NATURAL SCIENCE CENTER AT HAVERFORD

COLLEGE, HAVERFORD, PENNSYLVANIA

Introduction

The Marian E. Koshland Integrated Natural Science Center (KINSC) reflects the commitment of 

Haverford College’s faculty and administrators to providing a productive, flexible, and motivating 

learning environment. When the evolving space requirements of the institution’s natural sciences 

departments began to exceed those of the existing facilities, the faculty and administrators started 

to investigate the benefits of co-locating all the college’s natural sciences activities. They recognized Haverford College/PIX19379

Project Description 

The KINSC in Haverford is a four-story, 185,423-

gross-ft2 laboratory and classroom building. It houses 

facilities for both undergraduate- and graduate-level 

research activities for seven natural sciences departments 

(biology, chemistry, physics, mathematics, computer science, and psychology). As a fully integrated, cooperative 

educational facility, it also contains faculty offices, 

communal/interactive areas, and a natural sciences 

library. The building construction was completed in two 

phases in 2001 and 2003 at a total project cost of $42.6 million ($230/gross ft2). Ayers/Saint/Gross (ASG) Architects 

and Planners of Baltimore, Maryland, and CUH2A of 

Princeton, New Jersey, provided the architectural and 

engineering design services, respectively. Earl Walls 

Associates of San Diego, California, was the laboratory 

planner, and the general contractor/construction 

manager was Skanska U.S.A. Building, Inc. of Blue Bell, 

Pennsylvania (formerly Barclay White, Inc.).

that most science graduates’ careers will 

require knowledge in disciplines other than 

their degree areas, and that participating in a 

wide range of scientific experiences is in the 

students’ best interests. The planners wished 

to create an environment that provides stateof-the-art research facilities and promotes 

interactions within the laboratory as well as 

among degree disciplines. As a result, the 

185,423-ft2 (gross) KINSC was designed and 

constructed. This distinctive academic center 

includes laboratory, classroom, office, and 

supporting spaces to house all of the Haverford 

College natural science departments. 

The KINSC’s unique mechanical system 

conditions the facility’s makeup air separately 

from the air that maintains thermal comfort. 

Energy wheels precondition the makeup air to 

space-neutral conditions (the temperature and relative 

humidity levels desired for comfort within the building). 

Individual fan-coil units located within each space or 

building zone further condition a portion of this makeup 

air to maintain desired thermal conditions in each space. 

There is no need for reheat because the air entering the 

fan-coil units is at space-neutral conditions. Because the 

conditioned makeup air is distributed through a network 

of plenums, there is very little ductwork in the building. 

Designers estimated that the KINSC system saves 52% in 

cooling and heating energy annually for the entire facility 

as compared to a system using 100% outside air, variable 

air volume (VAV) fume hoods, and no energy recovery. 

When compared to a similar conventional laboratory 

system that incorporates sensible energy recovery, the 

comparable thermal energy savings are still 45%.

This study is one in a series produced by Laboratories 

for the 21st Century (“Labs 21”), a joint program of the 

U.S. Environmental Protection Agency (EPA) and the 

U.S. Department of Energy (DOE). The program is geared 

toward architects and engineers who are familiar with 

laboratory buildings, and encourages the design, construction, and operation of safe, sustainable, high-performance 

laboratories.

Layout and Design 

The KINSC joins the southern ends of the existing 

Sharpless Hall and Hilles Hall. A section of the building, 

known as the “Link,” ties together these existing buildings 

and the newly constructed KINSC. Figure 1 shows the 

KINSC first-floor plan, and Table 1 gives a breakdown of 

space by function. 

Laboratory Design

The laboratory designer worked closely with the 

Steering Committee, which consisted of Haverford 

College faculty and staff, to optimize the laboratory 

configuration and bench design to facilitate teaching. 

Mock-up benches were constructed during the design 

phase so that the Steering Committee members could test 

their bench design recommendations. The “bowtie” bench 

design for the biology laboratories was a result of this process (Figure 2). The open, double hexagonal bench design, 

which encourages interaction between groups ranging 

from 2 to 8 students, also gives a clear line of sight across 

the bench, further promoting conversation between 

groups.

The chemistry laboratory has the more conventional 

straight benches because chemistry students typically work 

on their own, instead of in the groups usually found in 

biology laboratories. Double-sided fume hoods used in the 

larger chemistry laboratories furnish a clear line of sight 

between the professors and the students (Figure 3).

Every teaching laboratory has Americans with 

Disabilities Act (ADA) accessible workstations.

Utility Servicing 

Four vertical interior shafts in each of the building’s 

east and west wings are the conduits through which the 

utilities are run. These shafts also serve as the plenums 

through which space makeup air is delivered. Pipes and 

other utilities run horizontally from these shafts via a unistrut-type rack system mounted to the ceiling. Utilities are 

in a standard stacked configuration with the air distribution 

on top, piping in the center, and data and electrical conduits 

on the bottom to give an organized appearance in the 

spaces without finished ceilings. Makeup air is distributed 

through corridor ceiling plenums as well as the vertical 

interior shafts. Data cable trays and lighting electrical conduits are also routed through the corridor. Exhaust air is 

ducted through separate exterior vertical shafts.

The vertical shafts and plenum distribution design 

strategy maximizes the ceiling height. The floor-to-floor 

height for most parts of this building is 13.5 ft, but ceiling 

heights range from 10.5 ft to 15 ft (these vary according to 

floor and wing). Only the corridors have ceilings installed 

below the maximum floor-to-floor height to accommodate 

the horizontal makeup air plenums. All piping, ductwork, 

and other utilities outside the corridors are exposed to 

maintain the feeling of tall ceilings.

Mechanical rooms are located in the enclosed penthouse on the fifth floor of the east wing and in the basement of the west wing of the newly constructed portions 

of the KINSC. An existing mechanical room in the 

Sharpless Hall basement remains in use. 

The building receives steam service from the campus 

central plant, where most of it is converted to hot water. 

The remainder provides humidification. Two dedicated 

240-ton chillers supply chilled water to the building. 

There are 386 gross square feet of building area per ton of 

chiller capacity in this building, which is very similar to 

common office building capacity requirements. Haverford 

College turns off the chillers and drains and shuts down 

the cooling towers during the winter months to conserve 

energy. 

Communal Spaces

Communal spaces are liberally located throughout the 

building to serve as comfortable and convenient areas 

where students and faculty can congregate. Each communal space contains comfortable seating and a white board 

or chalkboard. These spaces are designed to foster an environment that encourages communication among the students and faculty of the various scientific disciplines 

housed within the building. 

Design Approach

Consensus building was the foundation of the KINSC 

design process. The ASG-led design team and the KINSC 

Steering Committee met regularly throughout the project 

design phase. A variety of tools were employed to help 

meeting participants fully understand the meaning and 

impact of an “interdisciplinary” education. The design 

team tested proposed building design solutions with 

larger campus-wide issues of scale, massing, campus circulation, and building orientation. Three-dimensional 

“blocking and stacking” models, flow diagrams, and 

bubble diagrams allowed design team and committee 

members to visualize space interactions and conceptualize 

building massing. 

The design team and the committee established up 

front that minimizing building operating costs was a primary project goal. Minimizing these costs is directly tied 

to energy efficiency, especially in a laboratory building. 

Because conditioning laboratory ventilation air is a principal source of energy consumption, KINSC designers 

decided to use energy recovery systems, which require colocating the supply and exhaust air streams, early in the 

design process. This necessitated coordination between 

the architectural and engineering designs throughout the 

design phase. 

During the early design phase, the planners also considered the fume hood locations, recognizing how the 

fume hoods interacted with other mechanical system components and adjusting the building design to optimize 

overall mechanical system performance. For example, the 

organic and general chemistry laboratories, the most-used 

laboratory spaces in the building, are located on the top 

floor of the east wing. Locating these laboratories just 

under the KINSC mechanical room shortened the fume 

hood exhaust system, which accommodates the large 

number of fume hoods that these laboratories require as 

efficiently as possible at the lowest cost. 

Technologies Used 

Site Related 

The building project adheres to sustainable design 

practices that minimize disturbances and impacts to the 

site and regional environments. The new facility is constructed on a previously disturbed site and the building 

is physically attached to two existing historic buildings 

(Sharpless Hall and Hilles Hall). To make room for the 

KINSC on the site, two additional buildings were moved 

a short distance instead of being destroyed. 

Heating, Ventilating, and Air-Conditioning 

(HVAC)

The most groundbreaking energy efficiency design 

feature of the KINSC is the strategy used for laboratory 

ventilation and space conditioning. A series of energy 

wheels condition the exhaust and makeup air to create 

space-neutral air. Individual fan-coil units (FCUs) located 

within each space or building zone further condition a 

portion of this makeup air to maintain desired thermal 

conditions in each space. Reheat is not needed because the 

air entering the FCUs is at space-neutral conditions. The 

conditioned makeup air is distributed through a network 

of plenums. Distributing the air through plenums minimizes the need for ductwork and minimizes air pressure 

drops. Designers estimate that the strategy consumes 52% 

less energy than an air-handling unit system that uses 

100% outside air. 

The KINSC system avoids the need to both cool and 

heat all the air delivered to the laboratories. A total energy 
L A B S F O R T H E 2 1 S T C E N T U R Y 5

wheel and a sensible energy wheel work in series with 

heating and cooling coils to condition all incoming 

outside air to space-neutral conditions. Figure 4 illustrates 

how the energy wheels are integrated into the makeup 

air-conditioning system. Designers specified a special 3-Å 

molecular sieve desiccant to ensure minimal cross contamination between the exhausted laboratory air and the 

air delivered to the spaces.

The space-neutral conditioned makeup air is distributed through a building plenum delivery system, which 

consists of vertical shafts that are open to the corridor ceiling plenums on all floors. The fume hoods and general 

building exhaust system passively draw the air from the 

corridor plenums and deliver it into the laboratories. The 

air travels through back-draft dampers that are made of 

fabric and installed in the wall partition between the lab 

and the corridor. These self-adjusting dampers maintain 

a negative pressure of approximately 0.03 in. in the 

laboratory, compared to the corridor. When a laboratory 

door is open, the back-draft damper instantly shuts, 

ensuring inward airflow through the door for improved 

containment.

A simple control scheme combined with the backdraft damper maintains the desired laboratory differential 

pressures. This design avoids the need for a VAV box, 

differential air pressure controls, and a reheat coil on the 

supply air ductwork. The design results in 

a first cost savings and a low supply air 

pressure drop, which saves on fan energy. 

Fan coil units in each laboratory sensibly condition only the quantity of air needed 

to maintain comfortable space conditions. 

Thermostats in each laboratory control the 

FCUs and the FCUs operate only during 

occupied hours. Each FCU serves just one 

laboratory to avoid cross contamination of 

fumes among the laboratories.

The KINSC laboratory HVAC system 

design has many advantages beyond 

heating and cooling energy savings: 

• Ductwork is minimized. Fume hoods and 

general building exhaust system passively draw the makeup air from the plenums 

and into the laboratories. The only supply 

air ductwork that is needed introduces the space-neutral air into the plenums and then delivers the supply 

air from the FCUs in each space. Ductwork is also used 

to direct the fume hoods’ exhaust air into the laboratory 

exhaust air system. 

• No condensation is present in the FCUs. The FCUs 

provide only sensible conditioning because the energy 

wheels previously accomplished all of the required 

dehumidification. Avoiding condensation in the FCUs 

eliminates the need to install a system to remove condensate, along with the possibility of fan coil equipment deterioration problems resulting from moisture 

buildup.

• Control, balancing, and startup are simpler. A standard 

flow tracking control located at one location within the 

makeup air unit synchronizes the makeup supply air 

quantity with the quantity of air exhausted from the 

spaces and maintains constant global building pressure 

conditions. Balancing and startup consists of properly 

setting the makeup airflow tracking controls and calibrating the fume hood exhaust controls.

• Fewer control points and the passive makeup air delivery system combine to simplify the operations and 

maintenance requirements. 

• The system operation is extremely quiet. Because the 

large quantities of makeup air are delivered through 

plenums, the system is virtually silent when operating. The silent operation facilitates instruction in the 

laboratories and classrooms and enhances the learning 

environment.

Figure 4. KINSC laboratory makeup air and comfort conditioning

assumptions: laboratory area of 650 ft2; four VAV fume hoods, each 

operating at an open 900 cfm exhaust; four people working in the 

space, operating internal lighting and equipment load of 5 W/ft2; 

and a summer envelope cooling load of 2400 Btu/h. 
6 L A B S F O R T H E 2 1 S T C E N T U R Y 

One drawback of the KINSC HVAC system has been 

maintenance costs for the high number of FCUs, particularly the costs of filter change outs. This added maintenance cost is acceptable, however, when compared with 

the benefits of lower construction costs, quieter laboratories, and more efficient energy use.

An outside air inlet bypass damper on the suction side 

of the constant volume exhaust air fans maintains constant 

stack velocity. Most of the 110 fume hoods in the building 

are VAV fume hoods (a few constant volume hoods are 

located in the west wing). All the teaching laboratories are 

designed so that one fume hood can remain active when all 

the other fume hoods in the laboratory are shut down. This 

strategy was intended to allow for the continuous operation 

of only one fume hood per laboratory, to meet the minimum ventilation rate for the laboratory, except for the time 

periods when students are occupying the laboratories. 

Of the considered strategies, the mechanical system 

design selected for the KINSC was the strategy that had 

both the lowest first cost and operating costs. The cost of 

the energy recovery devices in the makeup air-conditioning 

system nearly doubled the first cost of this equipment, 

compared to a conventional 100% outside air system. But 

the increased cost for the energy recovery devices was 

more than offset by savings resulting from a reduced 

heating and cooling plant size, the reduced supply-air 

ductwork, and a simpler control system. These savings 

reduced the mechanical system construction cost to 10% 

less than that of comparable facilities built in the region. 

Lighting

Suspended, bidirectional fixtures with T-8 fluorescent 

lamps light the laboratories, classrooms, communal 

spaces, and corridors. In the laboratories and classrooms, 

the fixtures are set to supply 85% of the lighting as down 

lighting and 15% as up lighting, for an 81% fixture efficiency. The fixtures in the communal spaces and corridors 

are adjusted to provide a 50%–50% distribution of up-todown lighting, for a fixture efficiency of 94%. Suspended 

linear fluorescent indirect lighting fixtures with perforated 

bottoms (97% up and 3% down) illuminate the offices. 

Fluorescent task lighting is installed in the offices with 

overhead storage as well as in the library study carrels. 

Compact fluorescent down lights are used in the circulation areas, offices, and library. 

Manual switches control the lighting in the laboratories and classrooms and are wired to permit separate 

switching of rows of lights. A relay-based lighting control 

system is used in the circulation areas. This system 

incorporates time-of-day scheduling, override switches, 

and/or photocells (outdoor and entry lobby lighting). 

Wall-mounted occupancy sensors with switch overrides 

control the office lighting. 

Indoor Environmental Quality (IEQ)

The KINSC design delivers good IEQ through the 

following features:

• The connection with the outdoors is an important 

design feature of the KINSC. Almost all classrooms, 

offices, and communal/interactive areas have operable windows, and all stairwells have operable windows and skylights. Students and faculty report that 

the availability of daylighting and the views to the 

outdoors from virtually all regularly used spaces in 

the building make for more comfortable learning and 

working environments. 

• The mechanical system design results in a relatively 

small amount of air traveling through the FCUs. Less 

air means less noise. 

• No condensation at the FCUs eliminates the possibility 

of indoor air quality problems associated with the 

accumulation of condensate in occupied spaces. 

• Whenever possible, materials and finishes that emit 

low levels of volatile organic compounds (VOCs) were 

used to minimize the introduction of indoor pollutants. 

• The simple control strategy of the mechanical and 

electrical systems in the building ensures that the 

occupants are comfortable in the spaces.

Materials

Locally quarried stone was used as a building façade 

material, and regionally quarried slate is used extensively 

within the building. The precast concrete structural framing was manufactured locally. The concrete masonry units 

(CMU) and most of the ground-faced block was also locally manufactured. Finally, all slate blackboards and some 

of the furniture found in the building were reused from 

other spaces on the Haverford College campus.

Building Metrics

Table 2 summarizes the building’s metrics and provides the estimated energy use calculated using the key 

design parameters. Because the KINSC is not metered separately from other buildings on the Haverford College 

campus, energy use figures, as reported by measured data 

or energy utility bills, are not available. The energy consumption of the ventilation system is low compared to 

other buildings featured in the Labs 21 case study series 

because of the low fan power requirements. Distributing 

the air through a network of plenums minimizes the need 

for ductwork, which significantly reduces system static 
L A B S F O R T H E 2 1 S T C E N T U R Y 7

pressure. Less fan power is then needed to distribute the 

air. The calculated energy use is 22.2 kWh/gross ft2/yr.

Summary

The strong rapport between the design team and 

Steering Committee was a key factor in the success of the 

KINSC project. The building design evolved through an 

iterative process consisting of continuous communication 

between the design team and the Steering Committee. The 

design schedule set at the beginning of the project was not 

adversely affected by the extensively iterative nature of 

the design phase. The final design balanced the program 

interdisciplinary requirements, quality of construction 

and finishes, and budget (final project cost of $230/ft2). 

Finally, the design team and Steering Committee felt that 

they successfully created a building that assimilates well 

into the Haverford campus and constructed a facility that 

can be used and enjoyed by all, not just the scientists it 

houses.

The project construction cost was less than originally 

anticipated, primarily because distributing makeup air 

through plenums minimized the amount of ductwork in 

the building. In addition, the energy recovery system 

reduced the amount of heating and mechanical cooling 

needed to meet building loads, which resulted in 

decreased heating and chiller capacity requirements. 

Designers chose not to install ceiling finishes in most of the 

building as a strategy to give the building a taller, more 

open feeling, and for additional cost savings. 

Other innovative features of the KINSC include locating fume-hood-intensive laboratories on the top floor just 

under the mechanical room (to accommodate the large 

number of fume hoods as efficiently as possible), installing 

FCUs so that each unit serves only one laboratory (to 

avoid cross contamination between laboratories), and the 

practice of turning the chillers off and draining and shutting down the cooling towers during the winter months.
