Bohm, N.L. (author), Hoekstra, M.J. (author), van den Burg, L.P.J. (author), Reincke, M.M.O. (author)In this case study, we answer the question: what are design characteristics for a personal development line integrated in undergraduate engineering curricula? We investigated the development of such a line in a Bachelor of Architecture, Urbanism and Building Sciences in The Netherlands. We documented and analysed the preparation of and...conference paper 2023

Croon, T.M. (author), Hoekstra, J.S.C.M. (author), Dubois, Ute (author)This report addresses energy poverty in social housing, proposing solutions to aid an inclusive energy transition. It highlights the disproportionate impact of rising prices on vulnerable tenants, suggesting short-term measures like energy advice and energy-saving kits, along with long-term strategies such as prioritising renovations for those...report 2023

Croon, T.M. (author), Hoekstra, J.S.C.M. (author), Elsinga, M.G. (author), Dalla Longa, F. (author), Mulder, Peter (author)Recent energy price spikes have led to increased energy poverty among low-income households living in inefficient homes. Accurate statistics on energy poverty help inform resource allocation and better target relief schemes and retrofit funds. Existing indicators are predominantly defined in terms of a headcount ratio – the share of population...journal article 2023

Croon, T.M. (author), Hoekstra, J.S.C.M. (author), Dubois, U. (author)Since energy prices across Europe started to rise in 2021, there has been growing concern of social housing tenants at risk of energy poverty. So far, studies have largely focused on the role of governments and on what tenants themselves could do. However, research has rarely considered specific targeting approaches by social housing providers ...abstract 2023

Stefanie Horian, S.H. (author), Qian, QK (author), Hoekstra, J.S.C.M. (author), Visscher, H.J. (author)Energy efficiency renovation (EER) of the existing residential housing stock is crucial to achieving further decarbonization to be climate neutral by 2050. This transition is particularly challenging for affordable rental housing providers as they have to make intensive investment decisions while balancing rental affordability for their low- and...abstract 2023

Hoekstra, J.S.C.M. (author), Gentili, M. (author)In recent years, the housing market of Amsterdam, traditionally known for its large share of social rental dwellings, experienced a trend of commodification and financialization. Due to its central position and good facilities, the Dutch capital has become very popular among both home seekers and investors.conference paper 2023

Croon, T.M. (author), Hoekstra, J.S.C.M. (author), Dubois, Ute (author)The European energy crisis of 2022 stresses the importance of protecting the most vulnerable households. Price peaks disproportionally affect households with low incomes, limited savings, and inefficient homes, and increased energy poverty: the inability to secure sufficient domestic energy services that allow for participation in society ...conference paper 2023

(author), Kostopoulos, Vassilios (author)Unmanned Aircraft Systems (UAS) Traffic Management (UTM) is an active research subject as its proposed applications are increasing. UTM aims to enable a variety of UAS operations, including package delivery, infrastructure inspection, and emergency missions. That creates the need for extensive research on how to incorporate such traffic, as...journal article 2023

(author), Patrinopoulou, Niki (author), Daramouskas, Ioannis (author), Ellerbroek, Joost (author), Lappas, Vaios (author), Kostopoulos, Vassilios (author), Hoekstra, J.M. (author)The interest in urban air mobility as a potential solution for urban congestion is steadily growing. Air operations in urban areas can present added complexity as compared with traditional air traffic management. As a result, it is necessary to test and develop novel airspace designs and rules. As airspace in urban areas is a scarce resource,...journal article 2023

Doole, M.M. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Package delivery via autonomous drones is often presumed to hold commercial and societal value when applied to urban environments. However, to realise the benefits, the challenge of safely managing high traffic densities of drones in heavily constrained urban spaces needs to be addressed. This paper applies the principles of traffic segmentation...journal article 2022
