绿色建筑以节约资源、保护环境、自然和谐共生为根本目标,其方案设计阶段在考虑建筑本身适用、美观、经济等特性的同时,更需要考虑基于环境和资源的建筑综合性能评价和优化,从而做出科学的决策。在分析绿色建筑方案设计与综合性能评价的关系及方案设计存在的问题,建筑性能模拟的基础上,归纳提取绿色建筑方案设计的影响因素和性能评价指标,建立绿色建筑方案设计优化决策模型,并运用Excel工具对模型求解,通过实例验证其有效性和适用性。 相似文献

方案设计阶段的设计决策对建筑性能有重要影响,窗口设计是方案设计阶段重要的一部分,大量的研究表明,合理布置建筑窗口有利于控制建筑的能耗。本文通过建立理想化的模拟小室,利用DesignBuilder分析西安地区办公空间的不同窗墙面积比和窗口朝向对建筑负荷的影响。研究对象的窗墙面积比范围在0~0.9,窗口朝向是以30°为步幅,设置了12个窗口朝向,在不同窗墙面积比和窗口朝向的组合变化下,全年累计总负荷与无窗时相比增加了5.48%~157.33%。通过对模拟结果的拟合分析,提出建筑总负荷与窗墙面积比、窗口朝向之间的数学关系式,简化建筑冷热负荷模拟计算方式,为办公建筑立面设计提供快速的设计模拟理论依据。 相似文献

The subject of this paper is the design analysis process of an experimental solar house, driven by the overarching goal to
obtain net-zero energy performance while being functionally optimal and architecturally ambitious. The house was commissioned
to participate in an international solar home competition called the Solar Decathlon. The paper demonstrates the use of simulation
to support design decisions at various stages of the design process. Through it, the paper highlights attributes of simulation
tools that are needed for supporting the design process effectively. In addition, this paper shows a novel use of building
simulation by extending it to also inform the final use and operation of the house during the competition period. Finally,
the paper also contributes to the design of solar homes by showing how their performance assessment and evaluation criteria
can be different from homes that are served by the grid. 相似文献

This paper presents a framework for integrating building information modelling (BIM) and object-oriented physical modelling-based building energy modelling (BEM) focusing on thermal simulation to support decision-making in the design process. The framework is made of a system interface between BIM and Modelica-based BEM and the visualization of simulation results for building designers. The interface consists of the following two major features: (1) pre-processing BIM models to add required thermal parameters into BIM and generate the building topology and (2) translating BIM to Modelica-based building energy modelling automatically and running the thermal simulation. The visualization component presents the simulation results in BIM for designers to understand the relationship between design decisions and the building performance. For the framework implementation, we have created a ModelicaBIM library and utilized the Modelica Buildings library developed by the Lawrence Berkeley National Laboratory. We conducted a case study to demonstrate and validate the framework simulation results. 相似文献

Seismic structural reliability using different nonlinear dynamic response surface approximations 总被引:2,自引:1,他引:1
Performance-based design in earthquake engineering should be approached as an optimization process for optimum design parameters, in order to achieve satisfactory performance over the service life. Each of the specified performance criteria should be met with a prescribed minimum reliability and, given these constraints, a minimum or optimum total cost may be sought. The reliability estimations involve a nonlinear analysis for the dynamic responses of the structure, calculated via a step by step procedure over the complete earthquake record. This task could be computationally demanding, making unfeasible the direct implementation of a standard Montecarlo simulation. Dynamic responses represented by response surfaces make the simulation and the optimization process much more efficient. This paper presents a comparison between three methods for the implementation of response surfaces: a global approximation of a deterministic database, local interpolation of that database, or using artificial neural networks. The comparison uses, as an example, a 5-story reinforced concrete building. The results show good agreement between the methods and the paper discusses their corresponding advantages and limitations. 相似文献

This paper describes a process used to develop and test a framework to produce thermal simulation post-processed information meaningful to building design decision-making. The framework adopts a user-centred approach in which the building designer is considered the ultimate simulation tool user either directly or indirectly when supported by consultants. The framework supports the building designer's ‘modus operandi’ and is developed through a set of interdisciplinary research methods. Participatory Action Research, Thematic Analysis and Grounded Theory are used, together with principles from Information Visualization, dynamic thermal modelling and Building Design, following a design approach to problem-solving taken from the discipline of Interaction Design. The various elements of the framework and their connections are derived from analysis of sequences of design actions made by novice designers undertaking complex design activities. Tests of the framework are undertaken through an online questionnaire and five semi-structured interviews with UK architectural design practices. 相似文献
