SUSTAINABLE DESIGN

Each year, the MBTA makes major capital improvements to its stations, facilities, bridges and rights of way to try to  keep these assets in a state of good repair.
 
As part of the planning and design of those projects, the MBTA has incorporated sustainable design principles into these projects. Using the leadership for environmental and energy design (LEED) as guidance, these design standards & principles focus on energy and water conservation, use of recycled and sustainable materials and other elements result in new facilities that not only have a smaller environmental footprint, but also often cost less to operate because they consume less water & energy.

 

Assembly Station

Assembly Station is the newest addition to the Orange line, opening on September 2, 2014, creating a stop between Sullivan Square and Wellington station. The station has been designed with many sustainable elements. This new location was specifically chosen to promote transit oriented development, car free living areas, multi-modal transit, and smart growth objectives.

Assembly StationTransit oriented development is a critical part of the sustainability program at the MBTA. Assembly square was designed from the ground up as a mixed use car free living area combing apartments, grocery stores, transit, and jobs all in one location. Assembly square is a great example of the value of transit oriented development that enables dense, sustainable, and convenient living.

The station has many sustainable design elements. The layout and orientation takes advantage of day lighting, and the large roof overhangs block summer sun to reduce heat gain during the summer and allowing more sun during the winter. There is natural ventilation throughout the station and sun shades on the curtain wall which reduces heat gain during the summer.The green roof over the canopy serves several important purposes. The first is water absorption, filtration, and storage that reduces the strain on the drainage system and insures runoff is cleaner. The second is reductions in the energy required to heat and cool the station. The green roof acts as a natural insulator in the winter and a natural coolant in the summer reducing both the energy used by the station’s HVAC system. Also the non-canopy roof is light colored and reduces the heat island affect.

Additional sustainable design elements in the station include electric traction elevators, high-efficiency lighting, low-flow toilets and faucets, no-VOC paint, and locally soured materials such as granite and concrete.

Sustainable Design 1Orient Heights Station 

Recently the renovation of the Orient Heights Station was completed to make the station more accessible for persons with disabilities. The renovation also included numerous environmental and sustainable features. This station now has energy efficient heating equipment, high efficiency windows, machine-room less elevators, lighting control systems, low-flow water fixtures, LEED-certified benches and finishes, solid surface countertops and tile in the Train Operations Building, sustainable harvested hardwoods, and paints that do not include volatile organic compounds. There will be solar panels on the roof that will provide 20% of the station’s needs. In addition there will be a green roof on the train operations side of the station that will help cool the building and utilize rainwater discharge.Sustainable Design 2

 MBTA Police Headquarters' Roof Police roof

General maintenance of buildings at the MBTA is an on-going process. For example, the Transit Police headquarters' roof was failing and needed to be replaced because it was beginning to leak.

The MBTA chose a roof system that combined a proven track record of success at industrial facilities along with sustainable design and construction characteristics that made economic sense.

The roof membranes contain over 20% recycled content and the adhesive used contains no VOC’s. Volatile Organic Compounds could have short- and long-term adverse health effects and the MBTA discourages the use of products that contain VOC’s. The color and reflective finish minimizes roof top temperatures and reduces electricity used for cooling the building. The consistency of the reflective cover also helps assist with storm water run off and to get water/snow off the building. In addition a percentage of the old insulation was recycled through a vendor in Worcester.

  Hingham Intermodal Center Hingham rendering

The new Hingham Intermodal Center will be located in the historic Hingham Shipyard.  The project has been many years in the making because of land issues and requirements associated with the demolition of the building on the proposed site.

The MBTA committed to building an efficient, modern structure with a number of sustainable features included in the design.  The initial goal was to achieve LEED silver level qualifications.  That goal was not only met, but the eventual design and construction meet LEED gold standards.

The center was designed to include large open spaces with plenty of natural light.  The building includes a number of environmental elements addressing valuable resources such as water and energy, and a green roof that helps control storm water discharge and keeps the facility cooler in the summer.  All rest rooms have low flow plumbing and the landscaping selected requires no outdoor irrigation.  As with all new MBTA construction work, the paints, adhesives, and sealants do not contain any volatile organic compounds (VOCs).

One of the more environmentally friendly aspects of the project is the efficient design of a multi-zone HVAC system.  The demand controlled ventilation system will include a geothermal heat exchange that will help offset some of the energy required for heating and cooling.  Geothermal heat exchange takes advantage of the natural subterranean temperatures that exist beneath a structure, and therefore, saves energy costs associated with heating and cooling the building.

This 8,400 square foot Intermodal Center will include major open spaces, modern efficiencies, and environmentally friendly features that will allow the public to enjoying the historic shipyard and travel to Boston from a beautiful destination.

The facility will be the terminal for MBTA ferries that run from Hingham to Downtown Boston.  The ferry terminal is being developed in cooperation with the Massachusetts Department of Conservation & Recreation (DCR), which will use the ferry terminal to provide its service to the Boston Harbor Islands.
