  • Phase change materials in building science applications
  • Free-cooling heat exchanger design

Research Summary

Heating and cooling loads account for approximately 40% of the energy consumption in residential buildings. Research has shown that the incorporation of phase change material (PCM) into a building envelope system can significantly reduce energy consumption. Stephen is developing a numerical model for heat transfer through multi-layered building envelope systems incorporating PCM composites. This modeling tool will be used to study potential benefits from this passive solar technology. PCM thermal properties are characterized using differential scanning calorimetry and the evolution of latent heat throughout the phase change process is incorporated into the model through a source term formulation of the heat equation. Response surface methodology is used to optimize the PCM composite performance under the local Kentucky climate.
