Abstract

This study develops a transient thermal model for an indoor in which a photobioreactor (PBR) is integrated into one of its facades. Thermal comfort, energy consumption, and carbon dioxide (CO2) emissions were interpreted in different design scenarios for Izmir, Turkey. As a result, it was determined that a 20% window-to-wall ratio (WWR) provides the most comfortable results, and the algae usage increases the annual comfort by 19% and reduces the heating/cooling demand. Compared to a water wall, it provides a 17% reduction in energy consumption and CO2 emissions.
