Chan PY - 2015/5/ TI - Thermal Characterization of Smart and Large-Scale Building Envelope System in a Subtropical Climate T2 - International Journal of Energy and Power Engineering SP - 396 EP - 401 VL - 9 SN - 1307-6892 UR - https://publications.waset.org/pdf/10000947 PU - World Academy of Science, Engineering and Technology NX - Open Science Index 100, 2015 N2 - The thermal behavior of a large-scale, phase change material (PCM) enhanced building envelope system was studied in regard to the need for pre-fabricated construction in subtropical regions. The proposed large-scale envelope consists of a reinforced aluminum skin, insulation core, phase change material and reinforced gypsum board. The PCM impact on an energy efficiency of an enveloped room was resolved by validation of the EnergyPlus numerical scheme and optimization of a smart material location in the core. The PCM location was optimized by a minimization method of a cooling energy demand. It has been shown that there is good agreement between the test and simulation results. The optimal location of the PCM layer in Hong Kong summer conditions has been then recomputed for core thicknesses of 40, 60 and 80 mm. A non-dimensional value of the optimal PCM location was obtained to be same for all the studied cases and the considered external and internal conditions. ER -
