Before
All interior spaces
were worn, tired, and
in need of repair
Historic features were
damaged or covered
over
Before
Antiquated, inefficient
heating system ran open
all winter longtemperature in rooms was
controlled by opening
and closing windows
Inefficient electrical &
plumbing fixtures
Asbestos Abatement
Vinyl asbestos
tile was
removed at
the beginning
of the project

C&D Recycling
All construction debris was either separated and
recycled on site, or was sent to E. L. Harvey’s
construction & demolition debris recycling facility in
Westborough, MA for sorting - an average of 85% of
C&D debris is recycled at the facility

Boilers & Hot Water
New technology:
Lochinvar Knight gas fired boilers- 151,000 BTU’s each,
96% efficient operation, modulate from 20% capacity
to 100% capacity to maintain temperature to keep fuel
costs low and efficiency high
Indirect hot water provided by the boilers- 67 gallon
storage tank
Grundfos Magna 40 pumps- modulate water flow
throughout the building depending on heating load to
reduce the electrical load during the heating
operation & help maintain a comfortable building with
minimal temperature swings
Boilers & Hot Water
New technology (continued):
Johnson Facility Explorer controls system- monitors 20
heating zones & is capable of remote access
monitoring, scheduling, trend data, & alarm outputs
The supervisory controller (FX60) speaks to all building
automation languages & enables Lasell College's
facility staff to monitor & access other building
automation systems on the HVAC network
Control valves modulate to maintain water flow to
each individual zone and maintain precise
temperature control to prevent drastic temperature
swings.
Boilers & Hot Water
Old technology:
2 Hydrotherm hot water boilers- 300,000 BTU’s
each
Zone valves left open during the whole
heating season
Manual controls- opening & closing window
