Chinese Academy of Sciences Shanghai Laboratory Animal Facility Project Case Study: Cleanroom Envelope and Environmental Control Interfaces

Project Snapshot

A Multi-Discipline Animal Facility Package

The reviewed project folder identifies a Shanghai Chinese Academy of Sciences project with laboratory animal room drawings, South Building 2 animal-room documentation, wall-panel manufacturing data, cleanroom door data and a broader CAD package covering architecture, process, electrical, power/HVAC, water supply and drainage, fire protection and information/BA systems.

Cleanroom Envelope

Why Animal Facilities Need More Than Smooth Walls

Animal-room wall panels must tolerate repeated wiping, disinfection, impact from carts and cage equipment, and frequent traffic at doors and corners. The reviewed panel schedule for this project lists 50 mm handmade purification panels with 0.5 + 0.5 mm color steel sheet construction. The important engineering point is not the panel thickness alone; it is how the panels connect to doors, floors, ceilings, air grilles and service penetrations.

For a laboratory animal facility, cleanability and maintainability protect research conditions. A wall system should reduce ledges, exposed absorbent edges and uncontrolled gaps. Corners, skirting, observation windows and door frames should be planned together, because those interfaces become the first places where cleaning quality and room integrity are tested.

This project follows the same logic Wonclean uses for controlled cleanroom projects: coordinate the envelope before installation so that field teams do not need to improvise around room equipment, airside terminals or access control points.

Flow Control

Separate Personnel, Animals, Materials and Waste Routes

The Guide for the Care and Use of Laboratory Animals emphasizes that the facility environment should support animal care, sanitation and appropriate operation. From an engineering perspective, this means room layout, transfer routes and door locations must match how animals, cages, bedding, feed, clean supplies and waste move through the facility.

Wonclean's role in a project like this is to make the cleanroom envelope work with that flow. Cleanroom doors and observation windows help staff supervise rooms without unnecessary entry. Pass boxes or transfer interfaces help move materials without turning every room entry into a traffic point. Air shower and personnel-entry interfaces can help control particle carry-in where the project risk assessment requires it.

The project photos show controlled corridors with room doors, viewing windows and airside interfaces. Those elements should be interpreted as part of a route-control strategy, not as decoration.

HVAC and Monitoring

Animal Rooms Depend on Visible Pressure, Airflow, Temperature and Humidity Control

For animal facilities, HVAC is not only a comfort system. It supports pressure relationships, odor control, temperature stability, humidity stability and separation between functional zones. The project photos show an environmental monitoring panel with fields for pressure differential, air changes, supply airflow, exhaust airflow, temperature and humidity.

The displayed screen values are site-photo readings, not a universal specification. The engineering lesson is more important: animal facilities should make critical room parameters visible to operators so abnormal pressure or airflow conditions can be detected quickly.

ISO 14644-4 is relevant where the project includes cleanroom-style design, construction and start-up logic. Final acceptance should still be based on the owner's URS, local code, laboratory animal requirements and commissioning records.

Delivery Logic

Panel and Door Delivery Must Follow the Drawing Package

The project file set includes dedicated animal-room drawings, wall-panel schedules and cleanroom door documentation. That coordination is essential because animal facility rooms often combine many interfaces in a compact area: cleanroom doors, observation windows, ceiling terminals, lighting, low-wall return grilles, carts, sterilization equipment and room monitoring devices.

A panel system cannot be treated separately from the door schedule or HVAC plan. If a return grille, door swing, pass box or monitoring device is shifted during installation, cleaning access and pressure relationships may be affected.

Wonclean's project value is therefore in delivering a cleanroom wall and door package that can be checked against drawings before site installation. For laboratory animal rooms, this reduces the risk of field cutting, exposed joints and inconsistent sealing.

Technical Fact Check

What This Case Study Confirms

• The project folder identifies a Shanghai Chinese Academy of Sciences laboratory animal facility / animal-room project.
• The drawing package includes South Building 2 animal-room related CAD files, including animal-room dimension and South Building 2 7F-9F animal-room drawing references.
• The reviewed wall-panel schedule identifies 50 mm handmade purification panels with 0.5 + 0.5 mm custom white-gray steel sheet construction.
• Cleanroom door, clean fire-rated door and panel manufacturing / settlement documents are present in the project folder, but this article does not publish confidential quantities or contract values.
• The environmental monitoring values visible in the site photo are treated as photographed operating readings, not as universal design criteria.
• This article does not claim final room classification, animal species, biosafety level, SPF status or accreditation status; those items require owner-provided validation and regulatory records.
