Executive Summary
Designed for Project Managers (PMs), Architects and Engineers (A/Es) and Laboratory
Design Consultants.
Good laboratory planning and design will provide a safe, efficient and collaborative
environment for scientific research and teaching. This pursuit must, at all times,
recognize the University‟s commitment to lessening its environmental footprint,
including minimizing the release of airborne particulates and reducing greenhouse gas
emissions, which stem in large part from the combustion of fossil fuels used in the
process of providing illumination, ventilation, and air-conditioning, etc to support the
laboratory work environment. It is at this intersection where some of the most difficult
design and future operation decisions are considered. In achieving these goals, it is
essential for all stakeholders to openly engage in these discussions. Outlined below are
Columbia University Guidelines for Laboratory Design (“Guidelines”) by which a design
team, and other stakeholder, including client representatives and/or Principal
Investigators, using a combination of general laboratory programming, planning, design,
documentation and project delivery processes, will develop a safe and efficient lab
environment based on the specific needs of the laboratory in an energy-efficient and
environmentally sustainable manner. This document provides minimum requirements;
more stringent requirements may be necessary depending on the specific laboratory
function or contaminants generated.
The University is one of the founding members of the PlaNYC University Mayoral
Challenge and is committed to reduce greenhouse gas emissions 30% by the year
2017. All laboratory designs shall implement energy efficient measures to achieve this
goal.
These Guidelines were formulated as a consensus document among all members of the
Laboratory Design Working Group (Appendix I). All laboratory design teams shall
consult with Columbia University‟s: Environmental Health & Safety (EH&S), Facilities
and the Office of Environmental Stewardship (OES) during the schematic design phase.
These offices shall be involved throughout the design process. The Guidelines shall be
reviewed to incorporate regulatory changes, industry developments and best practices
on an annual basis.

Layout Requirements
To the extent possible, laboratories should be oriented to take advantage of natural
lighting (with consideration for controlling sunlight and glare). This desire must be
balanced against the energy modeling goals established for sustainability,
therefore operable windows must be in conformance with the intent of the project
and space, and must be accounted for in the HVAC design. Operable windows are
acceptable in office areas, but not laboratory space. Operable windows in
laboratory space shall only be permitted based on a demonstrated research need
or Facilities requirement, and following consultation between the end-user, CUF
and/or CUMC CPM, and EH&S.

12
COLUMBIA UNIVERSITY
GUIDELINES for LABORATORY DESIGN
5.4
Furniture
Furniture shall be scheduled to the extent possible with standardized dimensions and
parts and in compliance with university-wide campus standards.
5.5
Lighting
5.5.1 General

Day lighting shall be maximized where possible for user comfort. Lighting
should be even across the room, with a maintained light level capable of 75
foot-candles on the work surface. Non-laboratory space shall follow Illuminating
Engineering Society (IES) standards. A combination of lighting zones,
dimmable fixtures, and controlled daylight and occupancy sensors with
adjustable sensitivity in the room is ideal. Fixtures should control glare and
should not produce veiled reflection in the room or on equipment and render
colors accurately and uniformly with minimum eye strain. If a room is multifunctional, the A/E is responsible to account for the lighting design
considerations for the various tasks that are to occur in the different sectors of
the room.

If a space has a ceiling above 12‟ in height, the project team shall review all
access requirements for light fixture maintenance and incorporate any fixed
requirements such as access panels, into the documents.

Much of the public space lighting on the University campus is controlled by
occupancy sensors. Typically, at least one light in a space will be on an
emergency circuit or per building code which ever one governs. The occupancy
sensor is to be wired upstream of a conventional light switch so it operates as a
vacancy sensor. The operation of occupancy sensors should be carefully
coordinated with the room use. All designs must comply with applicable codes

Ceiling mounted ultrasonic sensors (or better) shall be used in corridors to turn
off lights. Select fixtures shall remain “on” at all times in sufficient quantity to
maintain a minimum of 2 foot candles for security and safety. (It is the intent
that these select fixtures be part of the back-up generator powered emergency
egress lights, rather than a set of additional fixtures.)

Lab area lighting is to have automatic controls (day-lighting, sensors, etc.) as
previously described unless lab functions require special consideration. Task
lighting at lab benches need not be automatically controlled.

Lighting fixtures should not be placed where they will obstruct or interfere with
the spray pattern of sprinkler heads. (Refer to NFPA 13).
5.5.2 Lighting types

T-5 fluorescent lighting or Light-Emitting Diodes (LED) are standard for the
University. Indirect/direct lighting is preferred for its even quality, however
should only be considered when ceiling height is adequate (9‟-6” minimum). For
any needed down lighting or highlighting, a compact fluorescent lamp, T-5
fluorescent or LED may be used as appropriate. Incandescent fixtures are not
to be used; an LED fixture may be used to mitigate RFI concerns.
13
COLUMBIA UNIVERSITY
GUIDELINES for LABORATORY DESIGN

5.6
In public spaces or where special lighting is required, the A/E may submit
alternate lighting systems to the CUF or CUMC CPM for review and approval.
Storage (Chemical)

NYC campuses must adhere to 2008 NYC Building, 2008 Fire Code, Title 3
Section 4827-01(G) (1), and NFPA 45, 2004 edition. The A/E is responsible to
confirm all hazard, code and regulatory issues that apply to the design of the
project and be coordinated and approved by EH&S, and CUF or CUMC CPM.

Minimum code required clearances for sprinklers shall be maintained including
considerations for JCAHO spaces, where applicable. (See „Casework‟, above).
Explosion-proof or flammable-proof refrigerator shall be used if flammable
materials must be stored.

Explosion-proof hoods, equipment, finishes, systems, etc. shall be designed and
specified where required by applicable codes.

Chemical storage is not permitted underneath sinks; prohibition label will be
affixed to the cabinets.

Cabinets for chemical storage should be of solid, sturdy construction, with built-in
partition for separation of incompatible chemicals for secondary containment, and
vented as required by applicable code.

Flammable gases or liquid storage, use or dispensing is not permitted below
grade or near a means of egress.

Storage of corrosive chemicals (acids and bases) shall be so arranged that there
will be no contact with bare unprotected metals or casework. Storage cabinets for
corrosive materials must be poly-lined and protected. Additionally, oxidizing acids
cannot be stored on cellulosic material.

Laboratories which operate High Performance Liquid Chromatography (HPLC) or
related equipment must have a workstation which is designed so that waste
bottles are not stored on the floor.

Laboratories using compressed gases should have areas designated for cylinder
storage and be equipped with devices to secure cylinders in place. Cylinders
must not be secured to plumbing or electrical conduits. Cylinder Manifold
systems shall be designed to be readily accessible for FDNY inspection and
have required permit information readily available.

Flammable Storage Cabinets whether stand alone or incorporated under
chemical fume hoods are suggested as flammable limits are allowed to be
increased (or doubled) with the presence of a Flammable Storage Cabinet in a
laboratory
5.7
Storage (Regulated Medical Waste)

Adequate storage/staging shall be provided for containers awaiting removal
and for an adequate reserve.


latch side of the door leading to the laboratory located in the area of the midpoint of the height of the door. (RCNY Title 3, Chapter 2706-01).
MEP Guidelines for Laboratory Design
6.1 MEP General Design Considerations

Overall, MEP distribution shall be based on a modular layout. Systems
shall be designed to ensure reliability, maximize operational flexibility and
capacity for renovation, allow service to occur without interfering with
research, and to minimize potential for disruption due to single point
failures and routine maintenance. At the same time, systems will be
“right-sized” so as to maximize energy efficiency and take account of
fewer air changes as appropriate (Appendix III).

A primary goal for distribution systems is to minimize floor penetrations in
laboratory areas.

A/E shall utilize efficient capacity methods for sizing primary equipment to
provide required redundancy and overage while maintaining energy
efficient operation for the normal operating load profile.


standards of code as a result of the new work. This may require the A/E
to study existing infrastructure and systems capacity far beyond the actual
planned point of connection to ensure adequacy.

The design shall carefully consider cost effective approaches that shall
result in economical arrangements of MEP services including risers,
mains, branches, run outs for both valving and circuiting arrangements
that allow for shutdown of individual laboratories, as well as independent
isolation of each floor, building wing, and zone without affecting other
areas.


Executive Summary
The purpose of laboratory ventilation is to help provide a safe environment for
scientific research and teaching. Outlined below are Guidelines by which a design
team, using a combination of general laboratory ventilation, fume hood exhaust
systems and other local exhaust ventilation, will design a safe and energy efficient
system to contain emissions within the laboratory, depending on the specific needs
of the laboratory. This document provides minimum requirements; more stringent
requirements may be necessary depending on the specific laboratory function or
contaminants generated.
The University is one of the founding members of the PlaNYC Mayoral challenge
committing to reduce greenhouse gas emissions 30% by the year 2017. All
laboratory designs shall consider energy efficient measures to achieve this goal.
These Guidelines were formulated as a consensus document among all members of
the Laboratory Design Working Group (listed in Appendix I). All laboratory design
teams shall consult with Environmental Health &Safety (EH&S), Facilities Operations
(Facilities) and Office of Environmental Stewardship (OES) during the schematic
design phase. These offices shall be involved throughout the design process so as
to ensure that University safety and energy efficiency goals and commitments are
met in a timely and cost-effective manner. The Guidelines shall be reviewed to
incorporate regulatory changes, industry developments and best practices on a
regular basis.

2.1
Laboratory
Laboratory means a facility where the "laboratory use of hazardous
chemicals” occurs. It is a workplace where relatively small quantities of
hazardous chemicals are used on a non-production basis [OSHA
1910.1450(B)].
2.2
Chemical Fume Hoods
Chemical Fume Hoods - means a device located in a laboratory, enclosed
on five sides with a movable sash or fixed partially enclosed on the
remaining side; constructed and maintained to draw air form the laboratory
and to prevent or minimize the escape of air contaminants into the
laboratory; and allows chemical manipulations to be conducted in the
enclosure without insertion of any portion of the worker‟s body other than
hands and arms.
The purpose of a chemical fume hood is to contain airborne substances, to
prevent them from entering the breathing zone of laboratory workers and
occupants and to trap or exhaust the airborne substances without
increasing the risk to the user, occupants of the area, or the environment.
The hood should be designed to incorporate user needs, room configuration
and general ventilation and must have adequate space for hood service and
utility connections.
Fume hoods must be selected from among the following manufacturers:
 Bedcolab Limited
 Lab-Crafters Inc.
 Labconco Corporation
 Thermo Fisher Scientific
The selection of any other fume hood model must be justified on the basis
of program requirements and be approved by CUF, CUMC CPM and EHS.

7.2
Hood Designation
Perchloric Acid (HClO4) may only be used in fume hoods designated and
designed for its use. The hood must be clearly labeled as a “PERCHLORIC
ACID FUME HOOD.” Where confusion is possible, other hoods shall be
labeled “NO PERCHLORIC ACID” in 2” tall black letters on a yellow
background.
7.3
Exhaust Requirements
7.3.1
Each hood installation must have a dedicated exhaust stack and
fan equipped with its own wash down system and fan on/off control.
7.3.2
Perchloric Acid Fume Hood (PAFH) exhaust may not be connected
to a non-PAFH exhaust system for energy recovery or other
convenience.
7.3.3 To mitigate risk and cost associated with the PAFH exhaust
system, it is recommended that PAFH be installed on the top floor
of laboratory buildings.
7.3.4 Bends in ductwork should be avoided, but where necessary pairs of
45 degree bends will be used in lieu of 90 degree bends. Round
ductwork is recommended.
7.3.5 Since the user will have on/off control of the PAFH exhaust fan, air
flow exhausted through the PAFH must not be used by designers to
satisfy the required laboratory ventilation rate (air changes per
hour.) It is recommended that a separate general lab exhaust be
provided with a motorized VAV damper interlocked to the PAFH
exhaust fan control to reduce the general exhaust while the fume
hood is in operation.
7.3.6 The user should turn off the PAFH exhaust fan when the fume hood
is not in use to conserve energy.
7.4
Exhaust Scrubbers
Exhaust scrubbers are difficult to monitor and maintain, and are not
recommended for new installations. A thorough evaluation of more reliable
alternatives must be presented before a retrofit to an existing laboratory of a
PAFH equipped with a scrubber will be approved.
42
COLUMBIA UNIVERSITY
GUIDELINES for LABORATORY DESIGN
7.5
Wash Down Facilities
7.5.1
Each PAFH must be provided with a laboratory waste (acid) drain
and a cold water supply.
7.5.2
The PAFH exhaust stack, fan, and internal hood baffles must be
provided with cold water spray nozzles activated by a series of
electric solenoids controlled by a wash down timer control system.
7.5.3 When wash down is initiated, the fan will shut down, and the water
spray solenoids will activate sequentially starting at the very top of
the exhaust stack and completing below the stack washing down
the internal baffles of the fume hood. All wash down water will be
collected by the laboratory waste drain provided.
7.5.4 The PAFH user who initiated the wash down and is familiar with the
normal operation of the control system will remain present in the lab
during wash down to report a malfunction or leak to Facilities.
7.5.5 The PAFH user must wash all surfaces of the interior work space of
the hood to complete the wash down. It is recommended that a
hand held spray nozzle capable of flowing 1 to 2 gpm and drain be
provided within the workspace to facilitate this operation.
7.6
User Controls
7.6.1
Complete automation (remote or BMS control) of the wash down
facilities must not be provided.
7.6.2
The PAFH user must clear all apparatus and chemicals from the
hood prior to initiating a wash down to avoid damaging equipment
or causing spills and/or injury.
7.6.3 The PAFH user must be trained in the safe operation and
maintenance of the fume hood and the handling of Perchloric Acid.
The user‟s safety is best assured by his or her knowledge and
control of the work space.
43
COLUMBIA UNIVERSITY
GUIDELINES for LABORATORY DESIGN
7.7
Wash Down Frequency
7.7.1
Occasional or Intermittent Use: The user shall perform a wash
down at the conclusion of the experiment prior to turning the fume
hood over to another user or leaving the hood unused.
7.7.2
Continuous Use: Once per month continuous use operations shall
be interrupted and a responsible user shall perform a wash down.
7.7.3 Maintenance Activity: Facilities personnel shall perform a wash
down prior to commencing any maintenance activity on the fume
hood, fan, drain, or exhaust stack. When maintenance personnel
are unfamiliar with the wash down procedure, they will enlist the aid
of experienced laboratory personnel prior to lock out/tag out of the
fan.
7.8
Non-Corrosive Materials
The use of non-corrosive, smooth and water tight materials is required for all
components involved in the construction of the hood, exhaust stack, drain,
water supply and fan. Compatible plastic materials are ideally suited, but
likely to require a variance in NYC for ductwork. Welded stainless steel is an
alternative where plastic may not be used.
7.9
Commissioning
Application of a water soluble dye and camera inspection are recommended
for commissioning the PAFH wash down facilities. Wash down timers should
be field adjusted to achieve satisfactory cleaning with minimal wasted water.
Additional spray nozzles are likely to be required where bends are made in
ductwork.
8.
Criteria for Radioactive Fume Hoods
Radioactive Materials, as far as fume hoods are concerned can be divided
into three categories: High, Medium, and Low Volatility.
8.1
High Volatility
For example: radioactive iodine (I-125; I-131)
The use of fume hoods in these cases is mandatory. The exhaust
of fume hoods, used for iodination, must be vented directly to the
44
COLUMBIA UNIVERSITY
GUIDELINES for LABORATORY DESIGN
roof of the building.
Activated Charcoal filters are optional
depending on the amount and frequency of the iodine used.
8.2
Medium Volatility
For example: 5 millicuries or more of Sulfer-35 in the form of
Methionine or Cystien 100 millicuries or more of Hydrogen-3 in the
form of Tritiated Water.
The use of fume hoods in these cases is recommended and is
decided by the Radiation Safety Committee and the Radiation
Safety Officer (RSO).
8.3
Low Volatility
For example: Phosphorus-32 compounds
No fume hood is required unless the amount of activity is 1
millicuries or more.
Note: When working with an unsealed alpha emitter radioactive
material such as Polonium-210, a glove box with HEPA filtered
exhaust must be used. The RSO must be consulted before the use
of such an apparatus.
8.4
General Requirements
8.4.1 Laboratory hoods in which radioactive materials are handled must
be labeled with the radiation hazard symbol.
8.4.2 Fume hoods intended for use with radioactive materials must be
constructed of stainless steel or other materials that will not be
corroded by chemicals used in the hood.
8.4.3 The cabinet on which the hood is installed must be adequate to
support shielding of the radioactive material being used.
8.4.4 The air velocity at the hood opening follows the ANSI standards.
8.4.5 Laboratory hoods must be provided with means of containing minor
spills.
8.4.6 Liquid radioactive waste with high activity must be stored inside a
fume hood with adequate shielding
