Full title and description

Cleanrooms and associated controlled environments — Part 16: Energy efficiency in cleanrooms and separative devices. This International Standard provides guidance and recommendations to optimise energy use and maintain energy efficiency in new and existing cleanrooms, clean zones and separative devices across multiple industries, addressing design, construction, commissioning and operation while aiming to preserve required cleanliness performance.

Abstract

The standard gives practical guidance for reducing energy consumption in cleanroom systems (HVAC, filtration, air change strategies, controls and separative devices) and introduces benchmarking concepts to compare cleanroom energy performance while maintaining ISO 14644 cleanliness requirements. It is applicable to a wide range of sectors including electronics, aerospace, nuclear, pharmaceutical, medical device, hospital and food applications.

Scope

ISO 14644-16:2019 provides guidance and recommendations to optimise energy usage and sustain energy efficiency in cleanrooms, clean zones and separative devices. It covers energy-related design choices (HVAC, filtration, air change rates, heat recovery and controls), commissioning and operational strategies (scheduling, setback/occupied modes, monitoring and maintenance), and benchmarking methodologies for performance assessment, with the objective of lowering energy consumption while maintaining the cleanliness and performance required by other parts of the ISO 14644 series. The standard is intended for both new builds and retrofits across multiple industries.

Key topics and requirements

• Principles and objectives for improving energy efficiency in cleanroom systems (balance energy reduction with contamination control).
• Energy-aware design guidance for HVAC, filtration, airflow patterns, pressure regimes and separative devices.
• Commissioning and validation practices that include energy performance checks alongside cleanliness verification.
• Operational strategies: scheduling, setback/unoccupied modes, variable air volume (VAV) approaches, demand-based control and maintenance to sustain efficiency.
• Benchmarking metrics and methods for comparing cleanroom energy performance while maintaining required ISO 14644 cleanliness levels.
• References to related energy-management standards (for example ISO 50001) and to other parts of the ISO 14644 series for cleanliness performance requirements.

Typical use and users

Intended users include cleanroom designers and consultants, HVAC and facility engineers, energy managers, validation and commissioning teams, pharmaceutical and medical device manufacturers, semiconductor and electronics manufacturers, hospital facility managers, and regulatory/compliance auditors seeking to reduce energy consumption without compromising controlled-environment performance. It is used during design, retrofit, commissioning and operational optimisation projects.

Related standards

ISO 14644-16 is part of the ISO 14644 series (Cleanrooms and associated controlled environments) and should be used alongside other applicable parts of that series (for example Parts 1–4, 8–15 and later parts for testing, monitoring and assessment). It also cross-references energy-management standards such as ISO 50001 and national/adopted variants (EN ISO adoptions). Practitioners commonly apply ISO 14644-16 together with the testing, monitoring and design parts of the series to ensure both cleanliness and energy objectives are met.

FAQ

Q: What is this standard?

A: ISO 14644-16:2019 is an international guidance standard that addresses energy efficiency for cleanrooms, clean zones and separative devices, offering recommendations for design, commissioning and operation to reduce energy use while preserving required cleanliness.

Q: What does it cover?

A: It covers energy-related measures for HVAC and separative devices, control strategies (including occupied/unoccupied modes and VAV), commissioning and maintenance practices, and benchmarking methods to assess and compare energy performance without degrading ISO 14644 cleanliness. It is advisory (guidance) rather than a prescriptive performance-only requirement.

Q: Who typically uses it?

A: Cleanroom designers, mechanical/HVAC engineers, facility and energy managers, validation/commissioning teams, production/manufacturing facility owners (pharmaceuticals, medical devices, microelectronics, aerospace, food, hospitals) and consultants focused on sustainability and cost reduction.

Q: Is it current or superseded?

A: ISO 14644-16:2019 is the first edition, published in May 2019 (24 May 2019). The ISO record shows the document as published and subject to the ISO review cycle; no newer ISO edition replacing ISO 14644-16:2019 was found at the time this summary was prepared (checked up to Feb 27, 2026). Users should verify the ISO catalogue or national adoption bodies for any later revisions or national adoptions before purchase or formal citation.

Q: Is it part of a series?

A: Yes — it is Part 16 of the ISO 14644 series (Cleanrooms and associated controlled environments). It is intended to be used in conjunction with other parts of the series that set classification, monitoring, testing, design and operational requirements.

Q: What are the key keywords?

A: Energy efficiency, cleanroom, separative devices, HVAC, benchmarking, commissioning, ISO 14644, energy management, retrofit, VAV, filtration.
