We need to characterize the optical properties of these complex fenestration systems through measuring their spectral, bidirectional distribution function to evaluate their performance for energy efficiency, daylight availability, and building sustainability purposes. This paper represents the characterization of two different Prismatic Material (PM) products that apply to diverse purposes in buildings. First, we conduct two methods to measure the Bidirectional Scattering Distribution Function (BSDF) of materials; genBSDF raytracing tool of Radiance and goniophotometer measurement (goniophotometry). In the next step, we compare the genBSDF result with the results of the goniophotometry. The aim of this study is to evaluate the angular-based optical behavior of prismatic materials in distributing light and also to assess the reliability of the genBSDF tool result for further simulation of high-performance building purposes. The results demonstrate that the genBSDF raytracing tool method creates a comparable result to the goniophotometry method. Therefore, genBSDF is a robust tool for assessing the solar-optical properties of PMs.}, journal={BUILDING AND ENVIRONMENT}, author={Haghani, Masoome and Jonsson, Jacob C. and Salamati, Mohammad and Place, Wayne}, year={2023}, month={Jun} }

Apart from the significant role of TC windows in thermal energy conservation in buildings, they affect the indoor daylight performance due to their lower visible transmittance rate and tinted appearance. In this paper, we carried out a comprehensive study on the impact of [email protected] thermochromic glazing, fabricated by the authors, on indoor daylighting performance of a typical office room. The spectrophotometry test on the fabricated TC glass shows a significant modulation ability in near-infrared wavelengths. Based on the measured optical transmittance, daylight behaviors of the glazing were elaborated in terms of visual comfort, color quality of the transmitted light, non-visual daylight availability, and artificial lighting load, using computer simulation methods and numerical calculations. Finally, the paper offers an interactive approach between material development and fabrication methods on one hand, and holistic thermal and daylight analysis of the product on the other hand. This approach optimizes the physical properties of a TC glazing in tradeoff between solar modulation ability, visible transmittance, and color appearance.}, journal={BUILDING AND ENVIRONMENT}, author={Salamati, Mohammad and Mathur, Pegah and Kamyabjou, Ghazal and Taghizade, Katayoun}, year={2020}, month={Dec} }

Among different buildings components, windows are considered as one of the most inefficient parts; so studies on energy-efficient windows have recently become crucial due to the energy crisis in the world. Thermochromic (TC) glazing is a new generation of energy-efficient smart glazing that passively changes its transmittance rate in response to temperature. Vanadium dioxide (VO2) is the most widely used TC material in thermochromic windows. To increase the transparency of glazing, augment the thermochromic properties of VO2, and set the transition temperature near the comfort zone, many dopants have been investigated and many fabrication methods have been proposed. In this research, by using the sol–gel method, we doped tungsten ions (W6+) on a vanadium dioxide film. Titanium dioxide (TiO2) was also added to the solution to produce a nanoparticle structure with both thermochromic and photocatalytic properties. To quantify the energy saving achieved by the produced TC glazing compared to standard products, a simple model of a room in a residential building was created with EnergyPlus computer software. The simulation results showed that the fabricated TC glazing could bring about a significant reduction in energy demand of buildings compared to current approaches.}, journal={CONSTRUCTION AND BUILDING MATERIALS}, author={Salamati, Mohammad and Kamyabjou, Ghazal and Mohamadi, Mohadese and Taghizade, Katayoun and Kowsari, Elaheh}, year={2019}, month={Sep}, pages={477–482} }
