Building design is a highly interdisciplinary research field integrating technological, architectural, structural, social and other aspects. Participatory design, or co-design, already used in other disciplines, is now facilitated by the diffusion of Building Information Modelling which offers greater control of the interdisciplinary aspects in building design. But unlike other disciplines, architecture is characterized by a high number of requirements, partly formalizable, quantifiable and optimizable and partly only intuitive. Furthermore is difficulty to employ a collaborative design framework because designer and end user work on different knowledge levels: one works on satisfying classes of requirements, and the other is unable to abstract his needs and therefore properly formalize requirements or desires. The use of simple parametric models in the pre-design phase, based on algorithms capable of generating geometries dependent on multiple modifiable variables, could overcome this problem.This paper offers a preliminary investigation on the possibility of integrating bottom-up design aspects by giving parametric models to possible end users and allowing them to explore the design space, identifying preferential outputs and overcoming some of their technical gaps. Working in parametric environments in the pre-design phase opens to the integration of tools such as evolutionary multiobjective optimization algorithms (EMOA). New fitness functions can be defined to bring design closer to the end users’ proposed outputs without neglecting performance optimization, which is typical in parametric design. The framework proposed differs from existing “product configurator”, used in industrial design, which allows the personalization of aesthetic characteristics. This paper aims at a greater understanding of the end user’s will for satisfying them better in the subsequent design phases.The technological tools currently available to make this framework possible will be analysed, identifying shortcomings and problems, along with methodological implications.

AbstractIn mass customization, software configurators enable novice end-users to design customized products and services according to their needs and preferences. However, traditional configurators hardly provide an engaging experience while avoiding the burden of choice. We propose a Design Participation Model to facilitate navigating the design space, based on two modules. Modeler enables designers to create customizable designs as parametric models, and Navigator subsequently permits novice end-users to explore these designs. While most parametric designs support direct manipulation of low-level features, we propose interpolation features to give customers more flexibility. In this paper, we focus on the implementation of such interpolation features into Navigator and its user interface. To assess our approach, we designed and performed user experiments to test and compare Modeler and Navigator, thus providing insights for further developments of our approach. Our results suggest that barycentric interpolation between qualitative parameters provides a more easily understandable interface that empowers novice customers to explore the design space expeditiously.

Participatory design is a technique which is being used by system designers to involve the end users and product owners throughout the design process. Even though utilizing this approach brings customers to the design process, implementing it requires a budget, a place, time, and other resources. This chapter demonstrates a model-based approach to facilitate the selection of interviews for each design phase such as listing elements for the interface, choosing location for components, making decision for the general look of the component, finally making the component interactable. Interface designers can use the model to choose different type of interview method for different design phases such as interface components, sketching, lo-fi prototyping and hi-fi prototyping, according to their resources. The research focus is on four different participatory design interview method, which are GUI-ii face-to-face, GUI-ii screen-sharing, GUI-ii Ozlab, and traditional face-to-face interview.

AbstractIndustrial buildings play a major role in sustainable development, producing and expending a significant amount of resources, energy and waste. Due to product individualization and accelerating technological advances in manufacturing, industrial buildings strive for highly flexible building structures to accommodate constantly evolving production processes. However, common sustainability assessment tools do not respect flexibility metrics and manufacturing and building design processes run sequentially, neglecting discipline-specific interaction, leading to inflexible solutions. In integrated industrial building design (IIBD), incorporating manufacturing and building disciplines simultaneously, design teams are faced with the choice of multiple conflicting criteria and complex design decisions, opening up a huge design space. To address these issues, this paper presents a parametric design process for efficient design space exploration in IIBD. A state-of-the-art survey and multiple case study are conducted to define four novel flexibility metrics and to develop a unified design space, respecting both building and manufacturing requirements. Based on these results, a parametric design process for automated structural optimization and quantitative flexibility assessment is developed, guiding the decision-making process towards increased sustainability. The proposed framework is tested on a pilot-project of a food and hygiene production, evaluating the design space representation and validating the flexibility metrics. Results confirmed the efficiency of the process that an evolutionary multi-objective optimization algorithm can be implemented in future research to enable multidisciplinary design optimization for flexible industrial building solutions.

Design For Maintainability

Incorporating maintainability during the building design is essential to increase overall performance of the building including quality and cost as; the management and operation process of facilities can have a significant impact on cost, health and safety, energy and quality. As a result, a more effective and efficient building facility will be turned over during the post occupancy stage. Literature review reveals that there is a need to implement maintainability during the building design phase; mainly due to the increasing life-cycle cost of the building facilities. A critical review of the literature has been carried out to explore the consideration of maintainability during the building design and subsequently identifies a set of criteria and indicators to be applied during the building design phase to achieve cost effective building maintenance. Thus, this paper opted a four-round Delphi questionnaire survey to identify the relevant design for maintainability criteria and indicators to achieve cost effective building maintenance. 8 designs for maintainability criteria along with the indicators for each of the criterion have been identified. These design for maintainability indicators help the building architects to incorporate maintainability practice during the building design phase and thus help to achieve cost effective maintenance. This paper aims to address the long pending quest of incorporating maintainability during the building design phase and consequently achieve cost effective building maintenance.

We address the design issue of mundane and strategic work in collaborative design. We do so through an examination of a series of participatory design activities in building a flagship library of the future. Both strategic and mundane work are found to permeate the processes, results, and further uptake of collaborative design outcomes as internal issues of user involvement, and not just as external context or excludable routine execution, which has been the prevailing view to them in design research to date.

BACKGROUND Advancements in supporting personalized healthcare and wellbeing using virtual reality (VR) has created opportunities to use immersive games to support a healthy lifestyle for persons living with dementia (PLWD) and mild cognitive impairment (MCI). Collaboratively designing exercise-video games (exergames) as a multi-stakeholder team is fundamental to creating games that are attractive, effective, and accessible. OBJECTIVE This research explores the use of participatory design methods that involve PLWD in long-term care facilitates, exercise professionals, content developers, game designers, and researchers in the creation of VR exergames targeting physical activity promotion for PLWD/MCI. METHODS Conceptualization, collaborative design, and playtesting activities were carried out to design VR exergames to engage PLWD in exercises to promote upper-limb flexibility, strength and aerobic endurance RESULTS Our results demonstrate how different stakeholders contribute to the design of VR exergames that consider/complement complex needs, preferences, and motivators of an underrepresented group of end-users as well as game design elements that reflect feedback for therapists and researchers. CONCLUSIONS This study provides evidence that collaborative multi-stakeholder design results in more tailored and context-aware VR games for PLWD. The insights and lessons learned in from this research can be used by others to co-design games, including remote engagement techniques that were used during the COVID-19 pandemic.

The Right

As we enter the third millennium, many organizations are forced to constantly pursue new strategies to differentiate themselves from their competitors. Examples include offering customers streams of new products and services, as well as continuously seeking to improve productivity, services and the effectiveness of product design, development and manufacturing processes. Consequently, new concepts, approaches and tools are emerging quickly as the globalization trend expands across the world. Product complexity, pressures to reduce production cycle time, the need for stakeholders’ contributions and multinational company as well as consumer requirements create the demand for sophisticated multi-designer collaborative virtual environments where product design can be shared and acted upon (Kunz, Christiansen, Cohen, Jin, & Levitt, 1998; Ragusa & Bochanek, 2001; Anderson, Esser & Interrante, 2003). Thus, researchers and practitioners recognize that collaboration is an essential aspect of contemporary, professional product design and development activities. The design process is collaborative by nature. Collaborative design fosters participation of stakeholders in any form during the design process. The design of a successful product is dependent on integrating information and experiences from a number of different knowledge domains. These domains include consumer (end-user) requirements, industrial designers’ professional design skills as well as manufacturers’ needs. This results in a product that performs at a functional as well as aesthetic level and that can be manufactured by the right process at the right price. End-user involvement is essential to product design, since products that do not achieve consumer satisfaction or meet consumer needs are doomed to fail (Schultz, 2001). Accurate understanding of user needs is an essential aspect in developing commercially successful products (Achilladelis, 1971). Hence, it is very important for industrial designers to gather the end-users’ needs and incorporate them into their designs. The involvement of manufacturers in the initial stages of the domestic product design process can lead to a dramatic reduction in a product’s development lifecycle time, also facilitating the coordination of the purchasing and engineering functions (Bochanek & Ragusa, 2001; Demirbilek, 2001). The increasing complexity of artifacts and the globalization of product development are changing research methodologies and techniques. A prime example of this includes the application of a virtual collaborative design environment (VCDE) for product design and manufacturing. This article focuses on the concept of virtual collaborative design. It describes a research effort to investigate cross-cultural collaboration in product development using online applications for domestic product design. The aim of this research is to investigate issues related to the virtual collaborative design (VCD) process, and to bring an understanding of stakeholder needs during the collaborative design process as well as to improve the relationships between end-users, designers and manufacturers. The article presents findings based on a survey study conducted with four different potential stakeholders: representatives of consumers, software designers, industrial designers and manufacturers.
