How practice size impacts on the implementation and dissemination of post occupancy evaluation

There has been much research on the subject of environmentally sustainable design (ESD), with emerging techniques and technologies improving rapidly and informing sustainability higher education teaching to architects and prospective architects. By examining the success of sustainable designs using post occupancy evaluations, architectural practices might also increase their knowledge of sustainable building practice. Post occupancy evaluations could be useful for improving the designs of future buildings and the design processes that generated them. This paper aims to evaluate these claims by asking: "Do sustainable design practices use the feedback gained from post occupancy evaluations?," "How does the feedback refine the design process?," "How is the information gained in these evaluations absorbed within the firm's design practices?," and, "Does the size of a practice impact on its implementation and
dissemination of POE?" This paper investigates the questions posed above through the questioning of architectural practices that have gained a reputation for environmentally sustainable design by having a strong sustainable design philosophy and/or by being recognised for this by winning a sustainability design award. The interviewed practices will have provided some form of post occupancy evaluation as a service or employed them to add to their own knowledge.

The development of a typology for remote construction projects

Remotely located sites have become more accessible and therefore more valuable and profitable to investors and entrepreneurs. Typically these sites are environmentally sensitive. For the designer, these sites offer a unique challenge conceptually, in terms of the physical and cultural constraints. The built environment research community has yet to seriously take up the challenge of developing theoretical models for the management of the design and construction processes for remotely located projects. Such models would explore efficiency and efficacy management for projects in remote and often hostile areas, in an integrated and sustainable manner. There are varying degrees of remoteness experienced in nearly all construction projects and therefore a clearer definition of the characteristics of remote sites is required. Towards this definition, a typology is initiated for the concept of remotely located construction projects related to environmental sustainability and the management of the design process. The characteristics of the typology are drawn from a selected literature review of the fields of design management and environmental sustainability, and from an exploratory investigation of two case studies.

Developing an ‘as performing’ building assessment

The building profession is increasingly becoming more demanding with respect to building environmental performance. Intentions are to provide best practices into our buildings. In part, this is a response due to the Australian government and other independent organisations that have developed policy on rating tools and performance ranking measures, all with the intention of accomplishing environmentally sustainable buildings.

With rating systems endorsing innovative environmental design solutions, it could be asked: Are our buildings really operating as rated? Do we know whether our designs are in compliance with what was calculated or simulated? Is there a feedback loop informing the design process on successes or failures in our designs or mechanical services?

While ratings continue to focus on ‘by design’ or ‘as built’ rewards, few tools acknowledge perhaps the more crucial bottom line: ‘as performing’. With the exception of an AGBR (Australian Green Building Rating) scheme on actual annual energy consumption, there appears to be no ‘as performing’ assessment. Furthermore, practically every building is a prototype (a one-off) and requires commissioning, programming and scheduling of its services. It would certainly appear that as stakeholders (the procurers, owners, facilities managers and users) of the newly built environment, that what we really want to know is actual on-site confirmation of performance. It is the objective of the Mobile Architecture and Built Environment Laboratory (MABEL), to provide such a service.

Carriers and components

Parametric modelling is a powerful means of geometric control. Within the field of architecture, there are wide ranging possibilities in form generation, self analysing structural systems and performative building facades. This thesis has investigated the potential of parametric modelling as a design tool, specifically in the exploration of architectural surfaces.

Physical prototypes in cross-functional team collaboration : a study of the Model-T2 concept car project

Virtual and physical prototypes play a significant role in the design of artifacts. This is particularly true in cross-functional team collaboration, where diverse disciplines come together to contribute to the concept, design and development of an artifact. While the role of prototyping in design and cross-functional collaboration has been widely studied independently, little is known of the role that physical prototypes play during cross-functional team collaboration. This paper reports on a study of virtual and physical prototyping strategies used by a cross-functional team comprising engineers and designers working on a concept car project. The paper provides a background of the collaborative design process and details the role of physical prototyping methods during the design of the concept car.

A parametric approach to 3D massing and density modelling

This paper addresses the current void between social agendas, environmental criteria and design methodology in urban planning through the implementation of new computational systems. It considers the application of digital design tools such as GIS and parametric systems towards more efficient and effective design solutions. The digital design methods have been developed and tested within Grimshaw Architects Design Technology Group on both Australian and international urban development projects. A methodology for the use of parametric design for urban design development is suggested for defining, simplifying and categorising planning and design strategies. The following tools are a means of generating urban design concepts as digital forms in order to better inform the designer during the design process.

Thermal comfort in outdoor places a multicultural perception

The outdoor places are receiving more importance being contributing in the social cohesion and sustainability within societies. Providing comfortable sustainable urban places is an important factor affecting their success especially in multicultural areas where climatic conditions are perceived differently according to the diversity of users. Different design elements such as design form proved to be able to improve the outdoor thermal comfort. However, the integration of the climate dimension in the design process of outdoor places is lacking due to insufficient interdisciplinary work between urban climatology, and urban design. The main aim of the research is to examine the influence of cultural and climatic background on users’ thermal sensation and comfort within the same context. The methodology of the research is provided through quantitative analysis of a case study in Melbourne, Australia as one of the global cities characterized by the diversity and plurality of its population. The case study approach is adopted in order to examine the users’ thermal comfort within its contextual variables. Multiple sources of evidence such as climate measurements, questionnaires and observations are used to ensure the validity of results. The findings are to contribute to the quality and equality of design for outdoor urban places.

Effect of thermal adaptation on outdoor comfort perception

Thermal comfort in outdoor places has proven to have a strong relationship with their users’ attendance and behaviour [1]. Creating comfortable places is therefore to be considered a crucial part of the design process, as taking it into consideration help increasing the social integration between people and therefore fosters sustainability within cities [2]. With the increasing number of migrants within global cities, a new challenge has been facing thermal comfort studies. This challenge is related to the different cultural and climatic origins of those migrants and how they can adapt to the new climatic conditions they are to move in. This paper aims to explore the impact of thermal comfort adaptation on users’ thermal perception in multicultural cities. Consequently, a quantitative field study is applied in Melbourne city, Australia in order to investigate peoples’ outdoor thermal comfort. The analyses were based upon the measurement of climatic parameters that were monitored simultaneously with a questionnaire to determine users’ thermal comfort perception in relation to their time spent in the city. The findings of thermal comfort investigations could be applied into improving the quality of urban areas within global cities and therefore promote the integration within individuals in those societies.

It can be quite difficult to have your creativity on tap : balancing client expectations and artistic practice in the tattoo industry

Tattoo artists work in a commission structure. Their artistic practice, possibly more than in any other creative career, requires the complete approval of the client prior to the creation of the final work. An unsatisfactory tattoo cannot be on-sold, discarded or easily replaced. Rarely can a tattooer practice their art without external participation. Therefore, tattoo artists come up with a number of strategies to manage their client base to ensure that the art they are asked to create satisfies both the client and their own artistic skills and preferences. Drawing on phenomenological research conducted for my PhD investigating artistic persona, this paper will explore the strategies tattoo artists use to construct their portfolios, manage the tattoo consultation and design process, and develop their own artistic skills, in order to build a successful and rewarding career in the tattoo industry.

Implementation of a quality care management system for patients with arthritis of the hip and knee

The Orthopaedic Unit of the Repatriation General Hospital (RGH) in Adelaide, South Australia has implemented a quality care management system for patients with arthritis of the hip and knee. The system not only optimises conservative management but ensures that joint replacement surgery is undertaken in an appropriate and timely manner. This new service model addresses identified barriers to service access and provides a comprehensive, coordinated strategy for patient management. Over 4 years the model has reduced waiting times for initial outpatient assessment from 8 to 3 months and surgery from 18 to 8 months, while decreasing length of stay from 6.3 to 5.3 days for hips and 5.8 to 5.3 days for knees. The service reforms have been accompanied by positive feedback from patients and referring general practitioners in relation to the improved coordination of care and enhanced efficiency in service delivery.

What is known about the topic? Several important initiatives both overseas and within Australia have contributed significantly to the development of this model of care. These include the UK National Health Service ‘18 weeks’ Project, the Western Canada Waiting List Project, the New Zealand priority criteria project, the Queensland Health Orthopaedic Physiotherapy Screening Clinic, and most importantly the Melbourne Health–University of Melbourne Orthopaedic Waiting List Project where a wide range of models were explored across Victorian hospitals from 2005 and the Multi-Attribute Prioritisation Tool (MAPT) was developed, validated and tested. This project became the Osteoarthritis Hip and Knee Service (OAHKS) and was operationalised in the Victorian healthcare system from 2012. These initiatives examined and addressed various aspects of management systems for patients with arthritis of the hip and knee in their particular setting.

What does this paper add? The development of this system is an extension of what is already known and is the first to encompass a comprehensive and coordinated strategy across all stages of the care management pathway for this patient group. Their management extends from the initial referral to development and implementation of a management plan, including surgery if assessed as necessary and organisation of long-term post operative follow up as required. By detailing the elements, key processes and measurable outcomes of the service redesign this paper provides a model for other institutions to implement a similar initiative.

What are the implications for practitioners? An important aspect of the design process was practitioner acceptance and engagement and the ability to improve their capacity to deliver services within an efficient and effective model. Intrinsic to the model’s development was assessment of practitioner satisfaction. Data obtained including practitioner surveys indicated an increased level of both satisfaction with the redesigned management service, and confidence in it to deliver its intended improvements.

Reading, writing, crafting – Innovations in first year tertiary writing pedagogy

This paper will outline some of the rationale behind, and strategies contributing to, curriculum revision in first-year creative writing at Deakin University in 2012 – delivered in that year and currently running in 2013. The process aimed to produce two consecutive offerings, with distinct but strategically scaffolded preoccupations. This paper deals with the first of these. The design process for this offering, named ‘Writing Craft’, involved addressing two central concerns: (a) the need to unhook the initial encounter with tertiary creative writing pedagogy from a preoccupation with ‘genres’ or the ‘forms’ of creative writing (such as prose fiction, creative nonfiction, script, poetry, and so on) and instead to reorient efforts towards establishing an engagement with craft per se; (b) to address a perceived impoverishment in the range of texts to which students had been exposed prior to commencing study – in other words, to emphasise the practice of reading to facilitate the practice of writing. The curriculum design also involved reimagining assessment, noting the ‘messages about making’ sent to students via the framing of tasks and rubrics. Aiming instead to deemphasise the role of inspiration and ‘work arriving fully formed’, it sought to offer assessment that provided clear – and bounded – prompts for incidents of making and the practice of craft, as well as to provoke conversation with a broad range of texts as a way of courting intertextual inspiration and aesthetic formation.

RF techniques for lowering the actuation voltage of RF MEMS shunt capacitor switch for C-K band

Increasing the capacitance ratio in RF MEMS shunt capacitive switch will increase its RF performance but also raise its actuation voltage. To improve the RF performance of the switch without increasing its capacitance ratio, this paper explores two methods: reducing the LC resonance from the mm-wave into the X-band by using an inductive bridge, and using two short high impedance transmission lines at both ends of the CPW line. Accordingly, this paper presents the design and simulation of an electro-static low actuation voltage and a very high isolation multipurpose switch with a very large bandwidth. The simulation results are presented and discussed.

Research in practice : an exercise in generative urban massing

The following paper explores practice based research as a means of identifying issues within current urban design methods. It considers the application of parametric systems as a means of addressing these issues. These systems are developed and tested across both Australian and international urban design projects within Grimshaw Architects. A methodology is proposed for the development and application of these parametric tools across multiple scales of design resolution. It reports on the application of a set of parametric urban scale massing tools in real world design projects. This exploration is carried out in distinct phases of design defined by the scale of resolution. The phasing allows for discrete problems to be addressed more effectively at different stages of the design process while still encouraging a seamless, bi directional workflow through a digital master model.

RF rectifiers for EM power harvesting in a deep brain stimulating device

A passive deep brain stimulation (DBS) device can be equipped with a rectenna, consisting of an antenna and a rectifier, to harvest energy from electromagnetic fields for its operation. This paper presents optimization of radio frequency rectifier circuits for wireless energy harvesting in a passive head-mountable DBS device. The aim is to achieve a compact size, high conversion efficiency, and high output voltage rectifier. Four different rectifiers based on the Delon doubler, Greinacher voltage tripler, Delon voltage quadrupler, and 2-stage charge pumped architectures are designed, simulated, fabricated, and evaluated. The design and simulation are conducted using Agilent Genesys at operating frequency of 915 MHz. A dielectric substrate of FR-4 with thickness of 1.6 mm, and surface mount devices (SMD) components are used to fabricate the designed rectifiers. The performance of the fabricated rectifiers is evaluated using a 915 MHz radio frequency (RF) energy source. The maximum measured conversion efficiency of the Delon doubler, Greinacher tripler, Delon quadrupler, and 2-stage charge pumped rectifiers are 78, 75, 73, and 76 % at -5 dBm input power and for load resistances of 5-15 kΩ. The conversion efficiency of the rectifiers decreases significantly with the increase in the input power level. The Delon doubler rectifier provides the highest efficiency at both -5 and 5 dBm input power levels, whereas the Delon quadrupler rectifier gives the lowest efficiency for the same inputs. By considering both efficiency and DC output voltage, the charge pump rectifier outperforms the other three rectifiers. Accordingly, the optimised 2-stage charge pumped rectifier is used together with an antenna to harvest energy in our DBS device.

A practical functional observer scheme for interconnected time-delay systems

This paper proposes a partially distributed functional observer scheme for a class of interconnected linear systems with very strong non-instantaneous subsystems interaction and with time delays in the local states and in the transmission of output information from the remote subsystems. A set of easily verifiable existence conditions is established and upon its satisfaction, simple distributed observers are designed using a straightforward design procedure. Simulation results of a numerical example are given to substantiate the feasibility of the approach.
