With the rapid iteration and upgrading of artificial intelligence (AI) technology

its applications in the field of intelligent buildings have shown diversified and in-depth development trends. This paper systematically and comprehensively explores the current applications and future development trends of AI technology throughout the entire lifecycle of buildings

covering design

construction management

operation and maintenance

and energy optimization. Research indicates that the deep integration of AI with cutting-edge technologies such as the Internet of Things (IoT) and Building Information Modeling (BIM) is strongly driving the transformation of the construction industry towards intelligence and data-driven directions. Through analysis of typical cases

it is found that generative algorithms of AI in intelligent building design can increase design efficiency by 300%; During the construction phase

predictive maintenance can reduce equipment downtime by 40%; And in the operation and maintenance phase

energy optimization systems can achieve energy-saving effect of 20%-30%. Despite the numerous challenges currently faced

such as complex technical integration and lack of industry standards

AI technology is bound to become the core driver for achieving the "dual carbon" goals in the construction industry. In the future

the deep integration of AI and BIM will give rise to a new generation of intelligent construction platforms

further promoting the sustainable development of the construction industry.
