Changing the Architectural Profession - Evidence-Based Design, the New Role of the User and a Process-Based Approach

The construction industry is characterised by ever-changing projects that constantly involve new clients, teams and people. This results in the need to build up new sets of relationships each time. Within these relationships the perspective of the users of space is mostly neglected, partly due to the ephemeral nature of the industry, but partly also because of the character and culture of the architectural profession. In contrast, this paper argues that the architectural profession needs to make a double turn: firstly, the needs and wishes of the user need to be in the centre of the architectural business. Secondly, the whole industry may change from a project-centred one into a process-based one where the process of finding out what the client needs, of engaging the users, proposing a design solution, managing the project, and evaluating its use and appropriation in the end in order to learn from it, is nearly as important as aesthetics, form and function. This involves a lot more intelligence and research about cultures and characteristics of the client, may it be a private person, a city council or a corporation, hence architectural and organisational research may play a new role in the architectural professional culture

Improved performance of motor-drive systems by SAW shaft torque feedback

The paper describes the application of a non-contact, high bandwidth, low cost, SAW-based torque measuring system for improving the dynamic performance of industrial process motor-drive systems. Background to the SAW technology and its motor integration is discussed and a resonance ratio control (RRC) technique for the coordinated motion control of multi-inertia mechanical systems, based on the measurement of shaft torque via a SAW-based torque sensor is proposed. Furthermore, a new controller structure, RRC plus disturbance feedback is proposed, which enables the controller to be designed to independently satisfy tracking and regulation performance. A tuning method for the RRC structure is given based on the ITAE index, normalized as a function of the mechanical parameters enabling a direct performance comparison between a basic proportional and integral (PI) controller. The use of a reduced-order state observer is presented to provide a dynamic estimate of the load-side disturbance torque for a multi-inertia mechanical system, with an appraisal of the composite closed-loop dynamics. The control structures are experimentally validated and demonstrate significant improvement in dynamic tracking performance, whilst additionally rejecting periodic load side disturbances, a feature previously unrealisable except by other, high-gain control schemes that impose small stability margins

Evidence-based design: theoretical and practical reflections of an emerging approach in office architecture

Evidence-based design is a practice that has emerged only relatively recently, inspired by a growing popularity of evidence-based approaches in other professions such as medicine. It has received greatest attention in design for the health sector, but has received less in office architecture, although this would seem not only to be beneficial for clients, but increasingly important in a changing business environment. This paper outlines the history and origins of evidence-based practice, its influence in the health sector, as well as some of the reasons why it has been found more difficult to apply in office architecture. Based on these theoretical reflections, data and experiences from several research case studies in diverse workplace environments are presented following a three part argument: firstly we show how organisational behaviours may change as a result of an organisation moving into a new building; secondly we argue that not all effects of space on organisations are consistent. Examples of both consistent and inconsistent results are presented, giving possible reasons for differences in outcomes. Thirdly, practical implications of evidence-based design are made and difficulties for evidence-based practice, for example the problem of investment of time, are reflected on. The paper concludes that organisations may be distinguished according to both their spatial and transpatial structure (referring to a concept initially introduced by Hillier and Hanson in their study of societies). This means that evidence-based design in office architecture needs to recognise that it deals with a multiplicity of possible organisational forms, with specific clients requiring case-dependent research and evidence gathering. In this evidence-based design practice differs markedly from evidence-based medicine. Finally, we suggest a framework for systematic review inclusion criteria in the development of Evidence-Based Design as a field of practice. We argue that it is only through the development of an approach tailored to the specific nature of design practice and organisational function that research evidence can properly be brought to bear

Effective workplaces – bridging the gap between architectural research and design practice.

Architectural researchers and design practitioners mostly segregate in distinct communities with hardly any overlap, collaboration or exchange of ideas. This gap between research and practice leads to a wide-spread ignorance and inability to make practical use of evidence produced by research, resulting too often in poor designs and a self-absorbed research that cannot make a difference to peoples’ everyday lives and spatial experience. In order to bridge the gap between architectural research and design practice, UCL’s Bartlett School of Graduate Studies and Spacelab Ltd. have commited themselves to a Knowledge Transfer Partnership on Effective Workplaces. Ideas and concepts on how to change architectural business to combine research and practice will be presented as well as the first analytical results from this newly started venture

Comparative studies of offices pre and post — how changing spatial configurations affect organisational behaviours

Understanding the way in which design interventions in an office affect everyday users, and thus shape organisational behaviour, should be high on the agenda for architects, designers and consultants alike. Surprisingly, this seems rarely to be the case. Here we aim to help close this gap by studying a variety of organisations in depth both before and after an office move from the point of view of design practice. This paper thus aims at understanding how a newly designed office is seen, used and filled with life by staff, so that planners can continuously and systematically reflect on and learn from experience, and create effective and well-used workplaces for the future. The research and reflective practice presented in this paper resulted from a collaboration on 'Effective Workplaces' between The Bartlett School of Graduate Studies at University College London and Spacelab architects. Insights from in-depth case studies conducted over the last four years on various corporate clients in the media sector in the UK will be drawn upon. The studies each compared an organisation before and after it moved into a Spacelab-designed office. Two different lines of argument will be presented: firstly, results of the pre-post comparison of organisations before and after moving into a newly designed space suggest that physical space influences the way in which organisations communicate, interact, and perform in many ways. Secondly, the practical side of evidence-based design will be discussed. It can be seen that designers would do things differently if they had had the specific evidence prior to the design process. At the same time, difficulties arise in conducting 'evidence-based' practice, for example the problem of time in a business environment where designers are often asked to deliver solutions within days or weeks, whereas gaining a good understanding of a complex organisation may take months. These issues will be reflected on. General conclusions on the use and usefulness of Space Syntax in an architectural practice will be drawn

VLBI detection of an Infrared-Faint Radio Source

Infrared-Faint Radio Sources represent a new and unexpected class of object which is bright at radio wavelengths but unusually faint at infrared wavelengths. If, like most mJy radio sources, they were either conventional active or star-forming galaxies in the local Universe, we would expect them to be detectable at infrared wavelengths, and so their non-detection by the Spitzer Space Telescope is surprising. Here we report the detection of one of these sources using Very Long Baseline Interferometry, from which we conclude that the sources are driven by Active Galactic Nuclei. We suggest that these sources are either normal radio-loud quasars at high redshift or abnormally obscured radio galaxies.Comment: accepted by MNRA

It’s better together: The psychological benefits of singing in a choir

Previous research has suggested that singing in a choir might be beneficial for an individual’s psychological well-being. However, it is unclear whether this effect is unique to choral singing, and little is known about the factors that could be responsible for it. To address this, the present study compared choral singing to two other relevant leisure activities, solo singing and playing a team sport, using measures of self-reported wellbeing, entitativity, need fulfilment and motivation. Questionnaire data from 375 participants indicated that choral singers and team sport players reported significantly higher psychological well-being than solo singers. Choral singers also reported that they considered their choirs to be a more coherent or ‘meaningful’ social group than team sport players considered their teams. Together these findings might be interpreted to suggest that membership of a group may be a more important influence on the psychological well-being experienced by choral singers than singing. These findings may have practical implications for the use of choral singing as an intervention for improving psychological well-being

Persistent currents of noninteracting electrons

We thoroughly study the persistent current of noninteracting electrons in one, two, and three dimensional thin rings. We find that the results for noninteracting electrons are more relevant for individual mesoscopic rings than hitherto appreciated. The current is averaged over all configurations of the disorder, whose amount is varied from zero up to the diffusive limit, keeping the product of the Fermi wave number and the ring's circumference constant. Results are given as functions of disorder and aspect ratios of the ring. The magnitude of the disorder-averaged current may be larger than the root-mean-square fluctuations of the current from sample to sample even when the mean free path is smaller, but not too small, than the circumference of the ring. Then a measurement of the persistent current of a typical sample will be dominated by the magnitude of the disorder averaged current.Comment: 10 pages, 4 figure
