ABSTRACT
Façade systems play a critical role in the thermal performance as well as energy use in buildings. This study investigates BIM-integrated kinetic façade systems for hot climates through a comprehensive case study of Lusail Plaza Tower, Qatar. Using Autodesk Revit, Dynamo visual programming, Insight 360, and Green Building Studio, three façade configurations were modeled and analyzed: conventional baseline (without shading), enhanced (with static shading), and kinetic (with adaptive shading) systems. The kinetic façade-based building model performed remarkably close to the ASHRAE defined target for energy use intensity (EUI) with a value of 203 Kwh/m²/yr. The use of kinetic façade for photovoltaic-based energy generation is also assessed indicating the potential of 6.8 million kWh/year with a payback period of about 22 years. The study helps validate the usefulness of BIM-based methodology for early-stage sustainable façade design decisions particularly for hot climates, contributing to the quantitative evidence for environmentally responsive façade design.
