Summary

Life Cycle Climate Performance (LCCP) is an evaluation method by which heating, ventilation, air conditioning and refrigeration systems can be evaluated for the global warming impact over the course of their complete life cycle. LCCP is more inclusive than previous metrics such as Total Equivalent Warming Impact. It is calculated as the sum of direct and indirect emissions generated over the lifetime of the system “from cradle to grave”. Direct emissions include all effects from the release of refrigerants into the atmosphere during the lifetime of the system. This includes annual leakage and losses during the disposal of the unit. The indirect emissions include emissions from the manufacturing process, energy consumption, and disposal of the system. This paper proposes a standardized approach to the use of LCCP and traceable data sources for all aspects of the calculation. An equation was proposed that unifies the efforts of previous researchers. Data sources were recommended for average values for all LCCP inputs. An excel tool was developed for residential heat pumps using the proposed method. A residential heat pump sample problem is presented illustrating the methodology and the developed excel tool. The residential heat pump is evaluated at five U.S. locations in different climate zones. The primary factor in the LCCP calculation is the energy consumption of the system.
