Technical seminar on smart building energy management systems
By Ir Mannix M W CHAN and Ir Sally S Y LEUNG
The BS Division held the captioned seminar for a full house of engineers right after its Annual General Meeting on 25 April 2019. The speakers were Ir Paul C F Chan from CLP Power Hong Kong Ltd and Ir Stanley Y W Lam from CLPe Solution Ltd. The objectives of the seminar were to promote energy savings through the introduction of smart building energy management system (SBEMS) and to increase the awareness of combating climate change and reducing the carbon footprint of buildings.
The first part of the seminar was presented by Ir Lam. He started by explaining the technology behind SBEMS, which is a cloud-based platform backed-up by a proprietary artificial intelligence engine to perform data analytics and deliver intelligence by acquiring live data from the internet of things sensors, equipment, and systems. He then elaborated on how SBEMS can enhance the management and maintenance efficiency of buildings by automating time-consuming and labour-intensive processes through machine learning.
After that, Ir Chan discussed application of SBEMS at the CLP Sham Shui Po Centre (SSPoC). He listed out all the existing building management system limitations in the SSPoC such as no alert signals, the periods required to investigate defects and the lack of energy consumption analysis in daily operations. He also discussed how facility managers are hindered by these limitations, thus resulting in low effectiveness in managing energy use.
In order to overcome these limitations, a pilot trial of the SBEMS was conducted in the centre. Ir Chan explained the different stages of the project and the processes involved in each stage. The performance of SBEMS was assessed based on four major criteria: energy saving, customer satisfaction, system reliability and productivity enhancement. Ir Chan said that the pilot trial proved successful both technically and commercially.
Finally, the participants actively exchanged views on SBEMS. It was an inspiring sharing session for engineers to consider adopting SBEMS in the future. We would like to express our sincere thanks to the speakers and participants for making this event successful.
