    Seeking the Pressure Points: Catalysing Low Carbon Changes from the Middle-Out in Offices and Schools

    Non-domestic buildings are frequently characterised as resistant to top-down low-carbon and energy-efficiency policy. Complex relationships amongst building stakeholders are often blamed. “Middle actors”—professionals situated between policymakers and building users—can use their agency and capacity to facilitate energy and carbon decision-making from the “middle-out”. We use semi-structured interviews with expert middle actors working with schools and commercial offices, firstly, to explore their experience of energy and low-carbon decision-making in buildings and, secondly, to reflect on the evolution of middle actors’ role within it. Our exploratory findings suggest that a situated sensitivity to organisational “pressure points” can enhance middle actors’ agency and capacity to catalyse change. We find shifts in the ecology of the “middle”, as the UK’s Net Zero and Environmental, Social and Governance (ESG) agendas pull in new middle actors (such as the financial community) and issues (such as wellbeing and social value) to non-domestic buildings. These issues may work in reinforcing ways with organisational pressure points. Policy should capitalise on this impetus by looking beyond the physicality of individual buildings and engage with middle actors at a systemic level. This could create greater synergies with organisational concerns and strategies of building stakeholders

    Global carbon mechanisms: emerging lessons and implications

    Get PDF
    The global carbon mechanisms have succeeded in channelling billions of Euros towards low-carbon investments in developing countries, but cannot deliver what is needed in the future without support including reforms and involvement of North America. The publication shows that the Clean Development Mechanism itself has triggered more than 4000 emission-reducing projects in developing countries and is likely to save up to 2 billion tonnes of emissions reductions by 2012. Other Mechanisms under the Kyoto Protocol, including emerging Green Investment Schemes, show great promise. But many of the gains are at peril, warns the publication, unless governments act to restore balance in the markets and learn the emerging lessons. The publication identifies and analyses three fundamental problems that must be tackled. An excess of supply over demand will mean low prices in the market without government action There must be reforms to improve the efficiency and environmental performance of the existing mechanisms The Global Carbon Mechanisms are and will continue to be a central pillar in the global response to climate change to 2020, but are not on their own sufficient. They need to be complemented by other action to support the required cuts in carbon emission

    Talking about targets: How construction discourses of theory and reality represent the energy performance gap in the United Kingdom

    Get PDF
    Targets for energy performance in operation have been advocated as a solution to the well-documented mismatch between the expected and actual energy use of buildings. Although construction industry actors will be crucial in realising these targets, their response to them is currently under-explored. Augmenting research on how middle actors shape energy consumption, this paper examines how everyday talk in the construction industry sustains this mismatch, drawing on a study of a hospital construction project with targets for energy in use. It applies Gilbert and Mulkay's approach to discourse analysis, particularly their interest in “accounting for error”, to data drawn from interviews with actors across the construction project, observation of daily life on site, and an examination of written interactions. Findings show how actors make a discursive division between the “theory” and “reality” of energy use. Expressing scepticism about “theory”, in particular, allows them to rationalise problems with future operational energy consumption and thereby mitigate their professional liability. This division therefore perpetuates, rather than overcomes, the separation between energy in design and operation, displacing a more collaborative discussion of performance expectations. This challenges the assumption that targets for energy in use can be effective without accompanying changes in industry incentives and ways of working. This paper argues for more attention to the patterns of talk that are found in the construction industry, in order to uncover how this crucial set of actors will respond to new energy policy incentives

    Transport, Growth Mechanisms, and Material Quality in GaN Epitaxial Lateral Overgrowth

    Get PDF
    Growth kinetics, mechanisms, and material quality in GaN epitaxial lateral over-growth (ELO) were examined using a single mask of systematically varied patterns. A 2-D gas phase reaction/diffusion model describes how transport of the Ga precursor to the growth surface enhances the lateral rate in the early stages of growth. In agreement with SEM studies of truncated growth runs, the model also predicts the dramatic decrease in the lateral rate that occurs as GaN over-growth reduces the exposed area of the mask. At the point of convergence, a step-flow coalescence mechanism is observed to fill in the area between lateral growth-fronts. This alternative growth mode in which a secondary growth of GaN is nucleated along a single convergence line, may be responsible for producing smooth films observed to have uniform cathodoluminescence (CL) when using 1{micro}m nucleation zones. Although emission is comprised of both UV ({approximately}365nm) and yellow ({approximately}550nm) components, the spectra suggest these films have reduced concentrations of threading dislocations normally associated with non-radiative recombination centers and defects known to accompany growth-front convergence lines

    Risk factors for early language delay in children within a minority ethnic, bilingual, deprived environment (Born in Bradford’s Better Start): a UK community birth cohort study

    Get PDF
    Background: Preschool language skills and language delay predict academic and socioemotional outcomes. Children from deprived environments are at a higher risk of language delay, and both minority ethnic and bilingual children can experience a gap in language skills at school entry. However, research that examines late talking (preschool language delay) in an ethnically diverse, bilingual, deprived environment at age 2 is scarce. Methods: Data from Born in Bradford’s Better Start birth cohort were used to identify rates of late talking (≤10th percentile on the Oxford-Communicative Development Inventory: Short) in 2-year-old children within an ethnically diverse, predominantly bilingual, deprived UK region (N=712). The relations between known demographic, maternal, distal and proximal child risk factors, and language skills and language delay were tested using hierarchical linear and logistic regression. Results: A total of 24.86% of children were classified as late talkers. Maternal demographic factors (ethnicity, born in UK, education, financial security, employment, household size, age) predicted 3.12% of the variance in children’s expressive vocabulary. Adding maternal language factors (maternal native language, home languages) and perinatal factors (birth weight, gestation) to the model predicted 3.76% of the variance. Adding distal child factors (child sex, child age) predicted 11.06%, and adding proximal child factors (receptive vocabulary, hearing concerns) predicted 49.51%. Significant risk factors for late talking were male sex (OR 2.07, 95% CI 1.38 to 3.09), receptive vocabulary delay (OR 8.40, 95% CI 4.99 to 14.11) and parent-reported hearing concerns (OR 7.85, 95% CI 1.90 to 32.47). Protective factors were increased household size (OR 0.85, 95% CI 0.77 to 0.95) and age (OR 0.82, 95% CI 0.70 to 0.96). Conclusions: Almost one in four children living in an ethnically diverse and deprived UK area have early language delay. Demographic factors explained little variance in early vocabulary, whereas proximal child factors held more predictive value. The results indicate further research on early language delay is warranted for vulnerable groups

    Evidence-informed urban health and sustainability governance in two Chinese cities

    Get PDF
    Sustainable development is best supported by intersectoral policies informed by a range of evidence and knowledge types (e.g. scientific and lay). Given China’s rapid urbanisation, scale and global importance in climate mitigation, this study investigates how evidence is perceived and used to inform urban health and sustainability policies at central and local levels. Well-informed senior professionals in government/scientific agencies (12 in Beijing and 11 in Ningbo) were interviewed. A thematic analysis is presented using deductive and inductive coding. Government agency participants described formal remits and processes determining the scope and use of evidence by different tiers of government. Academic evidence was influential when commissioned by government departments. Public opinion and economic priorities were two factors that also influenced the use or weight of evidence in policymaking. This study shows that scientific evidence produced or commissioned by government was routinely used to inform urban health and sustainability policy. Extensive and routine data collection is regularly used to inform cyclical policy processes, which improves adaptive capacity. This study contributes to knowledge on the ‘cultures of evidence use’. Environmental governance can be further improved through increased data-sharing and use of diverse knowledge types
