Meeting the challenge of zero carbon homes : a multi-disciplinary review of the literature and assessment of key barriers and enablers

Within the built environment sector, there is an increasing pressure on professionals to consider the impact of development upon the environment. These pressures are rooted in sustainability, and particularly climate change. But what is meant by sustainability? It is a term whose meaning is often discussed, the most common definition taken from the Bruntland report as “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs” (World Commission on Environment and Development, 1987). In the built environment, the sustainability issues within the environment, social and economic spheres are often expressed through design considerations of energy, water and waste. Given the Stern Report’s economic and political case for action with respect to climate change (Stern, 2006) and the IPCC’s Fourth Assessment Report’s confirmation of the urgency of the climate change issue and it’s root causes (IPCC, 2007), the need for action to mitigate the effects of climate change is currently high on the political agenda. Excess in carbon dioxide concentrations over the natural level have been attributed to anthropogenic sources, most particularly the burning of carbon-based fossil fuels. Over 40% of Europe’s energy and 40% of Europe’s carbon dioxide emissions arise from use of energy in buildings. Energy use in buildings is primarily for space heating, water heating, lighting and appliance use. Professionals in the built environment can therefore play a significant role in meeting targets for mitigating the effects of climate change. The UK Government recently published the Code for Sustainable Homes (DCLG, 2006). Within this is the objective of development of zero carbon domestic new build dwellings by 2016. It is the domestic zero carbon homes agenda which is the focus of this report. The report is the culmination of a research project, funded by Northumbria University, and conducted from February 2008 to July 2008, involving researchers from the Sustainable Cities Research Institute (within the School of the Built Environment) and academics, also from within the School. The aim of the project was to examine, in a systematic and holistic way, the critical issues, drivers and barriers to building and adapting houses to meet zero carbon targets. The project involved a wide range of subject specialisms within the built environment and took a multi-disciplinary approach. Practitioner contribution was enabled through a workshop. The focus of this work was to review the academic literature on the built environment sector and its capabilities to meet zero carbon housing targets. It was not possible to undertake a detailed review of energy efficiency or micro-generation technologies, the focus of the research was instead in four focussed areas: policy, behaviour, supply chain and technology.What follows is the key findings of the review work undertaken. Chapter One presents the findings of the policy and regulation review. In Chapter Two the review of behavioural aspects of energy use in buildings is presented. Chapter Three presents the findings of the review of supply chain issues. Chapter Four presents the findings of the technology review, which focuses on phase change materials. A summary of the key barriers and enablers, and areas for future research work, concludes this report in Chapter Five. Research is always a work in progress, and therefore comments on this document are most welcome, as are offers of collaboration towards solutions. The School of the Built Environment at Northumbria University strives to embed its research in practical applications and solutions to the need for a low carbon economy

Sustainability appraisal and public examination of a regional spatial strategy

UK spatial planning guidance now recognises the importance of engaging stakeholders in appraisal processes at an early stage in the plan-making process. Regional Planning Authorities are required to consult proactively with a wide range of stakeholders on both the development of planning policy and the sustainability appraisal of that policy. However, there is no clear indication as to how they might go about this process, other than to confront the various stakeholders with a Sustainability Appraisal Report. Participation in Sustainability Appraisal therefore still relies on reaction to a technical appraisal of an existing plan – and in this situation stakeholders might lack the incentive to participate. More thoughtful ways need to be devised to involve people in the sustainability debate – so that spatial policy more accurately reflects their knowledge and aspirations. The focus of this paper is to investigate ways in which Sustainability Appraisal of spatial plans can be made more accessible and transparent within the context of wider governance mechanisms. Of particular interest is the Public Examination of a Regional Spatial Strategy. The following research questions attempt to address the gaps in knowledge: 1. How can the quality and extent of engagement of stakeholders be improved, so that policy approaches delivered via Sustainability Appraisal more effectively reflect their ambitions, whilst continuing to meet the objectives for sustainability ? 2. How can the sustainability issues that might form the basis of discussions in a proactive engagement of interests be identified, and how can these issues be framed within a contextual setting that is meaningful to a range of stakeholders ? 3. What mediatory techniques can be identified to accommodate the various frames of reference that arise in potentially conflict situations

Urban wind power and the private sector : community benefits, social acceptance and public engagement

Given the ambitious government targets for renewable energy generation in the UK, there has been a push by government and industry towards various types and scales of Renewable Energy Technologies (RETs). This paper explores the implications of commercial urban wind projects for local communities, drawing on a case study of proposals by ASDA to construct wind turbines in two semi-urban locations in the UK. The paper argues that community responses to the proposals were complex and varied and could not adequately be encapsulated by 'nimby' (not in my back yard) assignations. It concludes that while ASDA followed a process of consulting local people, this process highlighted the problems of the 'business as usual' approach to public engagement employed by ASDA, and assumptions made about public acceptance of RETs

Reflections from Research in Gender and Ethics: Building Stronger Health Systems (RinGs)

Gender analysis is an important component of health systems research (HSR) as it reveals how power relations create inequalities in health system needs, experiences, and outcomes among women, men, and people of other genders. Various challenges must be overcome to successfully mainstream gender into health systems practice and research

The importance of gender analysis in research for health systems strengthening

This editorial discusses a collection of papers examining gender across a range of health policy and systems contexts, from access to services, governance, health financing, and human resources for health. The papers interrogate differing health issues and core health systems functions using a gender lens. Together they produce new knowledge on the multiple impacts of gender on health experiences and demonstrate the importance of gender analyses and gender sensitive interventions for promoting well-being and health systems strengthening. The findings from these papers collectively show how gender intersects with other axes of inequity within specific contexts to shape experiences of health and health seeking within households, communities and health systems; illustrate how gender power relations affect access to important resources; and demonstrate that gender norms, poverty and patriarchy interplay to limit women’s choices and chances both within household interactions and within the health sector. Health systems researchers have a responsibility to promote the incorporation of gender analyses into their studies in order to inform more strategic, effective and equitable health systems interventions, programmes, and policies. Responding to gender inequitable systems, institutions, and services in this sector requires an ‘all hands-on deck’ approach. We cannot claimto take a ‘people-centred approach’ to health systems if the status quo continues

Encrypting Messages for Incomplete Chains of Certificates

A public key infrastructure (PKI) binds public keys to the identities of their respective owners. It employs certificate authorities or a web of trust over social links to transitively build cryptographic trust across parties in the form of chains of certificates. In existing PKIs, Alice cannot send a message to Bob confidentially until a complete chain of trust from Alice to Bob exists. We observe that this temporal restriction---which may be severely limiting in some contexts like whistleblowing---can be eliminated by combining webs of trust with concepts from hierarchical identity-based encryption. Specifically, we present a novel protocol that allows Alice to securely send a message to Bob, binding to any chain of social links, with the property that Bob can decrypt the message only after trust has been established on all links in the chain. This trust may be established either before or after Alice has sent the message, and it may be established in any order on the links. We prove the protocol\u27s security relative to an ideal functionality, develop a prototypical implementation and evaluate the implementation\u27s performance for a realistic environment obtained by harvesting data from an existing web of trust. We observe that our protocol is fast enough to be used in practice

Psychological Resilience, Fragility and the Health Workforce: Lessons on Pandemic Preparedness from Liberia and Sierra Leone

COVID-19 presents a time to redefine vulnerability; however, in discussions of vulnerability, the health workforce, particularly in regard to their psychosocial well-being, is often forgotten. Healthcare workers (HCWs) in fragile settings are constantly exposed to health system shocks, including; conflict, disease outbreaks and natural disasters, which compound the everyday challenges of working in an under-resourced health system. Based on a commitment to serve their communities, they often cope with repeated shocks and protracted crises through innovation and creative thinking. However, they also experience repeated acute and chronic stressors that can lead to psychological distress. For some, prolonged exposure to risk of psychological distress can lead to personal growth, for others, continuous exposure to chronic stress and uncertainty can lead to psychological injury
