1. Project Background 1.1 – Boston, Massachusetts and Tufts University
Tufts University, located in Boston,
Massachusetts, is the site for the
subject of this report, The Jaharis
Family Center for Biomedical and
Nutritional Research. Aside from being
one of the oldest and most historic cities
in the United States, Boston is host for
many notable and renowned Colleges
and Universities. The list of Boston
Colleges and Universities includes The
Berklee College of Music, Boston University, Emerson College, Harvard
University, Dartmouth College, The Massachusetts College of Art, The New
England School of Law, Northeastern University, Suffolk University, MIT, as well
as Tufts University and many others. Boston is truly the American melting pot of
college students.
Being the host to so many institutions of
higher education, Boston is a natural hub of
research activities, many of which are
conducted at Tufts University. Located in
northern Boston and Founded in 1852, Tufts
University is recognized among the premier
universities in the United States. “Tufts enjoys
a global reputation for academic excellence
and for the preparation of students as leaders
in a wide range of professions. Recognized
by the Carnegie Foundation as a

"Doctoral/Research Extensive" institution
based on the breadth of basic and clinical
research conducted, Tufts has extensive
and highly regarded liberal arts, sciences
and engineering programs that draw
outstanding students from around the world
with the highest academic achievement and
standing.” [1]
In the middle of the 1990’s, Tufts University realized its need for a state-of-the-art
research facility. To accommodate the research needs of both its nutrition
program and its school of medicine, Tufts University commissioned the $65
million, 180,000 square foot Jaharis Center. The name of the building was
dedicated to one of the inspirational figures behind the project, Michael Jaharis.
As chairman of the Miami-based KOS Pharmaceuticals and an industry leader in
the creation of new and improved pharmaceuticals, Michael Jaharis issued Tufts
this challenge: Raise $10 million for this new
research facility, and I will match it. [2]
The Jaharis Family Center is the world’s first
collaborative biomedical and nutritional research
center. “The Jaharis Family Center for
Biomedical and Nutrition Sciences will bring
together the expertise of nutrition and basic
sciences to investigate the fundamental
underpinnings of debilitating diseases, including
cancer, heart disease, Alzheimer's and infectious
diseases like cholera.” [3]

1.2 – Project History and Information
The Jaharis Center project was initiated in 1995 by Tufts University.
Architectural Resources Cambridge, the projects architectural firm, was well into
the design process by 1997 when financial difficulties forced the project to be
delayed for several years. When finances for the project were finally secured in
2000, the project was taken back off the shelf, and the design process was
resumed. At this point, additional consulting firms were brought on-board to
finalize the design. BR+A Consulting Engineers was on of these firms. BR+A,
located in Boston, was the primary mechanical consulting firm on the Jaharis
Center project. At this point in the project’s succession, it was already years
behind the original schedule, and time was of great importance. There was
scarce opportunity for design consideration and in depth analysis. Over all other
design influences, project lead-times were the greatest concern.
1.3 – Building Overview
The Jaharis Family Center for Biomedical and Nutritional Research is truly a
multi-use facility. Major space use groups include classrooms, a 202 person
auditorium, offices, conference rooms, a lobby, laboratories, laboratory support
spaces, copy rooms, a receiving/shipping area, kitchens, cafes as well as other
classifications. The total floor area of 180,000 square feet is divided unequally
among the nine occupied levels of the building. The following table illustrates the
square footage for each level.
Floor Area [sqft.] Floor Area [sqft.] Basement 18.000 Fifth 18,750
First 19,600 Sixth 10,750 Second 18,750 Seventh 10,750
Third 18,750 Eigth 10,750 Fourth 18,750 Ninth 10,750

Figure 5 – Basement Plan Use Groups
The first level through level three is 100 percent fit-out as are the sixth through
ninth levels. However, levels four and five are not completely fit-out. The
remaining spaces on these floors are designated for future expansion of Medical
and Nutritional Research and will be fit-out once future research funding
materializes. Until that time, these spaces will remain as shell space separated
from the working spaces by a partition. The mechanical consulting engineers
did, however, take these spaces into account in their load calculations. The shell
space was designed at 2–2.5 cfm/sqft., around 6 air changes per hour.
The following major use group divisions for each level have been generated to
convey the intent of the architect for the use of each level. These diagrams will
be necessary to understanding the goal of the mechanical redesign. Each color
represents a different major space use. There is a color key included on the right
side of each floor plan that indicates the use group associated with each color.
Elevators are highlighted in blue.

The following pictures show different sections, spaces, and views of the Jaharis
Center. In order to fully understand this building, it is essential to understand the
architects’ intention when they designed the Jaharis Center.

1.7 – Building Systems
Building Envelope
The building envelope of the Jaharis Center is comprised of a curtain wall
system. The majority of the envelope is made up of Type 1 Exterior wall (as
designated on the working drawings.) The Type 1 Exterior Wall components,
listed from exterior to interior, are as follows:
• 3 5/8” Brick • 1 1/2” Cavity • 1 1/2” Rigid Insulation • Sheet Rubberized Air Barrier (SRAB) on 1/2” external gypsum sheathing • 6” Light Gauge Metal Framing System
There is no use of BATT insulation in the exterior walls. The resulting R-value for
Exterior Wall Type 1 is 18 [hr-ft2-F/BTU]. All of the exterior glazing is 1” insulated
glass on aluminum frames. The glazing R-value is approximately 1.5 [hr-ft2-
F/BTU].
Electrical System
The electrical system for the Jaharis Center consists of one primary electrical
feed branched off to serve the building’s needs, which include lighting,
mechanical system equipment, and power usage. The primary switchboard with
surge protection receives 480Y/277 V on a 3 phase, 4 wire system.
Transformers step down the voltage supply to 208Y/120 V.
Lighting Systems
The main lighting systems operate on 277 Volts and mostly consist of a variety of
highly efficiency fluorescent fixtures. There is a combination of T8 lamps with
indirect, recessed, and industrial fixtures. Also used are metal halide lamps.
There are also some 120V incandescent fixtures as well as 120V halogen
fixtures which serve the large first floor classroom/auditorium.

Structural Systems
Steel frame construction is used for structural support as well as lateral moment
support for bracing. The composite floor system consists of 3 ¼” light weight
concrete (115pcf, 3000psi) poured on top of 20 gauge corrugated metal decking.
The concrete and corrugated metal roofs are supported by either light weight
long spanning joists or structural steel.
Fire Protection System
A fire department connection on the exterior of the building is available, and a
wet pipe sprinkler system has been designed to serve all of the spaces in the
building. The exterior hookup is in place to allow the fire department to
supplement the water supply and pressure in the event of a fire. A fire alarm
system is also integrated throughout the building with automatic as well as
occupant activated sensors.
Telecommunication Systems
Telephone outlets are located in the majority of spaces in the Jaharis Center,
consistently throughout the offices and classrooms. Television and CAT 5e
cable serve most of the common rooms and offices.
Transportation Systems
Transportation systems consist of 4 cable elevators. The full height of the
structure is also served by two stairwells. The elevators have a capacity of 4000
lbs operating on 480V. Wheel chair lifts are also accessible in the building.
