Abstract

Abstract The paper provides an architectural analysis of the switchable PV-EC glazing technology based on combining photovoltaic (PV) technology with electrochromic (EC) glazing. The integration of these technologies is considered to constitute future-oriented façade solutions in shaping buildings that are energy-saving and environmentally friendly. The paper aims to define theoretical models of windows using PV-EC technology as solutions adequate from the architectural point of view. To achieve this goal, a comparative analysis of three PV-EC technologies was conducted, i.e., side-by-side (SBS) technology and tandem technologies, namely tandem solid technology (TST) and tandem liquid technology (TLT). The analysis covered functional aspects related to such issues as thermal and visual comfort, energy and aesthetics. The analysis led to extracting the features of the three compared technologies; consequently, their strengths and weaknesses were determined. As a result, seven window models were developed which, based on the above analysis and the insights derived from it, were recognized as the solutions in which the potential of PV and EC technology is best used. The dominant advantages of SBS, being the most developed technology and one with the greatest flexibility in construction applications, are indicated. The research is of a contributory nature, as it constitutes the basis for further numerical and simulation research. Such studies may prove useful to architects in making design decisions, especially at the initial design stages. However, at the current stage of technological development, the study mainly serves as an introduction to further research on improving the PV-EC properties towards integration with the building and its architecture.
基于PV-EC技术体系结构分析的PV-EC窗口理论模型
摘要:本文对基于光伏(PV)技术与电致变色(EC)玻璃相结合的可切换PV-EC玻璃技术进行了体系结构分析。这些技术的整合被认为构成了面向未来的立面解决方案,以塑造节能和环保的建筑。本文旨在定义使用PV-EC技术的窗户的理论模型,从建筑的角度来看,这是适当的解决方案。为了实现这一目标,对三种PV-EC技术进行了比较分析,即并排(SBS)技术和串联技术,即串联固体技术(TST)和串联液体技术(TLT)。分析涵盖了与热和视觉舒适、能源和美学等问题有关的功能方面。通过分析,提取了三种比较技术的特征;因此,确定了它们的长处和短处。因此,基于上述分析和由此得出的见解,开发了七个窗口模型,这些模型被认为是PV和EC技术潜力得到最佳利用的解决方案。指出了SBS的优势,它是最发达的技术,在建筑应用中具有最大的灵活性。这项研究具有贡献性质,因为它为进一步的数值和模拟研究奠定了基础。这样的研究对建筑师的设计决策是有用的,尤其是在最初的设计阶段。然而,在目前的技术发展阶段,这项研究主要是为了进一步研究如何提高PV-EC的性能,使其与建筑物及其建筑融为一体。
