Plymouth Community Intermediate School

The Plymouth Community Intermediate School is a one-story structure that was built in the 1970s, and originally designed for open-concept learning.  This approach provided for open areas of space, but afforded little acoustical and temperature control.  Building systems were powered by electricity and were designed to accommodate these larger open areas.  Moving away from this model, the school moved to a more traditional approach and has implemented individual classrooms.  However, the use of walls and interior barriers had led to inconsistent temperature and deficient ventilation.  The mechanical systems were in need of replacement because of this limited capacity, and also due to age.  In addition, the school was facing fiscal crises stemming from the 150% electricity rate increase.   

RDK designed a new HVAC system that included energy-recovery and ceiling-induction units, are the first of their kind to be installed for schools in Massachusetts. They are saving the Town between $300,000 and $500,000 annually while providing an exceptional level of indoor air quality. Project challenges included working within a tight budget and schedule while the school was still operational, requiring creative phasing in a manner that did not affect the school’s schedule.

This highly successful project was completed on time, on budget, and received $323,789 in total rebates from NStar as a result of the substantial energy improvements made.
