Accelerated Renovation of Building Automation Systems in Existing Buildings, with Remarkable Green Operation and Maintenance Effects
Recently, the energy-saving renovation projects of existing buildings in various regions have been continuously promoted. The upgrading of building automation systems has become the core starting point. Through technological empowerment, the energy consumption of old buildings has been significantly reduced, taking into account both energy-saving benefits and operation and maintenance efficiency, and promoting the green development of the whole life cycle of buildings.
About 80% of the existing buildings in China are high-energy-consuming buildings. The aging and extensive regulation of traditional building automation systems lead to high energy consumption of core equipment such as air conditioners and lighting. In response to the requirements of the "14th Five-Year Plan for Building Energy Conservation and Green Building Development", various regions have increased their efforts in the renovation of existing buildings, focusing on promoting the intelligent upgrading of building automation systems, realizing the transformation from "extensive management" to "precision accounting".
As a benchmark case, Hong Kong Sun Hung Kai Building has upgraded Johnson Controls' METASYS CPO10 control system and E-cloud remote monitoring function, reducing annual energy consumption by 10%, carbon emissions by 300 tons, annual operating costs by 75,000 US dollars, and the investment can be recovered in 2 years. Commercial complexes and office buildings in many parts of China have also followed up. By integrating sensors and optimizing control logic, they have realized the coordinated control of air conditioning and lighting systems, with an average energy saving rate of more than 18%. Industry experts pointed out that the market potential for the renovation of building automation systems in existing buildings is huge. In the future, it will gradually extend to multiple scenarios such as hospitals and campuses, providing important support for the carbon peak in the construction field.
