Description
The development of various advanced materials and their subsequent integration into innovative building envelope concepts has the potential to achieve energy savings. Additionally, their usability in practical applications can be enhanced via the use of building energy simulation (BES) methods. Experimental procedures in conjunction with numerical computations could enable the prediction of the future performance of solar thermal façade concepts. The presented study is focused on the thermal response of a transparent insulation material (TIM) incorporated in a façade structure. An experimental prototype of a solar façade element with both a selective and a nonselective absorber was developed for use as part of an opaque building envelope. Experimental measurements were conducted using dynamic outdoor methods with the aim of verifying a BES model. Combined with the measured thermal and optical properties of key materials implemented, an integrated model was developed to simulate the effect on the thermal performance of the TIM-based façade prototype in the EnergyPlus computational engine. This was primarily focused on the capability of the thermo-optical properties of the proposed prototype to respond in an adequate way under transient boundary conditions. In the first part of this study, a specific characterization for the appropriate modelling and simulation of the given solar based prototype is presented. In the second part, the capability of one widely used BES tool is analysed in terms of its ability to model the energy and thermal performance of the presented façade model. The good consistency between the simulation results and the experimental data indicates that the simulation model was reliable when predicting the thermal performance of TIM based façade prototypes, though with some specific limitations. The methodology developed in this study is expected to provide a reference for simulating the thermal and energy performance of TIM-based building elements with two different solar absorbers.
