项目摘要

Thermal simulation tools are an essential element in the design of low energy / low carbon buildings. However, they have made little impact on the building design community, despite legislation and industrial and technological development requiring more performance oriented and energy efficient buildings. Although this is a multi-faceted challenge, the research methods used to investigate and address it tend to lack the necessary richness and interdisciplinarity. Current outputs from simulation tools tend to be unrelated to concepts that are meaningful to the building designer and incompatible with his/her constructivist / experimental / 'learning by doing' way of approaching problem-solving. Developers are rarely provided with adequate information about how simulation results can be used to inform design decisions. Consequently, responses to the problem tend to be interpretations of what the simulation community assumes the building designer needs. These responses tend to be based on research methods that are ineffective in matching needs with their appropriate solutions. Research methods such as interviews, structured on-line surveys, reports of specific case studies and observations from working in collaboration with building designers simply describe the problem without showing how it can be solved. Even though much has been achieved in improving input interfaces and facilitating modelling in the early design stages (connecting SketchUp with EnergyPlus via OpenStudio, the set up of AutoDesk Project Vasari, etc.), there is still much to be done about the content and format of building thermal simulation results for them to be effectively used in design decision making. The displays of time-series graphs and tables with temperatures and loads connected to surfaces and volumes are meaningless for building designers to use. Designers need results that effectively connect these temperatures and loads with the building elements they are manipulating. This research proposes to focus on the gap that exists between the output information from simulation tools and what is actually needed for building designers to undertake informed design decisions when designing energy-efficient low carbon buildings - the gap that prevents simulation tools from being better integrated throughout the building design process. Hence, it aims to generate procedures to produce post-processed information and data representation systems that are meaningful to building designers. These procedures and outputs will be illustrated by a series of tested and validated examples developed through interdisciplinary collaboration. As suggested, proper collaboration between building design researchers and building simulation software researchers is essential to acknowledge and brings together the different ways these two disciplines interpret and manipulate building thermal physics. Moreover, the approach creates opportunities for a different research method to be explored. The method consists in inviting the building designer to propose what he/she thinks would be useful building physics information to support his/her design decisions when presented with a design task specifically tailored to facilitate the extraction of this information. Propositions include parameters, indices, diagrammatic and multimodal ways of representing results as well as possibilities of undertaking design changes. This method, not used before in this research area, aims to ensure that simulation tools will be consonant with the way of thinking and modus operandi of the designer, in ways that will mitigate current resistance to incorporating simulation results in design decision making.

热模拟工具是低能 /低碳建筑设计的重要元素。但是，尽管立法以及工业和技术发展需要更多以绩效为导向和节能的建筑物，但他们对建筑设计社区的影响很小。尽管这是一个多方面的挑战，但用于调查和解决它的研究方法往往缺乏必要的丰富性和跨学科性。当前来自仿真工具的输出往往与对建筑设计师有意义的概念无关，并且与他 /她的建构主义 /实验 /实验 /“学习”来解决问题解决问题。开发人员很少提供有关如何使用模拟结果来为设计决策提供的充分信息。因此，对问题的回答往往是模拟社区假设建筑设计师需要的内容的解释。这些响应往往是基于研究方法，这些方法与其适当的解决方案无效。研究方法，例如访谈，结构化的在线调查，有关特定案例研究的报告以及与建筑设计师合作合作的观察结果，只是描述了问题，而无需显示如何解决问题。即使在早期设计阶段改善输入界面和促进建模方面已经实现了很多（通过OpenStudio与EnergyPlus连接Sketchup，Autodesk Project vasari等），但对于它们在设计决策中有效使用的构建热模拟结果的内容和形式仍有很多事情要做。时间序列图和表格的显示器的温度和载荷连接到表面和体积对于建筑设计人员而言毫无意义。设计人员需要有效地将这些温度和负载与正在操纵的建筑元素联系起来的结果。这项研究建议将重点放在模拟工具的输出信息之间存在的差距，以及在设计能节能的低碳建筑物时，建筑设计师实际需要做出明智的设计决策 - 阻止模拟工具在整个构建设计过程中都能更好地集成的差距。因此，它旨在生成生成对建筑设计师有意义的后处理信息和数据表示系统的程序。这些程序和输出将通过通过跨学科协作开发的一系列经过测试和验证的示例来说明。如建议的，建筑设计研究人员与建筑模拟软件研究人员之间的适当合作对于认识并汇集了这两个学科解释和操纵建筑热物理学的不同方式至关重要。此外，该方法为探索不同的研究方法创造了机会。该方法在于邀请建筑设计师提出他/她认为的内容，这将是有用的建筑物物理信息，以支持其设计决策，并提供专门针对促进此信息提取的设计任务。命题包括代表结果的参数，指数，图表和多模式的方式以及进行设计更改的可能性。该方法旨在确保模拟工具与设计师的思维方式和作案操作的方式相吻合，以减轻当前阻力以将模拟结合到设计决策中。
