Currently excessive fossil fuel consumption has become a serious problem. People are searching for new solutions of energy production and there are several options to obtain alternative sources of energy without further devastating the already destroyed environment. One of these solutions is growing microalgae, from which biodiesel can be obtained. The microalgae production is a growing business because of its many useful compounds. In order to collect these compounds microalgae must first be harvested and then dried. Nowadays the solutions used for drying use too much energy and therefore are too expensive and not sustainable. The goal of this project, one of the possible choices during the EPS@ISEP 2013 Spring, was to develop a solar microalgae dryer. The multinational team involved in its development was composed of five students, from distinct countries and fields of study, and was the responsible for designing a solar microalgae dryer prototype for the microalgae laboratory of the chemical engineering department at ISEP, suitable for future tests and incorporating control process (in order not to destroy the microalgae during the drying process). The solar microalgae dryer was built to work as a distiller that gets rid of the excess water from the microalgae suspension. This paper presents a possible solution for this problem, the steps to create the device to harvest the microalgae by drying them with the use of solar energy (also used as an energy source for the solar dryer control system), the technologies used to build the solar microalgae dryer, and the benefits it presents compared to current solutions. It also presents the device from the ethical and sustainable viewpoint. Such alternative to already existing methods is competitive as far as energy usage is concerned.

Purpose – This study seeks to provide a review of the background and context to the engagement of RICS members with the sustainability agenda, and to examine the extent to which the surveying profession uses relevant information, tools and techniques to achieve the key objectives of sustainable development (or sustainability). Design/methodology/approach – The paper analyses results from a major international online survey of 4,600 RICS respondent members, supported by 31 structured telephone interviews. Findings – The results suggest that, although sustainability is highly relevant to RICS members’ work, a lack of knowledge and expertise is making it more difficult for sustainability tools and other information to be used effectively. Research limitations/implications – The survey is based on a substantial number of responses which are broadly representative of the global RICS population. A key implication is that “laggard” faculties include the disciplines of commercial property and valuation. Practical implications – The research suggests that key stakeholders must work together to provide better information, guidance and education and training to “hardwire” the sustainability agenda across RICS faculties. Originality/value – This is the first truly global survey of its kind and focuses particularly on those faculties that play a major role in property investment and finance (i.e. valuation and commercial property), comparing their position with that of other faculties in an international context.

Purpose – The purpose of this paper is to present the concept of global “strategic sustainability”, represented by a conceptual framework, the “spheres of strategic sustainability”. The paper examines routes, solutions and a vision for corporate strategic sustainability in the macro context of the global physical environment and the planet. This builds on previous research identifying key drivers and strategies for corporate sustainability. Design/methodology/approach – The paper is conceptual in nature and underpinned by Gaia theory, ecosystems theory and the laws of thermodynamics. These three offer specific foci for sustainability research including holism, integration and synthesis: without which, sustainability research would be difficult to achieve. Findings – The paper identifies two major domains – “corporate” and “consumer” strategic sustainability. It examines the corporate domain in which routes are identified through responses to existing globalisation, corporate strategy and corporate culture. Research limitations/implications – The paper provides insight and preliminary conceptual development towards a full theoretical model of corporate and consumer strategic sustainability. The framework will guide future conceptual and empirical investigations and broaden and deepen our understanding of how firm's can construct strategic business models that incorporate sustainability. Originality/value – The paper offers a conceptual framework that develops the concept of “corporate strategic sustainability” and provides positive, practical solutions to incorporating sustainability into business models. It also challenges the current dominant socio-economic paradigm and sets the scene for a more positive eco-paradigm that serves the present and future needs of the planet, environment, businesses and human society.

The current beverage (cylindrical shape) cans are stacked on each other after production, thus consuming a lot of space. Indirectly, this could result to high carbon emission during transportation. The problem is how to minimize the carbon emission based on different contradicting viewpoints. It was suggested that a conical shape of "the beverage can" could be a solution for the space optimization of empty beverage can transportation, thus creating the title for this research “Conical aluminum can”. They would be stacked inside each other before filling. This was based on design for sustainability and the consumer perspective and willingness toward sustainability. However, it was noticed that the industry is unwilling to incorporate this change.

A proposal for a global analysis of sustainability in projects related in oil facilities is presented. By considering economic, environmental and social aspects in the early stages of design, the suggested method is more comprehensive and can be used to complement the analysis commonly applied in the petroleum industry, such as: Study of Technical and Economic Feasibility; Environmental Impact Assessment and Risk Analysis. Several authors, associations, certification bodies and oil companies suggest different approaches to study sustainability in some specific activities (or industries). In this study, a checklist of significant sustainability aspects for the oil industry (surface facilities) was assembled. In addition, a matrix was developed to assess the sustainability items relevant to these projects. In this work, the checklist interacts with the matrix to perform a "Preliminary Analysis of Sustainability of the Enterprise" (APSE). This method allows the identification of aspects that contribute significantly to global sustainability. From this analysis, which includes economic, social and environmental aspects, is built a report that is used to analyze qualitatively and quantitatively the impact of the sustainability aspects of the project. In this analysis are identified items that strongly influence the economic, social or environmental aspects and evaluated alternatives that can increase the overall sustainability of the project. Finally, the alternatives that can be used to indicate the most sustainable option are identified. This method was applied in a project (design) of a small offshore platform. This case study shows how the APSE can contribute to the identification of sustainability initiatives for the enterprise. The results showed that relevant aspects can contribute decisively to global sustainability. Finally, it was observed that the proposed method can contribute to increased rates of sustainability, even after application of analysis commonly used in these projects

This research is based on the reflection about the current culture of fruit packages, the standard that states the format and its materials, in the context of a contemporaneous design. It covers space representation issues, material and form representation in addition to the conditioner of the format of the pack as standard load and not the product itself. To analyze the factors related to packaging, we studied the systematic thinking, holistic or ecological and data were arranged in the form of systemic mind maps. The research aims to contribute with information to help in diagnosing the problem in its complexity and interconnected web of factors in order to facilitate better planning of packaging for fruit culture in a future sustainable society.

Purpose: Neo-institutional theory suggests that organisations change occurs when institutional contradictions, caused by exogenous and endogenous dynamics, increase over time to the point where change can no longer be resisted. Human praxis will result, but only when sufficiently powerful interests are motivated to act. This paper aims to examine the role that the accreditation of business schools can play in increasing institutional contradictions and hence fostering organisational change towards stakeholder engagement and engagement with social responsibility and sustainability issues. Numerous accreditations are promulgated within the higher education and business school contexts and a number of these relate to, or have aspects that relate to, ethics, social responsibility and sustainability. Design/methodology/approach: The paper first analyses the take up of accreditations across UK business schools and then uses a case study to illustrate and explore stakeholder engagement and changes related to ethics, social responsibility and sustainability linked to accreditation processes. Findings: Accreditations are found to be an increasingly common interest for UK business schools. Further, a number of these accreditations have evolved to incorporate issues related to ethics, social responsibility and sustainability that may cause institutional contradictions and may, therefore, have the potential to foster organisational change. Accreditation alone, however, is not sufficient and the authors find that sufficiently powerful interests need to be motivated to act and enable human praxis to affect change. Research limitations/implications: This paper draws on previous research that considers the role of accreditation in fostering change that has also been carried out in healthcare organisations, public and professional bodies. Its findings stem from an individual case study and as such further research is required to explore whether these findings can be extended and apply more generally in business schools and universities in different contexts. Practical implications: This paper concludes by recommending that the newly established UK & Ireland Chapter of PRME encourages and supports signatory schools to further embed ethics, social responsibility and sustainability into all aspects of university life in the UK. This also provides an opportunity to engage with the accrediting bodies in order to further support the inclusion of stakeholder engagement and issues related to this agenda in their processes. Originality/value: This paper contributes by introducing accreditation as an institutional pressure that may lead indirectly to organisational change and supports this with new evidence from an illustrative case study. Further, it draws on the role of institutional contradictions and human praxis that engender organisational change. © Emerald Group Publishing Limited.

In this thesis I investigate issues of post-war concrete buildings and how we can both add value and make adaptable what we have traditionally defined as not valuable and not adaptable. 55% of United States’ commercial building stock was built between the years of 1960 and 1980, leaving 36 billion square feet of building material to be adaptively reused or at the bottom of a landfill. Currently, our culture does not value many character defining features of these buildings making the preservation of these buildings difficult, especially at this 50 year critical moment of both the attribution of a “historic” status and time when major renovation of these buildings needs to occur. How can architects add value to a building type, sometimes called “brutalist”, that building culture currently under values and thinks is “obsolete”? I tested this hypothesis using the James Forrestal Building in Washington D.C. After close study of the obsolescence, value,history and existing conditions, I propose a design that adds value to Southwest Washington D.C. and may serve as an example for post-war renewal around the country.

This paper aims to analyse the birth and evolution of design with concerns over sustainability, in the context of social and civilizational changes experienced since the industrial revolution, with particular focus since the post-war period and in the context of sustainable development. It will examine several factors that influenced this design approach and that drove its evolution through different stages of maturity and complexity. It will analyse the various forms of design with environmental concerns, as well as the inclusion of other criteria in the context of sustainability, namely social ones. The aim is to settle knowledge that can allow us to draw some lessons to meet the challenges we face today.

This qualitative inquiry explored 7 undergraduate students' attitudes, habits, and knowledge of consumerism, fashion design, and sustainability. The postmodern study employed crystallization as its methodological framework to gain insight into how participants' knowledge is manifested in their daily habits, and used 4 methods of data gathering: semistructured interviews, visual exercises, journal entries, and the researcher's own reflections. Four major themes emerged: Knowledge-Concepts Linked and Fragmented; Dissonance Between Knowledge Versus Attitudes and Consumer Habits; Surrendering to the Unsustainable Structures; Design Process and Caring Attitude. Findings indicate that participants possessed some knowledge of sustainability but lacked a well-rounded understanding of environmental and humanitarian implications of Western consumer society. Findings also reveal a dissonance between participants' knowledge and attitudes-affecting how their knowledge influences their behaviour-and how reflection, creative thinking, and drawing initiate change in participants' underlying attitudes. Recommendations are made to merge a variety of theoretical frameworks into the educational system in order to create curricula that offer a holistic overview and unique insights into sustainability challenges, particularly in specialized areas of the fashion industry.

Sustainable design is fundamentally a subset of good design.The description of good design will eventually include criteria for the creation of a healthy environment and energy efficiency. These goals will be achieved by an emergent paradigm of design practice:integration.At every level design interests will come together to facilitate common goals for the creation of a rewarding present and a healthy future. Interdisciplinary design teams will flourish. Inter-accommodating and fluidly communicating political structures will grow. Coalescing social values and economic forces will propel integrated strategies. Unique and innovative solutions will increasingly become the objective. One eventual outcome of this integrated or sustainable design practice will be the development of buildings that produce more energy than they consume.

Cette thèse contribue à une théorie générale de la conception du projet. S’inscrivant dans une demande marquée par les enjeux du développement durable, l’objectif principal de cette recherche est la contribution d’un modèle théorique de la conception permettant de mieux situer l’utilisation des outils et des normes d’évaluation de la durabilité d’un projet. Les principes fondamentaux de ces instruments normatifs sont analysés selon quatre dimensions : ontologique, méthodologique, épistémologique et téléologique. Les indicateurs de certains effets contre-productifs reliés, en particulier, à la mise en compte de ces normes confirment la nécessité d’une théorie du jugement qualitatif. Notre hypothèse principale prend appui sur le cadre conceptuel offert par la notion de « principe de précaution » dont les premières formulations remontent du début des années 1970, et qui avaient précisément pour objectif de remédier aux défaillances des outils et méthodes d’évaluation scientifique traditionnelles. La thèse est divisée en cinq parties. Commençant par une revue historique des modèles classiques des théories de la conception (design thinking) elle se concentre sur l’évolution des modalités de prise en compte de la durabilité. Dans cette perspective, on constate que les théories de la « conception verte » (green design) datant du début des années 1960 ou encore, les théories de la « conception écologique » (ecological design) datant des années 1970 et 1980, ont finalement convergé avec les récentes théories de la «conception durable» (sustainable design) à partir du début des années 1990. Les différentes approches du « principe de précaution » sont ensuite examinées sous l’angle de la question de la durabilité du projet. Les standards d’évaluation des risques sont comparés aux approches utilisant le principe de précaution, révélant certaines limites lors de la conception d’un projet. Un premier modèle théorique de la conception intégrant les principales dimensions du principe de précaution est ainsi esquissé. Ce modèle propose une vision globale permettant de juger un projet intégrant des principes de développement durable et se présente comme une alternative aux approches traditionnelles d’évaluation des risques, à la fois déterministes et instrumentales. L’hypothèse du principe de précaution est dès lors proposée et examinée dans le contexte spécifique du projet architectural. Cette exploration débute par une présentation de la notion classique de «prudence» telle qu’elle fut historiquement utilisée pour guider le jugement architectural. Qu’en est-il par conséquent des défis présentés par le jugement des projets d’architecture dans la montée en puissance des méthodes d’évaluation standardisées (ex. Leadership Energy and Environmental Design; LEED) ? La thèse propose une réinterprétation de la théorie de la conception telle que proposée par Donald A. Schön comme une façon de prendre en compte les outils d’évaluation tels que LEED. Cet exercice révèle cependant un obstacle épistémologique qui devra être pris en compte dans une reformulation du modèle. En accord avec l’épistémologie constructiviste, un nouveau modèle théorique est alors confronté à l’étude et l’illustration de trois concours d'architecture canadienne contemporains ayant adopté la méthode d'évaluation de la durabilité normalisée par LEED. Une série préliminaire de «tensions» est identifiée dans le processus de la conception et du jugement des projets. Ces tensions sont ensuite catégorisées dans leurs homologues conceptuels, construits à l’intersection du principe de précaution et des théories de la conception. Ces tensions se divisent en quatre catégories : (1) conceptualisation - analogique/logique; (2) incertitude - épistémologique/méthodologique; (3) comparabilité - interprétation/analytique, et (4) proposition - universalité/ pertinence contextuelle. Ces tensions conceptuelles sont considérées comme autant de vecteurs entrant en corrélation avec le modèle théorique qu’elles contribuent à enrichir sans pour autant constituer des validations au sens positiviste du terme. Ces confrontations au réel permettent de mieux définir l’obstacle épistémologique identifié précédemment. Cette thèse met donc en évidence les impacts généralement sous-estimés, des normalisations environnementales sur le processus de conception et de jugement des projets. Elle prend pour exemple, de façon non restrictive, l’examen de concours d'architecture canadiens pour bâtiments publics. La conclusion souligne la nécessité d'une nouvelle forme de « prudence réflexive » ainsi qu’une utilisation plus critique des outils actuels d’évaluation de la durabilité. Elle appelle une instrumentalisation fondée sur l'intégration globale, plutôt que sur l'opposition des approches environnementales.
