HVAC Replacement Project

In February of 2019, the Engineering Firm SMRT was hired to
perform a complete assessment of the Nashua Police
Department’s HVAC System. Some of the highlights of their
assessment follow

The HVAC systems for the Police Station were designed in two
stages with the original part of the building designed in 1977
and a subsequent Addition Project in 1999

The 1977 design is based on water source heat pumps and
the 1999 design is based on Variable Air Volume System

Detective Bureau

Several windows no longer have a rubber gasket surrounding
the window allowing cold air, bugs, and moisture to enter the
building. This is also a large source of heat/energy loss
throughout the building

sheetrock wall

Several windows leak water and snow causing damage to
sheetrock walls

Window Replacement Project

Original portion of building built in 1979
There are 47 original windows in building

Many are failing causing ingress of weather
and energy losses

A bid (IFB1075-010319)was obtained from D.L.
King in the amount of $134,500 to replace the
47 failing windows

These windows will be the same as the
windows installed in 1999
