Contextualising water use in residential settings: a survey of non-intrusive techniques and approaches

Water monitoring in households is important to ensure the sustainability of fresh water reserves on our planet. It provides stakeholders with the statistics required to formulate optimal strategies in residential water management. However, this should not be prohibitive and appliance-level water monitoring cannot practically be achieved by deploying sensors on every faucet or water-consuming device of interest due to the higher hardware costs and complexity, not to mention the risk of accidental leakages that can derive from the extra plumbing needed. Machine learning and data mining techniques are promising techniques to analyse monitored data to obtain non-intrusive water usage disaggregation. This is because they can discern water usage from the aggregated data acquired from a single point of observation. This paper provides an overview of water usage disaggregation systems and related techniques adopted for water event classification. The state-of-the art of algorithms and testbeds used for fixture recognition are reviewed and a discussion on the prominent challenges and future research are also included

Increasing Engagement in the Mirboo North Community Energy Hub

The Mirboo North Community Energy Hub (MNCEH) is a community-driven initiative designed to promote sustainability solutions. Its founding business case was prepared by Primaform, a partner in the Snowy River Innovation (SRI) group. The goal of this project was to increase community engagement in the MNCEH, particularly in the dairy farming and agroforestry sectors. Based on interviews and surveys, we identified successful community engagement strategies to recommend to the MNCEH. We also found that Mirboo North and district lacked a trusted source of energy information. We created a prototype website for the MNCEH to serve as an information source and community engagement tool

Investigating the potential for a user-driven electricity monitoring application to provide useful electricity consumption patterns

Conventional electricity usage monitoring involves complex data collection via costly and intrusive hardware installation. There is a perceived need for a simple and affordable tool that provides users with feedback about their electricity consumption without the hardware installation. This study involves the design and development of a user driven mobile and desktop application that provides users with information on electricity usage patterns and historical trends. The application was designed using Ionic Framework, a tool ideal for the design of hybrid applications that are compatible with both desktop Windows devices and mobile Android devices. The goal of the research will be that the user will track their appliance usage on the application whilst taking electricity meter readings at regular intervals to calculate appliance-specific consumption. The data is added to the mobile or desktop application, which then provides users with a comprehensive display of the electricity usage patterns and trends. The objective is to provide users with the information required so that they can start understanding their electricity consumption better and it is a first step towards empowering the user to make smart decisions at home that will reduce their electricity consumption. The USE (Usefulness, Satisfaction, Ease of Use and Ease of Learning) questionnaire was used to gather user experience feedback from participants about user experience. The USE questionnaire tests the perceived Usefulness, Satisfaction, Ease of Use and Ease of Learnability The 31 individuals who initially volunteered to take part in the study are all residents of the City of Cape Town Municipality, aged between 20 and 80 years old. Not all participants are home owners; some are tenants in their premises. The sample group was selected on a convenience basis, and social media group posts were also used to reach individuals with a potential interest in the study. The two motivating factors that were considered to identify individuals who could potentially have an interest in the study were cost saving and environmental impact. 21 volunteers completed the study and returned the USE questionnaire. The study findings showed that all participants believe that using the application helped them to better understand their electricity consumption

Sustainable consumption: towards action and impact. : International scientific conference November 6th-8th 2011, Hamburg - European Green Capital 2011, Germany: abstract volume

This volume contains the abstracts of all oral and poster presentations of the international scientific conference „Sustainable Consumption – Towards Action and Impact“ held in Hamburg (Germany) on November 6th-8th 2011. This unique conference aims to promote a comprehensive academic discourse on issues concerning sustainable consumption and brings together scholars from a wide range of academic disciplines. In modern societies, private consumption is a multifaceted and ambivalent phenomenon: it is a ubiquitous social practice and an economic driving force, yet at the same time, its consequences are in conflict with important social and environmental sustainability goals. Finding paths towards “sustainable consumption” has therefore become a major political issue. In order to properly understand the challenge of “sustainable consumption”, identify unsustainable patterns of consumption and bring forward the necessary innovations, a collaborative effort of researchers from different disciplines is needed

Dirtying Linen: Re-evaluating the sustainability of domestic laundry

In tackling and negotiating responsibility for anthropogenic climate change, governments and businesses are increasingly concerned with shaping ‘consumer behaviour’, understood broadly as the ways in which people acquire, appropriate and appreciate goods and services. One intervention considered successful in this respect has been that of encouraging the low-temperature washing of laundry in the UK in the last decade. This paper draws on data from a quantitative survey of laundry practices conducted in Britain in 2013 (N = 1502) in order to situate the intervention, and the phenomenon of low-temperature washing, in its wider socio-cultural context. Our starting point is that laundry habits are a useful example of a household practice in which changes in consumer behaviour have occurred, yet which continue to be increasingly environmentally problematic. Our analysis examines the use of washing machines and the temperature at which people do their laundry in detail; however, it also explores the broader processes through which clothing and other items become designated ‘dirty’ and go on to become ‘clean’. We argue that, in contrast to the well-documented hegemonic position of the washing machine in UK homes, there is much diversity in how households organize the other tasks involved in doing laundry, particularly in separating, sorting and drying, with important implications for energy use. To conclude, we reconsider low-temperature washing as an intervention, and outline some policy implications of a more thorough understanding of how laundry, and domestic consumption more generally, is currently handled in the UK

Strategic Concealment: Locating Armed Private Contractors in State Foreign Policy

The global expansion of armed private contractors has led to a revived interest in researching armed private contracting firms, especially investigating how their personnel have functioned as an extension of state foreign policy. However, the literature on the industry contains a confusing diversity of terms when reviewing such firms, whether private military company, private security company, private military security company, or even just mercenary. Using the Singer (2010) ‘tip of the spear’ typology, I analyze the distinctions across armed private contracting firms and discuss the differences between armed private contractors and conventional militaries, armed private contractors and mercenaries, and highlight the differences between private military companies and private security companies. I find several substantive distinctions, including recruitment and retainment, rent-seeking behavior and compliance with international regulations, and expected threat environment, respectively. Armed private contracting firms will continue to influence international security dynamics and necessitate further research and attention

Education for Sustainable Development- The Irish Construction Sector and the Need for a Sustainable Approach

This study explores the path to be taken towards achieving Sustainable Development. It examines the impact the construction industry has on the environment as a result of a knowledge and skills gap and considers how our present way of thinking facilitates this. It then goes on to show how a change in construction education can bring about change in the industry and facilitate the implementation of sustainable development. The study examines how the singular emphasis on technology, the introduction of the ‘expert’ into the domestic building process and the narrow focus on operational energy conservation raises questions about Ireland\u27s present path towards Sustainable Development. It will provide clear definitions for ‘sustainable building’. It will outline the significance of the \u27local\u27 and the ‘occupant’ in the sustainable building process. It will highlight conflicting sustainable philosophies and examines why the Irish construction industry has to go beyond Part L in order to align itself with Sustainable Development goals. In order to ensure the success of the drive towards a sustainable economy in Ireland it is imperative that societal change occurs. This study concentrates on the recently depleted Irish construction sector and the potential for a new direction in the industry based on a sustainable ecological approach. The following hypothesis is presented; that in order to ensure Sustainable Development a paradigm shift which forms the fundamental attitudes that we hold concerning the environment must take place. This paper will look at how higher level education may be the entry point where attitudes can be greatly influenced in parallel with the dissemination of knowledge and skills. While outlining why the construction industry must take a lead role in the change towards a sustainable economy this paper looks at how and why the educational process itself must also change in order to embed sustainable development, its philosophy and ethos in the construction sector
