Global asset manager and operator targets Scope 3 emissions in a Green Mark Platinum Building.
As part of its Sustainability Urban Renewal (SUR) strategy, Keppel actively seeks innovative ways to reduce energy use in tenanted buildings. At Keppel Bay Tower, plug load accounted for up to 25% of total building energy use. Reducing plug load by 20% would cut total building consumption by 5%—a significant target. But since the Keppel Bay Tower Building is at full occupancy, any solution has to work seamlessly without disrupting their daily operations.
Keppel began with ENX Energy Monitoring to baseline tenant energy usage. This provided insights into usage patterns and helped validate reduction efforts across the project. It also revealed high standby consumption from several plug-connected devices—many of which remained active during evenings and weekends due to hybrid work patterns.
To address this, Keppel deployed ENX AI Plug Load Controls to centrally manage workspace plug loads. AI algorithms now optimize consumption across tenant spaces, adjusting dynamically without relying on rigid schedules.
Keppel reduced plug load energy consumption by 30%, achieving an overall 5% reduction in total building energy use. This equated to a 12% drop in electrical consumption and energy savings.
With ENX’s AI Plug Load Controls operating autonomously, all stakeholders—including sustainability and project teams—gained real-time insight via remote dashboards, enabling continuous monitoring without user intervention. Keppel is now primed to scale this impact further through the ENX Sustainability Suite, targeting air conditioning, lighting, and broader portfolio-wide optimizations.
Given that plug load can account for up to 25% of total building energy usage, the team focused on reducing energy consumption by targeting plugged-in devices used by tenants.
This not only cuts energy costs for tenants but also helps Keppel, as the building owner, achieve its energy reduction goals. The results were impressive, achieving over 30% reduction in plug load consumption and a minimum 5% reduction in whole-building energy usage.”
