    This paper presents an ARTMAP-incorporated multi-agent system (MAS) for building heat management, which aims to maintain the desired space temperature defined by the building occupants (thermal comfort management) and improve energy efficiency by intelligently controlling the energy flow and usage in the building (building energy control). Existing MAS typically uses rule-based approaches to describe the behaviours and the processes of its agents, and the rules are fixed. The incorporation of artificial neural network (ANN) techniques to the agents can provide for the required online learning and adaptation capabilities. A three-layer MAS is proposed for building heat management and ARTMAP is incorporated into the agents so as to facilitate online learning and adaptation capabilities. Simulation results demonstrate that ARTMAP incorporated MAS provides better (automated) energy control and thermal comfort management for a building environment in comparison to its existing rule-based MAS approach

    Climate change and variability, energy and disaster management: produced risks without produced solutions: rethinking the approach

    Accelerated climate change and increasing climate variability is the single largest threat to the international goals of sustainable development, the Millennium Development Goals (MDGs) and disaster risk reduction. Global discourses recognise the need for effective and sustainable responses tso produced climate risks. The risk types likely to occur are known, but only in broad terms - their scale, severity, longevity and frequency are not known. The challenge for policymakers is developing an effective framework within which sustainable responses can be formulated. To address the problems of produced risks a comprehensive approach to risk management is necessary. The mechanisms within the climate change, sustainable development and disaster risk reduction discourses are not sufficiently effective or integrated to respond to this challenge. Fundamental reform to current modes of risk reduction is needed, but this can only be achieved through a shift in the dominant perspective on formulating sustainable responses. This requires a shift to an enabling policy framework that encourages bottom-up resilient responses. Resilience is argued as a tool for policy development that can enhance adaptive capacity to current climate risks and shape energy policy to respond to mitigate future climate risks

    University-Community Collaboration for Climate Justice Education and Organizing: Partnerships in Canada, Brazil, and Africa

    In the coming decades, countries around the world will face increasingly severe challenges related to global climate change. While the details vary from country to country, the impacts will be especially grave for marginalized people, whose access to food, potable water, and safe shelter may be threatened due to fluctuations in rainfall and temperature and to disasters related to extreme weather events. International strategies for addressing climate change are in disarray. The complicated financial and carbon-trading mechanisms promoted by the United Nations and other global institutions are far too bureaucratic, weak, internally inconsistent, and scattered to represent meaningful solutions to climate change. Already the housing, health, and livelihoods of marginalized people worldwide are being threatened by the ramifications of climate change. This means that the marginalized in every community, by definition, have expertise in how priorities should be set to address climate change. Their experiences, knowledge, and views must be part of local, regional, national, and international governance—including urban planning and housing, water management, agriculture, health, and finance policies.This research was supported by the International Development Research Centre, grant number IDRC GRANT NO. 106002-00

    Theoretical multiplicity for the governance of transitions. The energy producing greenhouse case

    Get PDF
    Transition management, as a theory of directing structural societal changes towards sustainable system innovations, has become a major topic in scientific research over the last years. In the Netherlands, the concept of transition management was adopted by several governmental agencies as one of the leading principles for steering sustainable development. In this paper we focus on the governance of transitions. The question is if and how transitions towards sustainability can be steered, governed or managed, in particular by governmental actors. We suggest an approach of theoretical multiplicity, arguing that multiple theories will be needed simultaneously for dealing with the complex societal sustainability issues. Therefore, we address the governance question by theoretically comparing transition management theory to a number of related theories on societal change and intervention, such as multi-actor collaboration, network governance, policy agenda setting and adaptive governance. We argue that these related theories put the managerial assumptions of transition management into perspective, by adding other steering roles and leadership mechanisms to the picture. We will illustrate the advantages of theoretical multiplicity by analysing the case of the greenhouse as a source of energy. The energy producing greenhouse can be considered a revolutionary technology, with the potential of turning the greenhouse horticultural sector from a mass energy consumer into a sustainable energy user and producer

    Fostering energy efficiency dynamics through ex-ante strategic niche management: the UK perspective

    Get PDF
    The United Kingdom building sector has been challenged to retrofit a huge stock of existing buildings in order to increase its adaptive capacity for climate change impacts. Addressing such challenges will require systematic structural changes in both, socio-technical and socio-political infrastructure. A numbers of studies have suggested the approach of strategic niche management of transition for sustainable technological regimes. Accordingly, any such transition would follow processes: early stages of niche formation; creation of policy mechanism required to harness the niches; niche expansion into incumbent regime; and the regime transition into more sustainable technological regime. Following this, the UK Government has introduced a raft of initiatives; one of which is “Green Deal” to enable buildings to become energy efficient through retrofit technologies, ultimately contributing towards the national goal of achieving 80% reduction in carbon emission by 2050. This paper serves three purposes. First, the paper introduces multi-level socio-technical system for construction/retrofitting in building industry. Second, the ex-ante strategic niche management approach has been used to analyse the dynamic of “Green Deal” initiative. Thereby the paper would critically assess technological, organisational and institutional reforms undertaken for the initiative in the processes for sustainable socio-technical transition. Third, the paper would contribute towards strategic niche management literature which lacks in practical examples of using it as an ex-ante tool for niche building and regime transition

    International partnerships of women for sustainable watershed governance in times of climate change

    This chapter describes and assesses collaborative research with women actively engaged in local and global community engagement processes for water management in times of global climate change. As an equity-focused response to climate change, the interrelated networks and initiatives described in the chapter involve organizations and individuals in Brazil, Mozambique, South Africa, Kenya, and Canada. These collaborations are focused on strengthening low-income women's voices, and legitimizing their knowledge and action within water management institutions and processes. The chapter draws from what people learned through two international projects, the Sister Watersheds project with Canadian and Brazilian partners, and a Climate Change Adaptation in Africa project with partners in Canada, Kenya, Mozambique, and South Africa. The methods and approach of the Sister Watersheds project proved to be applicable to climate change education and organizing in Canada as well as in Brazil. The chapter summarizes that women are working together on climate education and water governance, helping to inspire and generate related strategies.This research was supported by the International Development Research Centre, grant number IDRC GRANT NO. 106002-00
