Laboratory design works best when it starts with your facility’s actual science, hazards, people and future plans—not with a fashionable room layout. The eight strategies below provide a practical way to set priorities: create a satisfying workplace, combine fixed and flexible elements, protect people and information, reduce energy demand, control sensitive environments, use space carefully, choose a site that supports future operations, and manage public access. No single strategy ranks first for every laboratory. A clinical testing lab, teaching lab, research suite and high-containment facility will make different trade-offs, and each decision must be checked against applicable codes, biosafety requirements and engineering analysis.
The framework draws on Nate Roisen’s eight-strategy guidance, the NIH Design Requirements Manual Revision 2.1, and laboratory sustainability guidance from the Whole Building Design Guide. Use it to structure an early briefing with your architect, laboratory planner, engineers, users and safety professionals.

What should be decided before a laboratory is designed?
Begin with a concise project brief that turns scientific and operational needs into design information. Record the processes performed, samples and chemicals handled, hazard classifications, contamination controls, instruments, staffing by shift, hours of operation, deliveries, waste streams, visitors and security boundaries. Equipment and staffing data should arrive early enough to influence room dimensions, floor loading, electrical capacity, heat gain, ventilation and utility distribution.
Map the workflow from receipt through storage, preparation, analysis, decontamination and disposal. Mark clean and dirty routes, people and material flows, emergency exits, maintenance access and places where one activity could interfere with another. Agree on adjacencies before drawing a detailed plan: for example, sample receiving may need a controlled relationship to cold storage and preparation, while public areas should be separated from technical circulation.

Finally, identify what must remain stable and what may change. A written list of fixed requirements and likely future changes prevents an expensive one-size-fits-all solution and gives the team a basis for comparing options.
How do I create a laboratory that satisfies the people using it?
A satisfying laboratory combines technical performance with a workplace that is comfortable, legible and easy to operate. Cleaning, durability, ergonomics and workflow remain essential, but daylight, views, finishes and personal control can affect whether staff can work effectively over long shifts.

Design for comfort without compromising science
- Daylight and windows: use them where they support wellbeing and orientation, but check glare, heat gain, thermal stability, privacy, instrument sensitivity and blackout requirements. NIH guidance cautions that windows must be balanced against equipment and research conditions.
- Ergonomics: set bench heights, reach zones, sink locations, seating and monitor positions around the tasks people actually perform. Provide accessible routes and work points rather than treating accessibility as an afterthought.
- Finishes: select surfaces that tolerate the chemicals, disinfectants, abrasion and moisture present in the room. A visually attractive finish that cannot withstand the cleaning regime is not a successful choice.
- Visibility: internal windows or carefully placed views can improve supervision and orientation, provided they do not expose confidential work or compromise containment.
- Personal control: where the engineering design allows it, give occupants practical control over task lighting, local storage and reasonable thermal settings. Controls should not defeat required pressure relationships or ventilation.
The right question is not “How much glass or daylight can we add?” but “Where do environmental quality and scientific stability reinforce each other?” Model the answer room by room.
How do I make a lab more flexible without overspending?
Flexibility is valuable when a room’s work is likely to change, but it carries a cost premium. Apply it selectively instead of making every surface movable. The NIH manual states that “Laboratory areas shall be reconfigurable without major alterations to the utility systems,” while also qualifying flexibility as a practical design decision.
Match adaptability to the operation
- Use adjustable shelving, mobile cabinets or modular casework where equipment and storage needs are expected to shift.
- Keep fixed infrastructure—such as drains, exhaust connections, heavy equipment supports or specialized containment—where moving it would add risk or cost without operational benefit.
- Provide accessible utility zones, spare capacity where justified, and ceiling or service layouts that permit future connections without major demolition.
- Separate replaceable furniture from building systems so a new bench or instrument does not trigger a reconstruction project.
Compare each flexible feature with its initial cost, maintenance burden, cleaning requirements, stability and effect on usable floor area. A highly mobile layout can be counterproductive in rooms that need vibration control, strict segregation or fixed process lines. Document which areas are intended to change and which are deliberately permanent.

How should laboratory safety and security shape the plan?
Safety and security should define circulation, zoning and access from the start. Set boundaries according to hazards, containment, regulations and operational needs; an open plan is not automatically safer.
Build a risk-based access model
- Classify spaces: distinguish public, staff, controlled, restricted and high-hazard areas. Identify who needs routine, occasional or emergency access.
- Assign credentials: align badge levels and visitor permissions with the work performed, not simply with job titles.
- Protect transitions: design vestibules, change areas, hand-washing points and material pass-throughs where the hazard assessment requires them.
- Plan for 24/7 arrival and departure: review parking distance, exterior lighting, sightlines, access-control reliability and emergency communication for staff working early, late or alone.
- Preserve service access: maintenance personnel need safe routes that do not require unnecessary entry into sensitive or occupied work zones.
Containment, hazardous materials, confidential research or regulatory separation may require enclosed rooms and controlled circulation. Public visibility should never override a documented need for separation. Coordinate the architectural plan with fire protection, industrial hygiene, biosafety, security and applicable authorities having jurisdiction.
How can a laboratory be more energy efficient?
Reduce energy demand by right-sizing the building and mechanical systems to actual staffing, equipment, ventilation and operating schedules, then evaluate recovery and renewable options without weakening safety or experiment integrity. Laboratories often use more energy than ordinary offices because of high ventilation rates, containment and exhaust devices, heat-generating equipment, long operating hours and backup systems.
Prioritize measures in the right order
- Right-size first: use verified equipment heat loads, occupancy patterns and room functions rather than generic allowances.
- Control airflow intelligently: coordinate pressure relationships, air-change requirements, hood operation and occupancy controls with the hazard assessment.
- Recover energy where appropriate: assess heat recovery and other reuse strategies for compatibility with exhaust chemistry, contamination control and maintenance.
- Evaluate site systems: geothermal and solar systems may be suitable in some projects, but their value depends on climate, site conditions, capital cost, maintenance and available space.
- Commission and monitor: verify that installed systems deliver the required airflow, pressure, temperature, humidity and control sequences before occupancy, then maintain them through operations.
In the 2025 Building Design + Construction article, Roisen cites approximate examples of facilities using geothermal and solar systems at about 100 kBtu/sf/year or less, compared with roughly 300–400 kBtu/sf/year for facilities with traditional mechanical systems. These are author-reported examples, not guarantees or a universal benchmark. The WBDG sustainable laboratory guidance provides broader context for reducing energy and water use while maintaining laboratory performance.
Energy measures must preserve indoor air quality, worker safety, containment and the integrity of experiments. The ASHRAE Laboratory Design Guide, Second Edition covers airflow, exhaust hoods, energy recovery, commissioning, biological containment, sustainability and life-cycle costs for teams needing specialist reference material.

What is required for a sensitive laboratory environment?
Highly sensitive testing requires control of materials, airflow, vibration, temperature, humidity and workflow. The more sensitive the measurement, the less tolerance there is for uncontrolled contact, particulate transfer or instrument interference. Roisen describes testing capabilities reaching parts per trillion in some contexts; that does not mean every instrument or method has that detection limit.
Control contamination at the source
- Choose materials deliberately: specify low-shedding, cleanable and chemically compatible surfaces, sealants and furnishings.
- Use dedicated instrument rooms: isolate equipment from traffic, vibration, heat and airborne contaminants when its method requires a stable environment.
- Separate clean and dirty processes: make the direction of movement obvious and avoid routes that force contaminated materials through clean work.
- Adopt unidirectional workflow where justified: arrange receipt, preparation, testing and disposal so samples and personnel do not backtrack across control boundaries.
- Define environmental criteria: document temperature, humidity, pressure, cleanliness, vibration and electromagnetic requirements with the instrument and scientific teams.
Do not add cleanroom features by default. They increase capital, operating and maintenance demands; use them where the test method, hazard assessment or quality system demonstrates a need.
How do I do more laboratory work in less space?
Space efficiency comes from agreeing on the program and workflows early, not from squeezing every bench into the smallest possible footprint. A smaller plan can become more expensive if it creates bottlenecks, unsafe storage, inaccessible equipment or future rework.
A practical space-program sequence
- List activities and instruments: include dimensions, clearances, service connections, heat output, access for replacement and maintenance.
- Map adjacencies: place rooms according to sample, staff, waste and service flows rather than department names alone.
- Set occupancy assumptions: record staffing by shift and distinguish dedicated workstations from shared areas.
- Test alternatives: compare shared equipment, centralized support rooms, modular storage and multipurpose rooms against turnaround time and contamination risk.
- Protect expansion paths: reserve logical locations for additional instruments, utilities and circulation before finalizing the footprint.
Roisen reports that laboratory projects in 2025 were estimated at 50–75% higher cost than comparable pre-COVID projects because of workforce shortages and higher labor, material and transportation costs. That is the author’s estimate, not a universal construction-cost statistic. Early scope agreement and disciplined room data are therefore financial controls as well as design tools.
How should I select a laboratory site for future operations?
Choose a site for the laboratory you expect to operate and expand, not only the one you can fit today. Zoning, utilities and transportation are necessary but incomplete criteria.

Evaluate incoming power, emergency power, water quality and quantity, waste handling, exhaust discharge, loading, telecommunications, security and emergency response. Then consider shared resources, collaboration with nearby agencies or departments, co-location opportunities and the physical route for a future addition. A site that supports partnerships or shared specialized equipment may deliver more value than one with a lower initial cost but no expansion path.
Include staff safety in the site decision: examine parking, transit, pedestrian routes, lighting, weather exposure and after-hours access. Record assumptions about growth and revisit them before property acquisition or a major lease commitment.
How do you balance laboratory safety with public access?
Public engagement can strengthen trust and education, but visitors must be kept away from hazards, confidential work and contamination-sensitive routes. Plan public circulation as a separate system rather than allowing tours to improvise through operating laboratories.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsDesign a controlled visitor experience
- Place reception, briefing and viewing areas before controlled access points.
- Use glazing, cameras or curated displays to show work without exposing samples, screens or restricted equipment.
- Provide a defined tour route with doors, barriers and supervision appropriate to the risk assessment.
- Keep visitor toilets, coat storage and waiting areas out of clean or hazardous process paths.
- Set rules for photography, personal protective equipment, escorting, emergency evacuation and tour cancellation.
Some laboratories should have no public route through technical areas. Security, containment, occupational hazards and research requirements can outweigh the benefits of visual openness. Reassess the arrangement whenever processes, hazards or visitor numbers change.

Frequently Asked Questions
What professionals should be involved in laboratory planning?
Bring laboratory users, an architect or laboratory planner, mechanical and electrical engineers, structural and fire-protection specialists, and the people responsible for biosafety, industrial hygiene, security and operations. The exact team depends on the hazards, regulations and scientific work, so appoint qualified specialists before the concept is fixed.
When should equipment information be provided to the design team?
Provide current equipment schedules and credible future allowances during programming, before room sizes and mechanical capacities are finalized. Include dimensions, service connections, heat output, vibration limits, delivery path and maintenance clearances; late changes can force redesign.
Do all laboratories need cleanrooms or dedicated instrument rooms?
No. These features are justified only when the method, contamination-control plan, instrument stability or hazard assessment requires them. Adding them without a defined need increases construction, energy and maintenance demands.
How can an existing laboratory be renovated while it remains operational?
Phase work around containment boundaries, critical equipment, shutdown windows and temporary routes. Confirm temporary ventilation, utilities, noise and vibration controls with the safety and operations teams, and establish a documented move-in and commissioning sequence before construction starts.
What reference can help engineers compare laboratory systems?
ASHRAE’s Laboratory Design Guide, Second Edition is a specialist reference covering planning, exhaust, airflow, energy recovery, commissioning, biological containment, sustainability and life-cycle costs. It complements—not replaces—project-specific codes, standards, biosafety review and engineering analysis.
