项目摘要
Decarbonizing the built environment presents many significant challenges. One is developing long-lived, fast-growing, bio-based construction materials at scale without destroyingDecarbonizing the built environment presents many significant challenges. One is developing long-lived, fast-growing, bio-based construction materials at scale without destroying soils, forests, and grasslands. Another is fully harnessing ambient heat sources and sinks for low-grade heating and cooling without excessive ductwork, piping, and refrigerants. This research program's long-term vision is to simultaneously address these two challenges by developing regional solutions for functionally integrated, bio-based buildings. Not only will these new bio-structures store carbon by prolonging the storage phase of natural carbon cycles, but they will also harness ambient energy for thermoregulation and ventilation with little to no equipment. Making these groundbreaking advances in integrated design requires concordant innovations at the material and building scale. Therefore, we focus on upgrading bio-based materials with special thermal functions by optimizing their internal composition, geometry, and surface morphology. We also focus on understanding the fluid mechanics of temperature cascades, where adjacent rooms exchange heat, so it is recycled upstream or recovered downstream of the warmest room. This new class of thermally-driven ventilation could eventually work in synchrony with the heat-exchanging materials developed in parallel investigations. This research program will focus on three short-term objectives planned over the next five years, working with a combination of theory, simulations, and experiments. Objective A investigates the use of load-bearing, bio-based composites for dynamic insulation. The focus is on characterizing the primary and supplementary heat-exchange mechanisms experimentally and optimizing for them. Objective B investigates the use of load-bearing, bio-based composites for thermal mass coupled with buoyancy ventilation. The focus is on understanding surface heat transfer and stratification profiles in situ and optimizing surface morphology accordingly. Finally, objective C investigates buoyancy flows in a temperature cascade. The focus is on exploring spatial arrangements that can sustain a thermally-driven ventilation flow, generate a temperature cascade between rooms, and recycle or recover heat across partition walls. We will use dynamically-scaled physical models and simulations to investigate these novel configurations. This program will help decarbonize construction industries in Canada and globally, while also creating new value-added supply chains in the bio-economy. It will train powerful industry-facing & public-oriented agents of change in the transition to a lower-carbon, more just, future for Canada.
建筑环境的脱碳带来了许多重大挑战。一个是大规模开发寿命长、增长快的生物基建筑材料,而不破坏建筑环境。一个是大规模开发寿命长、生长快的生物基建筑材料,而不破坏土壤、森林和草原。另一个是充分利用环境热源和散热器进行低级加热和冷却,而无需过多的管道系统,管道和制冷剂。该研究计划的长期愿景是通过为功能集成的生物建筑开发区域解决方案来同时解决这两个挑战。这些新的生物结构不仅可以通过延长自然碳循环的储存阶段来储存碳,而且还可以利用环境能量进行温度调节和通风,而几乎不需要设备。 在集成设计方面取得这些突破性进展需要在材料和建筑规模上进行协调创新。因此,我们专注于通过优化其内部组成,几何形状和表面形态来升级具有特殊热功能的生物基材料。我们还专注于了解温度级联的流体力学,相邻的房间交换热量,因此它在最温暖的房间上游回收或下游回收。这种新型的热驱动通风最终可以与平行研究中开发的热交换材料同步工作。 该研究计划将侧重于未来五年计划的三个短期目标,结合理论,模拟和实验。目的研究承重生物基复合材料在动态绝热中的应用。重点是表征的主要和补充的热交换机制实验和优化。目的B研究承重生物基复合材料在热质与浮力通风耦合中的应用。重点是了解表面传热和分层配置文件在原位和优化表面形态。最后,目标C研究温度级联中的浮力流。重点是探索空间安排,可以维持热驱动的通风流,在房间之间产生温度级联,并通过隔墙回收或回收热量。我们将使用动态缩放的物理模型和模拟来研究这些新的配置。 该计划将有助于加拿大和全球建筑业的脱碳,同时也在生物经济中创造新的增值供应链。它将培训强大的面向行业和面向公众的变革代理人,以实现加拿大向低碳,更公正的未来过渡。
