Advanced Building Envelope Systems for Improved Energy Performance of Multistory Buildings

多层建筑可以容纳增加的密度，但是，它们捕获太阳辐射用于发电和发热的能力受到限制。这是由于相对于可用于主动收集太阳能的总面积，屋顶和立面面积减少。这些缺点进一步受到现有太阳能技术的限制，这些技术只提供有限形状和尺寸的太阳能电池板，因此阻碍了它们在先进建筑设计中的应用。在多层建筑中，屋顶集成太阳能技术的潜力趋势随着建筑物的高度而下降，而立面潜力的趋势由于表面积的增加而增加。集成在南立面的光伏电池板通常比南向屋顶表面（具有最佳倾斜角度）的光伏电池板每单位面积产生的电力少约40%。然而，与平面相比，操纵立面几何形状可以增加这些立面的发电潜力。因此，需要开发建筑围护结构设计/幕墙的策略，以增加其太阳能潜力。这应该伴随着模块化光伏和混合光伏/热板的开发，用于非传统建筑物的外壳。该研究计划的长期目标是为混合用途太阳能社区的设计制定指导方针，将能源效率与有效的太阳能技术相结合。短期目标旨在通过建筑围护结构/幕墙系统的先进设计和建模，结合优化的几何形状、幕墙技术和太阳能收集器，提高多层建筑的能源性能。* 本研究中使用的方法是在幕墙系统的各种几何设计中开发结合不同层/膜和太阳能技术的建筑围护结构方案。然后将进行综合能源模拟，以分析这些配置对选定公寓和办公室单元的供暖、制冷和采光的影响。最佳包络配置的性能将在一些邻域模式下进行分析。这项工作可能会扩展到实验阶段，这可能会导致 * 与 * 行业合作伙伴合作生产示范项目的原型。* 这项研究预计将对学术、研究和工业部门产生重大影响。它将填补知识和理解中高层建筑的能源性能以及建筑围护结构设计对其能源产生潜力的影响方面的空白。研究结果将为创新建筑围护结构设计和BIPV/T技术和产品的开发提供动力和机会。该研究计划将涉及3名硕士生和2名博士生。* **

Multistory buildings can accommodate increased density, however, their capacity for capturing solar radiation for electricity and heat generation is restricted. This is due to the reduced roof and facade areas relative to the total floor area that is available for active collection of solar energy. These drawbacks are further constrained by existing solar technologies, which offer only limited shapes and dimensions of solar panels, hindering therefore their application in advanced architectural design.***In multistory buildings, the trend of the potential of roofs to integrate solar technologies decreases with the height of the building, while the trend of facades potential increases, due to increased surface area. PV panels integrated in south facades usually generate about 40% less electricity per unit area than those in south-facing roof surfaces (with optimal tilt angle). However, manipulating facade geometry can increase the energy generation potential of these facades as compared to flat surfaces.There is a need therefore to develop strategies for building envelope design/curtain wall to increase their solar potential. This should be accompanied by development of modular PV and hybrid PV/thermal panels, for applications in non-conventional building envelopes.***The long-term objective of this research program is to develop  guidelines for the design of mixed-use solar communities, combining energy efficiency with effective solar technologies. The short-term objective aims at enhancing the energy performance of multistory buildings through advanced design and modelling of the building envelope/curtain wall systems, combining optimized geometries, curtain wall technologies and solar energy collectors. ***The approach to be used in this research is to develop scenarios of building envelope combining different layers/films and solar technologies within various geometrical designs of curtain wall systems. Integrated energy simulations will be then conducted to analyze the effect of these configurations on heating, cooling and daylighting of selected apartment and office units. Performance of optimal envelope configurations will be analyzed in some neighborhood patterns.The work may be extended into experimental phase, which can result in*producing prototypes for demonstration projects in collaboration with*industry partners. ***This research is expected to have a significant impact across the academic, research and industrial sectors. It will move to fill gaps in the knowledge and understanding of the energy performance of mid and high-rise buildings and the effect of building envelope designs on their energy generating potential. Results of the research will open motivation and opportunities for the development of innovative building envelope designs, and BIPV/T technologies and products.This research program will involve up to 3 Master students and 2 PhD candidates.****** **
