HONORABLE MENTION | 2021 ASHRAE TECHNOLOGY AWARD CASE STUDIES
In addition, equipment performance deterioration can
be detected. In practice, the detection of performance
deterioration is diffi cult as there is no/limited operating
data that is similar to the declared performance by the
manufacturer for direct performance comparison (e.g.,
actual vs. design performance).
With our AFDD, the highly accurate performance
model for each piece of equipment
can be developed using the PGML
method. The developed model is
considered as the baseline model to
compare future models for performance
deterioration detection.
Investigate Root Causes and Evaluate Severity
Of Detected Faults
The AFDD module is able to perform
cause and effect analysis to
evaluate all possible major factors
involved. AFDD also interprets
equipment's behavior and measures
impacts on equipment operation
and energy performance.
Gives Best-Suited Recommendations
With the AFDD module, the platform
can provide timely actionable
information on practical implementation
for fi xing issues, enabling
proactive decision making and
effective operation (Figure 2). By
leveraging big data analytics, building
owners gain better insight on
building operation and equipment,
facilitating proactive maintenance
and identifying faults immediately.
This ultimately transforms the
maintenance practices from experienced-based
to data-driven decision
making.
Maintenance on Smart Energy Platform
As this innovative solution is a
cloud-based platform, the core algorithm
can be updated via the internet.
There is a back-end team constantly
monitoring the performance

of the platform, including connectivity and data synchronization.
A new version of the platform is released
from time to time. Furthermore, it is easier to frequently
introduce new functionalities thanks to cloud-based
services.
