Zero and low carbon buildings: A driver for change in working practices and the use of computer modelling and visualization
Buildings account for significant carbon dioxide emissions, both in construction and operation. Governments around the world are setting targets and legislating to reduce the carbon emissions related to the built environment. Challenges presented by increasingly rigorous standards for construction projects will mean a paradigm shift in how new buildings are designed and managed. This will lead to the need for computational modelling and visualization of buildings and their energy performance throughout the life-cycle of the building.
This paper briefly outline how the UK government is planning to reduce carbon emissions for new buildings. It discusses the challenges faced by the architectural, construction and building management professions in adjusting to the proposed requirements for low or zero carbon buildings. It then outlines how software tools, including the use of visualization tools, could develop to support the designer, contractor and user

Software engineering challenges: Achieving zero carbon buildings by 2019
The planet Earth is warming up. There is an urgent need to reduce greenhouse gas emissions. Buildings account for almost 50% of UK carbon dioxide emissions. [1] The UK Government have set out a programme to make all new buildings zero carbon by 2019. This will require a paradigm shift in how buildings are designed, with an increased reliance on computational modelling of building performance early in the design process.
This paper outlines how architects have traditionally worked, the available software and how it is used. It discusses the challenges faced by building designers in achieving zero carbon buildings and then outlines how software tools might develop to meet not only the zero carbon challenge but also take the concept further to help design sustainable buildings

A software vision to enable the holistic design of low carbon buildings
The need to reduce the energy used by buildings and the resultant carbon emissions is changing how they are designed, look and work. This position paper outlines the urgent need for new software that integrates thermal simulation with building information modelling. A vision for the software is presented
No sex scandals please, we're French: French attitudes towards politicians' public and private conduct
The notion of distinct ‘public’ and ‘private’ spheres underpins much normative and practical engagement with political misconduct. What is less clear is whether citizens draw distinctions between misdemeanours in the ‘public’ and ‘private’ spheres, and whether they judge these in systematically different ways. This paper explores attitudes to political misconduct in France. French citizens are often said to be particularly relaxed about politicians’ private affairs, but there has been little empirical evidence for this proposition. Drawing on original survey data, this paper demonstrates clearly that French citizens draw a sharp distinction between politicians’ public and private transgressions, and are more tolerant of the latter
Zone modelling and visualisation: keys to the design of low carbon buildings
A new approach to building modelling software, to support the iterative design of energy efficient buildings, is proposed. The proposal is for the combination of two, previously separate, software types - building design modelling and building performance simulation, along with the development of a third component - a design advisor, into one software tool. This software is intended for use by architectural practices, who may not have access to energy expertise, and who may then struggle to maintain design standards for non-domestic buildings required to satisfy rigorous energy performance regulations.
In this paper we describe, through an example, how the three components would work together, by the employment of zone meshes, to visualise, simulate and support with information and advice, the design of a building. The novelty of the method resides in the application of underlying zone meshes for the support of iterative building design. The approach is described, illustrated and future work outlined
Shattering a Cartesian Sceptical Dream
Scepticism about external world knowledge is frequently claimed to emerge from Descartes’s dreaming argument. That argument supposedly challenges one to have some further knowledge — the knowledge that one is not dreaming that p — if one is to have even one given piece of external world knowledge that p. The possession of that further knowledge can seem espe-cially important when the dreaming possibility is genuinely Cartesian (with one’s dreaming that p being incompatible with the truth of one’s accompany-ing belief that p). But this paper shows why that Cartesian use of that possi-bility is not at all challenging. It is because that putative sceptical challenge reduces to a triviality which is incompatible with the sceptic’s having de-scribed some further piece of knowledge which is needed, if one is to have the knowledge that p.Freqüentemente, argumenta-se que o ceticismo sobre o mundo exterior surge do argumento do sonho, de Descartes. Supõe-se que esse argumento nos de-safia a ter algum conhecimento mais — o conhecimento de que não estamos sonhando que p — se devemos ter qualquer conhecimento, em relação o mundo exterior, de que p. Ter esse outro conhecimento pode parecer especi-almente importante quando a possibilidade de estarmos sonhando é genui-namente cartesiana (sendo que estarmos sonhando que p seria incompatível com a verdade das crenças que também temos de que p). Mas esse artigo mostra por que o uso cartesiano dessa possibilidade não é de forma alguma desafiador. É proque aquele suposto desafio cético se reduz a uma trivialida-de que é incompatível com o fato de ter o cético descrito algum outro conhe-cimento que é necessário, se devemos ter o conhecimento de que p
Knowledge as Potential for Action
Can we conceive cogently of all knowledge – in particular, all knowledge of truths – as being knowledge-how? This paper provides reasons for thinking not only that is this possible, but that it is conceptually advantageous and suggestive. Those reasons include adaptations of, and responses to, some classic philosophical arguments and ideas, from Descartes, Hume, Peirce, Mill, and Ryle. The paper’s position is thus a practicalism – a kind of pragmatism – about the nature of knowledge, arguing that all knowledge is knowledge-how to act – to do this, to do that. Such a conception can include, too, a distinctive view of the metaphysical relation between knowledge and belief. We see that, contrary to what most contemporary epistemologists say, knowledge need not be a form of belief. Instead, a belief that p can be a way simply of enriching or strengthening knowledge that p. It can do this in a paracticalist way, by allowing one to do more with the knowledge
Free Will as a Sceptical threat to knowing
Sceptics standardly argue that a person lacks knowledge due to an inability to know that some dire possibility is not being actualised in her believing that p. I argue that the usual sceptical Inventory of such possibilities should include one' s possibly having had some freedom in forming one's belief that p. A sceptic should conclude that wherever there might have been some such freedom, there is no knowledge that p. (This is not to say that sceptics would be correct in that conclusion. It is just to say that the usual sceptical way of thinking should welcome the possibility of some such belief-freedom as much as it routinely welcomes the possibilities of dreaming and of evil demons.
The rationales of New Labour's cultural policy 1997-2001
The cultural policies of New Labour, devised by the first British government department of "culture", the DCMS, have been noted for their conceptual inconsistencies and unsupportable claims, yet the rationales behind them have never been adequately explained. This thesis argues that, when seen from an historical perspective, the intentions of the Secretary of State, Chris Smith, and the DCMS in fact followed a consistent logic by which cultural policy was re-conceptualised to take DCMS into the heart of government where social and economic concerns dominated. Building on the principle of cross-government policy and the "pillars" of excellence, access, education, and the creative economy, DCSM claimed a foundational role for culture in propagating the roots of economic growth formed around theories of social capital. In doing so, it shifted the traditional balance between the public and private realms, compromised traditions of laissez-faire, instituted new mechanisms of governance, and marginalised the arts. The thesis concludes that Chris Smith and the DCMS sought power by arguing a role for culture in social and economic policy initiatives; an ambition that could not be achieved with policies for culture in its traditional meaning. The conceptual incoherence that resulted was ignored as insignificant to its purposes
