A science building may contain offices, classrooms and meeting rooms, but its laboratories are designed around the research taking place inside them. That means planning for equipment, utilities, ventilation, hazard control, safe movement and future changes—not simply fitting benches into an office floor plan. The precise requirements depend on the research, its risks, applicable rules and the building’s location; there is no single design template for every science facility.
The central difference is what the building must support
A standard office is primarily arranged to support people working at desks, meeting and collaborating. General building systems provide a comfortable environment and services for typical office equipment. A science building may include these same functions, but its laboratory areas must also support research procedures and the equipment used to carry them out.

That distinction affects the building as a whole. Laboratory work can call for specific ventilation, specialized utilities, containment equipment, controlled circulation and room for instruments to be installed or moved. A decision about one element—such as where to place a hood—can affect airflow, aisles and egress. Planning therefore has to account for interactions between research activities, safety measures, building services and the people who operate the facility.

A teaching lab, a wet research lab, a dry computational lab and a facility handling biological hazards can involve very different equipment and risks. The applicable design should follow the work and relevant institutional and jurisdictional requirements, rather than an assumed universal definition of a “laboratory.”

How the main building systems differ
| Design issue | Typical office purpose | Research or laboratory consideration |
|---|---|---|
| Air handling | Support occupant comfort and general indoor conditions. | May require local exhaust, contaminant control, pressure relationships or dedicated ventilation arrangements suited to the work. |
| Safety equipment | Ordinarily does not include laboratory containment equipment. | May include chemical fume hoods or biological safety cabinets selected for particular hazards and procedures. |
| Utilities | Serve typical office equipment and general building needs. | May need additional or specialized services for research equipment, with spare capacity to accommodate changes. |
| Layout and circulation | Organized around desks, collaboration and meeting rooms. | Must account for benches, equipment access, containment devices, safe egress and movement of large equipment. |
| Adaptability | Many changes can be handled through office reconfiguration or tenant improvements. | Research changes can affect equipment, utilities and safety systems, so flexibility and capacity for future needs matter. |
Ventilation is linked to hazards and procedures
Laboratory ventilation is not simply an office comfort system with more air. Some laboratory operations may need local exhaust to capture contaminants near where they are generated. A chemical laboratory may also use pressure relationships as part of its approach to controlling movement of contaminants. The appropriate arrangement depends on the work, the hazards and the facility’s design.
OSHA’s Appendix A to the laboratory standard presents National Research Council recommendations on chemical hygiene. It discusses local exhaust, continuous air replacement, pressure relationships in chemical laboratories and avoiding recirculation of laboratory air. The appendix is explicitly nonmandatory guidance; it should not be presented as a binding, universal specification for every laboratory or jurisdiction. It also does not establish one air-change rate that applies to all labs.
In practice, ventilation is one part of a broader control strategy, not a substitute for matching the room to its specific work. A pressure relationship, exhaust arrangement or other ventilation feature should not be assumed to apply identically to every lab. A teaching room, a chemical operation and a space handling biological materials can have different needs. Decisions should be based on the hazards and procedures being addressed, and on the applicable standards for the project.

Ventilation decisions have operational consequences as well as safety implications. The CDC and NIH’s Biosafety in Microbiological and Biomedical Laboratories (BMBL), sixth edition, recognizes the substantial energy implications of ventilation. That is one reason design decisions need to be considered in context: the system must suit the risk and work, while also being understood and operated as part of the facility. Laboratory staff need to know how relevant ventilation and exhaust equipment works.
Fume hoods and biological safety cabinets do different jobs
Containment equipment is chosen for the hazard and procedure; the devices are not interchangeable. NIH facility guidance distinguishes chemical fume hoods from biological safety cabinets (BSCs): fume hoods provide personnel protection from chemical hazards, while BSCs, used with appropriate practices, procedures and administrative controls, provide primary containment for potentially infectious microorganisms.
This difference influences the floor plan. Equipment placement must account for circulation aisles and egress paths, as well as airflow disturbances that could interfere with performance. A device cannot be treated as a piece of furniture that can be placed wherever a bench happens to fit. Its location is part of the room’s safety and operating arrangement.

- Power drill cordless with 1/2" single sleeve ratcheting chuck provides tight bit gripping strength, making bit changes faster and more secure
Nor does the presence of a science building automatically mean every room needs a hood or BSC. Equipment selection follows the activities and risks in that space. Biosafety, in particular, is integrated: facility design, safety equipment and work practices work together, and the appropriate measures depend on biological-agent and procedure risks.
That integration matters because a piece of equipment alone does not define the level of protection a space provides. The BSC’s role depends on appropriate practices, procedures and administrative controls, alongside the facility design. The room layout must allow the selected equipment to function as intended and allow people to circulate and exit safely.
Utilities and equipment need room to evolve
Research instruments can place demands on building services beyond those of ordinary office equipment. A lab plan therefore needs to consider what services the intended work requires and whether the building can accommodate equipment changes. NIH predesign guidance recommends spare capacity in utilities so researchers can add equipment and instrumentation, and describes flexibility as a way to accommodate evolving research and technology.
NIH’s Design Requirements Manual gives the rationale directly: “Flexibility and adaptability ensures that a laboratory can meet evolving research needs and functional changes, and accommodate changing technologies in scientific procedures.” This is a planning principle, not a promise that every room can support every future use. A change in research may alter utility demand, equipment layout or safety needs, so flexibility has to be considered alongside the systems and constraints of the particular facility.
Designing for change means considering more than whether a room has enough open floor area today. Future equipment may need different services or a different arrangement, and those changes can affect the surrounding systems and safe operation. Spare capacity and adaptable infrastructure can make some changes easier to accommodate, but they do not remove the need to review the proposed work and its requirements.

Layout connects work, safety and circulation
Laboratory space has to accommodate work surfaces and instruments without compromising access to safety equipment, circulation or exits. A room plan should account for how people move through it, where activities occur and how equipment will be serviced or brought in. Where containment devices are used, their placement has to work with both the room’s airflow and the paths people need to use.
These are practical constraints, not just questions of convenience. A layout that leaves no suitable route for moving a large instrument or places a device in a circulation aisle may conflict with the intended operation of the space. Equipment location, egress and airflow therefore need to be considered together during planning, rather than resolved independently after the room is laid out.
Laboratory planning also considers the facility’s operational and security needs, not just its room-by-room geometry. The APHL/CDC Laboratory Facility Construction and Major Renovations Guidelines describes planning as multifaceted, taking account of safety, security, efficiency, cost, current and future research needs, and operating standards. The guide does not provide technical design requirements or detailed solutions for individual laboratory types; those depend on the specific project and its applicable standards.

1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsOffice and laboratory functions may coexist in one science building, but that does not mean they should be treated as the same kind of space. National Academies material on laboratory practice discusses separating office and laboratory areas. The appropriate arrangement depends on the facility and the work. A project team must determine how research, support and administrative functions relate, rather than assume that a desk area can be placed anywhere next to a lab without considering operations.
There is no single universal science-building specification
The design depends on the research activities, the hazards involved, the equipment, institutional policy and jurisdiction. A biological research space and a chemical laboratory can have different containment and ventilation needs; a computational research area may not need the same laboratory equipment at all. Even within a building, rooms can serve distinct purposes and therefore require different systems and arrangements.
Source documents also have defined scope. NIH’s Design Requirements Manual establishes technical and design policy, requirements, standards and criteria for NIH-owned, leased, operated and funded buildings. Its revision page identifies Revision 2.1 as dated August 2, 2024. That manual is NIH-specific, not automatically a code or design specification for every project; teams working on an actual building should establish which current rules and standards apply to their facility and jurisdiction.

Likewise, OSHA’s laboratory appendix is nonmandatory recommendations, and BMBL is biosafety guidance. These materials inform design decisions but do not remove the need for project-specific risk assessment and applicable requirements. The APHL/CDC construction and renovation guide expressly does not supply technical requirements for each laboratory type.
For an actual project, the distinction between guidance and governing requirements is important. A reference may explain design considerations without serving as the applicable code, and a manual written for one institution’s facilities does not automatically govern another institution’s building. Project teams need to identify the rules and standards that apply to their own location, institution and planned work, then use risk assessment to inform decisions that depend on the hazards involved.

For owners, researchers, architects, engineers and construction teams, the practical starting point is the work the building must support—not a generic lab layout. The intended research, hazards, equipment and operating needs shape the infrastructure and the plan. That makes early coordination valuable: room arrangements, utility capacity, ventilation, equipment access and future flexibility can affect one another.
- Define the work: identify research activities, procedures and relevant hazards before settling on a room type or equipment list.
- Identify the controls: determine which ventilation arrangements, fume hoods, BSCs or other measures are appropriate to the actual work and risk assessment.
- Plan services and capacity: account for equipment requirements and consider spare utility capacity for changes in instrumentation or research.
- Test the layout: coordinate benches and equipment with circulation, egress, containment-device placement and routes for moving large equipment.
- Establish the governing requirements: confirm the applicable jurisdictional rules, institutional policies and standards rather than assuming NIH guidance governs every project.
- Plan for operation: ensure staff understand the ventilation and exhaust equipment relevant to their work, and consider the energy implications of ventilation choices.
These planning considerations also help frame the project’s trade-offs. The construction and renovation guidance treats cost, efficiency, safety, security, future research and operating standards as interrelated concerns. Ventilation can have significant energy implications, while adding flexibility may support future changes. The sources cited here do not establish a universal cost premium or square-foot allowance for a science building, so those figures must come from project-specific estimates rather than a blanket comparison with offices.
The result is not merely an office building with laboratory furniture added. It is a facility whose laboratory spaces and building systems are matched to defined research activities, risks and operational needs, while its office and shared spaces can still serve the familiar functions of a workplace.
Frequently Asked Questions
Does every science building need fume hoods or biological safety cabinets?
No. Hoods and BSCs are selected for the hazards and procedures in the spaces where they are needed. Chemical fume hoods protect personnel from chemical hazards; BSCs, used with appropriate practices, procedures and administrative controls, provide primary containment for potentially infectious microorganisms.

Are all laboratories designed to be under negative pressure?
No universal pressure arrangement applies to every laboratory. OSHA’s nonmandatory chemical-hygiene recommendations discuss pressure relationships, but the appropriate ventilation and pressure approach depends on the work, hazards, facility and applicable requirements.
Can a standard office be converted into a laboratory by adding benches?
Not necessarily. A laboratory may need ventilation, specialized utilities, containment equipment, safe circulation and routes for moving instruments. Whether an office can be adapted depends on the intended research, hazards, existing building systems and applicable requirements.
Does NIH’s Design Requirements Manual apply to every science building?
No. The manual establishes requirements and criteria for NIH-owned, leased, operated and funded buildings. Other projects must determine which jurisdictional rules, institutional policies and standards apply to them.

Research methods and instruments can change. NIH predesign guidance recommends spare capacity so researchers can add equipment and instrumentation, and flexibility can help accommodate evolving research and technology. It does not mean every room can support every future use.
The Bottom Line
A science building differs from a standard office because its laboratories must support research processes, equipment and hazards—not just desks and meetings. Ventilation, containment, utilities, circulation and adaptability should be matched to the work, with project-specific requirements established through risk assessment and applicable standards.
