The "open access" double carbon target has been one of the most important motivations and goals for China's social and economic development. Building is one of the most important sector for achieving energy savings and emission reductions. This book focuses on China’s building energy usage and CO₂ emissions to discuss the status quo of China’s building energy usage in four categories, their characteristics, and technologies to improve energy efficiency and achieve zero-carbon emissions. Specifically, it discusses pathways to achieving China’s carbon neutrality target for the urban residential building sector. It also analyzes the energy mix, energy intensity, and technological approaches for implementing energy and carbon targets. This book consists of large-scale survey and monitoring data, as well as case studies. The discussions of technologies and policies are supported by a variety of evidences and continuously researches results for more than ten years. The information, data, and policy suggestions will be of interest to domestic and international audiences working in the areas of energy, climate change, engineering, and building science.

Yi Jiang is Professor and Head of the Building Energy Research Center, Tsinghua University, and a member of the Chinese Academy of Engineering. He has been involved in a number of international collaboration projects such as IEA EBC (International Energy Agency Energy in Buildings and Communities) Annex 21, 25, 34, 53 and 59. He is also a member of China’s Energy Advisory Committee under the State Council, and a member of China’s Climate Change Advisory Committee. His major research field is building energy efficiency and low carbon buildings. He is the chief editor of the Annual Progress Reports of Chna Building Energy Efficiency, among many other publications. He received four Chinese national science awards for controls of district heating system, liquid desiccant air-process, indirect evaporative cooling, and building energy simulation (DeST).

Dr. Shan Hu is an assistant profressor of Tsinghua University. Dr. Shan Hu graduated from Tsinghua University in 2018, worked in the Building Energy Group of the International Energy Agency in 2018, and joined the Building Energy Research Center of Tsinghua University in 2020. She is engaged in modeling and policy research related to building energy and climate change. Her main research results include "Annual Development Research Report on Building Energy Efficiency in China", "China Building Energy Use", "Building energy use in China" (joint report with IEA), "The future of cooling in China" (joint report with IEA (joint report with IEA) and articles in English and Chinese, which are important reference materials for domestic and international understanding of energy consumption and emissions in China's building sector. Currently, Shan Hu is also the chapter scientist and contributing author of the Sixth Assessment Report of the United Nations Intergovernmental Panel on Climate Change (IPCC).
