142 – Searching for Designs In-Between: Exploration of Design Space Using a 3D Printing-Inspired Evolutionary System

The use of evolutionary methods in design and art is increasing in diversity and popularity. Approaches to using these methods for creative production typically focus either on optimisation or exploration. In this paper we introduce an evolutionary system for design that combines these two approaches, enabling users to explore landscapes of design alternatives using design-oriented measures of fitness, along with their own aesthetic preferences. We test our methods using a biologically-inspired generative system capable of producing 3D objects that can be exported directly as 3D printing toolpath instructions. For the search stage of our system we combine the use of the CMA-ES algorithm for optimisation and linear interpolation between generated objects for feature exploration. We investigate the system’s capabilities by evolving highly fit artefacts and then combining them with aesthetically interesting ones.

063 – Parametric Design for Industrial Products: Taking Ergonomic Seat Design as an Example

Wednesday 31 March, 11:30, Session 5A

Shaoting Zeng, Tsinghua University
Song Qiu, Tsinghua University

The main contents of this paper are the parametric design and its applications in industrial design, taking the ergonomic chair as the main design research carrier, conducting experimental study explored the parametric industrial product design procedures and methods based on personalized design notion of “Form follows behaviors”. The research map focused on two fundamental parts of parametric design definition: the construction of the parameter relationship and the acquisition of parameters. The first part, through design space exploration (DSE) to translate the design problem into parameters relationship and variable ranges. The second part, using various software and hardware tools (Grasshopper, Arduino with pressure sensors, Kinect etc.) to facilitate parameter acquisition and its application in the 10-person customer-driven experiments to the resulting design models and user datasets. Finally, through the formulation of quantitative evaluation for 110 sets of user data and models, selecting the best design solution for 3D printed prototype for the user test.

038 – From Exploration to Interpretation: Adopting Deep Representation Learning Models to Latent Space Interpretation of Architectural Design Alternatives

Wednesday 31 March, 11:45, Session 5A


An informative interpretation of the hyper-dimensional design solution space can potentially enhance the cognitive capacity of designers with respect to both conventional design practice and the research domain of computational-aided generative design. However, the hitherto research of design space exploration has had limited focus on the interpretation of the hyper solution space per se due to the knowledge gap pertaining to representation and generation. Representation learning techniques, as a core paradigm in the statistically empowered domain of machine learning, possess the capability of extracting a convoluted probabilistic distribution of hyperspace with latent features from unorganized data sources in a generalized manner, which can be an intuitive modus operandi for a structural interpretation of the intricate latent design solution space and benefit the challenging task of architectural design exploration. We examine and demonstrate the potential capabilities of representation learning techniques for the interpretation of latent architectural design solution space with consideration of disentanglement and diversity.

099 – A Graph Theoretic Approach for the Automated Generation of Dimensioned Floorplans

Wednesday 31 March, 12:00, Session 5A

Krishnendra Shekhawat, BITS Pilani

The automated generation of architectural layouts is an intensively studied research area where the aim is to generate a variety of (initial) layouts for the given constraints which can be further modified by designers and architects. From a mathematical perspective, one of the well-known constraints is given in the form of an adjacency graph which represents the adjacency relations of the given rooms and problem is to generate multiple layouts satisfying the adjacency relations. In the literature, the adjacency graph is usually taken as a bi-connected planar triangular graph. In this paper, we present the results of a prototype GPLAN that generates multiple dimensioned layouts for any given planar graph. The larger aim of this work is to develop software that can produce a variety of architecturally acceptable floorplans corresponding to the given constraints.

052 – Deep-Performance: Incorporating Deep Learning for Automating Building Performance Simulation in Generative Systems

Wednesday 31 March, 12:15, Session 5A

Shermeen Yousif, Florida Atlantic University

In this study, we introduce a newly developed method called Deep-Performance, to enable automatic environmental performance simulation prediction without the need to perform simulations, by integrating deep learning strategies. The aim is to train neural networks on datasets with thousands of building design samples and their corresponding performance simulation. The trained model would offer performance prediction for design options emerging in generative protocols. The research is a work-in-progress within a broader project aimed at automating buildings’ environmental performance evaluations of daylight analysis and energy simulation, using deep learning (DL) models. This paper focuses on the implementation of a supervised DL method for automating the retrieval of daylight analysis metrics, targeting successful daylight design and higher building enclosure efficiency. We have further improved a Pix2Pix model trained on 5 different datasets, each containing 6000 paired images of architectural floor plans and their daylight simulation metrics. In the inference phase, the model was able to accurately predict the daylight simulation for unseen sets of floor plans. For validation, two quantitative assessment metrics were followed to assess the predicted daylight performance against the daylight performance simulation. Both assessment metrics showed high accuracy levels.
