Sustainable water use practices:understanding and awareness of masters level students

Present water consumption in the UK is unsustainable, with increasing societal and environmental pressures driving water stress. Personal use of water is a significant contributor to water demand and considering the number of universities and students in the UK the water use practices therein cannot be ignored. Therefore, this paper aims to deepen the theme of water consumption in the United Kingdom from the point of view of use practices for students. The originality in this research lies in better understanding whether UK Masters level students have a basic awareness of personal water consumption and water pricing and whether they have a preferred approach to reducing their water consumption—through a behavioral change, or through adoption of technolo-gies. Through use of a questionnaire approach applied to five cohorts (2017 to 2021) of Masters level students, the level of understanding and awareness towards their own domestic water use both now and in the future was demonstrated. Key findings suggest that Masters students underesti-mated their water use by 76% compared to the average UK national range and that there was an overall preference to adopt water saving technologies rather than changing user behavior (40% vs. 27%). The study concludes that it is important to approach water conservation from an SPT perspective in order to achieve meaningful change in water use practices. Qualitative and quantitative research is analyzed in light of theoretical models (i.e., Social Practice and Attitude Behavior Framework ABC) in order to make recommendations for greater societal prominence for this issue through media and education.</p

A resilience and environmentally sustainable assessment framework (RESAF) for domestic building materials in Saudi Arabia

In Saudi Arabia, the carbon footprint and energy use that results from using concrete in construction is a major negative contributor to the environmental effects of building materials. Likewise, the impact of annual cooling and heating energy demands has an equally prominent role to play. These demands need to be assessed and benchmarked in order that reduction targets can be set. Saudi Arabia presents its own unique context and local conditions, which creates a challenge when utilizing generic frameworks for assessing the environmental impact of domestic buildings. In meeting this aim, this paper presents a resilience and environmental sustainability assessment framework (RESAF) developed specifically for domestic buildings in Saudi Arabia. RESAF helps designers/builders to minimize the carbon footprint of the building fabric and reduce in-use energy demands of domestic buildings in Saudi Arabia. This paper shows how this framework can be used to reduce, by approximately 23%, the carbon impact from construction materials, primarily by substituting a portion of cement for pulverized fly ash (PFA) or ground granulated blast furnace slag (GGBS). A reduction of 19% in annual cooling and heating energy demand were additionally achieved throughout the building&rsquo;s life, simply by increasing insulation and using triple-glazed windows. The importance of passing these alternative solutions through the resilience filter is highlighted, not least questioning whether they are really fit-for-purpose
