[Greenbuilding] Insulating 140 Year Old Wood Framed Brick Facade Building

I am looking for advice and suggestions on  insulating and air sealing a 3
story 140 yr old (circa 1870) brick facade building. with wood balloon
framing and was hoping list members would be willing to impart some of
their wisdom and expertise.

The current project area is the main floor.

Building frame in order of materials from the exterior:

soft brick

2"x 5" wood studs 1' on center

1" sheathing (widths very from 6" to 30")

vertical lath on top of the studs

horizontal lath (spaced for plaster key ways)

plaster which has been removed.

There is no insulation currently in the building. Brick ties consist of two
cut nails driven into the exterior side of the studs at approximately 2'
intervals and imbedded in the brick mortar joint.

The building is located in USA, Southwest Michigan zone 5, approximately
6,600 hdd, and 34" of precipitation per year.

Walls are 14' tall

As for insulating, the building owners would like to avoid the use of spray
foam as a personal choice.

Some concerns: keeping the brick facade in tack, maintaining the air space
between framing and brick, finding the best solution that keeps the budget
from becoming astronomical (astronomical is subjective I know)


Thanks for your time and any responses
