Suntec City Office Towers: Digital Twin & Smart ACMV

Suntec City Office Towers required an ACMV upgrade that went beyond mechanical plant replacement: the project scope included integrating smart controls, predictive analytics, and a Digital Twin framework into a live Grade-A commercial building with diverse existing BMS infrastructure. The design had to optimise occupant comfort and energy performance across multiple tenanted floors without disrupting building operations.

Led digital and IoT systems design, working alongside Meinhardt's MEP team. Specified occupant-centric dynamic airflow balancing with remote zone monitoring. Designed predictive ML algorithms for temperature capacity optimisation, redirecting conditioned air to spaces requiring it most. Integrated indoor CO₂ monitoring for demand-controlled ventilation. Implemented climate compensation control using real-time weather data. Designed the Digital Twin framework integrating IT and OT systems into a unified operational and enterprise data model. Delivered BMS integration across AHU, VAV boxes, and Energy Valves through an open protocol platform with a centralised live operations dashboard.

First digital twin integration for Suntec City delivered on schedule. Predictive ML optimisation enabled targeted airflow management reducing energy consumption across tenanted floors. Real-time operational visibility established across all building systems. Retrofit delivered without operational disruption to tenants, proof that IT/OT convergence in Singapore doesn't require a new building, only a shared data layer over the one already standing.

The same diagnostic logic from deployments like this one, applied to your business in half a day.
