Does this replace a facilities review?

No. It creates a quote-ready starting point. Electrical service, HVAC, access policy, and backup plans still need review.

Why add a free-space buffer?

The buffer prevents immediate overfilling after installation and leaves room for incoming boxes, audits, and sample cleanup.

Do not use for

Validated clinical cold-chain compliance or manufacturer-specific performance qualification

Keep spare capacity real

A full freezer is hard to audit and warms faster during access. Preserve empty slots for incoming samples.

Temperature is only one input

Access policy, ownership, backup power, and inventory discipline can change the right freezer class.

Method

The selector projects current box count by expected growth, adds a 15% free-space buffer, maps temperature band to freezer class, then estimates units from typical boxes per cubic foot. Accessories and specs are rule-based planning prompts, not manufacturer-specific claims.
