Key Points

This report provides an overview of seasonal AC energy-efficiency metrics, assesses the regional climatic conditions in ASEAN countries, and make recommendations for adopting ISO standard 16358 in a harmonised way across the region.

It explores ASEAN-specific temperature profiles, the United for Efficiency (U4E) Model Regulation Guidelines’ temperature bin hours, as well as ISO 16358 temperature bin hours to evaluate the efficiency of ACs. The results show the superiority of CSPF over the traditional energy-efficiency ratio (EER) metric for capturing the higher seasonal efficiency of variable-speed ACs.
