Light therapy is applied as treatment for a variety of problems related to health and ageing, including dementia. Light therapy is administered via light boxes, light showers, and ambient bright light using ceiling-mounted luminaires. Long-term care facilities are currently installing dynamic lighting systems with the aim to improve the well-being of residents with dementia and to decrease behavioural symptoms. The aim of this chapter is to provide an overview of the application of ceiling-mounted dynamic lighting systems as a part of intelligent home automation systems found in healthcare facilities. Examples of such systems are provided and their implementation in practice is discussed. The available, though limited, knowledge has not yet been converted into widespread implementable lighting solutions, and the solutions available are often technologically unsophisticated and poorly evaluated from the perspective of end-users. New validated approaches to the design and application of ambient bright light are needed.
Long-term care facilities are currently installing dynamic lighting systems with the aim to improve the well-being and behaviour of residents with dementia. The aim of this study was to investigate the implementation of dynamic lighting systems from the perspective of stakeholders and the performance of the technology. Therefore, a questionnaire survey was conducted with the management and care professionals of six care facilities. Moreover, light measurements were conducted in order to describe the exposure of residents to lighting. The results showed that the main reason for purchasing dynamic lighting systems lied in the assumption that the well-being and day/night rhythmicity of residents could be improved. The majority of care professionals were not aware of the reasons why dynamic lighting systems were installed. Despite positive subjective ratings of the dynamic lighting systems, no data were collected by the organizations to evaluate the effectiveness of the lighting. Although the care professionals stated that they did not see any large positive effects of the dynamic lighting systems on the residents and their own work situation, the majority appreciated the dynamic lighting systems more than the old situation. The light values measured in the care facilities did not exceed the minimum threshold values reported in the literature. Therefore, it seems illogical that the dynamic lighting systems installed in the researched care facilities will have any positive health effects.
Humidification is not a common procedure in many buildings in the Netherlands. An exception are buildings used for healthcare, especially hospitals. There, e.g. in operating theatres, relative humidity (RH) generally is controlled stringently at levels around 50%. From an energy point-of-view humidification is an energy-intensive activity. Currently, more than 10% of the total energy used in healthcare buildings is spent on humidification. The basis for an RH of around 50%, however, is not clear. Therefore, we pursued a scoping review to find evidence for specific RH thresholds in such facilities. In addition, an inventory was made of the current practice in the Netherlands. After analyzing the title and abstracts, the remaining references were read by two persons and scored on several topics. Guidelines and current practice were analyzed by referring to existing (inter)national guidelines and standards, and by contacting experts from Dutch hospitals through a survey and semi-structured interviews. Outcomes from the literature review were grouped into four different topics: 1) micro-organisms and viruses, 2) medical devices, 3) human physiology and 4) perception. No scientific evidence was found for the currently generally applied RH set-point of ~50%. Some studies suggest a minimum RH of 30% but the evidence is weak, with exception of medical devices if specifications require it. A lack of research that addresses more long-term exposure (a couple of days) and includes frail subjects, is noted. It was found that RH requirements are strictly followed in all hospitals consulted, some only focusing on the hot zones, but in many cases extended to the whole hospital. Steam humidification is mostly applied for hygienic reasons. but is quite energy-intensive. The conclusion t is that there is no solid evidence to support the RH-setpoints as currently applied in the Netherlands. It merely appears a code of practice. Therefore, there appears room for quick and significant energy savings, and CO2 emission reductions, when considering control at lower RH values or refraining from humidification at all, while still fulfilling the indoor environment requirements and not negatively influencing the health risk. This outcome can be applied directly in current practice with the available techniques.

Aeres University of Applied Sciences has placed internationalisation as a key driver in its overall strategy. By prioritising the internationalisation of education and educational consultancy the university has created solid opportunities for students, lecturers, and partners at regional, national, and international levels. Currently, more strategic development on internationalisation in applied research at Aeres is needed. There is an opportunity to utilise highly proficient researchers, state-of-the-art facilities, and an impressive national research portfolio, and for this, there is a need to develop international research agenda, a key priority for AeresResearch4EU. To address this need, Aeres University of Applied Sciences aims to strengthen its internationalisation efforts with its research activities, opening the door to many opportunities, and most importantly, creating an international research agenda spanning the university's three locations. The main objectives of AeresResearch4EU are to analyse the existing research strategy and professorships and develop them towards a global research agenda for the European Union. By focusing on international research projects, Aeres can further enhance its reputation as a leading institution for applied research in agriculture, food, environment, and green technologies. AeresResearch4EU aims to create new partnerships and collaborations with researchers and institutions across Europe, allowing Aeres to contribute to developing innovative and sustainable solutions to global challenges. With its strong commitment to internationalisation and its focus on applied research, Aeres University of Applied Sciences is poised to become an essential player in the European research landscape.
Goal: In 2030 the availability of high quality and fit-for-purpose recycled plastics has been significantly increased by implementation of InReP’s main result: Development of technologies in sorting, mechanical and chemical recycling that make high quality recycled plastics available for the two dominating polymer types; polyolefins (PE/PP) and PET. Results: Our integrated approach in the recycling of plastics will result in systemic (R1) and technological solutions for sorting & washing of plastic waste (R2), mechanical (R3) and chemical recycling (R4, R6) and upcycling (R5, R7) of polyolefins (PE & PP) and polyesters (PET). The obtained knowledge on the production of high quality recycled plastics can easily be transferred to the recycling of other plastic waste streams. Furthermore, our project aims to progress several processes (optimized sorting and washing, mechanical recycling of PP/PE, glycolysis of PET, naphtha from PP/PE and preparation of valuable monomers from PP/PET) to prototype and/or improved performance at existing pilot facilities. Our initiative will boost the attractiveness of recycling, contribute to the circular transition (technical, social, economic), increase the competitiveness of companies involved within the consortium and encourage academic research and education within this field.
BCLivinglab combines the supply chain and logistics physical infrastructure of training centres (ROCs), research institutes and companies throughout the Netherlands, with the expertise and virtual infrastructure of blockchain specialists from BlockLab. Companies, especially SMEs, in supply chain and logistics will use this unique combination of physical facilities and the expert network to experiment with and develop blockchain applications. BCLivinglab is easily accessible for companies, due to its close proximity (distributed facilities) and low threshold procedures. It will make blockchain technology accessible for companies, thus supporting innovation and improving the competitive advantage of the Dutch supply chain and logistics sector.
