ASHRAE and the United Nations Environment Programme (UNEP) OzonAction have released the Assessing RAC Plant Sustainability checklists and guidance sheets. These free, downloadable, easy-to-use tools are designed to help Refrigerating and Air-Conditioning (RAC) plants improve performance, reduce emissions and promote energy-efficient, sustainable operations.
Proper maintenance and operation of RAC plants remain a significant challenge due to increasingly complex systems, evolving technologies, and the introduction of new refrigerants requiring specialized knowledge and handling. The Assessing RAC Plant Sustainability tools provide practical support in addressing these challenges.
Explaining the utility of these tools, ASHRAE President (2025-26) Bill McQuade, P.E., CDP, Fellow ASHRAE, LEED AP, said, “These tools provide practical guidance that connects design intent with operational outcomes. 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.”
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. Explore the full suite of resources through the ASHRAE UNEP Portal.
