DEMO: Web-CozyBench - A Web-Based Platform to Benchmark Thermal Comfort Provision using Digital Twins

Abstract

Providing individual thermal comfort to occupants while minimizing energy use is a significant challenge in smart building management. Simulation-based benchmarks such as Co-zyBench have been developed to evaluate occupant-centric thermal comfort provision systems using Digital Twin (DT) models of buildings and occupants. In this paper, we present Web-CozyBench, a web-based platform that extends Co-zyBench by offering an intuitive, user-friendly interface for configuring experiments, running co-simulations, and visualizing results. Web-CozyBench lowers the barrier to entry for researchers and practitioners to benchmark thermal comfort provision systems by eliminating the need to directly handle complex simulation configurations. We outline the system design of Web-CozyBench and demonstrate its usage through a step-by-step scenario. The demonstration showcases how users can easily set up building and occupant digital twins, select a control strategy, run the simulation, and analyze performance metrics such as comfort and energy efficiency through the web interface.
