Evaluating the impact of façade wall assemblies on outdoor thermal comfort using a solar simulator
Rapid urbanization has intensified the Urban Heat Island (UHI) effect in many cities worldwide, leading to higher ambient temperatures and reduced thermal comfort. Building surfaces play a pivotal role in this process, as their materials and configurations affect how heat is absorbed and re-emitted into the surrounding environment. To better understand and mitigate these effects, this master’s thesis will investigate the thermal behavior of selected façade wall assemblies under controlled “sunlight” conditions using the Solar Simulator at the Zero Carbon Building Systems (ZCBS) Lab.
Keywords: Outdoor thermal comfort, experimental setup, solar simulator.
In this thesis, up to three façade wall assemblies will be designed in collaboration with A/S researchers and tested under the controlled conditions of the Zero Carbon Building Systems Lab’s Solar Simulator. A sensor array—including, for instance, globe thermometers, infrared cameras, and thermocouples—will measure parameters such as surface temperature, mean radiant temperature, and ambient air temperature. Multiple measurement campaigns will capture data at standardized irradiance levels. The resulting data sets will be statistically analyzed (e.g., using Python, R, or MATLAB) and compared with existing literature.

The primary goal of this thesis is to evaluate the performance of up to three different wall constructions in terms of their contribution to outdoor thermal comfort. Data will be generated through experimental measurements using the Solar Simulator in the ZCBS Lab:
• Explore up to three façade wall assemblies for testing under the Solar Simulator in collaboration with A/S researchers and technicians.
• Plan and integrate a comprehensive sensor array (e.g., globe thermometers, infrared cameras) to capture key thermal parameters.
• Conduct a series of controlled tests to assess each assembly’s performance under standardized irradiance levels.
• Statistically analyze the collected data and benchmark findings against existing literature.
