Power Harvest : Explorations in Regenerative Energy Technologies within the (post) Colonial Climate Emergency

Moss, Miranda January 2021 (has links)
This design project explores the viability of DIY regenerative energy projects, while challenging Eurocentric scientific and engineering norms within a (post)colonial climate emergency. Intervening at the energy-water-sanitation-agriculture nexus from a socio-ecological standpoint, the aim of the project is to fabricate low cost urine-fed Microbial Fuel Cells using non-specialist materials and equipment, and to visualise/ materialise the energy from the devices in a tangible form, in an inherently pedagogical activity.  Stemming from a concern that high-end investigations into renewable energy technologies are insufficient in tackling sufficient socio-ecological issues in their reductionist approach, the project assesses the possibilities of energy democratization from a synergistic standpoint. Working within the framework of Regenerative Design and Appropriate Technology,  I point out that Western Technological "progress", which is often used as justification and perpetuation of colonial projects, is degenerate and inappropriate, and should be reframed as such.  Translating cutting edge bioenergy research into demystified, easy to replicate forms, a large component of the project consists of an intensive material exploration, with the goal of accessibility over efficiency as the most important factor. Aiming for the research to be distilled into a workshop form, in addition to online documentation hereof, proved beyond the reach of the timeframe. However, as a public introduction to this phase of the projects, research made during the project timeline is artistically articulated and presented to the public within the context of an exhibition, to stimulate public participation with the project and the ideas and issues contained herein.

Méthode de conception de produit intégrant ses services en phase conceptuelle appliquée aux projets de construction / Method for the conceptual phase of an Integrated Product and Service Design applied to Construction Project

Mauger, Cyril 19 December 2014 (has links)
La phase conceptuelle, basée sur des informations imprécises et incomplètes, est à la base de la satisfaction des clients par le futur système. La programmation architecturale se concentre sur une des premières étapes de cette phase dans le domaine de la construction : la définition des besoins d'un bâtiment. Les pratiques et recherches actuelles en Architecture-Ingénierie-Construction ont tendance à être basées sur l'expérience des programmistes et architectes. Elles sont rapidement orientées vers la production de solutions architecturales et avec une formalisation tardive des besoins métiers en exigences bâtiment. La définition des exigences est bien plus développée dans les autres domaines d'ingénierie (i.e. génie mécanique, industriel et logiciel) au sein de théories, modèles, techniques et outils. Ces travaux de recherche visent à proposer un raisonnement de programmation architecturale basé sur ces connaissances en matière d'ingénierie des exigences dans ces autres domaines. La méthodologie suivie pour développer ce raisonnement s'appuie sur une démarche transdisciplinaire basée sur une combinaison de méthodologies issues des Sciences de la Conception. Outre l'identification de langages de modélisation couvrant différent points de vues associées à la programmation architecturale, un manque est identifié en ce qui concerne les concepts définissant l'objet d'étude : la transition entre les concepts d'activité et d'espace. Le concept de ‘‘méta-espace'' est proposé pour combler ce manque ainsi qu'un langage de modélisation permettant l'exploitation des relations entre ces concept. Une formalisation très en amont de la transition des besoins métiers des clients vers les exigences bâtiment est proposée via une démarche conceptuelle résultant de l'ajout du concept de ‘‘méta-espace''. Cette démarche est présentée étape par étape en s'appuyant sur les divers cas d'études traités au cours de la thèse. / The conceptual phase is based on very fuzzy and incomplete information about clients' needs. It constitutes the core of clients' satisfaction about the future system. Architectural programming, or briefing process, focuses on the early stages of the conceptual phase of construction projects, i.e. the requirements definition. Current practices and research in Architecture-Engineering-Construction tend to be experience-based, solution-oriented, and with a late formalisation of business needs into building requirements. The requirements definition is far more supported by theories, models, tools, and techniques in other engineering disciplines (i.e. Mechanical, Industrial, and Software Engineering). This research aims to propose an architectural programming reasoning based on existing requirements engineering knowledge from these other engineering disciplines. The methodology followed to develop this reasoning is a transdisciplinary approach based on a combination of Design Research Methodology, and Design Science. Besides the identification of modelling languages covering different viewpoints associated with the briefing process, a gap is identified regarding modelling constructs associated with a “meta-space” design artefact. This design artefact and its associated modelling language (i.e. the meta-space diagram) support the formalisation of the transition from activities to space. The resulting conceptual framework proposes a step by step early formalisation of the transition from clients' business needs to building requirements. All along the thesis, different case studies are used to illustrate the proposals.
