Data Center HVAC Peer Review Manual: A Structured Review Framework for Consulting Engineers

This manual is a working reference for consulting engineers performing peer review of data center HVAC designs at the schematic, design development, construction document, and pre-issue-for-construction stages. It is organized to support both a formal, documented peer review process and informal self-review by the design team prior to submission.

The core of the manual is a bank of 500 design review questions organized into ten technical categories that mirror the typical scope of a data center HVAC design: cooling load and capacity planning, CRAC/CRAH selection, chilled water plant design, heat rejection, airflow management, piping, humidity control, controls and BMS, redundancy and fault tolerance, and commissioning/code compliance. Each question is written to be answerable as Yes, No, or Not Applicable, with space for reviewer comments, and can be used directly as a checklist during a review meeting or issued electronically for distributed review.

The remaining chapters address the review themes that cut across every technical category: common design mistakes seen repeatedly across projects, coordination issues between disciplines, constructability, energy efficiency, reliability, and maintainability. These chapters are intended to be read once as a reference and consulted again whenever a specific issue is encountered during review.
