Whereas the modern architecture trends to an extensive use of glazing elements, buildings are increasingly required to minimize the external energy demand, cutting down the energy needed and covering the residual demand using local energy generation solutions. In this context, the integration of optimized Semi-Transparent Photovoltaic (STPV) elements seems to present a promising energy saving potential, leading to significant reductions of the heating, cooling and lighting loads while the on-site electricity generation is supplied. In mild climate areas, building glazings are required to perform as solar control systems with a low solar factor in order to avoid overheating. However, g-value is frequently unavailable in the data sheet of the STPV elements, making it difficult to design the optimal building solution. In the present work, an indoor testing facility to analyze the solar factor of STPV elements has been further developed and validated. The operating principles of the calorimetric system as well as the experimental data obtained in the validation stage are presented. Results show that the system accuracy and sensitivity are fully adequate to perform detailed analyses of the solar factor of STPV glazings. Furthermore, g-value variations with the transparency degree have been analyzed over different electrical operating points.
