Refining estimates of air conditioning energy consumption in Asian countries: stock volume and energy efficiency labeling and standard

Abstract

In order to evaluate how the standard and labeling program for energy efficiency reduces energy demand in an economy, we must know how many appliances work and the total energy consumption capacity developed before and after the introduction of the program. This paper calculates the stock of air conditioners and its total electricity consumption capacity based on GfK market survey and collected data by authors. The results show that Japan has experienced a substantial reduction of electricity demand from air conditioning overall in the economy. However, Thailand and China maintain their average electricity consumption levels, but are unable to reduce total demand. A study of the energy efficiency standard-labeling mechanism development and market outcomes reveals that Thailand and China fail to continuously improve energy efficiency, although the mechanism curbed the increasing inefficiency. This implies that China’s and Thailand’s mechanisms need to raise the upper bound of the distribution of energy efficiency.
