Decarbonize Urban Heating System

This is an open access book. The doublecarbon target has been one of the main motivations and goals for China's social and economic development. The building sector is one of the most important sectors to achieve energy saving and emission reduction. This publication thoroughly examines China's building energy use and carbon emissions with a focus on four categories, including their characteristics and the technologies needed to achieve zero carbon emissions.This year, the key issue is developing carbonneutrality pathways for China's urban heating system. This report comprehensively discusses the current status and future forecast of heat demand in buildings and nonprocess industries, introduces the challenges facing the urban energy supply system in achieving carbon neutrality, and elucidates the lowcarbon heating model based mainly on lowgrade and lowcarbon waste heat. Extensive survey and monitoring data and case studies are presentedthroughout the book. The discussion of technologies and policies has been the subject of extensive research and evidence for over a decade. The information, data, and policy recommendations are of relevance to a national and global audience working in the fields of energy, climate change, engineering, and building science.

The Building Energy Research Center (BERC) of Tsinghua University was founded in 2005. The mission of BERC is to be devoted to the development of energy-efficient, low-carbon and environmentally responsible buildings in China in accordance with national and international energy and environmental targets, including buildings research and innovation. The principal research activities within BERC include: Assessment of the current buildings status in China and the provision of strategic; outlooks on buildings energy consumption and efficiency; Occupant behavior and building simulation research; Research and development (R&D) of innovative high-efficiency buildings technology and systems; Energy efficiency application research on subsectors, including: space heating in Northern China; rural residential buildings; urban residential buildings; and public and commercial buildings.Since 2007, BERC has published annual report on China Building Energy Efficiency (in Chinese) to provide data references, technical and policy suggestions for policy makers and engineers in the field of building energy conservation and low-carbon transition. BERC is also involved in international exchange and cooperation, including on-going collaboration with the International Energy Agency. Since 2016, BERC has started to publish the English version of this report to publish the English version of this annual report to release the data and key findings for international researchers.
