ASHRAE/UNEP launch sustainability assessment tools
31st July 2025
USA: ASHRAE and the United Nations Environment Programme (UNEP) OzonAction have released new checklists and guidance sheets to support RAC equipment performance, compliance and sustainability.
The Assessing RAC Plant Sustainability checklists and guidance sheets are free-to-download, easy-to-use tools designed to help refrigerating and air conditioning plants improve performance, reduce emissions and promote energy-efficient, sustainable operations.
Proper maintenance and operation of RAC plants is seen to remain a significant challenge due to increasingly complex systems, evolving technologies, and the introduction of new refrigerants requiring specialised knowledge and handling. The Assessing RAC Plant Sustainability tools provide practical support in addressing these challenges.
“These tools provide practical guidance that connects design intent with operational outcomes,” said 2025-26 ASHRAE president Bill McQuade. “By helping RAC professionals assess and improve sustainability across key performance areas, we’re empowering the industry to make data-informed decisions that benefit the environment, their workforce and their bottom line.”
Originally designed for field technicians, the tools also offer value to plant managers, equipment suppliers and consulting engineers.
The guidance also includes recommendations for energy-efficient operation, life-cycle investment considerations and key performance indicators to help determine when equipment upgrades are warranted.
This resource is part of a broader portfolio of ASHRAE-UNEP tools developed to promote responsible, efficient cooling practices and support international efforts related to the Montreal Protocol.
