Full title and description

STB VDI 2054 2019-08 — Ventilation and air conditioning — Data processing (VDI Ventilation Code of Practice). Guidance for the planning, installation, commissioning and operation of ventilation and air‑conditioning systems for spaces used for data processing and computing centres (bilingual German/English publication).

Abstract

The guideline addresses the specific thermal loads, air‑handling requirements and energy‑related planning principles for rooms and areas that house IT equipment. It provides models and calculation methods for total cooling load, supply‑air volume flow and exhaust temperatures; an equipment/system selection framework; availability (redundancy) classifications; and checklists for load and fault tests. The recommendations focus on unmanned machine rooms and on minimising energy demand of the technical installations that condition IT rooms.

Scope

This VDI guideline specifies requirements and recommendations for the planning, erection and operation of ventilation and air‑conditioning systems for data processing rooms and computing centres. It covers system selection, design parameters and dimensioning, availability classes for HVAC and cooling, technical acceptance, operation, maintenance and documentation. The document applies to unmanned machine rooms (spaces without permanent workstations) and does not cover direct chip‑ or rack‑level liquid cooling methods at the processor core.

Key topics and requirements

• Cooling load calculation methods and models for IT installations (total heat load, sensible/latent partitions, exhaust temperature predictions).
• Supply‑air volume flow and air distribution design principles specific to data halls and equipment rooms.
• System selection guidance: air‑based vs. other cooling strategies, media and refrigerant considerations, integration with building automation.
• Availability and reliability: classification of availability/redundancy for climate and cooling systems, and related operational requirements.
• Operational procedures, commissioning, technical acceptance criteria and checklists (load test and fault/test checklists included as annexes).
• Safety, fire‑protection and building‑technical requirements relevant to HVAC installations in data processing facilities.
• Energy efficiency considerations and guidance to minimise energy demand of conditioning systems for IT spaces.

Typical use and users

Used by HVAC and building services engineers, data‑centre planners and designers, facility managers, installers and system manufacturers, and project owners. Typical applications include design and commissioning of data halls, planning of redundancy and availability strategies, acceptance testing and operational procedures for server rooms and colocation facilities.

Related standards

References and related documents commonly cited with VDI 2054 include DIN EN 16798 (indoor environmental and energy performance standards), VDI 4700 Part 1 and other VDI ventilation rules and VDI handbooks on room air technology; the guideline also cross‑references relevant DIN/EN standards for hygiene, fire protection and building services.
