Design and research on energy-saving and low-carbon renovation of old office buildings

With the increasingly severe global climate change and environmental issues, energy-saving and low-carbon have become important development directions in the construction industry. Most old office buildings are high energy comsumption buildings. As one of the important sources of energy consumption and carbon emissions, their energy-saving and carbon-reduction capabilities after renovation are particularly crucial. This paper elaborates on the development of policies and standards, and analyses the technical paths for energy-saving and low-carbon renovation of buildings. Taking the renovation project of the research building C of Beijing Institute of Architectural Design as an example, it presents the design and research methods for the energy-saving and low-carbon renovation of old office buildings. This project is the first renovation project of an existing building to meet the near-zero energy consumption standard after the implementation of theTechnicalstandardfornearlyzeroenergybuildingsin China. It has been in normal use for more than four years after renovation, with an annual energy-saving rate of over 60%. It provides a new idea for the low-carbon and green renovation of existing old office buildings.
