Evaluation of the use of Home Energy Monitoring and Management Systems (HEMS) to support adoption of renovation measures: D2.3.1. Evaluation report HEMS
No full textIn the current context of energy transition, practices for reducing energy consumption are encouraged by many local authority schemes, in particular for households. Homeowners are called upon to change their energy practices to save money, while ensuring better comfort in the home.Home Energy Monitoring or Management Systems (HEMS) are tools that homeowners can use to increase their energy awareness. Municipalities hope that – by providing HEMS to homeowners - this will lead to the adoption of energy-saving measures. This study therefore aimed to explore how LAs can adopt HEMS distribution actions, and if the adoption of provided HEMS by homeowners can affect the energy use behaviour and willingness of homeowners to adopt also other low-carbon technologies.The study used innovation adoption theory and a qualitative research method on the adoption of HEMS, supported by quantitative insights. It uses the insights from seven Local Authorities (LAs) from four countries (Belgium, France, The Netherlands, UK), who evaluated their actions to have homeowners adopt HEMS, as well as the energy behaviour in target areas using demo exemplars.The study first categorises HEMS types based on the factors that might affect the adoption of home energy renovation measures. Second, it investigates adoption parameters according to each adoption phase for local authorities, as well as homeowners. Third, it analyses homeowners experiences through an ex ante and ex post HEMS installation survey. Finally, it assesses the recommendations suggested by participating local authorities.The study finds that HEMS actions can be embedded in other LA actions regarding sustainability awareness raising and housing renovation. LAs particularly value that HEMS can support them with more accurate real-time energy use and comfort data. However, HEMS should be carefully selected and tested based on cost efficiency, ease of installation, compatibility with the energy management and legal system, simplicity of the feedback and supporting administration and data access arrangements.The majority of homeowners who installed the HEMS were (highly) satisfied with the HEMS installed in their house and already convinced before the installation that the HEMS would help them to save energy. More than half of the individuals also reported energy-related behavioral change. About 30% of the individuals invested in energy-saving measures, while 70% had not adjusted anything. The adoption of HEMS can support homeowners’ behavioral change but does not necessarily lead to adoption of renovation measures by homeowners.On the one hand, homeowners are likely to change their behaviour if they would get options beyond simple digital meters, on the other hand LAs find their role to help homeowners adopting more advanced HEMS as a complex one-off experiment. Collaboration is key for upscaling the adoption of HEMS.Housing Managemen

Impact of Home Energy Monitoring and Management Systems (HEMS): Triple-A: Stimulating the Adoption of low-carbon technologies by homeowners through increased Awareness and easy Access D2.1.1. Report on impact of HEMS
No full textThis report answers the question: How can HEMS be used to influence energy-saving behaviour of homeowners? Lessons regarding the feedback from HEMS to influence energy-saving behaviour have been explored and specifications of HEMS to influence energy saving by households are given.Generally, the implementation of the Triple-A HEMS should appeal to (1) end-users (households) and (2) local authorities. Triple-A partners will provide HEMS to households to encourage them to change their energy behaviour and to trigger interest in the adoption of low carbon technologies. Another goal is to apply HEMS in demonstration exemplars (WP 4) to monitor the energy consumption of households and analyse consumption data before and after applying low carbon technologies.HEMS with real time feedback have a good potential to influence the energy use and subsequent savings of households. In order to realise a structural change of the energy use behaviour it also must become customary for households to use the feedback system. The need of forming an energy saving habit also sets demands on the functionality and design of the feedback system. It must meet the preferences, capabilities and interest of a heterogonous group of homeowners or should be designed for specific customer segments. Direct feedback instruments primarily influence low-cost-quick-win measures: simple changes in behaviour that require little or no effort or investments. These behavioural changes however can potentially lead to substantial immediate savings.The rollout of smart meters and HEMS differs strongly between the EU countries and the Triple-A countries. Energy providers can play an important role in the rollout of HEMS. The use of smart meters and HEMS and providing easy access of HEMS to homeowners could be one of the instruments of local energy saving programs and community-based reinforcement strategies of local authorities. A neighbourhood approach aims to enable more positive outcomes for energy savings and uptake of renovation measures, by using peer-to-peer communication, personal advice, trialling in demo houses and demonstration in pop-up centres and on local authority websites.To monitor actual CO2 savings by local authorities within the demonstration areas, baseline requirements for HEMS deal with recording (or accessing data related to) annual energy use gas and/or electricity within the properties for a period of 12 months before and after installation. Next to baseline requirements local authorities can choose discretionary functions and requirements of HEMS, including e.g. measuring grid energy monitoring and comfort performance.HEMS will also be used to give real-time feedback of the energy use to homeowners helping them to manage their energy consumption. For this purpose recommendations are:• HEMS should be easy to use and accessible, and fit for purpose.• Feedback should be real-time, frequent feedback enables the user to link behaviour to consequences.• The specifications of the HEMS should match with the household characteristics and the willingness to use HEMS. A distinction between user groups is advisable: some users explicitly have more interest in more functionalities (and thus a more complex HEMS, others want a more intuitive user interface.• Whether adoption of HEMS leads to the adoption of renovation measures is not (yet) known.• HEMS should appeal to certain conditions of the homeowner (segments) or to solving issues within the home.Overall recommendations for choosing HEMS include:• The HEMS should be cost-effective.• The installation of the HEMS should be easy (preferentially without electricity connection).• The intrusion time for installing in the home should be minimized.• A preference is given for HEMS that local authorities can experiment with free-of-charge to avoid de minimis statements.• HEMS choice by local authorities will be influenced by the need to follow up KPI’s for energy saving, and thus by the compatibility with their own energy management system for analysing building stocks.Project No. 2S02-029OLD Housing Quality and Process InnovationHousing Managemen
Design of a data collector for HEMS crew during OHCA
No full textThe HEMS crew is planning to conduct research on implementing ECPR treatment during OHCA cases. A data collector that collects time and chest compression data is needed for the research. Thus, this graduation project is focused on the design of a data collector for HEMS crew during OHCA. This report describes the whole process of developing the design of the data collector. The process starts with a design brief that elaborates the design assignment. Then four cycles of project development are carried out: the first cycle is focused on context analysis and exploration of possible solutions; the second cycle is focused on the electronics prototype and data transfer system building; the third cycle is focused on the housing design of the collector; the last cycle is concluded with a validated final design and recommendations on implementation. This project collaborates with Dr. Dinis Reis Miranda from the HEMS lifeliner 2 and Erasmus MC - University Medical Center.Integrated Product Desig
Evaluation of overweight and obesity in Helicopter Emergency Medical Service (HEMS) worker
No full textIntroduction
Obesity now affects people from all walks of life, including those who work in the field of medical aid provision on a daily basis. So far, there has been no research assessing the nutrition status of Helicopter Emergency Medical Service (HEMS) crews.
Objectives
To evaluate the degree to which overweight and obesity prevail among Helicopter Emergency Medical Service Air Ambulances (HEMS LPR) crew members, and determine the overall excess body fat and fatty tissue distribution in the subjects.
Material and methods
In order to evaluate the prevalence of overweight and obesity in HEMS crew members, the following anthropometric measurements were used: height, body mass, waist and hip circumferences. Assessment of their nutritional status was made by using some generally used indicators, i.e. calculating the subjects’ BMI, WHR and WHtR.
Results
Pilots were older than the paramedics in a statistically significant way. On the basis of using the BMI indicator, it was shown that only 36% of HEMS crew members had normal body weight. Analysis of the percentage of body fat determined that 61.5% of the paramedics and 39.4% of the pilots had normal weight. 26.2% paramedics and 28.8% pilots were diagnosed as overweight. Obesity characterised 12.3% of paramedics and 31.8% of pilots. The above were statistically significant differences (p= 0.0117). Waist circumference exceeded 102 cm in 25.9% of the subjects and WHR&amp;gt;1 characterised 20.6% of those examined.
Conclusions
Analysis of the results obtained revealed that an alarmingly high percentage of crew members suffer from excessive body mass and fat, particularly in the group of pilots. Immediate action should be taken in order to reduce the body mass and introduce preventive measures among the subjects
How safe are HEMS-programmes in Germany?
No full textThies K-C, Sep D, Derksen R. How safe are HEMS-programmes in Germany? Resuscitation. 2006;68(3):359-363.Introduction
Recent accidents with helicopter emergency medical service (HEMS) aircraft raise the question how safe HEMS in Germany is and how accidents could be prevented.
Materials and methods
We surveyed all German HEMS-programmes and reviewed the data of the German Aviation Authority regarding accidents with HEMS.
Results
An average German HEMS-programme encounters one accident leading to at least severe damage or loss of the helicopter in 26 operating years, one accident resulting in casualties in 65 operating years and one fatal accident in 111 operating years. The major causes of accidents were obstacle strikes during landing at the scene. Flying in bad weather conditions and lack of discipline were other factors contributing to HEMS-accidents.
Conclusion
HEMS-safety could be improved by special training programmes for pilots and HEMS-crewmembers to address the factors listed above. Safety training for doctors is recommended but we did not find support for the notion of changing the doctor's legal position of a passenger to a HEMS-crewmember
Exploring Potential Roles of Home Energy Management System (HEMS) as Boundary Objects: A Case Study in Taiwan
No full textThe integration of Home Energy Management Systems (HEMS) into Taiwan's smart grid infrastructure has been a cornerstone in enhancing energy efficiency. However, uncertainties persisted regarding the extent to which HEMS could effectively bridge the energy efficiency gap. This study investigated HEMS' role as boundary objects, capable of transcending knowledge barriers within complex socio-technical systems. To address these concerns, a comprehensive methodology was employed, guided by a mixed-methods approach comprising a systematic literature review and an interview. The development of the evaluative framework drew insights from the understanding of complex systems and the concept of boundary objects, uncovering the intricate interplay of elements, relationships, and emergent patterns. This framework served to illuminate the nuanced dynamics underlying HEMS adoption, fostering meaning creation and collective efforts, ultimately paving the path for enhanced energy efficiency. The findings elucidated multifaceted interactions between technology, user behaviour, and knowledge boundaries, collectively shaping the potential for energy efficiency enhancement. By amalgamating theoretical insights with practical experiences, the study furnished a comprehensive comprehension of the potential role of HEMS in effectively bridging the energy efficiency gap within Taiwan's evolving smart grid landscape. This research bestowed valuable insights for enhancing energy efficiency and navigating the intricate terrains of energy management, echoing beyond the confines of Taiwan and resonating in the global pursuit of sustainable energy utilisation.Applied Science
