Research in UK and elsewhere has highlighted that older people are particularly vulnerable to negative health effects of overheating. This paper examines the magnitude, causes, preparedness and remedies for addressing the risk of summertime overheating in four case study residential care and extra-care settings across the UK, spanning different building types, construction and age. The methodological approach adopted is interdisciplinary, drawing from building science and social science methods, including temperature monitoring, building surveys, and interviews with design and management teams. The findings suggest that overheating is a current and prevalent risk in the case study schemes, yet there is currently little awareness or preparedness to implement suitable and long-term adaptation strategies (eg. external shading). There was a perception from designers to managers, that cold represents a bigger threat to older occupants' health than excessive heat. A lack of effective heat management was found across the case studies that included unwanted heat gains from the heating system, confusion in terms of responsibilities to manage indoor temperatures, and conflicts between window opening and occupant safety. Given that care settings should provide protection against risks from cold and hot weather, design, management and care practices need to become better focused towards this goal.

Most research to date on the provision of energy feedback to households has focused on assessing the efficacy of numeric-based feedback. This paper describes the application and evaluation of more visual energy feedback techniques (carbon mapping, thermal imaging) at different scales, alongside traditional methods (web-based energy and environmental visualization platform, home energy reports) delivered through community workshops, home visits and the internet, across six low-carbon communities in the UK. Overall, most of the feedback approaches were able to engage and raise awareness amongst the householders. Whilst carbon mapping was felt to be aimed more at community groups and local councils by providing evidence of past and future community action, displaying carbon maps at community workshops helped to show that others were also engaged in energy action. Thermal imaging was successful in engaging individual local residents through both community workshops and home visits, especially when included in the home energy reports. This stimulated discussions on future energy savings through building fabric upgrade. However, the data-driven web-based platform had limited uptake due to online log-in requirement and information overload. Such insights are useful for those involved in scaling up the deployment of energy feedback to encourage energy demand reduction.

AbstractPurpose -This paper aims to, using a systematic mixed-methods based monitoring and evaluation approach, investigate the unintended consequences of physical and technical home improvements on energy use, indoor environmental conditions and occupant behaviour in community-led retrofits. The study is part of a UK Research Council funded research project on evaluating the impacts and effectiveness of low carbon communities on energy behaviours. Design/methodology/approach -A graduated measurement, monitoring and evaluation framework has been developed and applied to gather quantitative and qualitative data on energy use and behaviours has been developed and applied to 88 households across the UK. A mixed-methods approach is used, including occupant interviews, questionnaires, activity diaries and continuous physical monitoring of energy use, environmental conditions and low-carbon technologies. Findings -The study has uncovered a number of unintended consequences associated with home energy improvements, both beneficial and detrimental, including improved comfort levels in retrofitted dwellings and reduction in energy use but also an increased likelihood of overheating following fabric improvements, potential under-performance of low-carbon systems due to lack of understanding and inadequate installation and commissioning, along with adaptive energy behaviours leading to increased energy use and a widening gap between predicted and actual savings. Research limitations/implications -Although 63 case study households are involved, it is difficult to provide statistical analysis from the emerging findings. Practical implications -This paper demonstrates the unintended consequences of home energy improvements. It aims to bring awareness of these issues to various sectors and stakeholders involved in delivering community retrofit programmes or the National Green Deal programme. Originality/value -The paper fulfils an identified need to study the impacts of home energy improvements within existing homes through a robust, comprehensive M&E approach.
