Design and management of sustainable built environments

The United Nation Intergovernmental Panel on Climate Change (IPCC) makes it clear that climate change is due to human activities and it recognises buildings as a distinct sector among the seven analysed in its 2007 Fourth Assessment Report. Global concerns have escalated regarding carbon emissions and sustainability in the built environment. The built environment is a human-made setting to accommodate human activities, including building and transport, which covers an interdisciplinary field addressing design, construction, operation and management. Specifically, Sustainable Buildings are expected to achieve high performance throughout the life-cycle of siting, design, construction, operation, maintenance and demolition, in the following areas: • energy and resource efficiency; • cost effectiveness; • minimisation of emissions that negatively impact global warming, indoor air quality and acid rain; • minimisation of waste discharges; and • maximisation of fulfilling the requirements of occupants’ health and wellbeing. Professionals in the built environment sector, for example, urban planners, architects, building scientists, engineers, facilities managers, performance assessors and policy makers, will play a significant role in delivering a sustainable built environment. Delivering a sustainable built environment needs an integrated approach and so it is essential for built environment professionals to have interdisciplinary knowledge in building design and management . Building and urban designers need to have a good understanding of the planning, design and management of the buildings in terms of low carbon and energy efficiency. There are a limited number of traditional engineers who know how to design environmental systems (services engineer) in great detail. Yet there is a very large market for technologists with multi-disciplinary skills who are able to identify the need for, envision and manage the deployment of a wide range of sustainable technologies, both passive (architectural) and active (engineering system),, and select the appropriate approach. Employers seek applicants with skills in analysis, decision-making/assessment, computer simulation and project implementation. An integrated approach is expected in practice, which encourages built environment professionals to think ‘out of the box’ and learn to analyse real problems using the most relevant approach, irrespective of discipline. The Design and Management of Sustainable Built Environment book aims to produce readers able to apply fundamental scientific research to solve real-world problems in the general area of sustainability in the built environment. The book contains twenty chapters covering climate change and sustainability, urban design and assessment (planning, travel systems, urban environment), urban management (drainage and waste), buildings (indoor environment, architectural design and renewable energy), simulation techniques (energy and airflow), management (end-user behaviour, facilities and information), assessment (materials and tools), procurement, and cases studies ( BRE Science Park). Chapters one and two present general global issues of climate change and sustainability in the built environment. Chapter one illustrates that applying the concepts of sustainability to the urban environment (buildings, infrastructure, transport) raises some key issues for tackling climate change, resource depletion and energy supply. Buildings, and the way we operate them, play a vital role in tackling global greenhouse gas emissions. Holistic thinking and an integrated approach in delivering a sustainable built environment is highlighted. Chapter two demonstrates the important role that buildings (their services and appliances) and building energy policies play in this area. Substantial investment is required to implement such policies, much of which will earn a good return. Chapters three and four discuss urban planning and transport. Chapter three stresses the importance of using modelling techniques at the early stage for strategic master-planning of a new development and a retrofit programme. A general framework for sustainable urban-scale master planning is introduced. This chapter also addressed the needs for the development of a more holistic and pragmatic view of how the built environment performs, , in order to produce tools to help design for a higher level of sustainability and, in particular, how people plan, design and use it. Chapter four discusses microcirculation, which is an emerging and challenging area which relates to changing travel behaviour in the quest for urban sustainability. The chapter outlines the main drivers for travel behaviour and choices, the workings of the transport system and its interaction with urban land use. It also covers the new approach to managing urban traffic to maximise economic, social and environmental benefits. Chapters five and six present topics related to urban microclimates including thermal and acoustic issues. Chapter five discusses urban microclimates and urban heat island, as well as the interrelationship of urban design (urban forms and textures) with energy consumption and urban thermal comfort. It introduces models that can be used to analyse microclimates for a careful and considered approach for planning sustainable cities. Chapter six discusses urban acoustics, focusing on urban noise evaluation and mitigation. Various prediction and simulation methods for sound propagation in micro-scale urban areas, as well as techniques for large scale urban noise-mapping, are presented. Chapters seven and eight discuss urban drainage and waste management. The growing demand for housing and commercial developments in the 21st century, as well as the environmental pressure caused by climate change, has increased the focus on sustainable urban drainage systems (SUDS). Chapter seven discusses the SUDS concept which is an integrated approach to surface water management. It takes into consideration quality, quantity and amenity aspects to provide a more pleasant habitat for people as well as increasing the biodiversity value of the local environment. Chapter eight discusses the main issues in urban waste management. It points out that population increases, land use pressures, technical and socio-economic influences have become inextricably interwoven and how ensuring a safe means of dealing with humanity’s waste becomes more challenging. Sustainable building design needs to consider healthy indoor environments, minimising energy for heating, cooling and lighting, and maximising the utilisation of renewable energy. Chapter nine considers how people respond to the physical environment and how that is used in the design of indoor environments. It considers environmental components such as thermal, acoustic, visual, air quality and vibration and their interaction and integration. Chapter ten introduces the concept of passive building design and its relevant strategies, including passive solar heating, shading, natural ventilation, daylighting and thermal mass, in order to minimise heating and cooling load as well as energy consumption for artificial lighting. Chapter eleven discusses the growing importance of integrating Renewable Energy Technologies (RETs) into buildings, the range of technologies currently available and what to consider during technology selection processes in order to minimise carbon emissions from burning fossil fuels. The chapter draws to a close by highlighting the issues concerning system design and the need for careful integration and management of RETs once installed; and for home owners and operators to understand the characteristics of the technology in their building. Computer simulation tools play a significant role in sustainable building design because, as the modern built environment design (building and systems) becomes more complex, it requires tools to assist in the design process. Chapter twelve gives an overview of the primary benefits and users of simulation programs, the role of simulation in the construction process and examines the validity and interpretation of simulation results. Chapter thirteen particularly focuses on the Computational Fluid Dynamics (CFD) simulation method used for optimisation and performance assessment of technologies and solutions for sustainable building design and its application through a series of cases studies. People and building performance are intimately linked. A better understanding of occupants’ interaction with the indoor environment is essential to building energy and facilities management. Chapter fourteen focuses on the issue of occupant behaviour; principally, its impact, and the influence of building performance on them. Chapter fifteen explores the discipline of facilities management and the contribution that this emerging profession makes to securing sustainable building performance. The chapter highlights a much greater diversity of opportunities in sustainable building design that extends well into the operational life. Chapter sixteen reviews the concepts of modelling information flows and the use of Building Information Modelling (BIM), describing these techniques and how these aspects of information management can help drive sustainability. An explanation is offered concerning why information management is the key to ‘life-cycle’ thinking in sustainable building and construction. Measurement of building performance and sustainability is a key issue in delivering a sustainable built environment. Chapter seventeen identifies the means by which construction materials can be evaluated with respect to their sustainability. It identifies the key issues that impact the sustainability of construction materials and the methodologies commonly used to assess them. Chapter eighteen focuses on the topics of green building assessment, green building materials, sustainable construction and operation. Commonly-used assessment tools such as BRE Environmental Assessment Method (BREEAM), Leadership in Energy and Environmental Design ( LEED) and others are introduced. Chapter nineteen discusses sustainable procurement which is one of the areas to have naturally emerged from the overall sustainable development agenda. It aims to ensure that current use of resources does not compromise the ability of future generations to meet their own needs. Chapter twenty is a best-practice exemplar - the BRE Innovation Park which features a number of demonstration buildings that have been built to the UK Government’s Code for Sustainable Homes. It showcases the very latest innovative methods of construction, and cutting edge technology for sustainable buildings. In summary, Design and Management of Sustainable Built Environment book is the result of co-operation and dedication of individual chapter authors. We hope readers benefit from gaining a broad interdisciplinary knowledge of design and management in the built environment in the context of sustainability. We believe that the knowledge and insights of our academics and professional colleagues from different institutions and disciplines illuminate a way of delivering sustainable built environment through holistic integrated design and management approaches. Last, but not least, I would like to take this opportunity to thank all the chapter authors for their contribution. I would like to thank David Lim for his assistance in the editorial work and proofreading.

Supporting visual assessment of food and nutrient intake in a clinical care setting

Monitoring nutritional intake is an important aspect of the care of older people, particularly for those at risk of malnutrition. Current practice for monitoring food intake relies on hand written food charts that have several inadequacies. We describe the design and validation of a tool for computer-assisted visual assessment of patient food and nutrient intake. To estimate food consumption, the application compares the pixels the user rubbed out against predefined graphical masks. Weight of food consumed is calculated as a percentage of pixels rubbed out against pixels in the mask. Results suggest that the application may be a useful tool for the conservative assessment of nutritional intake in hospitals.

Using the Technology Acceptance Model to explore community dwelling older adults’ perceptions of a 3D interior design application to facilitate pre-discharge home adaptations

Background In the UK occupational therapy pre-discharge home visits are routinely carried out as a means of facilitating safe transfer from the hospital to home. Whilst they are an integral part of practice, there is little evidence to demonstrate they have a positive outcome on the discharge process. Current issues for patients are around the speed of home visits and the lack of shared decision making in the process, resulting in less than 50 % of the specialist equipment installed actually being used by patients on follow-up. To improve practice there is an urgent need to examine other ways of conducting home visits to facilitate safe discharge. We believe that Computerised 3D Interior Design Applications (CIDAs) could be a means to support more efficient, effective and collaborative practice. A previous study explored practitioners perceptions of using CIDAs; however it is important to ascertain older adult’s views about the usability of technology and to compare findings. This study explores the perceptions of community dwelling older adults with regards to adopting and using CIDAs as an assistive tool for the home adaptations process. Methods Ten community dwelling older adults participated in individual interactive task-focused usability sessions with a customised CIDA, utilising the think-aloud protocol and individual semi-structured interviews. Template analysis was used to carry out both deductive and inductive analysis of the think-aloud and interview data. Initially, a deductive stance was adopted, using the three pre-determined high-level themes of the technology acceptance model (TAM): Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Actual Use (AU). Inductive template analysis was then carried out on the data within these themes, from which a number of sub-thmes emerged. Results Regarding PU, participants believed CIDAs served as a useful visual tool and saw clear potential to facilitate shared understanding and partnership in care delivery. For PEOU, participants were able to create 3D home environments however a number of usability issues must still be addressed. The AU theme revealed the most likely usage scenario would be collaborative involving both patient and practitioner, as many participants did not feel confident or see sufficient value in using the application autonomously. Conclusions This research found that older adults perceived that CIDAs were likely to serve as a valuable tool which facilitates and enhances levels of patient/practitioner collaboration and empowerment. Older adults also suggested a redesign of the interface so that less sophisticated dexterity and motor functions are required. However, older adults were not confident, or did not see sufficient value in using the application autonomously. Future research is needed to further customise the CIDA software, in line with the outcomes of this study, and to explore the potential of collaborative application patient/practitioner-based deployment.

Grafisk profilering för butiksmiljö : Creating a visual identity for a store

A new visual identity for the ski store Alpingaraget in Stockholm has been proposed as the result of this thesis. Theproposal includes a new logotype, various printed matters, design planning of the store, interior design, signs and otherapplications.The theory section is within the field of graphic profiling and with some focus on profiling in stores.A clear visual identity is important for a company because what the company communicates internally and externallyshould be kept as consistent as possible. This is especially important nowadays when more and more similar products andstores are available. This means that the visual identity becomes part of the competition with other products and stores.The base elements in a visual identity are logotype, colors and typograpy. Using these elements according to rules andtemplates makes a consistent visual profile.

Corporate identity through graphic design

The degree project has been implemented abroad in Brisbane, Australia. A literature study has beenperformed parallel to the practical work within the subject »Corporate identity through graphicaldesign«. In this study deeper research has been made concerning the establishment and manifestationof a corporate identity and its program. The knowledge given from this study has been put into practicethrough two larger projects.The first project was carried out at De Pasquale, advertising agency in Brisbane, where a corporateidentity program was designed for a new company. The company is a fitness centre, called KnockoutFitness, which specializes in different types of boxing training sessions such as Boxing, Thai Bow andBoxercise but also Aqua aerobics. They needed a full corporate identity program including a logotype,business card, letter paper-paper and address labels.The second project was carried out at Queensland University of Technology in Brisbane. A promotioncampaign was designed for the Department of Visual Arts, which included two information folders andone advertisement. The purpose of the campaign was to promote both the undergraduate and postgraduatecourses offered within the department.

Acoustic Design in Urban Development : analysis of urban soundscapes and acoustic ecology research in New York City

The world is urbanizing rapidly with more than half of the global population now living in cities. Improving urban environments for the well-being of the increasing number of urban citizens is becoming one of the most important challenges of the 21st century. Even though it is common that city planners have visions of a ’good urban milieu’, those visions are concerning visual aesthetics or practical matters. The qualitative perspective of sound, such as sonic diversity and acoustic ecology are neglected aspects in architectural design. Urban planners and politicians are therefore largely unaware of the importance of sounds for the intrinsic quality of a place. Whenever environmental acoustics is on the agenda, the topic is noise abatement or noise legislation – a quantitative attenuation of sounds. Some architects may involve acoustical aspects in their work but sound design or acoustic design has yet to develop to a distinct discipline and be incorporated in urban planning.My aim was to investigate to what extent the urban soundscape is likely to improve if modern architectural techniques merge with principles of acoustics. This is an important, yet unexplored, research area. My study explores and analyses the acoustical aspects in urban development and includes interviews with practitioners in the field of urban acoustics, situated in New York City. My conclusion is that to achieve a better understanding of the human living conditions in mega-cities, there is a need to include sonic components into the holistic sense of urban development.

Manual and electroacupuncture for labour pain : study design of a longitudinal randomized controlled trial

Introduction. Results from previous studies on acupuncture for labour pain are contradictory and lack important information on methodology. However, studies indicate that acupuncture has a positive effect on women's experiences of labour pain. The aim of the present study was to evaluate the efficacy of two different acupuncture stimulations, manual or electrical stimulation, compared with standard care in the relief of labour pain as the primary outcome. This paper will present in-depth information on the design of the study, following the CONSORT and STRICTA recommendations. Methods. The study was designed as a randomized controlled trial based on western medical theories. Nulliparous women with normal pregnancies admitted to the delivery ward after a spontaneous onset of labour were randomly allocated into one of three groups: manual acupuncture, electroacupuncture, or standard care. Sample size calculation gave 101 women in each group, including a total of 303 women. A Visual Analogue Scale was used for assessing pain every 30 minutes for five hours and thereafter every hour until birth. Questionnaires were distributed before treatment, directly after the birth, and at one day and two months postpartum. Blood samples were collected before and after the first treatment. This trial is registered at ClinicalTrials.gov: NCT01197950.

Ferramenta visual para especificação de hiperdocumentos, segundo o método OOHDM

O desenvolvimento de artefatos de software é um processo de engenharia, como todo processo de engenharia, envolve uma série de etapas que devem ser conduzidas através de uma metodologia apropriada. Para que um determinado software alcance seus objetivos, as características conceituais e arquiteturais devem ser bem definidas antes da implementação. Aplicações baseadas em hiperdocumentos possuem uma característica específica que é a definição de seus aspectos navegacionais. A navegação é uma etapa crítica no processo de definição de softwares baseados em hiperdocumentos, pois ela conduz o usuário durante uma sessão de visita ao conteúdo de um site. Uma falha no processo de especificação da navegação causa uma perda de contexto, desorientando o usuário no espaço da aplicação. Existem diversas metodologias para o tratamento das características de navegação de aplicações baseadas em hiperdocumentos. As principais metodologias encontradas na literatura foram estudadas e analisadas neste trabalho. Foi realizada uma análise comparativa entre as metodologias, traçando suas abordagens e etapas. O estudo das abordagens de especificação de hiperdocumentos foi uma etapa preliminar servindo como base de estudo para o objetivo deste trabalho. O foco é a construção de uma ferramenta gráfica de especificação conceitual de hiperdocumentos, segundo uma metodologia de modelagem de software baseado em hiperdocumentos. O método adotado foi o OOHDM (Object-Oriented Hypermedia Design Model), por cercar todas as etapas de um processo de desenvolvimento de aplicações, com uma atenção particular à navegação. A ferramenta implementa uma interface gráfica onde o usuário poderá modelar a aplicação através da criação de modelos. O processo de especificação compreende três modelos: modelagem conceitual, modelagem navegacional e de interface. As características da aplicação são definidas em um processo incremental, que começa na definição conceitual e finaliza nas características de interface. A ferramenta gera um protótipo da aplicação em XML. Para a apresentação das páginas em um navegador Web, utilizou-se XSLT para a conversão das informações no formato XML para HTML. Os modelos criados através das etapas de especificação abstrata da aplicação são exportados em OOHDM-ML. Um estudo de caso foi implementado para validação da ferramenta. Como principal contribuição deste trabalho, pode-se citar a construção de um ambiente gráfico de especificação abstrata de hiperdocumentos e um ambiente de implementação de protótipos e exportação de modelos. Com isso, pretende-se orientar, conduzir e disciplinar o trabalho do usuário durante o processo de especificação de aplicações.

Estudo das variáveis de rugosidade, dureza e condutividade térmica aplicado à percepção tátil em design de produto

Este trabalho apresenta um estudo sobre a relação existente entre as variáveis de rugosidade, dureza e condutividade térmica de alguns materiais utilizados em design de produto e a percepção tátil. Inicialmente, foram realizadas pesquisas de descritores subjetivos que os usuários relacionavam com o ato de tocar. A partir destes resultados, foram identificadas características superficiais dos materiais que estavam ligadas a estes descritores. Foi possível então, desenvolver amostras em diferentes materiais (cerâmicos, poliméricos, metálicos e naturais), para serem testadas em ensaios diversos. Os primeiros testes realizados, permitiam a visualização das amostras. Posteriormente, foram realizados ensaios de forma que os entrevistados não podiam visualizar as amostras. Desta forma, somente a percepção tátil era testada sem influência dos demais órgãos dos sentidos. Nestes testes, os entrevistados verificavam entre as variáveis abordadas no trabalho (rugosidade, dureza e condutividade térmica), se haviam diferenças entre as amostras e ordenavam de maior à menor conforme o que era percebido. Com base nas respostas obtidas, e também nos valores atribuídos às amostras para as variáveis já relacionadas anteriormente, foi possível verificar limiares de percepção e também, a relação existente entre o que é percebido e os valores atribuídos às respectivas variáveis tecnológicas. Os resultados obtidos indicam que a percepção de diferentes texturas, foi mais facilmente detectada do que diferenças de condutividade térmica e principalmente de dureza. A preferência por texturas menos rugosas foi detectada em grande parte das respostas obtidas Da mesma forma, pode-se dizer que a temperatura ambiente de realização dos testes para condutividade térmica, teve influência direta nas respostas obtidas. Para os ensaios aplicados, não houve diferença grande entre respostas de adultos e de crianças e também entre crianças com deficiência visual e crianças sem deficiência. A investigação da percepção tátil, e posteriormente a relação que se pode fazer desta com algumas das propriedades dos materiais, contribui tanto na seleção de materiais para projeto de produtos, como para seleção de processos de fabricação. Sendo assim, este estudo pode servir como mais uma ferramenta no processo de criação, considerando assim os futuros usuários. Desta maneira, o vínculo entre o usuário e o produto torna-se mais forte, já que este atende às necessidades e também considera a percepção do usuário em relação aos materiais utilizados, podendo, inclusive, evitar um descarte rápido contribuindo para aumentar a sustentabilidade. Além disto, este estudo permite também que a produção nas indústrias de determinados segmentos (têxtil, brinquedos, utensílios, etc.) possa ser orientada de forma que considere limiares de percepção, evitando assim investimentos desnecessários em processos de produção que resultariam em mudanças que podem não ser percebidas pelos usuários. Em suma, os resultados obtidos neste estudo, podem ser utilizados em diversas áreas da Engenharia e do Design, agregando a estas uma ferramenta na orientação de projetos.

Um sistema informacional e perceptivo de seleção de materiais com enfoque no design de calçados

O presente trabalho decorre da importânciada Seleção dos Materiais no Design de produtos como um fator tecnológico para a inovação e minimização de falhas de projetos. Assim, a investigação dos fatores importantes para a determinação dos seus requisitos ou objetivos torna-se primordial para se estabelecer uma seleção adequada na proposta, buscando determinar o grau de satisfação do consumidor através do atendimento às variáveis objetivas e subjetivas dos projetos que foram abordadas neste estudo. Em função do grande número de diferentes materiais existentes, este processo apresenta-se de forma complexa. Desse modo, a investigação realizada, sobre os diferentes meios de interpretação dos materiais, direcionou a pesquisa à abordagem do estudo de caso de uma Materioteca, referenciandoum sistema de seleção de materiais, onde a inclusão das variáveis subjetivas no processo vem determinar vantagens, estimulando a percepção tátil e visual do projetista. A grande participação conjunta e simultânea do Design e da Engenharia, buscando atrelar aspectos estéticos e subjetivos às viabilidades técnicas e produtivas, foram identificadas neste sistema, onde a avaliação da forma, da textura, da funcionalidade, da durabilidade, da sustentabilidade, do conceito, entre outros itens, apontam para a obtenção de novos requisitos com elevado grau de prioridade. Assim, pode-se dizer que o reconhecimento dos valores subjetivos (percepção) dos materiais, uma vez adaptados em projetos, agregam maior valor ao produto resultante, instigando o Designer a cada vez mais confrontar novos quesitos no momento da projetação, reforçando a potencialidade conceitual expressiva contida nos objetos de consumo, como, por exemplo, a marca do produto e o status social que este possa agregar, baseados na forma de pensar e na maneira de viver do consumidor, em função de suas percepções, com base nos principais órgãos dos sentidos. Em suma, os resultados obtidos neste estudo podem ser utilizados em diversas áreas do Design e da Engenharia, agregando-secomo uma ferramenta na orientação de projetos do setor calçadista.

Produção e reprodução do design como conhecimento: (indicações para uma compreensão do discurso do design)

A atividade básica do designer é a concepçao, em parte ou totalmente, de uma mercadoria industrializada que envolva manuseio e/ou percepção visual por parte do homem. Como outros profissionais contemporâneos, o designer é um técnico nascido com a indústria, e se adequa a ela em níveis: dois - a) há uma funcionalidade entre indústria e design como conhecimento técnico; b) e também há uma funcionalidade entre a superioridade que o designer sente, devida a seu conhecimento acadêmico, e a hierarquia disciplinar da organização da produção capitalista. Exprimindo esta ligação orgânica com o capitalismo industrial, o discurso que apresenta o conhecimento que define o design não é apenas um recurso prático para a sinalização da prática profissional. Os seus termos técnicos, supostamente só técnicos, convêem à organização social da produção capitalista, reforçando a ideologia que esconde a dominação do capital.
