summary	The study aimed to develop and test an environmentally friendly, easily deployable, and affordable solution for socio-economically challenged populations of the world. 3D-printing (additive manufacturing) was used as a rapid prototyping tool to develop and test a façade system that would modulate air velocity through modifying nozzle profiles to utilize natural cross ventilation techniques in order to improve human comfort in buildings. Constrained by seasonal weather and interior partitions which block the ability to cross ventilate, buildings can be equipped to perform at reduced energy loads and improved internal human comfort by using a façade system composed of retractable nozzles developed through this empirical research. This paper outlines the various stages of development and results obtained from physically testing different profiles of nozzle-forms that would populate the façade system. In addition to optimizing nozzle profiles, the team investigated the potential of collapsible tube systems to permit precise placement of natural ventilation directed at occupants of the built space.

title	Territories Made by Measure: The Parametric as a Way of Teaching Urban Design Theory
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 494-506
summary	Design tools like Grasshopper are often used to either generate novel forms, to automate certain design processes or to incorporate scientific factors. However, any Grasshopper definition has certain assumptions about design and space built into it from its earliest genesis, when the initial algorithm is set out. Correspondingly, implicit theoretical positions are built into definitions, and therefore its results. Approaching parametric design as a question of architectural, landscape architectural or urban design theory allows the breaking down of traditional boundaries between the technical and the historical or theoretical, and the way parametric design, and urban design history & theory, can be conveyed in the teaching environment. Once the boundaries between software and history & theory are transgressed, Grasshopper can be a way of testing the principles embedded in historical designs and thus these two disciplines can be joined. In urban design, there is an inherent clash between an ideal model and existing urban geography or morphology, and also between formal (qualitative) and numerical (quantitative) aspects. If a model provides a necessary vision for future development, an existing topography then results from the continuous human and natural modifications of a territory. To explore this hypothesis, the “Urban Design Representation” subject in the Master of Urban Design program at the University of Cape Town taught in 2017 & 2018 was approached “parametrically” from these two opposite, albeit convergent, starting points: the conceptual/rational versus the physical/empiric representations of a territory. In this framework, Grasshopper was used to represent typical standards and parameters of modern urban planning (for example, Floor/Area Ratio, height and distance between buildings, site coverage, etc), and a typological approach was adopted to study and “decode” the relationship between public and private space, between the street, the block and topography, between solids and voids. This methodology permits a cross-comparison of different urban design models and the immediate evaluation of their formal outputs derived from parametric data.

title	The Use of High Low Architecture in the Creation of Alternative Construction Elements
source	SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 367-374
summary	This study presents an investigation on how the use of digital tools in the fields of architecture and engineering can help establish a connection between the architectural projects developed within Universities and what is produced by the construction industry, consolidating a critical design process that reflects on the use of current technologies. To do so, it will be necessary to employ knowledge gathered from the intersecting areas of architecture, computation and engineering to rethink the use of common materials directing it towards a non-specialized workforce, a relationship that can be defined as high-low architecture.

title	Parametric Design as Interpreter of the Urban Compositional Problem - One basic application to city block modeling
source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 335-344
doi	https://doi.org/10.52842/conf.ecaade.2018.2.335
summary	The paper explores parametric design technology from an urban design perspective of development. One possible finalization of technique as informer of urban space subdivision is presented, with an eye on geometry and its energy efficiency implications. The recognition of urban space as a field of complex equilibria, where different claims insist on the subdivision process, helps interpret methodology from a critical stance, at least within the margins of selected studies and a partial, yet indicative experiment.

title	Blockerties - The Distributive Design of the Blockchain Technology and its Impact on Urban Form.

summary	This paper aims to link the blockchain technology with property issues and in extend architectural design decisions at the urban scale. In an urban design context, this paper investigates the new potentials of urban form connected to the application of the logic of the blockchain to urban design. With this, the article concentrates on the distributed way of sharing information, with no intent to focus on cryptography issues related to the blockchain. Transferring the blockchain's core concepts of data distribution through ledgers, to patterns of shared and private owned spaces it can lead to what we propose as polyphonic spaces, with overlapping uses. Urban realm, designed as a chain, initiates with the binary condition of private and shared but handles it as a way to interact, through nesting, its initial parts. We think that the blockchain theory is capable of challenging architecture by shifting the weight from individual elements of composition to compound entities (block) that incorporate all the information needed.Please write your abstract here by clicking this paragraph.

summary	House Block was a temporary housing prototype in East London, UK from April to May 2021. The project constituted the most recent in a series of experiments developing Automated Architecture (AUAR) Labs’ discrete framework for housing production, one which repositions the architect as curator of a system and enables participants to engage with active agency. Recognizing that there is a knowledge gap to be addressed for this reconfiguration of practices to take form, this project centred on making automation and its potential for local communities tangible. This sits within broader calls advocating for a more material alignment of inclusive design with makers and 21st Century making in practice (see, for example, Luck 2018). House Block was designed and built using AUAR’s discrete housing system consisting of a kit of parts, known as Block Type A. Each block was CNC milled from a single sheet of plywood, assembled by hand, and then post-tensioned on site. Constructed from 270 identical blocks, there are no predefined geometric types or hierarchy between parts. The discrete enables an open-ended, adaptive system where each block can be used as a column, floor slab, wall, or stair—allowing for disconnection, reconfiguration, and reassembly (Retsin 2019). The democratisation of design and production that defines the discrete creates points for alternative value systems to enter, for critical realignments in architectural production.

doi	https://doi.org/10.52842/conf.ecaade.2018.1.743
summary	This paper describes the methods and results of an experimental workshop held at the Department of Architecture of PUC-Rio devoted to exploring design alternatives and digital fabrication techniques to produce concrete façade elements for the Consulate General of Portugal building in Rio de Janeiro, Brazil. The workshop aimed the adoption of advanced computer-aided design and production methods within a rare and innovative university-industry collaboration context in Latin America. The paper aims to discuss contemporary concrete casting methods and its applicability, as well as the achievements and pitfalls of the adopted technique. The results are discussed under the light of Antoine Picon's notion of contemporary ornament and Branko Kolarevic's perspectives on digital imprecision.

summary	This research developed an immersive, multi-dimensional Virtual Experience of the 'Gordon Wilson Flats', a Modern apartment block constructed during the 1950s in Wellington, New Zealand. The project explored methods to virtually reconstruct the spatial qualities of the building and document the flats in both their current and original states within the context of Wellington City. This digital heritage project documents both the tangible and intangible characteristics of the building to inform public discussion focused upon the flats. This approach was in an effort to capture the effect of time on the buildings tangible elements, and with the addition of oral histories, develop a narrative which is intended to facilitate architectural understanding and heighten engagement within the immersive virtual environment. This paper presents a digital methodology for the creation of a digital heritage experience with the purpose of engaging and informing public discussion.

title	Robotic Equilibrium: Scaffold Free Arch Assemblies
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 342-349

summary	Compression only arch structures are structurally highly efficient in force equilibrium. However, the material efficiency is offset by the traditional use of scaffolds to position materials and counter the out of equilibrium forces during assembly. We introduce a method of sequentially assembling compression only structures without a scaffold by robotically maintaining the compression equilibrium in every step. A two-arm collaborative robotic setup was used to maintain force equilibrium throughout arch assembly with the arms taking turns first hot wire cutting and placing blocks and providing a temporary scaffold to support the arch end point. To test the approach, a single catenary arch was generated using form-finding techniques and sequentially built from foam blocks. Moving forward we show the relationship between the joint valence (largest number of joined branches) of a multi-branched structure and the minimum number of robotic arms required for assembly using our initial technique. With only two robotic arms available, the technique was further developed to reduce the required number of arms per arch branch from two to one by attaching caterpillar tracks at the block supporting end effector. This allows a human to load the next block and the arm to move forward along the arch while maintaining equilibrium. Results show that robotic equilibrium scaffold free arch assembly is possible and can reduce scaffold waste and maintain the material efficiency of compression only structures. Future work will explore further applications of assistive robotics in construction replacing static construction aids with dynamic sensory feedback of equilibrium forces.
