CaseInPoint Transit station’s retrofit means it’s curtains for infiltrating air Extending the TD Banknorth Garden’s commuter foot trafﬁc area 100 ft into the adjacent train shed relieved congestion. However, it took innovative HVAC engineering and architecture to make the retroﬁt an energy-saving and aesthetic solution. Previously, thousands of mass transit commuters were funneled into the cramped congested lobby/walkway area of the Massachusetts Bay Transit Authority’s (MBTA) renowned North Station terminal inside the TD Banknorth Garden, the home of the Boston Celtics and Boston Bruins. The successful multi-million dollar expansion, developed and funded by Delaware North Companies, Inc. (the owner the TD Banknorth Garden), now greets commuters with a very energy-efﬁcient indoor environment thanks to air curtains, proper building pressurization, and an innovative and aesthetic HVAC, supply sofﬁt system. MEETING RUSH HOUR DEMAND Previously, the MBTA’s narrow 30-ft-wide lobby/walkway area’s trafﬁc spilled over into the automatic entry door sensor zones, thus exterior sliding double doors remained open continuously during rush hours, resulting in signiﬁcant energy losses into the open-ended train shed. While the renovation’s main objective was better trafﬁc ﬂow and a roomier waiting area, controlling energy losses through more efﬁcient doorways was also a major concern. Air curtains were chosen for the TD Banknorth Garden as much as for aesthetics as for performance. Each recessed 3,624-cfm air door distributes a maximum 3,500 fpm stream of air angled directly down toward the floor, thus cold (or hot in the summer) train shed air and fumes are kept outside of the receiving area. “We knew going into this project that one of the greatest challenges was saving energy for the client, because many doors would be constantly open from continuous foot trafﬁc,” said Jeffrey Fleish- UNIQUE SENSING INTELLIGENCE. HygroClip2 – Innovation in Humidity and Temperature Measurement Innovation is the key for the All-New HygroClip2 and AirChip3000 from Rotronic. The latest development from ROTRONIC raises humidity and temperature measurement to new heights of performance.
