Energy reduction and renewable generation technologies
"We have designed several cutting-edge energy reduction and renewable generation technologies for the transit center. Our hope is that with features including real-time energy usage monitoring displayed in the building, users will be inspired to look for new opportunities to reduce their own energy consumption.”
- Julian Astbury, Arup Project Manager.
Key design features include:
- 22 geothermal wells buried 405 feet deep.
- 98-kilowatt ground-mounted photovoltaic array, 7,300ft2.
- On-site 750 MBH (750,000 BTU/hour) boiler fuelled by wood pellets from managed sources.
- Air-conditioning provided by an active chilled beam system.
- Solar wall that preheats fresh air by as much as 15° during peak winter sun.
- Second-stage preheating via ground source heat pump.
- Air handling unit incorporating variable speed fans and energy recovery.
- Daylight modelling used to determine optimal placement of windows, clerestory, and skylights.
- All lighting controlled by a system integrating occupancy sensors, photocells, and dimming control.
- LED light fixtures provided in parking lots.
- Low-flow water fixtures yielding 35% water savings.
- Annual energy consumption estimated at less than 35 kBTU/ft2.
At the dedication, Massachusetts Governor Deval Patrick was joined by a number of distinguished speakers including Lt. Governor Timothy Murray and Congressman John Olver. The speakers shared the opinion that this zero net energy facility will be a long lasting contribution to Massachusetts.
“I am pleased to see this innovative investment in the future of transportation and green energy come to fruition and honored by the name designation given to this modern facility.”
- John Olver, Congressman.
