Green Retrofitting and Sustainability

Reviewed by : King Wan Eco Solutions Pte Ltd.


The COVID-19 crisis has induced reduction in revenue and increase in operating expenses to most sectors due to “new normal” compliance requirements, like Social Distancing (reduced seat capacity), Travel Restrictions (higher labour costs), and personnel identity and temperature monitoring (additional labour), etc.
Adoption to AI-enabled services like Asset Performance Management and Digital Utilities Monitoring can help reduce operating costs and conserve cashflow where possible. Moreover, such digital platform allows for consolidation and centralisation of data, and with application of advanced analytics, insights can be provided on building behaviour, and how improvements can be made to reduce wastage of resources.


Asset Performance Management (APM)

The APM platform is enabled with Artificial Intelligence (AI), and is able to assist the facilities management team for dayto-day operations of the Chilled Water Plant.
Leveraging on existing available data from BMS/EMS (or IoT sensors in cases where BMS data is not available), an AIenabled platform could better work with buildings in-house engineers remotely to optimise energy consumption, resolve alerts and issues, while simultaneously recommending maintenance activity with performance tracking on an ad-hoc basis. There are 4 key features to such APM system:

Anomaly Detection Module

Automatically detect abnormal behavior in system vs the normal pattern. Reduce unnecessary wastage in energy consumption. React to anomalies before operations gets disrupted.

Failure Detection Module

Automatically detect deviations in performance and diagnose which component of the system is malfunctioning. Able to detect component degradation before system failure. As a result, the modules reduces operational downtime and increase system performance.

False Alarm Detection Module

Identification of “sparks” or false alarms and its eventual suppression. Reduces cluttering of minor warnings within the user interface, and increase effectiveness of reacting towards such “sparks”.

Condition Based Asset Life Cycle Management

Ability to diagnose and give indications on equipment health, and provide early warnings of component degradation, in order to prompt operator to upkeep maintain the asset/equipment in tip top condition for best performance.

Digital Utilities Monitoring and Data Analytics

Using wireless sensors to capture consumption of electricity and water, data is sent to the cloud and allows for easy access anytime, anywhere. Consolidation and tabulation of data can also be done easily via access using a web browser, and customized reports can be generated according to user’s needs.
Adoption to Digital Utilities Monitoring helps to reduce laborious tasks like manually recording readings from a conventional power meters and water meters, especially in buildings where such meters are in large quantities. Digital Utilities Monitoring also reduces the chances of human errors in recording of readings.
Installation of such a system is simple, with minimum to no disruption to daily operations.

Application of data analytics to such digital utilities monitoring system, allows for detection of anomalies in power and water consumption, which brings to light any faulty equipment, user abuse in facilities, leakage, or other situations that is “out of the norm” during day-to-day operations.

Meeting Sustainability Goals

Moving towards digitalisation is a first step towards our global and national sustainability goals to reduce our carbon footprint. With digitalisation, detailed data can be collected on resource consumption of a building, forming a baseline of a building’s operations behaviour and the equivalent carbon emissions. With centralization and consolidation of data, as well as application of advanced analytics, improvements can be implemented to reduce wastage of resources, such as energy and water.


Improvements can be in the form of optimising operating conditions, or Green Retrofitting to replace existing equipment with more efficient that is of the latest technology (for example, switching from T8 fluorescent lamps to LED lamps). Harnessing renewable energy (such as using solar energy) can also be considered to reduce consumption of conventional fossil energy, and in turn reducing carbon footprint.

Even after improvements has been implemented, the digital platform enabled with artificial intelligence can continuously monitor building behaviour and continuously improve on daily operations strategy, maintaining the optimal operating conditions and make sure resource wastage is kept at the lowest level.

Green Retrofitting

After the digitalisation process, data can be collected and analysed to discover areas or systems that can be improved in the building to reduce energy consumption through Green Retrofitting. Some examples of building assets and equipment that can be retrofitted or upgraded are:

  • Heating, Ventilation, and Air-conditioning System (HVAC)

  • Lighting system

  • Indoor Air Quality (IAQ) sensors

  • Installation of solar panels to harness renewable energy


After implementation of Green Retrofitting, the digital platform equipped with AI data analytics will be able to continuously optimise energy consumption through learning the patterns in daily operations and adjusting system operating parameters according to dynamic and live conditions.
Green financing programs are available that simplifies the sustainability process by combining the technical assessment, installation, and maintenance, together with financing options. Companies can tap into the green financing program and leverage on green loans, grants or shared savings model to achieve energy efficiency improvement and cost-savings for buildings without incurring heavy initial capital outlay. Such programs makes it simple and seamless for businesses to adopt energy efficiency and reap the financial and environmental benefits.
