Below is a non-exhaustive list of valuable reports that the working group has relied on when becoming familiar with storage testing. “Electric energy storage – future storage demand” by International Energy Agency (IEA) Annex ECES 26, , C. Doetsch, B. Droste-Franke, G. Mulder, Y. Scholz, M. Perrin.
Are test procedures effective for room air conditioners?
Test procedures form the basis of effective MEPS programs and their consistency may offer benefits to policy makers, manufacturers, and consumers alike. This report is a comparative review of test procedures and efficiency metrics for room air conditioners across six countries, as well as the ISO standard.
How are heating and cooling efficiencies rated?
Full load heating and cooling efficiencies are rated using HCOP and CEER metrics, respectively. ACs and heat pumps are rated for SEER and HSPF metrics (for cooling and heating, respectively). The US also has a voluntary program, ENERGY STAR, aimed at identifying the most efficient equipment in each category.
