Summary

Climate change is an increasingly important global concern with far reaching effects. The heating, ventilation, air conditioning and refrigeration (HVAC&R) industry is allotting a significant amount of effort to reduce the environmental impacts of HVAC&R systems. Discussions about the climate impact is often limited to the GWP of the fluids used, but this is far too restrictive, as it does not take into account the real emissions of fluids and ignores indirect emissions, especially those related to energy use over the life time of the equipment. Focusing solely on GWP can lead to irrational and counterproductive decisions. This is why it is so important to use more comprehensive indicators of the real Green House Gases emissions of systems over their life time.
Additional holistic indices have been developed to measure this impact, including Total Equivalent Warming Impact (TEWI), Life Cycle Analysis (LCA) and Life Cycle Climate Performance (LCCP). However, these indices are still not widely used. The International Institute of Refrigeration (IIR) established a working group in January 2012 to assess the merits of the LCCP methodology [1] and to propose evaluation methods to promote the use of the LCCP index. The working group developed this guideline and an abbreviated guideline for performing LCCP calculations for air conditioning, heat pumping and refrigeration systems with recommended assumptions and data sources for different types of units.  
This guide provides a harmonized method to calculate the LCCP for all types of stationary air conditioning, heat pumping and refrigeration systems. The process and assumptions by which LCCP should be approached are discussed in later chapters. This guide aims to provide designers, facility operators, manufacturers and policy makers a way to effectively evaluate and compare the environmental impact of different systems over the course of their lifetimes. A sample calculation and excel tool are included for a residential heat pump.
