The airtightness and air leakage characteristics of new UK holiday homes

It is estimated that in the UK, 200,000 residents live in park and holiday homes all year round, the majority of which are elderly and on low incomes. As these homes are often thermally inefficient and leaky, these residents are some of the most susceptible in society to fuel poverty. Despite this, there is a dearth of empirical data available on the in situ fabric performance of these homes. This paper presents the results obtained from undertaking a series of pressurisation tests and leakage identification on new build holiday homes. While the sample size reported is small, the results indicate almost a factor of two variation in the airtightness performance of the homes. In spite of this, all of the homes achieved an air permeability significantly lower than the default value incorporated within the industry standard Energy Efficiency Rating Calculator, suggesting that a much lower figure may be more appropriate. The results also suggest that the use of the air permeability metric within the Calculator potentially biases the performance of holiday homes due to their particular form factor, and that this bias could be mitigated against by adopting the air leakage metric within any future revisions to the Calculator

Business Improvement Districts in England and the (private?) governance of urban spaces

Business Improvement Districts (BIDs) were introduced in England just over ten years ago, and their adoption in over 180 locations all over the country owes a great deal to their potential ability to raise private funds to invest in the development of business areas. However, much of the academic literature on BIDs has been critical of what it sees as an expansion of corporate control of urban spaces and the weakening of elected local government, often on the evidence of a long-running North American debate. On the basis of ten case studies of English BIDs, in this paper I address the evolution of those organisations as private stakeholder-led instruments for the governance and management of business areas in England. I discuss whether and to what extent English BIDs constitute private government of urban areas, and the attendant issues of accountability and spatial inequalities in the distribution of public services and investment. I conclude by examining the implications of its findings for the future of urban governance

Infrastructure, planning and the command of time

​Governments in many countries have sought to accelerate the time taken to make decisions on major infrastructure projects, citing problems of ‘delay’. Despite this, rarely has the time variable been given careful empirical or conceptual attention in decision-making generally, or in infrastructure decision-making specifically. This paper addresses this deficit by analysing decision-making on two categories of major infrastructure in the UK – transport and electricity generation – seeking both to generate better evidence of the changes to decision times in recent decades, and to generate insights from treating time as resource and tracking its (re)allocation. We find that reforms introduced since 2008 have done relatively little to alter overall decision times, but that there are marked and revealing changes to the allocation of time between decision-making stages. While public planning processes have their time frames tightly regulated, aspects led by developers (e.g. pre-application discussion) are not; arranging finance can have a bigger effect on project time frames, and central government retains much flexibility to manage the flow of time. Speed-up reforms are also sectorally uneven in their reach. This indicates how arguments for time discipline falter in the face of infrastructure projects that remain profoundly politicised

Visitor expenditure estimation for grocery store location planning: a case study of Cornwall

Visitor expenditure is an important driver of demand in many local economies, supporting a range of services and facilities which may not be viable based solely on residential demand. In areas where self-catering accommodation is prevalent visitor demand makes up a considerable proportion of sales and revenue within grocery stores, yet this form of visitor consumption is commonly overlooked in supply and demand-side estimates of visitor spend. As such, store location planning in tourist resorts, decisions about local service provision and the local economic impacts of tourism are based on very limited demand-side estimates of visitor spend. Using Cornwall, South West England as a study area, we outline a methodology and data sources to estimate small-area visitor grocery spend. We use self-catering accommodation provision, utilisation and visitor expenditure rates as key factors driving visitor spend. We identify that the use of visitor accommodation accounts for the spatial and temporal complexities of visitor demand that may be overlooked when using alternative approaches, such as the up-scaling of residential demand. Using a spatial interaction model, we demonstrate that our expenditure estimates can be used to generate store level revenue estimation within tourist resorts, and we make a number of recommendations for service provision and store location planning in these areas

The changing regulatory environment for speculative housebuilding and the construction of core competencies for brownfleld development

Speculative housebuilding in the United Kingdom faces an ever tighter regulatory environment owing to the increasing impact of the sustainable development agenda. For example, 60% of all new homes in England are now expected to be constructed on previously developed land or provided through the conversion of existing buildings. As speculative housebuilders are responsible for about 80% of all new dwellings built in the United Kingdom, the achievement of this important government target is critically dependent on the ability and willingness of the private sector to respond to public policy. By exploring the main components of the residential development process, the author investigates how far speculative housebuilding will need to change to ensure the successful implementation of the government's brownfield housing target. He suggests that those speculative housebuilders that are enthusiastically building up core competencies in brownfield housing are likely to emerge as the market leaders of the future whereas those companies that continue to rely on past practices and technologies will face an uncertain future as greenfield development opportunities begin to reduce

Deconstructing spatial planning: reinterpreting the articulation of a new ethos for English local planning

This article reviews recent debates about the emergence of “spatial planning” as a new ethos for English planning, suggesting that continued uncertainty around the term's use is partly caused by a failure to consider its emergence as the product of a contested political process. Drawing on an interpretive approach to policy analysis, the article goes on to show how this new organizing principle is a complex articulation of different and potentially contradictory reform impulses. The result is to destabilize the concept of spatial planning, showing how it has been constructed as an “empty signifier”, an unstable and tension-filled discursive stake in an ongoing politics of reform. Finally, it is argued that this has significant implications for the ways in which implementation success and failure should be understood and for analysis of planning reform initiatives and systems more widely
