FluxTwin-Core: An Open-Source Web-Based Platform for Scalable Data Center Thermal Management

28 July 2026
While cooling efficiency of data centers is traditionally evaluated using computational fluid dynamics (CFD) simulations, thermal results are often delivered as static reports and isolated engineering files, which significantly limits their accessibility for operators, facility teams, and decision makers. In this study, we […]

A self-assessment framework for evaluating efficiency of data centers

26 February 2026
Increasing global data center energy consumption, with the rapid digitalization of society, has driven the need for comprehensive assessment reports periodically. Current challenges include the complexity of collecting data and calculating Key Performance Indicators (KPI) within the corresponding reporting period. To address this, we introduce the Self-Assessment Tool (SAT) as a unified, modular, and extensible framework for the evaluation of thermal […]
