An evaluation of the bioclimatic chart for choosing design strategies for a thermostatically-controlled residence in selected climates

Visitsak, Sopa 15 May 2009 (has links)
To be successful in sustainable building design, architects must consider energy efficient design strategies in the early design stage. Unfortunately, many architects still rely on simplified analysis, synthesis techniques, and historical examples. Although, building energy simulations are becoming more common in the design of buildings, architects rarely use simulation in the early design stage. The “Bioclimatic” charts have been used in the early design stage to define potential building design strategies to achieve indoor thermal comfort. Currently, many architects use the Givoni-Milne bioclimatic design chart (Milne and Givoni, 1979), which was developed based on principle reasoning and heuristics. There have been many attempts to develop computerized programs to further the bioclimatic analysis; however, there have been very limited efforts to test and evaluate the design strategies of the chart using simulations of a thermostatically-controlled building. Therefore, the purpose of this research is to promote comfortable buildings that reduce energy use through appropriate building design strategies. The objectives of the research are to develop a more accurate bioclimatic chart for a thermostaticallycontrolled residence by testing and evaluating the Givoni-Milne bioclimatic chart. The analysis is performed with DOE-2.1e program (Winkelmann, 1993) and TMY2 weather data (Marion and Urban, 1995) for several climates. To achieve these objectives, four main tasks were accomplished: 1) investigate the Givoni-Milne Bioclimatic Chart using representative weather data from several climates, 2) analyze and modify the design strategy boundaries using DOE-2 program and TMY2 weather data to simulate the effects of varied conditions of a thermostatically-controlled residence in different climates, 3) compare these new design strategy boundaries to the original Givoni-Milne design strategy boundaries, and 4) develop general guidelines for the new bioclimatic chart. In summary, there were some differences in the results from the Givoni-Milne bioclimatic chart and the DOE-2 simulation results. These results imply that without further modification, the G-M Chart may have only a limited use for a thermostaticallycontrolled residence. Therefore, to improve the usefulness of the bioclimatic chart the new bio-climatic chart for choosing design strategies for a thermostatically-controlled residence in the hot-humid climate of Houston, Texas, was developed. This new bioclimatic chart for a thermostatically-controlled residence will be a useful tool for architects and engineers in the early design stage. Similar versions of the new bioclimatic for other climates could then be developed.

Investigation of a Design Strategy For Liquid Crystals with De Vries-Like Properties

Song, Qingxiang 29 October 2013 (has links)
Ferroelectric liquid crystals (FLCs) have been investigated as the basis for a new type of liquid crystal display because of their fast switching times. In applications the layer contraction at the smectic A-smectic C transition is a severe problem that leads to buckling of the smectic layers and results in zigzag defects that drastically degrade the optical quality of FLC films. To solve this problem, researchers are focusing on a new class of liquid crystals with minimal smectic layer contraction at the SmA-SmC transition which is referred to as ‘de Vries-like’. In the first part of this thesis, we have developed a rational design strategy based on a concept of frustration between two structural elements, one promoting a SmA phase and another promoting a SmC phase. In this chapter, we show that one can further improve ‘de Vries-like’ properties by substituting the 2-phenylpyrimidine core in our first-generation siloxane-terminated mesogens with one stronger SmC-promoting core. We also address the hydrolytic instability of siloxane-terminated mesogens, by substituting the siloxane with a carbosilane end-group. As a result of this study, we found QL6-6 that forms a SmC phase at room temperature with ‘de Vries-like’ properties that are comparable to those of bona fide ‘de Vries-like’ liquid crystals. Next, the dialkoxy 2-phenyl-1,3,4-thiadiazole core which is a very powerful SmC promoting element was investigated. We prepared the analogue of QL6-6, compound QL13-6, which only forms a SmC phase despite having a chloro-terminated alkyl chain. Making a ‘de Vries-like’ liquid crystal without carbosilane terminal side-chain was also attempted, although ultimately unsuccessful. The terminal group effect on the ‘de Vries-like’ properties was also investigated. We prepared a series of mesogens derived from 2-phenylpyridine core with different end-groups to investigate whether the X-group might interact with the core in a bilayer structure. Finally, we inves¬tigated the effect of mixing ’de Vries-like’ liquid crystals with conventional smectic liquid crystals. We show that binary mix¬tures of ‘de Vries-like’ and conventional SmC meso¬gens with a molecular length ratio of 1.34 undergo a SmA-SmC phase transition with a maximum layer contraction ranging from 1.0 to 1.9% depending on the mixture composition. / Thesis (Ph.D, Chemistry) -- Queen's University, 2013-10-29 13:16:29.768

Guidelines for the Design of Augmented Reality Strategy Games

Nilsen, Trond January 2006 (has links)
With augmented reality, we can create interfaces that merge virtual objects and data seamlessly with the real world, potentially improving collaboration and interaction. This technology offers opportunities for games, allowing new designs that merge the diverse social and physical interaction of real world games with rapid interactivity and computing power of digital games. To date, research has primarily focused on issues of technology, interaction design, and nfrastructure; the design of compelling play has received little attention. We play games because they are enjoyable; therefore, in order to create attractive games, we must understand enjoyment. In games, engagement, social interaction, and emotional involvement are among the most common causes. We can design for engagement in play using Csikszentmihalyi's model of 'flow'; for social play by making communication easy, natural, and useful; and emotional involvement by understanding the mechanisms by which games stimulate us. Alongside an understanding of enjoyment, lessons must be drawn from design experience. AR Tankwar is an augmented reality strategy game developed over the course of this thesis, and has been evaluated in the field at a large games convention, and in a detailed comparative study with existing games on tabletop and desktop PC. Evaluations revealed predictable limitations with the technology, but also provided insight into how designers can make best use of the medium. Based on these activities, and existing knowledge of interaction and collaboration in augmented reality, this thesis addresses compelling play in augmented reality by developing a set of design guidelines for augmented reality games, with particular focus on strategy games.

Design i offentlig sektor : En fallstudie med Arbetsförmedlingen

Löfkvist, Sebastian, Sturén, Karolina January 2014 (has links)
Det pågår stora förändringar i världen gällande begreppet design och rapporter har kommit både iSverige och Europa om hur design kan lösa samhällsproblem. Design kan användas som ettverktyg för problemlösning i en arbetsprocess eller som konkurrensfördel i en strategi för attutveckla produkter och tjänster utifrån användarens behov.Forskning finns om hur privata vinstdrivna företag använder design som konkurrensmedel.Syftet med vår studie är att undersöka hur vi med hjälp av design kan skapa en strategi för enorganisation i den offentliga sektorn som kan lösa kommunikationsproblem med fokus påkundtillfredsställelse. Undersökningen syftar till att svara på hur den offentliga sektorn arbetarmed design och hur en designstrategi inom den offentliga sektorn kan se ut, samt om det finnsnågra hinder vid implementering av design.Studien baseras på en kvalitativ metod i form av djupintervjuer, samt en kvantitativenkätundersökning utifrån en fallstudie på Arbetsförmedlingen. Datainsamling av det empiriskamaterialet har gjorts på fallföretaget samt på tre ytterligare tjänsteorienterade organisationer somär finansierade av staten och ett produktorienterat företag. Empirin har analyserats utifrånföretagsekonomiska teorier samt designteorier och den privata sektorn har ställts mot denoffentliga sektorn för att hitta likheter och skillnader dem emellan.Resultatet av studien visar på att design används inom den offentliga sektorn och resultatet visaratt det inte finns några hinder för den offentliga sektorn att jobba med design, men att det iblandkan vara mer svårimplementerat på grund av komplexa organisationer och en målgrupp som ärhela den svenska befolkningen. För att implementera design behöver organisationer i denoffentliga sektorn integrera med sina kunder, förenkla kundresan och inom organisationen arbetamot samma mål och vision där kunden alltid är i fokus. / There are major ongoing changes in the world regarding to the term design and reports havecome both from Sweden and Europe how design can solve social problems. Design can be usedas a tool for problem solving in a work process or as a competitive advantage in a strategy todevelop products and services based on user requirements.The purpose of this study is to examine how we can use design to create a strategy that can solvecommunication problems with a focus on customer satisfaction within an organization workingin the public sector. The study aims to answer how the public sector work with design and how adesign strategy will look like and whether there are any barriers to implement design.The study is based on a qualitative method through interviews and a quantitative survey based ona case study of the Swedish employment authority Arbetsförmedlingen. Data of the empiricalmaterial has been collected from the case company and from three other service-orientatedorganizations funded by the state and a private product-orientated company. The empirical datahas been analyzed with business economic and design theories and the private and the publicsector organizations have been compared to find similarities and differences them between.The results of the study shows that design is used in the public sector but is somewhat difficult toimplement because of its complex organizations and the broad target group containing the entirepopulation of Sweden. To implement design, organizations in the public sector need to integratewith their customers, simplifying the customer journey and internal in the organization worktowards the same goals and vision of where the customer always is in focus.

An investigation of how design managers in organisations in Bahrain manage and evaluate visual communication design for strategic advantage

Hallak, Lilian Issa Anton January 2015 (has links)
The role of visual communication design continues to increase in importance around the world. In Bahrain, organisations are increasingly considering visual communication design as a means of accomplishing organisational goals. The research aims to understand the process by which design managers in organisations in Bahrain manage and evaluate visual communication designs to gain strategic advantage. Even though the management of visual communication design has not yet been recognised as a separate category of design management in Bahrain, its processes and approaches may differ from other management applications. This research opens with a contextual overview of the visual communication design management field, before presenting an understanding of how visual communication design can be utilised as an innovative approach to the strategic structuring organisational thinking. Methods have been developed for investigating how Bahraini client design managers manage visual communication design projects. Observational studies and interviews with client design managers and creative directors have been conducted to obtain an understanding of the visual communication design process, together with evaluation procedures in the Bahraini context. These empirical investigations have led to the development of a conceptual framework that describes the visual communication design management process and the evaluation procedure that is carried out by client design managers in Bahrain. The remainder of this thesis explains the outcomes of each phase of the research. The unique contributions of this study are embodied in a discussion of the findings together with reflections and recommendations for those involved and interested in design management in Bahrain.

Exploring And Implementing Pleasant Touch In The Interface Of Products For Design Purposes: The Case Of A Bang &amp / Olufsen Tv Remote Control

Fennis, Tirza Johanna Maria 01 September 2012 (has links) (PDF)
This thesis proposes a design strategy for pleasant touch. Literature is reviewed on the importance of pleasant touch, existing implementations in products and design for tactility. A lack of competence is found on how to design for pleasant touch in the interface of products: functional pleasant tactility. Therefore, a design vision is created by the author as a designer, on how to design functional pleasant tactility. The envisioned design strategy is then implemented through a study where a Bang &amp / Olufsen TV remote control was used as an example case. The study includes three sequential phases: exploring, designing, and evaluating functional pleasant tactility in the given context. Exploring was done through workshops where design students were asked to touch objects with various material properties. Pleasant movements were performed with the objects, and matching functions were imagined, resulting in &lsquo / actions&rsquo / . Those actions were analyzed to discover three underlying themes of inviting, mastery and logic. In the designing phase, those themes were translated into three corresponding design concepts, and worked out into prototypes. In the evaluating phase, those prototypes were tested with that target group, and the results were used to create a final design concept. The study then concludes with a design strategy that is expected to work for the broader context of industrial design, and recommendations for further research with this strategy and different products or companies are also provided.

Strategies For Creating Inclusive Urban Spaces Along The European Shore Of The Bosphorus

Ozer, Ali 01 June 2008 (has links) (PDF)
The aim of this study is to integrate the basic concepts of landscape urbanism and the principles of universal design approach in order to achieve an inclusive urban surface on the seafront of the Bosphorus. This study may be described as a reinterpretation of the European shore of the Bosphorus, reintroducing the sea to the daily life of stanbul&amp / #8217 / s inhabitants. Landscape urbanism refers to the architecture of an urban surface, a continuous landscape accommodating all kinds of structures and activities to enhance human experience. Universal design is an approach that celebrates human diversity and is often defined as the design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. To achieve its goal, this study focuses on the concept of urban surface and the related design strategies described by Alex Wall, which might help to create inclusive environments. In this way, it attempts to put forward a framework for the implementation of universal design principles to urban scale. It not only evaluates the strategies of landscape urbanism from the perspective offered by the universal design approach, but also attempts to make a contribution to the common brainstorming about shaping the seafront of the Bosphorus.
