TEWI or LCCP indicators provide evaluations of total direct and indirect greenhouse gases emissions from cooling or HP (heat pump) systems. Yet, the results are awkward to use due to the variety of systems by capacity, technology, and operating conditions. This paper proposes steps toward standardized TEWI calculations. Many cooling and HP systems are subject to global or
regional standards, defining typical year-round operating conditions and rules for performance evaluation. Per the method proposed, input values for TEWI calculations are evaluated at standard operating conditions, with performance also evaluated per relevant standards. Results are presented as “specific TEWI”, in reference to the standards. The end result is simply the number of kilos of CO2 equivalent emitted over the life time, per kWh of cooling energy at standard operating conditions. Comparisons between systems are thereby made much easier, which should allow TEWI to become a more practical tool for decision making.
