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

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

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

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

Environmentally Friendly Synthesis of Transition Metalorganic Hybrid Nanocomposites

Research on metal nanoparticles (MNPs) synthesis and their applications for optoelectronic devices has been a recent interest in the fields of nanoscience and nanotechnology Photovoltaics are one of such systems in which MNPs have shown to be quite useful, due to unique physical, optical, magnetic, and electronic properties, including the metal nanoparticles synthesized in this research. Owing to the challenges with the most common physical and chemical methods of preparing MNPs, including the use of high temperatures, toxic reducing agents, and environmentally hazardous organic solvents, there is a critical need for a benign synthesis procedure for MNPs. In this work, a simple, versatile, and environmentally and economically responsible synthesis method for making iron, nickel, zinc, and bimetallic alloy nanoparticles (ANPs) has been developed and functionalization with organic capping agents were performed to form metal-organic hybrid nanocomposites with tunable properties. The size, shape, elemental composition, photophysical properties, and crystallinity of particles and their hybrids have been evaluated. Monometallic nanostructures of iron, nickel, and zinc oxide were synthesized via aqueous-phase reduction of metal(II) chloride salts with sodium borohydride. Upon optimization of the standard method described here, reaction parameters like reaction time, reagent molar ratios, and capping-agent molar ratio were evaluated. Characterization techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive x-ray (EDS), IR, and UV-visible spectroscopies, selected area electron diffraction (SAED), and power x-ray diffraction (XRD) were performed as necessary. Well-defined, reproducible nickel and iron nanoparticles were produced with average diameters of 26±4 nm and 50±26 nm, respectively, arranged into chain-like structures. Much smaller (6-9 nm) zinc oxide particles that self-assembled into single-particle thick, hexagonal hierarchical microstructures were formed from a modified standard method. Similarly, iron-nickel ANPs with the average size of 20.9±3.3 nm were also synthesized and successful grafting with the polymer capping agent, polyvinylpyrrolidone was confirmed. Because of size, ordered self-assembly, and benign synthesis procedure, the nanoparticles described here are ideal candidates for photovoltaic and thermoelectric device applications. Moreover, these particles have shown to disperse well in various organic and inorganic media, and therefore have wide versatility in thin-film deposition methods

Transport and Spectra in the Half-filled Hubbard Model: A Dynamical Mean Field Study

We study the issues of scaling and universality in spectral and transport properties of the infinite dimensional particle--hole symmetric (half-filled) Hubbard model within dynamical mean field theory. One of the simplest and extensively used impurity solvers, namely the iterated perturbation theory approach is reformulated to avoid problems such as analytic continuation of Matsubara frequency quantities or calculating multi-dimensional integrals, while taking full account of the very sharp structures in the Green's functions that arise close to the Mott transitions and in the Mott insulator regime. We demonstrate its viability for the half-filled Hubbard model. Previous known results are reproduced within the present approach. The universal behavior of the spectral functions in the Fermi liquid regime is emphasized, and adiabatic continuity to the non-interacting limit is demonstrated. The dc resistivity in the metallic regime is known to be a non-monotonic function of temperature with a `coherence peak'. This feature is shown to be a universal feature occurring at a temperature roughly equal to the low energy scale of the system. A comparison to pressure dependent dc resistivity experiments on Selenium doped NiS$_2$ yields qualitatively good agreement. Resistivity hysteresis across the Mott transition is shown to be described qualitatively within the present framework. A direct comparison of the thermal hysteresis observed in V$_2$O$_3$ with our theoretical results yields a value of the hopping integral, which we find to be in the range estimated through first-principle methods. Finally, a systematic study of optical conductivity is carried out and the changes in absorption as a result of varying interaction strength and temperature are identified.Comment: 19 pages, 12 figure
