The purpose of this study is to show how local authorities (municipalities) deal with their community real estate. The study is an annually recurring research: every year since 2008 (except for 2013), Dutch municipalities have been asked to complete a questionnaire about how they manage their real estate. With these results it is possible to perform quantitative analyses on both trends and the current situation. The questionnaire responses have led to the following conclusions: (1) Half of the municipalities has a policy but takes few risk measures, (2) Withdrawing local government, (3) Management and operations most outsourced tasks, (4) Obstacles remain unchanged, (5) Cost reduction most relevant policy theme since 2009, (6) Relevance of some policy themes depends on municipality size, (7) More real estate is offered, smaller percentage is sold, 8) More FTEs for real estate management, especially executive tasks and (9) Conscious focus on quality. Dutch municipalities tune their new developments of the municipal real estate policy to the results of the Barometer for Municipal Community Real Estate. This leads to a further development of professionalism of the municipal real estate portfolios. The contribution to science is showing patterns of community real estate management at Dutch municipalities. A longitudinal study of this size on this subject is unique in The Netherlands.

This study was presented at the Bled eConference and received the Outstanding Paper Award. The study examines how two organizational aspects, Transformational Leadership and Employee Empowerment contribute to companies harnessing their Data Analytic Capability to develop a Data Driven Culture. The findings of a cross-sectional survey design show that Transformational Leadership compounds the positive effect of Data Analytic Capability on Data Driven Culture.
A smart charging profile was implemented on 39 public charging stations in Amsterdam on which the current level available for electric vehicle (EV) charging was limited during peak hours on the electricity grid (07:00-08:30 and 17:00-20:00) and was increased during the rest of the day. The impact of this profile was measured on three indicators: average charging power, amount of transferred energy and share of positively and negatively affected sessions. The results are distinguished for different categories of electric vehicles with different charging characteristics (number of phases and maximum current). The results depend heavily on this categorisation and are a realistic measurement of the impact of smart charging under real world conditions. The average charging power increased as a result of the new profile and a reduction in the amount of transferred energy was detected during the evening hours, causing outstanding demand which was solved at an accelerated rate after limitations were lifted. For the whole population, 4% of the sessions were positively affected (charged a larger volume of energy) and 5% were negatively affected. These numbers are dominated by the large share of plug-in hybrid electric vehicles (PHEVs) in Amsterdam which are technically not able to profit from the higher current levels. For new generation electric vehicles, 14% of the sessions were positively affected and the percentage of negatively affected sessions was 5%.
Epoxy thermosets are extensively used as coatings, adhesives and in structural applications as they typically impart outstanding mechanical and electrical properties as well as chemical resistance. The currently used epoxy thermosets are produced from fossil-based non-recyclable materials. To be able to meet the circularity and sustainability goals set by the EU, this needs to change. Biobased epoxy thermosets from residual streams are considered a promising and urgently needed alternative to regular epoxy thermosets. The Cashew Nut industry could play a significant role in the development of these biobased epoxy thermosets. Global cashew nut production is about 4 million tons/year. The cashew nutshell is currently discarded as waste or used as an inefficient fuel, creating environmental issues. The cashew nutshell contains Cashew Nutshell Liquid (CNSL), which consists of the valuable chemical component cardanol. Cardanol can be used to produce biobased epoxy thermosets with balanced rigid-flexible performance. However, systematic studies about the production, properties, recyclability and commercial opportunities of the cardanol based epoxy thermosets are lacking. In this project consortium partners Avans, RUAS, Maastricht University, TU/e, Nuts2, Charcotec, NPSP, SABA, and Prokol jointly aim to answer the question: How can we develop sustainable and economically viable biobased epoxy thermosets and composites from cashew nutshell residue? First the pyrolysis process will be optimized for the effective production of CNSL. Next, the cardanol in the CNSL will be purified and modified to make the recyclable biobased epoxy thermoset. Finally, by adding biocarbon (which is also produced during the pyrolysis of cashew nutshell) to the biobased epoxy thermoset, a composite with enhanced mechanical, electrical, and thermal properties is expected to be obtained. The success of this project serves as a catalyst for the development of sustainable solutions in the thermoset industry and contribute to a sustainable application of cashew nut residue.
