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 long- temperature in rooms was controlled by opening and closing windows

Inefficient electrical & plumbing fixtures

Before

Asbestos Abatement

Vinyl asbestos tile was removed at the beginning of the project

Water Service

Old- the old, undersized water service was replaced

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

HVAC Controls

Old(None)

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.
