title Multi-objective Optimisation of Building Geometry for Energy Consumption and View Quality

summary In property development, the view quality contributes significantly to the property value. In many cases, the architect is constrained by the property developer to take full advantage of the view by designing large glazed facades ignoring the consequence on the energy consumption of the building caused by the conflicting orientation of the view. This paper presents a design tool to help the architect interactively explore different building and window geometries that trade-off energy consumption (kWh) and view quality (€). This design tool allows interaction with parametric building geometry, simulation of energy consumption and view quality, and an optimisation search engine. The simulation of the view quality quantifies a view according to the visibility and quality of its contents by using a novel view-scoring method. The design tool is tested with both north-oriented and south-oriented views and produces a Pareto front from which resulting geometries are visualised.

title Aviva Stadium: A case study in integrated parametric design
source International Journal of Architectural Computing vol. 9 - no. 2, 187-204
summary The nature of large complex buildings requires specialized skills across a multi-disciplinary team and high levels of collaboration and communication. By taking a parametric approach to design and construction, high quality results can be delivered on budget on time. This type of approach facilitates the opportunity for design teams to work in an iterative manner.A parametric model reduces the time associated with complex design changes while providing a centralized method for coordinating communication. In this paper the recently completed Aviva Stadium is used to illustrate the ways in which these benefits manifest themselves on built work.The authors identify the moments in the design and construction process that truly justify the effort in implementing a parametric approach. By approaching design in this way a “design conversation” can take place between parties involved, resulting in a better building.

title Designing with Discrete Geometry
source Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 513–522
summary There has been a shift in aesthetics from the modern orthogonal building envelope to more elaborate curved and folded forms. Non_orthogonal forms are often associated with complete freedom of geometry, entrusting the advancement in custom manufacturing and robotic fabrication of one-off building parts to realise the design. This paper presents a methodology that allows non_orthogonal surfaces to be designed using a constrained library of discrete, tessellating parts. The method enables the designer both to produce ‘approximations’ of freeform designs in a top_down manner or to generate ‘candidate’ designs in a bottom_up process. It addresses the challenge in the field of design engineering to generate architectural surfaces which are complex, yet simple and economical to construct. The system relates to the notion that complexity derives from simple parts and simple rules of interaction. Here complexity relates to the holistic understanding of a structure as an interaction between its local parts, global form and visual, as well as functional performance.

title Digital Architectonics in Practice: Aarhus Botanical Garden Hothouse Competition
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 673-680

summary Digital Architectonics is a term which refers to the application of digital technology to the architectural design process. This paper presents a new Digital Architectonics software tool, which allows various methods of 3D modeling, formfinding and optimization to be combined to generate and develop concept- and scheme-design options. The practical use of the software is demonstrated through the case study of the recent architectural competition to design a new hothouse for the Aarhus University Botanical Garden.

title Aviva Stadium: A parametric success
source International Journal of Architectural Computing vol. 9 - no. 2, 167-186
summary The Aviva Stadium, Dublin, is the first stadium to be designed from start to finish using commercially available parametric modelling software. A single model in Bentley’s Generative Components was shared between architects and engineers, which allowed the optimised design of form, structure and fac_ade. The parametric software was extended where necessary to integrate with structural analysis and to automate fabrication. By reducing the overhead associated with design iterations, this approach allowed detailed exploration of options and early identification and resolution of potential problems. In this paper, the authors add to the body of scientific knowledge by describing in detail the methods which led to the construction of the Aviva Stadium.This paper is written in light of the completed building and provides information on the generation and control of the envelope geometry, development and analysis of structure and documentation for construction.Whilst these components have been discussed independently previously [1–4], here these aspects are drawn together for the first time and are presented alongside thoughts on the manufacturing and construction processes from the project architect.
