Towards a just heat transition in the building sector: A study on social indicators of sustainability

Heating in UK buildings is dominated by fossil fuels as the main energy source, representing over 80% of the household energy consumption and 79% of the carbon emissions. Therefore, heat decarbonisation in this sector should be accelerated in order to achieve the 2050 net zero carbon targets. However, there is still a great deal of uncertainty regarding the social impacts of heat decarbonisation strategies on households and the communities. The multiplicity of social criteria and inconsistency of their measuring methods complicate the assessment of social sustainability in the energy systems, leading to less incorporation of the social factors in design and decision-making processes. Therefore, identifying a set of indicators that represent the social performance of energy systems is an essential for conducting a holistic sustainability assessment. In this research, a methodological process is established primarily aimed to identify, select, and prioritise a representative set of indicators that can reflect the social sustainability of the heating transition in the building industry. The research accounts for a qualitative survey and judgments of experts to determine the indicators and their importance weights thus reducing the subjectivity and uncertainties of the process. The result is a social sustainability assessment framework that will enable decision-makers to evaluate the transition pathways, select the best alternatives, and monitor their performance, by analysing social indicators in conjunction with other sustainability parameters.publishedVersionPeer reviewe

Planning energy interventions in buildings and tackling fuel poverty : Can two birds be fed with one scone?

Energy retrofitting and renovations are an inseparable part of decarbonisation strategies in the building sector. These measures are often tied up with several social factors that can potentially impact the wellbeing of households and the community if the end-user requirements are not carefully considered. Fuel poverty is one of these social factors that is an essential consideration for designing effective, just, and user-centred interventions, but it is often overlooked in engineering processes. Therefore, this article seeks to re-connect the notion of fuel poverty to practice by bringing it forward from the post-intervention assessments to the design and decision-making stages. To do so, a new indicator, Potential Fuel Poverty Index (PFPI), is developed to obtain the likelihood of fuel poverty that future interventions can pose to the households. The PFPI presents a more targeted analysis of fuel poverty by reflecting the socio-spatial characterisation of the households. Using the PFPI, fuel poverty can be observed as a design/decision factor at the early stages of sketching interventions, in conjunction with other economic, environmental, and technical factors. Finally, the utility of the developed method is demonstrated using a real case study in the UK, assessing the impact of heat decarbonisation through heat pumps on fuel poverty.publishedVersionPeer reviewe

Learning from fall-related interventions for older people at home : A scoping review

This scoping review aims to provide a better understanding about the fall-related interventions, and the conditions which stand out as effective in decreasing fall risks of older people at home. A total of 28 peer-reviewed papers were included when they reported interventions with an incidence of falls or fall-risk as a primary outcome for older people, focusing on the home environment, from 8 databases. Qualitative examination was complemented by quantitative risk ratio analysis where it was feasible. The interventions regarding incidence of falls had a mean risk rate of 0.75; moreover, interventions using multiple strategies were found relatively successful. The interventions regarding fall risk had a mean hazard rate of 0.66. A considerable number of no-effect ratios were evident. Combining education, home assessment or improvement, and use of technology with implementation by health service experts appears to be the most promising intervention strategy to reduce falls.Peer reviewe

Energy Poverty Evaluation Using a Three-Dimensional and Territorial Indicator: A Case Study in Chile

Energy poverty (EP) is a problem that affects a large part of the world population, leaving those most vulnerable to suffer from unhealthy indoor conditions in their homes, being cold in winter months, struggling with their monetary situation, and even reducing social activities with relatives. In this context, it is important to assess EP situations and identify those factors that most affect each one. This paper, through the evaluation and adaptation of the Three-dimensional and Territorial Indicator of Energy Poverty (EPITT in Spanish), developed by the Energy Poverty Network in Chile (RedPE Chile), assesses the different EP situations in a social-housing case study located in south-central Chile. The results show different EP situations depending on the dimensions studied, e.g., 35% of households had food and hygiene issues, 27% had issues with lighting and electrical devices, 72% with climate control in the home, and 68% experienced equality in energy expenditure issues. It is possible to say that energy expenditure is the dimension that most influences the EP situation. Furthermore, the values in the different dimensions are below the national average, mainly because of the poor quality of housing, limitations in access to energy, and low income. In conclusion, the adaptation of EPTTI provides a better understanding of EP vulnerability at the local scale.publishedVersionPeer reviewe

Architectural education: methods for integrating climate change design(ccd) in the curriculum

The design and construction of buildings are responsible for 40% of the EU's energy use with an associated 36% CO2 emissions,1 significantly contributing to the climate emergency. Thus, the EU aims for climate neutrality by 2050,2 but this needs to be achieved much sooner to avoid exacerbated damage and other related crises and to ensure climate justice.3 However, in architectural education, a significant gap in Climate Change Design CCD) knowledge, skills and competencies exist for both students and educators and is one of the biggest challenges in the construction industry, as noted by the IPCC.4 Over 4000 architects in 18 countries declared 'a biodiversity and climate emergency'5 with over 2500 architecture students and teachers globally signing the ‘architecture education declares’ action with a ‘call for a curriculum change'.6 This paper, as part of the transnational ARCH4CHANGE EU Erasmus + funded project ‘Digital climate change curriculum for architectural education: methods towards carbon neutrality, presents findings from a systematic literature review, focusing on the barriers and successful pedagogical methods to meet this urgent challenge in architecture educatio

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
