ABSTRACT

Given climate change and rapid global development, buildings must meet increasingly stringent environmental performance goals. Although numerous building simulation software assess energy performance, few inform the early stages of design when critical decisions impacting energy use and carbon footprint are made. Underrepresented early design simulation software could potentially significantly improve the environmental performance of buildings. This paper presents the SEED Framework for multi-objective early design decision-making that utilizes EnergyPlus-based building energy, structural finite element analysis, and Radiance-based daylighting simulations. When furnished with basic inputs, the SEED Framework generates numerous design options ranked by energy use, embodied carbon, construction cost, and daylighting metrics. A case study of a hypothetical mid-sized office building modelled in the Boston, Washington D.C., and Phoenix, USA climates demonstrates how the framework can guide decisions throughout pre- and schematic design phases. This framework aims to assist architects in designing high performance buildings within project and budgetary constraints.

摘要

鉴于气候变化和全球快速发展，建筑物必须满足日益严格的环境绩效目标。尽管许多建筑物模拟软件评估能源性能，但是当做出影响能源使用和碳足迹的关键决策时，很少有人告知设计的早期阶段。代表性不足的早期设计模拟软件可能会显着改善建筑物的环境性能。本文介绍了用于多目标早期设计决策的SEED框架，该框架利用了基于EnergyPlus的建筑能量，结构有限元分析和基于辐射的采光模拟。当提供基本输入后，SEED框架会生成许多设计选项，这些选择选项将按能耗，所含碳，建筑成本和采光指标进行排名。以在波士顿，华盛顿特区和美国凤凰城的气候为模型的假设中型办公楼的案例研究表明，该框架如何在整个前期和示意图设计阶段指导决策。该框架旨在帮助建筑师在项目和预算限制内设计高性能建筑物。
