The rigid building structures (e.g., walls, floors, columns, roofs, etc.) can be used as active sensible/latent energy storages systems (commonly known as Active Wall Structure). Energy can be stored in such structures from renewable sources (e.g., solar thermal, waste heat, etc.) and can be utilized when required. The proposed activity (duration: 6 months) will investigate the effect of integration of phase change material (PCM) within the structural components of building where such integration will improve overall energy efficiency of the building. In the present study, analytical modeling will be carried out for a porous medium with PCM to understand how the PCM interacts with porous medium properties, i.e., material, porosity, and permeability. A Computational Fluid Dynamics (CFD) modeling of structural components with PCM will be simulated to obtain a right combination of porous medium porosity and PCM for optimization of melting/freezing rate. A small scale prototype structure will be developed. PCM will be integrated on the structural component. The PCM with porous medium inside structural component will enhance melting/freezing and could achieve important energy savings in buildings. Experimental testing will be carried out and compared with analytical/simulation results. These gradual research and analyses processes and prototype development and verification will lead to commercialization of this technology in building systems. Newton Group will partner with University of Guelph in the proposed study and use the results in investigating the business case for developing the optimized energy efficient buildings. Newton Group has been using technologies, such as, active wall energy storage system, integrated pond for temperature cooling, and passive heating/cooling to their design-build projects. Project like this will assist stimulation of green investment, green innovation, and will create more employment opportunities for local people and environment friendly technologies. In the long run, such system has the potential for cost and carbon footprint reductions in Ontario as well as in Canada.

刚性建筑结构（例如墙壁，地板，柱子，屋顶等）可以用作主动/潜在能量储藏系统（通常称为活动墙结构）。能量可以存储在可再生能源（例如太阳热，废热等）中，并且可以在需要时使用。提出的活动（持续时间：6个月）将研究建筑物结构组件内相变材料（PCM）的影响，在该结构组件中，这种整合将提高建筑物的整体能源效率。在本研究中，将为具有PCM的多孔培养基进行分析建模，以了解PCM如何与多孔培养基特性（即材料，孔隙率和渗透率）相互作用。将模拟具有PCM结构组件的计算流体动力学（CFD）建模，以获得多孔媒体孔隙率和PCM的正确组合，以优化熔化/冷冻速率。将开发小规模的原型结构。 PCM将集成在结构组件上。具有多孔介质内部结构组件的PCM将增强熔化/冷冻，并可以在建筑物中节省重要的能源。实验测试将与分析/模拟结果进行比较。这些逐步的研究和分析过程以及原型开发以及验证将导致该技术在建筑系统中的商业化。牛顿集团（Newton Group）将与圭尔夫大学（University of Guelph 开发优化的节能建筑物。牛顿集团一直在使用技术，例如主动壁存储系统，用于温度冷却的集成池，以及在其设计构建项目中被动加热/冷却。这样的项目将有助于刺激绿色投资，绿色创新，并将为当地人和环境友好的技术创造更多的就业机会。从长远来看，这种系统有可能减少安大略省以及加拿大的成本和碳足迹。
