How to Write a Cold Storage Requirements Document Suppliers Cannot Twist
A vendor-neutral template and worked example for the single most valuable artefact in any industrial refrigeration project — a requirements document precise enough that two independent engineers would produce comparable designs from it.
The most expensive line item in a cold storage project is rarely the compressor, the panels or even the land. It is the missing requirements document. When buyers go to market without one, every supplier writes their own version of the project, prices it on their own assumptions, and the buyer ends up comparing quotes that look similar but describe fundamentally different facilities. This article distils the requirements framework introduced in the pillar guide on planning before equipment into a working template you can send to your engineering team today.
What a requirements document is (and is not)
A cold storage requirements document is not a wish list, not a marketing brief and not a data sheet. It is an engineering specification, written by or for the buyer, that defines the project in enough detail that competing designers arrive at comparable technical answers. It exists before any refrigeration brand, EPC or panel supplier is invited to quote.

Why generic templates fail
Most templates online are written by manufacturers. They emphasise the fields the manufacturer's configurator can price, and quietly omit the fields that would allow a buyer to compare two rival architectures. A serious requirements document treats refrigerant, controls and envelope as open technical questions — not as pre-decided answers.
