“Thermoelectric Facades: Modelling Procedure and Comparative Analysis of Energy Performance in Various Climate Conditions” presents a methodology for simulating energy performance of thermoelectric (TE) facade systems. These novel facade systems can be used for localized heating and cooling in buildings. Simulations were performed to investigate impacts of TEs on buildings’ energy performance by comparing them against a conventional HVAC system. The study was carried out by modeling a typical office space in IDA ICE software program, with an area of 3x3 m (10x10 ft) and included one exterior wall (with an incorporated window), three adiabatic interior walls, a floor, and a ceiling. Simulations were performed for 15 different climates (climate zones 1A to 8). To simulate TE system’s energy performance, an electric radiator, with characteristics that most closely matched that of the TE system, was used. This included assigning a certain area to the radiator and calculating its rated input power based on the climate condition. Based on the previously conducted research, 15% wall coverage was determined as the optimum area for heating and cooling production. Therefore, area of the electric radiator was assigned as 1.35 sq.m. (15 sq.ft.). Given that the TE system’s performance and output depend on the temperature difference between the building’s internal and external environments, this was separately calculated for each climate zone and used for modeling energy performance of the TE system. Energy modeling results showed a reduction in energy consumption and improved performance of TE facade systems, compared to conventional HVAC systems. Energy Usage Intensity (EUI) comparison showed that the TE system exhibited improved performance in all climate zones. The results concluded that TE materials are promising intelligent components that can be used in facade assemblies for heating and cooling purposes.
