At the E&M AI Lab Tech Talk, the EMSD introduced the E&M Agent, a new artificial intelligence (AI) assistant for building E&M facilities. The E&M Agent enhances maintenance efficiency through features such as fault diagnosis and data comparison of various chillers.
The EMSD hosted the E&M AI Lab Tech Talk in March 2025 to share the development of semantic artificial intelligence (AI) and application of AI assistant with the trade.
(Left) By adopting the Multi-trade integrated Mechanical, Electrical and Plumbing approach, the EMSD assisted the Pamela Youde Nethersole Eastern Hospital in replacing the air-cooled chillers and connecting a new chilled water piping system to the existing operating theatre floors. This approach not only accommodated the site constraint of prohibited hot work on the existing helipad but also shortened the on-site construction time, thereby mitigating the impact on hospital operations.
(Right) Building Information Modelling technology was adopted to develop the model of chiller system, effectively enhancing works quality.
The EMSD installed an advanced new chiller at Wang Cheong Building using Building Information Modelling (BIM) and the Multi-trade integrated Mechanical, Electrical and Plumbing technologies. This approach streamlined the construction process, reducing the number of working days and enhancing work efficiency. The new chiller has higher energy efficiency as compared with the traditional model.

(Left) We continued to install the Intelligent Fall Detection System in multiple Leisure and Cultural Services Department (LCSD) recreation and sports venues this year. Enhanced with voice recognition and display screens, the system helps detect potential accidents, and promptly alerts duty personnel in case of anomalies.

The EMSD has introduced the Smart Fence Protection System for the Hong Kong Police Force (HKPF) to strengthen border security. The existing closed-circuit television and vibration alert systems have been comprehensively upgraded, with new features such as licence plate recognition, data analysis and emergency assistance. Using artificial intelligence for intrusion detection, the system has enhanced the operational efficiency of the HKPF.
In collaboration with the Chinese University of Hong Kong, we piloted the real-time drone surveillance system at the Wo Hop Shek Cemetery under the Food and Environmental Hygiene Department, as a replacement for manual patrols. The system enables site staff to conduct 360-degree panoramic inspections, so as to enhance the security of the premises.
To enhance underground work safety, the EMSD introduced quadruped robots to assist the Drainage Services Department in patrol duties. Equipped with cameras and sensors, the robots can traverse uneven and rugged terrains while providing real-time videos, sensor data and information on hazardous gas levels.
To ease the physical burden on frontline street cleaning staff, the EMSD has introduced a cleaning robot for the Food and Environmental Hygiene Department. The robot, which can be operated via programmed routes or manual remote control, is now on trial near the Ma Liu Shui Waterfront.
