以前的研究表明，需要一个工具来评估建筑设计的各个方面在早期设计阶段。本文提出了一种基于多属性的工具，以满足这一需求。该工具允许用户在进行建筑设计的同时评估建筑物的功能性、经济性和性能。为了说明该工具的机制，本文详细介绍了成本估算模块，该模块可以在流行的3D建模环境中快速直观地探索早期设计。从3D模型中自动提取测量值，并实时修改轮廓驱动估计值。数据模型使用灵活的单位费率系统，可以很容易地扩展到其他估计维度，如碳估计和废物估计。本文所示的方法是适用于3D建模环境，支持自由形式的几何体量的目的以外的一个选择本研究。
Previous studies reveal the need for a tool to evaluate various aspects of building design in early design stages. This paper proposes a multi-attribute based tool to address this need. The tool allows users to evaluate the functionality, economics and performance of buildings concurrently with building design. To illustrate the mechanics of the tool, the paper details the cost estimation module that enables quick and intuitive exploration of early stage design in a popular 3D modelling environment. Measurements are automatically extracted from 3D models and profile driven estimates are revised in real-time. The data model uses a flexible unit rate system that can easily be extended to other estimate dimensions such as carbon estimates and waste estimation. The approach illustrated in this paper is applicable to 3D modelling environments that support free form geometry for massing purposes other than the one chosen for this study.
