| Summary/Abstract |
Energy efficiency standards have crucial roles in reducing the energy consumption of room air conditioners (RACs) in many countries around the world. In this paper, a review of the policy rules of energy efficiency standards is presented. The characteristics and rationality for the evaluation metrics in various countries are analyzed. The difference between the energy efficiency standards for RACs in China and those for other countries are discussed. The development trends for the energy efficiency standards of Chinese RACs are provided in this paper. The division of temperature zones, various operation modes and the long-term performance of RACs should be considered when establishing the energy efficiency standards of RACs. Note that the improvement in the energy efficiency standards of RACs is a vital measure for energy conservation and environmental protection. Therefore, the environmental impact of the energy efficiency standards for RACs with refrigerants will become a major direction in the enhancement of future standards of RACs. Finally, two methods based on a logarithmic function and a linear function are proposed in this paper, which combine global warming potential (GWP) and energy efficiency evaluation metrics. This paper will significantly contribute to the formulation and revision of the energy efficiency standards of RACs and provide guidance to manufacturers of air conditioners.

| Summary/Abstract |
In Europe, buildings tend to be equipped with individual air conditioners, which constitute a fast growing electrical end-use. In this context, this study aims to assess the environmental impacts of European individual air conditioners and to analyse policy strategies to reduce these impacts. After analysing the European context concerning individual air conditioners, the environmental impacts of European air conditioners are assessed using a Life Cycle Analysis approach. The following step consists in studying, both technically and economically, different improvement options aiming at reducing the environmental impacts of these appliances. These results, obtained at the product level, are then generalised at the European level and different policy measures are defined and analysed. The main conclusion is that the implementation of a Minimum Energy Performance Standard based on Least Life Cycle Costs could save up to 49 TWh and 20 MtCO2-eq in 2020 and be economically beneficial to the European end-user.
