(b) Accelerating building energy efficiency improvement We will work faster to update standards in fields such as building energy efficiency and municipal infrastructure, instituting higher requirements for saving energy and reducing carbon emissions. We will step up the R&D and application of energy-saving and low-carbon technologies that can be used in various climatic regions and for different buildings in order to develop ultra-low-energy consumption and low-carbon buildings on a large scale. We will speed up renovation of residential and public buildings to achieve energy efficiency and continue to advance energy-saving and carbon-cutting upgrades of heating pipe networks and other municipal infrastructure. We will increase the intelligence level of managing the operations of urban buildings and infrastructure. We will move more quickly to expand the use of metered charging for heating and energy performance contracting, and gradually set energy consumption caps for public buildings. By 2025, all newly constructed buildings in urban areas will meet green building standards. (c) Accelerating the optimization of building energy consumption structure
