Evaluation of post processing analysis to determine optimal thermo-optical properties for adaptive glazing systems with quick adaptation speed

Abstract

Adaptive envelope technologies are considered as ones of the most promising for reducing the energy use in buildings. Nonetheless, their real-world implementation is low, because of fragmented researches and limited capabilities of current BPS (building performance simulation) tools in evaluating properly their behaviour at a time-scale consistent with the highly dynamic drivers effecting the adaptation mechanism. The aim of this research is to investigate the effectiveness of simplified methods to determine optimal thermo-optical properties for adaptive glazing systems able to modulate two parameters, g-value (or SGHC) and tVk, with quick adaptation speed (5 minutes), using inverse approach and post processing analysis. This type of study is meant to provide a useful tool in early design phase for choosing the best fitted adaptive technology and for the development of new adaptive glazing technologies, since it identifies the requirements to be satisfied by means of the best suited technological solutions.
