32nd IIR Informatory Note: Harmonization of Life Cycle Climate Performance Methodology



In 2012, the International Institute of Refrigeration (IIR) set up a Working Group in order to assess the merits of the Life Cycle Climate Performance (LCCP) methodology.


The Working Group developed guidelines for performing LCCP calculations for air-conditioning and refrigeration systems with recommended assumptions and data sources for different types of units.

These guidelines provide a harmonised method to calculate the LCCP for all types of stationary air-conditioning and heat pump systems.

They aim to provide designers, facility operators and manufacturers a way to effectively evaluate and compare the environmental impact of different systems over the course of their lifetimes.




Recommendations and data sources


This Informatory Note summarises the LCCP guidelines prepared by the Working Group.

It provides recommended assumptions and data sources for different types of units, presents the various existing LCCP tools and outlines usages and limitations of LCCP.

The LCCP is a holistic metric for quantifying the environmental impacts of HVAC&R units over their lifetime and should be an essential tool in the future selection, development and implementation of these units.


This Informatory Note was prepared by Yunho Hwang, Chairman of the IIR Working Group “Life Cycle Climate Performance Evaluation” and was reviewed by several IIR experts.
