The HKIE
webinar named “Combined Top-down and Bottom-up Approach in Facilitating
Innovation Projects” was co-organized by Civil Division and Building Services
Division and held on 7th Oct 2020.
The guest speaker was Mr. Cheung King Yip, Eric (Innovation Manager in
ATAL Engineering Group) and he shared ATAL iBS-Smart Energy Management Platform
firstly. He said big data in buildings
could be collected through sensor and equipment that would change the way we
managed energy. Then he briefed the ultimate
goals were HVAC optimization, fault detection & diagnostics, and data
visualization.
And then Mr. Eric Cheung briefed different modelling techniques including empirical model, physical model, machine learning model and physics-guided machine learning model (PGML) they employed. He said ATAL is the first to apply PGML in AC Control and successfully overcomes data-related issues. PGML employed that could overcome insufficient data.
After that he demonstrated different Fault Detection and Diagnostics (FDD) examples including Equipment Deterioration, Chiller Supply Temperature Control, Instability Propagation and Thermal Discomfort, etc.
He also
mentioned the “Dynamic Optimization of Peak Demand Charge” in which employed
Machine Learning – Random Forest in Operation. The morning start-up completed
before 8:45am and the peak demand was reduced.
In the second
part, Mr. Eric Cheung discussed ATAL Multistage Flocculation Magnetic (AMSFM)
R&D Report. AMSFM reduced time consumption
from ~2hr down to ~8min!
Finally, he
introduced ATAL digitalization roadmap to us.
There were several areas stated in the table and he focused on
self-developed IM2S system for E&M system and Self-developed
ACSA system for E&M Maintenance.
He briefed the
existing pain points such as schedule and progress information fragmented and
repetitive manual work, frontline technician repetitive basic job information
hand writing, as well as, lack of one-click summary of maintenance work for
management. The IM2S workflow
was introduced which used Android mobile device to collect worker attendance
record in efficient way.
Lastly, Mr.
Eric Cheung explained how “Chairman Innovation Awards” brought innovation from
bottom-up and it encouraged frontline staff to innovate.
