Abstract

A calibrated building energy simulation model assessed a dynamic façade system (including shading and natural ventilation) in an office, achieving a mean absolute error of 2.1% for heating and cooling. Several operational strategies were evaluated, optimizing shading via solar irradiance setpoint. Integrating natural ventilation yielded a 14.9% energy reduction compared to a no-ventilation scenario. Sensitivity analysis showed minimal total energy changes with different occupancy densities and natural ventilation rates, yet occupancy density strongly affected the heating-to-cooling ratio. Broadening heating and cooling setpoints further reduced energy use, highlighting the system’s significant potential for efficient office design.
