In response to the inadaptation and difficulties for architects in the use of engi- neering simulation tools and optimization methods, a method is proposed for graphical perfor- mance evaluation achieved with a developed plugin for Grasshopper as an architect-friendly tool to support design exploration in early stage. The proposed method follows forward work- flow for interactive feedback of performance, focusing on thermal and visual comfort upon a variety of design options. A case study of shading design is demonstrated. The demonstration illustrated an intuitive and graphical process for qualitative performance evaluation, which is assisted by an overall ratio ranking the integrated performance of design options for a quan- titative comparison. Compared with engineering optimization methods that focus on optimal performance-based solutions, the proposed method presented graphical feedbacks on design performance that are interactive with the designer for performance-informed decision mak- ing. In this way, the proposed method stimulates the effective and positive application of en- gineering tools and judgment at the early stage of iterative design.

Building performance has become a major concern in architectural design due to increasing requirements for energy efficiency and high-performance buildings (Nguyen et al., 2014). Building performance simulation (BPS) is, therefore, more helpful in the early design stage explore more design alternatives (Han et al., 2018), and its best efficiency on energy, environmental, and comfort analysis (Athienitis and O’Brien, ۲۰۱۵; Konis et al., 2016). Also, it has been integrated with the optimization design study for optimal performance-based design solutions. With the development of computer science and simulation tools, BPS has received growing attention in the architectural design process, and the number of simulation tools has been
developed for this purpose. In the last decade, there have been nearly two hundred BPS tools. Meanwhile, studies on BPS and optimization methods in building design have been in a dramatically rising trend (Evins, 2013; Machairas et al.,
2014; Nguyen et al., 2014), some of which are particularly aimed at the early design stage for architects. Li. et al. developed a bidirectional method in the early design stage that combines the designer-orientated and performance- orientated modes for both real-time feedback and optimal solution search (Li et al., 2018). Konis et al. developed a framework and workflow that enables de- signers to examine building form by passive performance in the early design stage (Athienitis and O’Brien, ۲۰۱۵). Attia et al. present a simulation-based decision support tool focusing on informing the design by building performance simulation other than evaluating design alternatives (Attia et al., 2012a). Lobaccaro at al. Proposed a parametric- driven workflow that enables multi-objective optimization as well as life cycle assessment by several performance indicators (Lobaccaro et al., ۲۰۱۸). Youssef et al. devel- oped a BPS method for building envelope with integrated photovoltaic using the architectural theory of shape grammar (Youssef et al, ۲۰۱۵, ۲۰۱۸). Ochoa et al. devel- oped a tool that provides intelligent solutions in fa¸cade design for architects to choose (Ochoa and Capeluto, 2009). Shi et al. developed a performance-driven design workflow on the Rhinoceros and grasshopper platform, which is ex- pected to be more familiar to architects (Shi and Yang,
However, BPS and automatic optimization methods are found to remain in low usage by architects. It is reported that 74% of architects do not use BPS in their day-to-day practice (Soebarto et al., 2015), the part of BPS and opti- mization are often outsourced to engineers or external experts other than architects themselves (Flager et al.,
2009; Konis et al., ۲۰۱۶; Soebarto et al., ۲۰۱۵). It is argued that architects have difficulty in the use of
simulation tools and optimization methods, and present BPS cannot adequately address the needs of architects and neither fully accord with the general logic flow of archi- tectural design (Østergard et al., 2016; Shi et al., 2016). Barriers, therefore, exist to reduce or hinder BPS to be employed in architectural design.
The barriers may lie in three aspects of design workflow, presentation of simulation feedback and optimization method. First, regarding the design workflow, forward and inverse workflow are generally the two modes of adopted with the integration of BPS (Li et al., 2018). And the inverse workflow is increasingly proposed that regards the design process and design outcome as a performance-driven workflow and a performance-orientated output by genetic algorithms. Nevertheless, when design decisions are mostly objectively evaluated and dominated by quantifiable fac- tors, the designers’ subjective and manual intervention design are inadequately addressed during the design pro- cess. Second, as for the design optimization, the complexity of existing engineering parametric or sensitivity analysis increased the difficulty and required skills for ar- chitects, which caused the most complaints by architects (Kanters et al., 2014). And representation and interpreta- tion of simulation results are often found difficult to inform the architects on decision making due to complexity and excessive information (Attia et al., 2009; Donn et al., 2009; Weytjens et al., 2011).
Given the above-existing incompatibilities of BPS in the design process, this study, therefore, aims to propose a performance-informed method by architect-friendly inter- face with graphical performance feedback in the early- design stage, targeting compatibility with both the archi- tects’ conventional workflow and the advantage of infor- mation from BPS. In particular, this study focuses on the early-stage design of exterior fixed shading focusing on the thermal and visual comfort incorporating solar irradiation, which has been a key concern of both architectural design and engineering optimization design using BPS.
