New directions in agent-based generative architectural design

The paper discusses the potential of computer agents in form generation in the early stages of the architectural design process. First it discusses the possibility to simulate human behavior by computer agents and reviews the various directions in which computer agents were employed in architectural design. Then, it discusses the difference between form simulation and generation in architectural  design and suggests ways in which computer agents could be employed in architectural design in a generative manner. The suggested ways are examined by several design case studies. The paper concludes with the advantages and limitations of employing agents for form generation in architectural design

Introducing Fabric Materiality in architectural fibre composites

Textiles and architecture have long been associated; second and third skins have provided shelter and protection, since early days of men. The presence of textiles in the world of architecture spans across multiple layers, far beyond the mere usage of the fabric itself as architectural structure. The term of ‘Fabric Materiality’ is suggested to represent the unique qualities of textiles, their associated techniques and tools, assets and design paradigms; it is suggested as a design approach, to be integrated in field of architecture. The research presented in this paper explores the integration of Fabric Materiality in the field of architectural fibre-composites; it suggests an alternative design and fabrication approach in architectural FRP (fibre reinforced polymers), based on textile qualities. The main constituent of the composite material is fibres, mostly applied under the form of fabrics. All standard composite forming processes apply the fabric material over a rigid mould, to obtain its final shape; no traces are left to the textile material qualities. This research suggest the integration of Fabric Materiality in the design and fabrication of architectural FRP. Enhancing its inherent capacity for self-organisation and resilient quality, Fabric Materiality suggest the release from the necessity for moulds. In architecture, this opens wider possibilities for free architectural expression: from complex free-form morphology to surface articulation and a high degree of variation. The paper will start by introducing the concept of Fabric Materiality. It will then demonstrate its integration in architectural FRP through a material system of surface elements (panels), based on pleating manipulation. It will review its qualities of as a new porous matter-structure, of structural capacities

Evidence-Based Design in Architectural Education: Designing the First Maggie's Centre in Israel.

OBJECTIVE: The study examines the integration of the Evidence-based Design (EBD) approach in healthcare architecture education in the context of an academic design studio. BACKGROUND: Previous research addressed the gap between scientific research and architectural practice and the lack of research on the use of the EBD approach in architectural education. METHODS: The research examines an undergraduate architectural studio to design a Maggie's Centre for cancer care in Israel and evaluates the impact of the EBD approach on the design process and design outcomes. The research investigates the impact of the integration of three predesign tasks: (1) literature review of healing architecture research, (2) analysis and comparison of existing Maggie's Centres, and (3) analysis of the context of the design project. RESULTS: The literature review of scientific research supported the conceptual design and development of the projects. The analysis of existing Maggie's centers, which demonstrated the interpretation of the evidence by different architects, developed the students' ability to evaluate EBD in practice critically, and the study of the projects' local context led the students to define the relevance of the evidence to support their vision for the project. CONCLUSIONS: The research demonstrates the advantages of practicing EBD at an early stage in healthcare architectural education to enhance awareness of the impact of architectural design on the users' health and well-being and the potential to support creativity and innovative design. More studies in design studios are needed to assess the full impact of integrating EBD in architectural education

Creating ecologically sound buildings by integrating ecology, architecture and computational design

1. Research is revealing an increasing number of positive effects of nature for humans. At the same time, biodiversity in cities, where most humans live, is often low or in decline. Tangible solutions are needed to increase urban biodiversity. 2. Architecture is a key discipline that has considerable influence on the built-up area of cities, thereby influencing urban biodiversity. In general, architects do not design for biodiversity. Conversely, urban conservation planning generally focuses on the limited space free of buildings and does not embrace architecture as an important discipline for the creation of urban green infrastructure. 3. In this paper, we argue that the promotion of biodiversity needs to become a key driving force of architectural design. This requires a new multi-species design paradigm that considers both human and non-human needs. Such a design approach needs to maintain the standards of the architectural profession, including the aim to increase the well-being of humans in buildings. Yet, it also needs to add other stakeholders, organisms such as animals, plants and even microbiota. New buildings designed for humans and other inhabitants can then increase biodiversity in cities and also increase the benefits that humans can derive from close proximity to nature. 4. We review the challenges that this new design approach poses for both architecture and ecology and show that multi-species-design goes beyond existing approaches in architecture and ecology. The new design approach needs to make ecological knowledge available to the architectural design process, enabling practitioners to find architectural solutions that can facilitate synergies from a multi-species perspective. 5. We propose that a first step in creating such a multi-species habitat is the design of buildings with an ecolope, a multi criteria-designed building envelope that takes into account the needs of diverse organisms. Because there is no framework to design such an ecolope, we illustrate how multi-species design needs to draw on knowledge from ecology, as well as architecture, and design computation. 6. We discuss how architectures designed via a multi-species approach can be an important step in establishing beneficial human-nature relationships in cities, and contribute to human well-being and biodiversity conservation.Read the free Plain Language Summary for this article on the Journal blog

Evaluating the Influence of Varied External Shading Elements on Internal Daylight Illuminances

This paper presents an assessment and comparison of the effects of static and kinetic external shading elements on the dynamic measurement of daylighting. For this purpose, we used a method and parametric tool developed previously for the design and analysis of external shading elements in buildings. The proposed approach was used to compare static and dynamic movement scenarios for achieving optimal internal adjusted useful daylight illuminances (AUDI). The current paper presents the results of a methodical analysis, which compared various types of louvers in static and dynamic operation scenarios for a typical office in a Mediterranean climate. The results show that dynamically adjusted louvers perform notably better than fixed or seasonally adjusted modes of operation. The results show that dynamic operation scenarios can increase the AUDI by up to 51%. The results also show that in some conditions the existing rules of thumb fail to predict the correct design approach to louver geometry and that the use of rules of thumb in architectural daylight design needs to be revaluated

Life-Cycle Assessment of Sculptured Tiles for Building Envelopes in Mediterranean Climate

Life-cycle assessments (LCAs) were conducted to evaluate sculptured cement mortar tiles, proposed by Hershcovich et al. (2021), and conventional cement mortar flat tiles for thermal insulation of a typical residential building in Mediterranean climate. The production (P) and operational energy (OE) stages were compared between the sculptured tiles and the conventional flat tiles. The P stage used Portland cement with 95% clinker (CEM I) and Portland limestone cement with 65% clinker (CEM II). The OE stage used 31% coal, 56% natural gas, and 13% photovoltaic (PV) (adopted in 2020) and 8% coal, 57% natural gas, and 35% PV (planned for 2025). The ReCiPe2016 single-score method was used to assess environmental damage over short (20 years), long (100 years), and infinite (1000 years) time horizons of living pollutants. The results show that the use of sculptured tiles caused environmental damage in the short time horizon and environmental benefits in the long and infinite time horizons in the 2020 scenario, while it led to environmental benefits only in the infinite time horizon in the 2025 scenario
