'Public Sculpture (The Social)' 2010

Commisssioned by Frieze Art for the Frieze Sculpture Park The project presents the image of a sculpture as a sculpture, installed in the form of a large scale digital print on vinyl stretched over a 14 x 28ft (4.2 x 8.4m) stretcher supported by a scaffolding structure. The image itself depicts a futuristic public sculpture, an ‘impossible’ artwork, referencing Ballard’s descriptions in his book ‘Vermillion Sands’. The work also draws upon examples of rococo ornamentation and the compositional conventions of ‘images of sculpture’ (in art magazines, catalogues, publicity photos) including examples sited in Regents park in previous years. Technical details: The image is printed on vinyl, stretched over a 14 x 28ft (4.2 x 8.4m) wooden stretcher and fixed to a deep buttressed scaffold 8m long by 6.23 deep with IBC water tanks on the back edge as kentledge (4 x I tonne IVC water containers - 1 per bay). The structure is constructed from clean silver Layher system scaffold and wrapped by a dense black mesh netting.

Particle image velocimetry measurements of turbulent flow within outdoor and indoor urban scale models and flushing motions in urban canopy layers

We investigate the spatial characteristics of urban-like canopy flow by applying particle image velocimetry (PIV) to atmospheric turbulence. The study site was a Comprehensive Outdoor Scale MOdel (COSMO) experiment for urban climate in Japan. The PIV system captured the two-dimensional flow field within the canopy layer continuously for an hour with a sampling frequency of 30 Hz, thereby providing reliable outdoor turbulence statistics. PIV measurements in a wind-tunnel facility using similar roughness geometry, but with a lower sampling frequency of 4 Hz, were also done for comparison. The turbulent momentum flux from COSMO, and the wind tunnel showed similar values and distributions when scaled using friction velocity. Some different characteristics between outdoor and indoor flow fields were mainly caused by the larger fluctuations in wind direction for the atmospheric turbulence. The focus of the analysis is on a variety of instantaneous turbulent flow structures. One remarkable flow structure is termed 'flushing', that is, a large-scale upward motion prevailing across the whole vertical cross-section of a building gap. This is observed intermittently, whereby tracer particles are flushed vertically out from the canopy layer. Flushing phenomena are also observed in the wind tunnel where there is neither thermal stratification nor outer-layer turbulence. It is suggested that flushing phenomena are correlated with the passing of large-scale low-momentum regions above the canopy.

Can objects perform?: agency and thingliness in contemporary sculpture and installation

In his 1967 essay, “Art and Objecthood”, Michael Fried bemoaned the theatricality of minimalist sculpture, which replaced the presentness of compositional sculpture with the staging of an experience for the viewer as performer. His argument has since been inverted by artists and art writers invested in the idea of sculptures as props forming part of an artistic experience economy. This discourse has accompanied the rise of relational aesthetics as a dominant paradigm for contemporary art. More recently, however, there has been a turn away from relationality to ‘object-oriented’ art, where objects are seen to stage their own theatrical experiences, performing themselves without requiring the activation of a viewer’s body. We trace parallels between the philosophy of Bruno Latour and the “Speculative Materialism” group and this emerging trend in sculpture. In ascribing agency to objects, Latour proposes a radical shift from philosophy’s traditional investigation of the relationship between the mind and the world. Drawn to the idea that matter can be creative, artists have embraced his thinking. However, we argue that this has lead to a generalized, universalizing humanism that disables political action. Moreover, it undermines the potential for anti-humanist critique latent in object-oriented philosophy.

Local space for local people? Trends in the provision and management of urban outdoor recreation in the UK

This paper examines the growing trend in the UK towards the effective privatisation of formerly public open space and the relationship of this trend to the recent shifts in public sector management. A case study of Reading, England, illustrates the growing cultural and spatial dysfunction, particularly in terms of the declining knowledge and use of the town's urban gardens by the local population. Where once the gardens were a focus of social activity, therefore, they are now a largely irrelevant site of urban decline. In contrast to central urban space, it is clear that other types of open space in other areas can still assume a significance in peoples' lives. In many cases the use of these areas illustrates a counter cultural position in which the consumerism of the city management is actively being resisted. The paper concludes that while there appear to be ways in which local space could be reclaimed for local people, the power to achieve this lies predominantly in the same hands as those responsible for appropriating central space to the imperative of the market in the first instance

Analysis of Direct Outdoor Air Cooling Efficency for Combined Variable Air Volume Air-conditioning System in Stores in Cold Climates of China

Direct outdoor air cooling contributes a lot not only to the improvement of the indoor air quality but also to the energy saving. Its full use will reduce the water chiller’s running time especially in some stores where cooling load keeps much higher and longer than that in other buildings. A novel air-conditioning system named Combined Variable Air Volume system (CVAV), combining a normal AHU with a separate outdoor air supply system, was proposed firstly by the authors. The most attractive feature of the system is its full utilization of cooling capacity and freshness of outdoor air in the transition period of the year round. On the basis of the obtain of the dynamic cooling loads of the typical shopping malls in different four cities located in cold climates in China with the aid of DOE-2, the possibility of increasing the amount of outdoor air volume of CVAV system in the transition period instead of operating the water chillers was confirmed. Moreover, a new concept, Direct Outdoor Air Cooling Efficiency (DOACE), was defined as the ratio of cooling capacity of outdoor air to the water chiller, indicating the degree of outdoor air’s utilization. And the DOACE of the CVAV was calculated and compared with that of conventional all-air constant volume air-conditioning systems, the results showed that CVAV bear much more energy saving potential with the 10%~19% higher DOACE and it is a kind of energy efficient systems and can improve the indoor air quality as well.

Meteorological forcing data for urban outdoor thermal comfort models from a coupled convective boundary layer and surface energy balance scheme

Site-specific meteorological forcing appropriate for applications such as urban outdoor thermal comfort simulations can be obtained using a newly coupled scheme that combines a simple slab convective boundary layer (CBL) model and urban land surface model (ULSM) (here two ULSMs are considered). The former simulates daytime CBL height, air temperature and humidity, and the latter estimates urban surface energy and water balance fluxes accounting for changes in land surface cover. The coupled models are tested at a suburban site and two rural sites, one irrigated and one unirrigated grass, in Sacramento, U.S.A. All the variables modelled compare well to measurements (e.g. coefficient of determination = 0.97 and root mean square error = 1.5 °C for air temperature). The current version is applicable to daytime conditions and needs initial state conditions for the CBL model in the appropriate range to obtain the required performance. The coupled model allows routine observations from distant sites (e.g. rural, airport) to be used to predict air temperature and relative humidity in an urban area of interest. This simple model, which can be rapidly applied, could provide urban data for applications such as air quality forecasting and building energy modelling, in addition to outdoor thermal comfort.

The aims of early years outdoor education in England: a conceptual and empirical investigation

This paper explores the place of aims in the early years foundation stage outdoor environment in England. Through examining the writing of academics, various themes are identified, and constructed into possible aims. These themes/aims are compared to an empirical study of early years teachers’ attitudes. Data was collected by questionnaire from schools within the University of Reading partnership. There was general agreement between experts and teachers as to the aims. While some respondents were able to explain what the aims of outdoor activity were, a significant number were unable to identify aims; further, a significant number did not distinguish between approach/practice and aims. A lack of understanding and agreement as to what the aims are may indicate teachers are unsure about the purpose of outdoor education for young children. A result of this study is to agree and make explicit the aims for outdoor education in the early years.
