The work of the UK Climate Change Commission (UKCCC) in recommending targets and options for reducing emissions of greenhouse gases is focusing attention on what agriculture and land use can contribute to deliver these targets. Although overall the major issue is the reduction of carbon dioxide emissions from energy use, agriculture and land use are significant emitters of methane and nitrous oxide. UKCCC has identified three main routes by which emissions can be reduced• Lifestyle change with less reliance on carbon intensive produce -eg switching from sheep, and beef to pig, poultry and vegetables.• Changing farm practices – eg to improve use of fertilisers and manures• Using new technology on farms – eg modifying rumen processes, anaerobic digestion.

The Smart Meter Rollout Programme in the UK has required energy suppliers to offer new smart meters to customers to provide near real-time energy use information and enable two-way communication between the meter and the central system. The provision was expected to result in meaningful energy reductions, but recent estimates suggest that these reductions may be as low as 2%. This paper contributes to the ongoing debate about the effectiveness of smart meters and in-home energy displays by providing insights on energy feedback perceptions from a series of focus groups with postgraduate consumers. In addition to domestic energy use, the study investigated how participants perceived their energy use at work and how they perceived the energy reduction efforts of their institutions and employers. A laddered and projective methodology was used to more deeply question participant perceptions and reveal their attitudes. The analysis of responses revealed a limited awareness around energy efficiency strategies and opportunities for more visual, mobile, engaging and target-driven interfaces for energy data. The findings also agree with previous observations that environmental concerns are not a key driver of energy reduction behaviours. This was shown by laddered questioning, not to be due to a lack of environmental concern, but rather the perception that reducing energy consumption would have negligible impact. A decade after in-home energy displays enabled a means of providing ‘visibility’ to ‘invisible’ energy consumption, little appears to have changed in the perception and experience of energy feedback.

Awareness of the logic and context of original (and subsequent) design priorities is critical to informing decisions relating to valorisation, repair, refurbishment, energy retrofit or re-use of built heritage. A key benefit of collating data through Historic Building Information Modelling (HBIM) should be to assist others facing similar challenges. Here, examples for sharing understanding of how components belong to a system are outlined in the context of a newly completed dataset of public library buildings in the UK funded by Andrew Carnegie, predominantly built between 1900 and 1914. Demands for the functionality and economy of public library buildings, coupled with the emergent standardisation of building components at the time, provide a specific condition with potential for further iteration to other buildings of the period or related typologies. The work highlights the urgency of providing cost-efficient knowledge sharing structures in an era of altered priorities with respect to energy use for modern heritage. We propose the means for mapping common features to network knowledge amongst stakeholders through relevant open source pathways. The results demonstrate that integrating geographic approaches to knowledge sharing in HBIM with environmental considerations also supports wider questions of risk management related to the stewardship of historic buildings in the context of climate change.

A set of three scenarios has been created in order to examine the incorporation of extensive penetrations of micro-generators into electricity networks (termed ‘highly distributed power systems’). The scenarios have been created as a synthesis of the Future Network Technologies scenarios and the UK domestic carbon model, and yields energy use and carbon dioxide emissions of the UK housing stock from inputs of household numbers, house type, thermal efficiency, appliance efficiency, as well as the number and efficiency of micro-generators used. The centralized supply mix also varies between scenarios and features extensive penetrations of large-scale renewables. The scenarios illustrate the scale of change required to reduce CO2 emissions by 60 per cent by 2050, which has substantial impacts for electricity network operation. Moving from a centralized system to the one where one-third of electricity comes from distributed sources poses significant challenges including: reverse power flow on networks, load balancing, storage requirements, phase unbalance, harmonics, and ancillary services.

Taking its cue from the UK government's declaration that every new home should be ‘zero-carbon’ by 2016, this paper explores how close a flexible, prototype-housing model might come to meeting this target (accepting that there is currently some ambiguity between the respective official ‘zero-carbon’ definitions regarding off-site renewable supply). The prime aim is to design economically (affordable by housing associations) to the European ‘passive house’ standard of no more than 15 kWh/m2 for space heating and a maximum total consumption of 70 kWh/m2 adding in hot water and electricity. The model also prioritizes generous access to sunlight and daylight, as well as realistic levels of air change in a low-volume, intensively occupied scenario. Associated aims are: a) to meet thermal loads without use of fossil fuels such as gas or oil; and b) to employ architecturally integrated active solar thermal and electrical arrays to respectively meet at least one third of the water heating and electrical loads. Micro-wind generation is excluded from the study as too site-dependent. A subsidiary agenda is to achieve a flexible plan in terms of orientation and access, and to provide utility facilities that support the environmental strategy (e.g. drying clothes without compromising energy use or air quality). The paper goes on to address equivalent prospects for retrofit, briefly discusses institutional and other barriers to achievement, and muses on how much of the balance of the electrical demand can be met renewably in Scotland in the near future.

AbstractThere is now no doubt that current global production-consumption-disposal systems are threatening the fundamental conditions of existence on this planet. In response, the pressing need for total system transformation has gained civic and political traction, feeding into long-standing debates and interventions that are aimed at recalibrating prevailing economic and social practices. One such debate and intervention is that of the circular economy (CE). Here, advocates argue that current linear resource and energy use systems must be reconfigured into loops of re-use, repair, refurbishment, and recycling, displacing primary production and lessening greenhouse gas emissions in the process. This agenda has potentially profound implications for aspects of daily social practices. Yet, to date, little attention has been paid (politically and in research) to how the CE does and will interact with everyday habits, norms, and meanings. In response, this paper explores some of the conceptual assumptions underlying the CE ‘consumer’. It argues that mainstream CE debates are underscored by an impoverished view of our relationships with complex material cultures, which in turn is creating barriers to transformation. Drawing on empirical research into responses to the CE in the UK and the Netherlands, this paper contrasts the challenges of inciting consumers to take up new, resource-efficient business models in contexts of hyper-consumerism, with a more hopeful ‘small story’ of overt, small-scale circular spaces, that nevertheless embed the CE and its underlying impetuses more clearly into the everyday.
