Architecture
The Marcella L. Duffy school was first opened in the 1870’s and served as the first public school in the community. The school was closed in 2008 due to the expensive costs of the heating, ventilation and air-condition systems. The Duffy School addition and renovation with turn the original school into an affordable senior citizen apartment complex. The original school building will be turned into 35 apartment units. The addition, which will be on the east side of the school, will add another 18 units. In addition to the 53 apartment units there will also be a community room, fitness center, craft room, library, and an entertainment facility.

Historical Requirements
The Duffy School is over 140 years old and has many features that need to be saved/preserved while the building is being renovated according to The Duffy Urban Renewal Program and by Florence Township. No historic features exist on the ground floor. In the existing gym and auditorium on the first floor, all existing trim, details, windows, flooring, and ceilings must be saved or preserved. Also on the first floor in the lobby the columns and pediment vestibule must be saved. In the auditorium on the second floor all existing trim, details, windows, flooring, and ceilings must be saved or preserved.
Building Enclosure
The facade for the existing building will be the repaired/restored historical brick facade that previously existed on the Duffy School. The new addition enclosure will match the renovated building with historical brick facade. The connector area between the existing building and the new addition will have a curtain wall on the south side of the building facing Second Street.

Building Roof
The roof is a fully adhered ethylene-propylene-diene-monomer (EPDM) roofing system. The EPDM roof has a thickness of 60 mils and the exposed face color is white.. The EPDM roof sits ontop of R-25 resnet grade 1 insulation. Under the R-25 insulation is a 2.5” layer of spray foam insulation and R-38 total roof insulation. The insulation will sit ontop of 5/8" exterior grade plywood sheathing.

The Green Future program checklist contains a list of green building items that go over siting, land use, energy efficiency, water conservation, indoor air quality, building durability, etc. The program allows for healthy and enjoyable interiors for residents.
