Occupant behaviour simulation for cellular offices in early design stages - Architectural and modelling considerations

Building simulation is most useful and most difficult in early design stages. Most useful since the optimisation potential is large and most difficult because input data are often not available at the level of resolution required for simulation software. The aim of this paper is to addresses this difficulty, by analysing the predominantly qualitative information in early stages of an architectural design process in search for indicators towards quantitative simulation input. The discussion in this paper is focused on cellular offices. Parameters related to occupancy, the use of office equipment, night ventilation, the use of lights and blinds are reviewed based on simulation input requirements, architectural considerations in early design stages and occupant behaviour considerations in operational stages. A worst and ideal case scenario is suggested as a generic approach to model occupant behaviour in early design stages when more detailed information is not available. Without actually predicting specific occupant behaviour, this approach highlights the magnitude of impact that occupants can have on comfort and building energy performance and it matches the level of resolution of available architectural information in early design stages. This can be sufficient for building designers to compare the magnitude of impact of occupants with other parameters in order to inform design decisions. Potential indicators in early design stages towards the ideal or worst case scenario are discussed.

Optimal VM placement in data centres with architectural and resource constraints

Recent advance in virtualisation technology enables service provisioning in a flexible way by consolidating several virtual machines (VMs) into a single physical machine (PM). The inter-VM communications are inevitable when a group of VMs in a data centre provide services in a collaborative manner. With the increasing demands of such intra-data-centre traffics, it becomes essential to study the VM-to-PM placement such that the aggregated communication cost within a data centre is minimised. Such optimisation problem is proved NP-hard and formulated as an integer programming with quadratic constraints in this paper. Different from existing work, our formulation takes into consideration of data-centre architecture, inter-VM traffic pattern, and resource capacity of PMs. Furthermore, a heuristic algorithm is proposed and its high efficiency is extensively validated.

The Catuspatha pattern in Balinese palace: architectural conservation and challenges

Balinese architecture was established prior to European colonization and significantly enhances traditional Balinese values that are woven into the predominant Hindu religion. Palaces are integral to the architectural heritage of Bali and were dated back to the Majapahit Empire. Balinese palaceswere constructed for non-ritualistic activities in this historical cultural landscape. Palaces were often located on road corners called catuspatha1andthey possess sacred values embodied in the concept of pempatanagung.Although Bali Province is today governed as one governance unit, these palaces still reflect their own multiple regal associations which arestill respected by Balinese society. The representations and architecture of these palaces andthe communicative symbols of a heyday era of Bali are raising questions as to how they can be accommodated within the over-arching tourism development and globalization of culture that Bali is experiencing. Therefore, this paper reviews pre-colonial Balinese palaces, their architecture, the catuspatha concept, and considers the traditional values of these ancient monuments as to conservation of palaces and their associated cultural heritage. An extensive literature review, surveys and observational inventories were undertaken at several palaces to obtain results that raise new questions about how these complexes can withstand globalization challenges whilst respecting traditional Balinese culture and society.

Democratic corporealities of love : the architectural cinema and eroticized publics of Pauline Kael

The American film critic Pauline Kael’s career interestingly parallels the Cold War period but nobody has explored this yet. Filling that gap, this essay constructs Kael’s writings and critic’s persona as a contribution to a discourse of international democracy. Kael was part of a generation of American critics who took seriously the importance of art to politics. However, she goes further than her contemporaries by energizing this relationship through her emphasis on corporeality—both on screen and off screen—and on the eroticized body. A discernible philosophical lineage runs from Plato’s version of love as described by Socrates in The Symposium to Kael’s writings and bodily habits. In this lineage, love is figured as relational and desiring. A second line of relationship between Plato and Kael is in the way they each connected erotic discourses to the very similar architectures of the andrôn (men’s quarters), for Plato, and the modern American cinema or screening room, for Kael. Plato and Kael draw out the inherent spatial energy of these places (which is most evident at the borders of andrôn and cinema) through the interactions they construct of images and talk with the erotic, love-based relationality of bodies. They thereby maximize the bodily powers of these architectures as places where a public of differences and (inevitably) “loose” democracy might form. Kael’s advocacy doesn’t suggest a formal political program so much as a more feminine democracy of erotic discourses allied to an energizing architecture suitable to the accumulation of plural, participatory corporealities.
