Delta Electronics, a Taiwan-based provider of power management, building automation and industrial systems, has deployed an AI-supported digital twin at its Taipei headquarters to model how lighting, sunlight, shading and HVAC systems affect energy use.
The system uses NVIDIA libraries to combine live operating data with physics-based simulations. Delta said the modelling indicated energy-saving potential of up to 20% while optimising occupant comfort.
Delta presented the application at NVIDIA GTC in San Jose. It also demonstrated a separate digital twin used to plan and validate manufacturing processes at its AI server power supply plant in Thailand.
Digital twin models building systems and live data
The digital twin draws on environmental sensors, building controls, lighting systems and HVAC equipment. It models solar heat and natural shading so that different operating scenarios can be tested.
NVIDIA accelerated computing supports AI agents running on edge devices in the building. Delta is using reinforcement learning for HVAC chillers and pumps. Graph neural networks assist with airflow and temperature control in variable air volume systems.
The simulations can compare energy strategies before construction begins. Delta also identified autonomous controls, predictive maintenance and operating cost analysis as possible uses in occupied buildings.
Delta says the system could reduce construction changes and commissioning time.
Taipei headquarters already uses integrated controls
Delta’s Taipei headquarters complex includes Ruey Kuang Building II, a net-zero-certified office completed in 2023. It forms part of the global headquarters complex with Ruey Kuang Building I.
Ruey Kuang Building II operates with 100% renewable energy. Its central control system links HVAC, lighting, security, renewable energy and electric-vehicle charging. An energy management platform monitors electricity use, manages demand and supports fault prediction.
High-insulation, low-emissivity glazing limits external heat while admitting daylight. Operable windows on the northern and southern façades provide natural ventilation.
Delta previously reported that the building’s HVAC and lighting systems achieved savings of 30% and 60%, respectively, against baseline values. These figures were reported before the Omniverse application and are distinct from the digital twin’s energy-saving potential of up to 20%.
The company had established 35 green buildings and two green data centres worldwide by the end of 2024. Delta said these buildings saved more than 45.43 million kWh of electricity during that year and reduced carbon emissions by about 23,330 tonnes.
Thailand factory uses Omniverse for production planning
At its Thailand plant, Delta is using NVIDIA Omniverse in the production of AI server power supplies. Its DIATwin system uses an OpenUSD model containing product designs and data from equipment, robots and manufacturing processes.
DIATwin is used for component assembly simulations, production-line design and process validation. NVIDIA PhysX simulates production processes and is used to refine robot paths before changes are introduced on the factory floor.
Delta also uses NVIDIA Cosmos and the Industrial Anomaly Generator workflow to create synthetic defects for training automated optical inspection models. The company said this had improved inspection accuracy.
DIATwin works with Delta Line Manager and its Human Workstation Solution ACME. Delta said the three systems could shorten production-line deployment and support the replication of manufacturing processes at other locations while retaining central oversight.
