Richt Corona Safe Zones in, bepleiten Frank Suurenbroek en Gideon Spanjar, lector en onderzoeker bouwtransformatie aan de Hogeschool van Amsterdam. Dan kunnen ook kwetsbare mensen naar buiten.Hoewel de samenleving zich snel weer opent, is het virus onverminderd riskant voor onze 3,3 miljoen 65-plussers. Nu het aantal ic-opnames daalt, verdampt de tegenwoordigheid van geest om anderhalve meter afstand te houden. Voor ouderen en andere kwetsbare groepen is het cruciaal dat zij in hun eigen buurt veilig en ontspannen in de buitenlucht kunnen verblijven. [...]

NOVA coordinates a group of three inflatable mobile planetariums which visit around 200 primary and secondary schools per year (~30,000 students/year). After an initial stop in activities (March-June 2020) due to the COVID-19 crisis, NOVA restarted school visits in July 2020 using a high quality flat-screen. Since the start of the second peak of the COVID-19 pandemic in October 2020, the decision was made to suspend visits to secondary schools until at least the end of 2020. In late October and early November NOVA has performed extensive testing with a variety of online tools to continue to reach out to schools during the second wave of the pandemic in the Netherlands. In this article we describe the different platforms, discuss the technical considerations and report on the experiences with the first schools.

The Johan Cruijff ArenA (JC ArenA) is a big events location in Amsterdam, where national and international football matches, concerts and music festivals take place for up to 68,000 visitors. The JC ArenA is already one of the most sustainable, multi-functional stadia in the world and is realizing even more inspiring smart energy solutions for the venue, it’s visitors and neighbourhood. The JC ArenA presents a complex testbed for innovative energy services, with a consumption of electricity comparable to a district of 2700 households. Thanks to the 1 MWp solar installation on the roof of the venue, the JC ArenA already produces around 8% of the electricity it needs, the rest is by certified regional wind energy.Within the Seev4-City project the JC ArenA has invested in a 3 MW/2.8 MWh battery energy storage system, 14 EV charging stations and one V2G charging unit. The plan was to construct the 2.8 MWh battery with 148 2nd life electric car batteries, but at the moment of realisation there were not enough 2nd life EV batteries available, so 40% is 2nd life. The JC ArenA experienced compatibility issues installing a mix of new and second-life batteries. Balancing the second-life batteries with the new batteries proved far more difficult than expected because an older battery is acting different compared to new batteries.The EV-based battery energy storage system is unique in that it combines for the first time several applications and services in parallel. Main use is for grid services like Frequency Containment Reserve, along with peak shaving, back-up services, V2G support and optimization of PV integration. By integrating the solar panels, the energy storage system and the (bi-directional) EV chargers electric vehicles can power events and be charged with clean energy through the JC ArenA’s Energy Services. These and other experiences and results can serve as a development model for other stadiums worldwide and for use of 2nd life EV batteries.The results of the Seev4-City project are also given in three Key Performance Indicators (KPI): reduction of CO2-emission, increase of energy autonomy and reduction in peak demand. The results for the JC ArenA are summarised in the table below. The year 2017 is taken as reference, as most data is available for this year. The CO2 reductions are far above target thanks to the use of the battery energy storage system for FCR services, as this saves on the use of fossil energy by fossil power plants. Some smaller savings are by replacement of ICEby EV. Energy autonomy is increased by better spreading of the PV generated, over 6 instead of 4 of the 10 transformers of the JC ArenA, so less PV is going to the public grid. A peak reduction of 0.3 MW (10%) is possible by optimal use of the battery energy storage system during the main events with the highest electricity demand.

This report was produced within the framework of the RAAK PRP project ‘Veiligheid op de werkvloer’. Personal protective equipment (PPE) is used on a daily basis by millions of people all over the EU, voluntarily or as a result of EU legislation. In this report we deal specifically with the textile/garment aspects of PPE. In this context we must consider the fact that PPE encompasses a huge area with hundreds of different applications of materials and systems tuned to specific needs;from a materials point of view it represents a complex area due to the large diversity of labour conditions. Textiles and clothing represent an area where PPE is an important area of attention. On a global scale it is an area of much research. Safety and comfort are becoming more and more important and these aspects must be in balance. Uncomfortable systems will not be used and put safe working at risk. Thus there is a continuous need for technological innovation to improve the effectiveness of PPE systems. Specialization and specific combinations aimed at use under well-defined conditions contributes to finding a good balance between comfort and safety. The design of products, taking into account the individual needs represent an area of intensive research: Safety directed ‘fashion design’.The ultimate goal is the development of proactive systems by which workers (but capital goods as well) are optimally protected. There is also a lot of attention for maintenance and cleaning since protective functions may deteriorate as a result of cleaning processes. Another important point is standardization because producers need directions for product development and supply of goods. In our overview we make a distinction between static and dynamic systems. Static systems provide passive protection, simply by being a part of an equipment that separates the worker from the danger zone. Dynamic systems are more ‘intelligent’ because these can react to stimuli and subsequently can take action. These dynamic systems use sensors, communication technology and actuators. From this research the following may be concluded: 1. Safety is obtained by choice of materials for a textile construction, including the use of coatings with special properties, application of specific additives and he use of special designed fibre shapes. 2. The architecture and ultimate construction and the combinations with other materials result in products that respond adequately. This is of great importance because of the balance comfort – safety. But a lot can be improved in this respect. 3. Insight in human behaviour, ambient intelligence and systems technology will lead to new routes for product development and a more active approach and higher levels of safety on the work floor. Consequently there is a lot of research going on that is aimed at improved materials and systems. Also due to the enormous research area of smart textiles a lot of development is aimed at the integration of new technology for application in PPE. This results in complex products that enhance both passive and active safety. Especially the commissioners, government and industry, must pay a lot of attention to specifying the required properties that a product should meet under the specific conditions. This has a cost aspect as well because production volumes are usually not that large if for small groups of products specific demands are defined. We expect that through the technology that is being developed in the scope of mass customization production technologies will be developed that allows production at acceptable cost, but still aimed at products that have specific properties for unique application areas. Purchasing is now being practiced through large procurements. We must than consider the fact that specification takes place on the basis of functionality. In that case we should move away from the current cost focus but the attention should shift towards the life cycle

Context When the pandemic hit the world, teachers were forced to change their education from onsite to virtual overnight Understandably, teaching quality decreased in the beginning, as there was little experience in how to adapt the educational design Zuyd University of Applied Sciences ( recognized the problem that teachers were on different didactic and pedagogical levels when it comes to online education Unfortunately, the pandemic made it hard for teachers to connect with each other In the Domain of Health and Welfare, this led to the idea of establishing a professional learning community A professional learning community ( can be seen as an informal group of people who share knowledge and experiences among each other on a common topic they are all highly interested in Zuyd’s vision “passion for development” sets a good basis for the start of such a community. Steps we took In order to find out how a professional learning community can look like in Zuyd, the following steps were taken Firstly, we collected and evaluated literature and best practices around the topic Based on our findings we developed an interview guideline and conducted interviews with eight teachers from the Domain of Health and Welfare Throughout the whole report a SWOT analysis was performed with the literature and best practices filling opportunities and threats and the interviews providing content for strengths and weaknesses Main findings From these sources, we derived enablers for a successful learning community, which led to recommendations for Zuyd on how to strategically position, implement and organize a PLC One of our major recommendations is to make didactic and pedagogical skills an important topic within Zuyd in order to strategically implement the learning community into Zuyd’s strategy Furthermore, we recommend giving the lead in organizing and facilitating the PLC to the blended learning task force To collect a diverse set of interested employees to the core group, the educational managers should personally approach teachers that might be interested The sense of urgency around the topic needs to be addressed regularly through the directors of the Domain, the task force of blended learning, as well as the PLC itself In this way, interest in the topic of didactic and pedagogical skills and blended learning can be enhanced In the report we go into greater detail on how to organize and apply these recommendations. We are convinced that implementing these steps will pay off in the future and will successfully enhance competencies on blended learning and didactic and pedagogical skills through knowledge exchange.
