliminated entirely from the airport roadway as bus traffic drops from about 100 buses per hour to 28 fuel-efficient hybrid buses.

As a result, shuttle bus vehicle miles are expected to drop by 70% with an accompanying 35% decline in airport-related emissions, according to Massport.

Another environmental benefit is all rental car companies with operating agreements will now be on airport, reducing traffic and emissions.

"Building a safe, healthy and sustainable transportation system is a priority of Gov. Patrick and critical to everything we do at MassDOT," said Richard A. Davey, transportation secretary and CEO for the Massachusetts Department of Transportation. "This new Rental Car Center and fuel-efficient clean hybrid buses fit perfectly with those broader environmental goals."

To improve customer service and monitor roadway and curb activity, a new operations center in the RCC has the ability to track roadway traffic, passenger demand along the terminal curbs and taxi queues through a series of video displays, according to Massport.

Gaining the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Silver certification, the new rental car facility features 616 solar panels that provide 150 kilo watts of power.

According to Massport, the LEED rating system offers certification levels for new construction that correspond to green design categories: sustainable sites, water efficiency, energy and atmosphere, materials and resources and indoor environmental quality.
