摘要

为了实现零净运行的碳中和建筑结构,需要逐步改变建筑的设计方式。现代建筑是由多学科设计团队设计的,每个团队都有相互竞争的性能目标。Daisy是一个灵活的基于性能的参数化设计工具,它利用计算设计工作流使设计师主导的多目标优化成为可能,允许建筑设计同时实现跨多个性能目标的高性能。本文以一座63层商业建筑的设计为例,展示了早期设计空间分析如何促进建筑和工程性能指标的更好表现,以及多目标优化的潜力,以实现向碳中和建筑结构的转变。除了建筑结构,为Daisy建立的设计方法可以应用于广泛的土木工程优化问题,使用灵活和可访问的设计空间公式,可以适应项目特定的设计要求。使用Daisy方法生成的设计表明,通过将基准建筑的空间日光自主性提高14.7%,建筑可以从最高能源使用强度设计的10%移动到低于其他模拟设计的97%。然而,这种设计变化显著增加了建筑隐含碳,新设计的建筑隐含碳高于90%的其他建筑模拟。或者,通过将空间日光自主性降低32.8%,该设计的能源使用强度低于其他模拟设计的75%,能源使用强度降低4.4%,建筑隐含碳低于其他模拟设计的60%,从而使建筑隐含碳减少1.3%。

A multi-objective design tool for decarbonising buildings at the concept stage
To enable the move to carbon-neutral building structures with net-zero operation requires a step change in how buildings are designed. Modern buildings are designed by multidisciplinary design teams each of which has competing performance objectives. Daisy is a flexible performance-based parametric design tool which harnesses computational design workflows to enable designer-led multi-objective optimisation, allowing for the design of buildings which simultaneously achieve high performance across multiple performance objectives. A case study of designs for a 63-storey commercial building is presented that demonstrates how early design space analysis facilitates better-performing buildings across architectural and engineering performance metrics and the potential of multi-objective optimisation for enabling the move towards carbon-neutral building structures. Beyond building structures, the design methodology established for Daisy can be applied to a broad range of civil engineering optimisation problems using a flexible and accessible design space formulation that can be adapted for project-specific design requirements. Designs generated using the Daisy methodology demonstrated that by increasing the spatial daylight autonomy of the benchmark building by 14.7%, the building can be moved from the 10% of designs with the highest energy use intensity to lower than 97% of other simulated designs. However, this design change significantly increases the building embodied carbon, with the new design having a building embodied carbon which is higher than 90% of other buildings simulated. Alternatively, by reducing the spatial daylight autonomy by 32.8%, the design can have an energy use intensity which is lower than 75% of other simulated designs, with a 4.4% reduction in energy use intensity, and a building embodied carbon which is lower than 60% of other simulated designs, enabling a 1.3% reduction in building embodied carbon.
