  The ESG Energy Management Challenge ×Aging Infrastructure &amp; High Energy Consumption: 80% of Hong Kong's buildings are over 20 years old, consuming over 60% of Hong Kong's total electricity, making them a primary source of carbon emissions. ×Untraceable Energy Waste: The most critical tool for emission reduction is identifying energy waste sources, but there's a lack of effective monitoring methods. ×Traditional EMS Installation Difficulties: Older power distribution cabinets and MCB boxes have insufficient internal space for traditional CT installation, making the process complex and costly. ×Extremely high Costs: Traditional EMS systems have high hardware/software costs plus high installation expenses, making them unaffordable for most companies.
