Thermal Analysis of the Building Envelope with Infrared Thermography and Simulation in Educational Buildings in the Cold Climate Region

In this study, a thermal analysis of the building envelope of Atatürk University Faculty of Architecture and Design, located in Erzurum in the cold climate zone, was conducted. It is aimed to analyze the thermal efficiency of the educational building on the façade. Firstly, situation analyses were conducted using infrared thermography in the interior spaces and on the exterior. Secondly, a thermal analysis simulation was performed on façade designs used in the faculty. The configurations of indoor and outdoor spaces were obtained with the instantaneous field of view (IFOV) calculator using the Testo 872 thermal camera. Convection thermal loads were applied with the SolidWorks 2022 to simulate the designs. According to the analysis, optimum values were shown in classroom D-306 on glass surfaces, studio D-202 on external walls, studio E-301 on interior walls, studio E-201 on floors, and classroom E-301 on ceilings. According to the surface temperatures on façade sections, the D-202 studio has a 4.1% advantage over the closest performing D-305 and a 33.4% advantage over the farthest performing D-101. According to the simulation results, the glass surfaces used in the autoclaved aerated concrete (AAC) wall had a 39.6% advantage in terms of U-value compared to the glass surfaces in the curtain wall.
