Designing and fitting an effective laboratory involves more than just equipping it with the required technology; it involves thoughtful consideration of space and workflow to ensure safety and efficiency. From ensuring sufficient room for both equipment and researchers to specifying the right materials, every detail counts. This post explores ten key laboratory design considerations that are key to setting up a practical and modern facility.
1. Space Requirements
When it comes to effective laboratory design, the first key consideration should be the spatial requirements. Are you adapting an existing space, or are you setting up a completely new area? There should be sufficient room to house all necessary equipment and allow for researchers to operate comfortably and safely. In the vast majority of cases, the lab should also be fully enclosed for security and safety.
The specific needs of your laboratory can also influence space requirements. A biochem lab might need larger workspaces and room for floor-standing equipment, whereas an electronics lab might require less overall space but have particular needs regarding energy supply. It’s important to assess the immediate needs and plan for potential future expansion or changes in use to maintain its functionality over time.
2. Efficient Workstation Workflow
By positioning workstations to align with the sequence of tasks, labs can minimize unnecessary movements, vastly reducing time and energy spent on routine procedures. This setup should support the logical progression of activities.
For example, a biochemistry lab may streamline operations by logically structuring spaces from sample reception and storage, to sample analysis, followed by data analysis, and finally waste disposal. These procedures should be considered and reflected in the initial design of the space to ensure a smooth flow between activities.
3. Energy-Efficient Temperature and Lighting
When discussing laboratory design considerations, energy efficiency must be mentioned. Advanced HVAC systems with programmable thermostats offer precise temperature control, essential for energy conservation in areas requiring specific climate conditions. Regarding lighting, LED solutions are preferred due to their lower energy usage and longer lifespan, with converting to LED typically saving about 50% of the electricity used compared to fluorescent lighting. Another option is to maximise the use of natural light where possible, not only to reduce costs but also to keep the well-being of lab personnel in mind.

4. Signage and Graphics
Properly designed signs and graphics ensure that personnel and visitors can quickly identify safety equipment, understand hazard warnings, and follow operational procedures without confusion. Graphics should be clear, universally recognisable, and placed strategically throughout the laboratory to guide workflow and emergency responses. Incorporating braille and multilingual options where necessary is important for accessibility.
Beyond raw functionality, a well-designed and decorated lab also offers a positive and aesthetically pleasing working environment.
5. Security Systems
Effective security systems are a key laboratory design consideration. CCTV cameras can be fitted if constant surveillance is required, helping to deter unauthorized access and monitor sensitive areas around the clock. Door access control systems can restrict entry to authorized personnel only, using mechanisms such as key cards or biometric authentication. Together, systems like these ensure that both physical security and data protection standards are upheld, minimizing risks of theft or contamination.
6. Safe And Effective Ventilation
Appropriate ventilation systems will depend on the specific needs of the laboratory environment. In settings where chemical contaminants are present or where strict air quality standards must be met, mechanical ventilation such as air conditioners and exhaust fans must be installed. In cases where air quality standards are not necessary, natural ventilation through sufficient windows and general airflow considerations can suffice, giving an energy and cost-effective design.
The effectiveness of laboratory ventilation depends greatly on the overall fit-out, as it’s estimated that laboratories when equipped with furniture, instruments, and supplies can have their open-air volumes reduced by 15-20%, significantly impacting the effectiveness of calculated ventilation rates. Ventilation requirements should be assessed and overseen by professionals, with occasional assessments essential to maintain optimal air quality and energy efficiency in laboratory environments.
7. Waste and Chemical Storage
Any well-designed lab will require some degree of storage space – especially so if hazardous chemicals or waste is involved. Chemicals should be organized based on their compatibility to prevent hazardous interactions.
All storage units should be secure yet easily accessible to authorized personnel. Features like ground-level storage for heavy containers and secure shelving minimize the risk of spills and accidents. In one US study between 2001- 2018, chemical spills accounted for 69% of laboratory accidents, with the majority caused by inadequate handling of chemicals.
8. Cleanable Non-Porous Surfaces
To further reduce the risk of hazardous spills, flooring materials such as sealed vinyl, epoxy, or ceramic tiles are popular choices due to their non-porous surfaces that resist chemical absorption and simplify spill cleanup.
For countertops and workstations, materials like stainless steel, glass, and specially treated plastics are favoured for their ease of disinfection and resistance to harsh chemicals. All these materials also withstand frequent cleaning without degrading, ensuring a hygienic environment essential for scientific work.
9. Ergonomics and Comfort
As researchers can spend extended periods in the lab, ergonomics and ease of use should be considered. Adjustable workstations and chairs allow for a personalised fit that can prevent strain and injury. Proper lighting and comfortable workspaces also contribute to the well-being and productivity of lab personnel.
10. Fire Safety Considerations
A comprehensive approach to fire safety is important for any workplace, and this should be reflected in the design. From the selection of fire-resistant materials for benches and storage units to the strategic placement of fire extinguishers and safety showers, each element contributes to a safe environment.
Smoke detectors and fire alarm systems can be interconnected with the building’s main alarm system to allow for rapid response times and properly designed exit pathing and emergency signage help with quick evacuations.
