Lebanon’s economic crisis has disrupted the country’s energy and water sectors, highlighting their interdependence. The methodologyinvolves surveying 150 municipalities across all Lebanese governorates, ensuring a comprehensive coverage of public and private waterresources. Data on water and energy were collected before and during the crisis to explore this nexus during periods of economic turmoil.The findings reveal a decline in water provision during the crisis, with the average weekly water supply plummeting from 49 h in 2019 to 22 hin 2023. Concurrently, the use of water tankers has surged from 26 to 44%, indicating a concerning shift in water acquisition methods.Despite the crisis, conventional water sources remain predominant, while unconventional sources account for less than 1% of the totalsupply. In response to the energy shortage, renewable energy sources have gained traction in residential, commercial, and industrial sectors.The scarcity and rising cost of electricity have driven the adoption of solar photovoltaics in the water sector, reaching 4.8% for extraction fromunderground reservoirs and 2.8% for distribution. Similarly, the use of solar water heaters has increased from 7.9 to 15.4% in 2023. Thesefindings underscore the interplay between energy and water security during periods of economic instability.

Energy efficiency has gained a lot of prominence in recent debates on urban sustainability and housing policy due to its potential consequences for climate change. At the local, national and also international level, there are numerous initiatives to promote energy savings and the use of renewable energy to reduce the environmental burden. There is a lot of literature on energy saving and other forms of energy efficiency in housing. However, how to bring this forward in the management of individual housing organisations is not often internationally explored. An international research project has been carried out to find the answers on management questions of housing organisations regarding energy efficiency. Eleven countries have been included in this study: Germany, the United Kingdom (more specifically: England), France, Sweden, Denmark, the Netherlands, Switzerland, Slovenia, the Czech Republic, Austria and Canada. The state of the art of energy efficiency in the housing management of non-profit housing organisations and the embedding of energy efficiency to improve the quality and performance of housing in management practices have been investigated, with a focus on how policy ambitions about energy efficiency are brought forward in investment decisions at the estate level. This paper presents the conclusions of the research

This study investigates the degree of news avoidance during the first months of the Covid-19 pandemic in the Netherlands. Based on two panel surveys conducted in the period April–June 2020, this study shows that the increased presence of this behavior, can be explained by negative emotions and feelings the news causes by citizens. Moreover, news avoidance indeed has a positive effect on perceived well-being. These findings point to an acting balance for individual news consumers. In a pandemic such as Covid-19 news consumers need to be informed, but avoiding news is sometimes necessary to stay mentally healthy.

The growing energy demand and environmental impact of traditional sources highlight the need for sustainable solutions. Hydrogen produced through water electrolysis, is a flexible and clean energy carrier capable of addressing large-electricity storage needs of the renewable but intermittent energy sources. Among various technologies, Proton Exchange Membrane Water Electrolysis (PEMWE) stands out for its efficiency and rapid response, making it ideal for grid stabilization. In its core, PEMWEs are composed of membrane electrode assemblies (MEA), which consist of a proton-conducting membrane sandwiched between two catalyst-coated electrodes, forming a single PEMWE cell unit. Despite the high efficiency and low emissions, a principal drawback of PEMWE is the capital cost due to high loading of precious metal catalysts and protective coatings. Traditional MEA catalyst coating methods are complex, inefficient, and costly to scale. To circumvent these challenges, VSParticle developed a technology for nanoparticle film production using spark ablation, which generates nanoparticles through high-voltage discharges between electrodes followed by an impaction printing module. However, the absence of liquids poses challenges, such as integrating polymeric solutions (e.g., Nafion®) for uniform, thicker catalyst coatings. Electrohydrodynamic atomization (EHDA) stands out as a promising technique thanks to its strong electric fields used to generate micro- and nanometric droplets with a narrow size distribution. Co-axial EHDA, a variation of this technique, utilizes two concentric needles to spray different fluids simultaneously.The ESPRESSO-NANO project combines co-axial EHDA with spark ablation to improve catalyst uniformity and performance at the nanometer scale by integrating electrosprayed ionomer nanoparticles with dry metal nanoparticles, ensuring better distribution of the catalyst within the nanoporous layer. This novel approach streamlines numerous steps in traditional synthesis and electrocatalyst film production which will address material waste and energy consumption, while simultaneously improve the electrochemical efficiency of PEMWEs, offering a sustainable solution to the global energy crisis.
Door COVID-19 crisis zijn er extra uitdagingen om de verdere doorontwikkeling van het praktijkgerichte onderzoek en de onderliggende infrastructuur en professionalisering kwalitatief en kwantitatief te realiseren. De Hogeschool van Arnhem en Nijmegen (HAN) zet de IMPULS 2020 middelen in om de rol van het praktijkgericht onderzoek hierin te bestendigen en versterken. Het betreft een academie overstijgende aanvraag. Het beschikbare budget vanuit de regeling bedraagt 550.000 euro en zal in 2021 via twee lijnen worden ingezet: 1. Netwerk- en visievorming Dit richt zich op de versterking van de strategische netwerkvorming en samenhang overstijgend aan de zwaartepunten als focus gebieden voor de samenwerking onderwijs, onderzoek en werkveld (deels is hier aandacht voor de ontwikkeling en samenwerking bij regelingen als SPRONG of MMIP). Dit moet leiden tot het ontwikkelen van een meerjarige roadmap SLIM, SCHOON & SOCIAAL (S3). De regie ligt bij dit deel bij het zwaartepunt management. (Sustainable Energy & Environment (SEE), Smart Region en Health). 2. Professionalisering onderzoeksondersteuning Dit gedeelte betreft het vervolg op het project professionalisering onderzoeksondersteuning en richt zich (in lijn met het nationale project DCC) op de doorontwikkeling van: datastewardship, FAIR data & open access, ICT kennisinfrastructuur en communicatie rondom onderzoek en ondersteuning, verdere ontwikkeling van een Open Science Platform en voorbereiding op een HAN Open Access Fonds.

Cities, the living place of 75% of European population, are crucial for sustainable transition in a just society. Therefore, the EU has launched a Mission for 100 Climate-Neutral Smart Cities (100CNSC). Construction is a key industry in making cities more sustainable. Currently, construction consumes 50% resources, uses 40% energy, and emits 36% greenhouse gasses. The sector is not cost-efficient, not human-friendly, and not healthy – it is negatively known for “3D: dirty, dangerous, demanding”. As such, the construction sector is not attractive for educated and skilled young professionals that are needed for the sustainable transition and for resolving the housing crisis. In contrast with the non-circular designs, materials and techniques that are still common in the construction industry, some other industries and fields have cultivated higher standards for sustainable products, especially in clean and efficient assembly and disassembly. Examples can be found in the maritime and off-shore industry, smart manufacturing, small electronics, and retail. The Hague University of Applied Sciences (THUAS) aims to become the leader of a strong European consortium for preliminary research to develop knowledge that is needed for the upcoming Horizon Europe proposal (within Cluster 4, Destination 1 - Re-manufacturing and De-manufacturing technologies) in relation with the EU Mission 100CNSC. The goals of this preliminary research are: (a) to articulate new concepts that will become an input for a new research proposal and (b) to organize a high-quality European consortium with high-quality partners for a lasting collaboration. This preliminary research project focuses on the question: How can the construction sector adopt and adapt the best practices in assembly and disassembly from other industries –including maritime, manufacturing and retails– in order to enhance circular urban construction and renovation with an active involvement of educated and skilled young professionals?
