A Robust Model Evaluation Process for Early-Stage Cooling Load Prediction of Buildings

In the construction industry, a large portion of energy is spent on heating and cooling, which both increases costs and contributes to resource depletion. The aim of the study was to provide and evaluate a robust ML model evaluation process for early design stage cooling load prediction of buildings. For this purpose,...

Multi-Objective Jellyfish Search Algorithm for Two-Level Stochastic Planning and Demand-Side Management of Renewable-Integrated Microgrids

The optimal placement and power injection of photovoltaic (PV), wind, and battery energy storage system (BESS) units are critical for reliable microgrid operation under renewable-generation uncertainty. This study proposes a two-level planning-and-operation framework for a grid-connected microgrid. At the planning stag...

A Secure Multi-Tenant Framework for Institutional Question Answering with Tool-Calling LLMs

Large language model (LLM)-based question-answering (QA) systems are rapidly being deployed in institutional environments, where queries often require both unstructured document retrieval and structured database access. This paper proposes a secure multi-tenant framework for institutional QA that unifies tool-calling L...
