Exploring the Relationship Between a ‘Facebook Group’ and Face-to-Face Interactions in ‘Weak-Tie’ Residential Communities

Using Facebook Groups to connect otherwise anonymous people that live in a single urban development is a relatively new phenomenon. Within residential developments there are a number of common management and performance issues experienced by many isolated inhabitants that are identified through building performance evaluation studies. Facebook is a ubiquitous social network tool and powerful communication platform, particularly popular among young adults. This paper explores the use of Facebook in relation to management and performance issues in two cases of Facebook Group usage within residential communities in the UK. Data was collected through longitudinal digital and physical visits to the residential communities and to the Facebook Group sites. Findings are presented in relation to home learning, site/neighbourhood and self-organising initiatives. We propose that weak-tie residential communities can develop collective efficacy and work together for the overall good of the residential development through communicating on a Facebook Group. This helps to improve the physical environment, facilitating further collective action. There is a clear overlap between social media narrative and the physical experience of daily life, which can help to empower residents

Designs on the Planet: A workshop series on architectural education and the challenges of climate change

The design of human settlements is a key factor for addressing carbon emissions, finite resource availability, ecological deterioration and climate change. The role of architectural education in promoting the principles and practices which address these issues is significant. New pedagogic paradigms are required to produce graduates endowed with holistic competences including environmental knowledge related to sustainable design. These competencies are set to become a compulsory part of professional architectural education in the UK, although the successful incorporation of technical principles within creative design still faces a number of pedagogic barriers. To address these challenges, the Designs on the Planet workshop series was set up as a national forum. Its primary aim was to contribute to the development of environmental responsibility as a creative factor in the practice and pedagogy of architecture. The workshops were attended by academics, educators, practitioners and representatives of professional bodies. This paper reviews the year-long process of DoP, presenting the conclusions of the workshops, exploring the results of the application of the pedagogic principles within participating universities and discussing new teaching methodologies and curricular structures which could facilitate overcoming the divide between sustainability- related building sciences and architectural design in higher education and professional practice

Exploring the efficacy of Facebook groups for collective occupant learning about using their homes

The need for quality learning about how to use a home has been an issue gradually emerging from building performance evaluation (BPE) studies carried out in occupied energy efficient homes (Brown & Cole, 2009; Day & Gunderson, 2014). The BPE gap between the internal environment control as intended by designers and the actual inhabitant practices is associated with unpredicted energy consumption and poor indoor air quality (Balvers et al., 2012). The key inhabitant related causes of the ‘performance gap’ are a discrepancy between user needs and design intentions, lack of user understanding and skills to interact with the available controls and insufficient maintenance. These findings indicate that modifying tacit home use practices, adjusting them to new, more technically advanced contexts, is still not sufficiently addressed by the current learning opportunities offered by the professional actors. This paper explores how self-organised closed Facebook Groups set up independently by the residents of two UK case study urban developments have become supportive environments for such learning

Overheating in retrofitted flats: occupant practices, learning and interventions

© 2016 Informa UK Limited, trading as Taylor & Francis Group The overheating risk in flats (apartments) retrofitted to energy-efficient standards has been identified by previous studies as one that is particularly high. With climate change and rising mean temperatures this is a growing concern. There is a need to understand the kinds of practices, learning and interventions adopted by the occupants of individual homes to try to reduce overheating, as this area is poorly understood and under-researched. This case study focuses on the impact of different home-use practices in relation to the severity of overheating in 18 flats in one tower block in northern England. Internal temperatures monitored in comparable flats show that the percentage of time spent above the expected category II threshold of thermal comfort according to BS EN 15251 can differ by over 70%. Extensive monitoring, covering a full year, including two summer periods, has identified emergent changes in heatwave practices linked with increased home-use skills and understanding among the research participants. Close analysis of design intentions versus reality has identified key physical barriers and social learning opportunities for appropriate adaptation in relation to heatwaves. Recommendations for designers and policy-makers are highlighted in relation to these factors

Temperature in housing: stratification and contextual factors

Overheating in new and retrofit low carbon dioxide homes is a growing issue in the UK due to climate change and other factors, with 99% of existing housing predicted to be at medium to high risk if summer temperatures become 1·4°C warmer. A year-long field study in two residential developments in the north of England monitored housing at three different scales: two-storey houses and three- and ten-storey blocks of flats. This revealed significant temperature stratification in the staircase zone, which allows a stack effect, as well as temperature differences between dwellings depending on their location in the building, both for summer and winter conditions even in the low-rise housing. Further investigation revealed that albedo and east–west orientation also contributed to non-linear overheating. Analyses of inhabitants’ thermal comfort and security practices as well as occupancy patterns also challenge the regulatory modelling used to predict building performance. It is suggested that these additional physical as well as user factors in residential developments need further investigation and should now be considered in relation to thermal comfort modelling

Embedding building performance evaluation in UK architectural practice and beyond

Despite repeated efforts to foreground Post-occupancy evaluation (POE) in many countries, few have any policy or legislation in place to mandate this process. Large scale voluntary efforts have also failed to provide successful templates through which to mainstream broader Building performance Evaluation (BPE) activity within which POE sits. This paper reviews various programmes and initiatives in the UK which have attempted to embed first POE, then BPE over the last twenty years within a global context, using a practice-based approach based on the author’s experience of working in the field over this period. Key findings are: a failure of government to systemically follow through on BPE initiatives, stakeholders operating independently of eachother, a lack of institutional engagement in the education sector as a key driver for BPE, and the potential for interdisciplinary models to embrace all members of the design team as well as the client. The paper then examines the means by which BPE has been successfully embedded into practice directly, through deep organisational learning and knowledge exchange activities. Recommendations for these models to be replicated through professional institutions, other learning organisations and regulatory frameworks in the UK are put forward in the Conclusion as a way forward

Resilience, redundancy and low-carbon living: co-producing individual and community learning

There is an acknowledged need for buildings and communities to be more resilient in the face of unpredictable effects of climate change, economic crises and energy supplies. The notion and social practices involving redundancy (the ability to switch between numerous available choices beyond optimal design) are explored as an aspect of resilience theory. Practice and Social Learning theories are used as a lens through which to explore the available redundancy in housing and home environments to help prevent performance failure through unexpected circumstances or in response to varying user needs. Findings from an in depth UK housing case study show how redundancy is linked with the capacity to share resources and to learn both individually and collectively as a community. Such learning in relation to resilient low-carbon living is shown to be co-produced effectively through participatory action research. The benefits of introducing extra redundancy in housing design and community development to accommodate varied user’s understanding and preferences are discussed in relation to future proofing, value and scalar issues. Recommendations include better understanding of the design, time and monetary contribution needed to implement social or technical redundancy. These costs should be evaluated in context of savings made through greater resilience achieved

Housing performance evaluation: challenges for international knowledge exchange

Developing effective building performance evaluation and feedback processes is a vital part of global efforts to reduce building energy use and gain insight into the actual performance of buildings and technologies. Although attempts have been made to introduce internationally agreed models for these processes, it is clear that various countries are producing different approaches according to their cultural, institutional and policy differences. Knowledge exchange is potentially a key means of developing a shared understanding of values, meanings and practices in relation to building performance evaluation. This paper identifies cultural and institutional barriers in the European Union for international building performance communities of practice utilizing knowledge exchange, from an experiential ‘real-world’ perspective. The preparation of a 30-month research project to help develop building performance evaluation in Poland and an associated bilateral symposium is closely evaluated through an action research case study in terms of the stakeholders, the national contexts in which they operated and the key challenges they faced. Recommendations are then made in terms of the support needed to develop more responsive research programmes in relation to developing international knowledge exchange, and the capacity-building elements required for these international communities of practice

Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial

Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124. Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid (5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18). Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of 5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98). Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a randomised trial
