This paper investigates the relationship between self-build housing and the wider planning and housing regime. Although there is growing policy and academic attention to self-build housing, there is a lack of understanding of the institutional and regulatory conditions shaping the prospects of such housing provision. This paper takes the case of The Netherlands and scrutinizes how institutional dynamics over time have made lower and middle residents dependent on densely organized consortia of municipalities, housing associations and developers. These norms of land development appear to be at odds with the logic of self-building. Through exploring evidence in a pilot study of a municipal self-building scheme in Almere, the authors suggest that making self-building the cornerstone of a resident-led land development strategy, also for low- and middle-incomes, implies a reconfiguration of the actors’ positions in housing provision. This entails a commissioning role for residents in the institutional domain of social and commercial developers.

The aim of this research is to assess the potential impact of the CO2 Performance Ladder on CO2 emission reduction. The CO2 Performance Ladder is a new green procurement scheme that has been adopted by several public authorities in the Netherlands; it is a staged certification scheme for energy and CO2 management. The achieved certification level gives companies a certain competitive advantage in contract awarding procedures. While the scheme has been widely adopted by companies in the construction industry, other types of companies in the supply chain of the commissioning parties also participate. Currently, more than 190 companies participate in the scheme. The aggregate CO2 emissions covered by the scheme are around 1.7 Mtonnes, which corresponds to almost 1 % of national greenhouse gas emissions in the Netherlands. Since the introduction of the scheme the total CO2 emissions have decreased substantially. Nevertheless, these emission reductions should be interpreted with caution since emission reductions are dominated by a few companies and are affected to a large extent by economic activity. Companies participating in the scheme have set different types of CO2 emission reduction targets with varying ambition levels. The projected impact of these targets on CO2 emissions is in the range of a 0.5 %-1.3 % absolute emission reduction per year, with a most likely value of 1.1 %. The CO2 Performance Ladder can therefore make a substantial contribution to achieving the CO2 emission reductions for non-ETS sectors in the Netherlands up to 2020.

Electrification of transportation, communication, working and living continues worldwide. Televisions, telephones, servers are an important part of everyday life. These loads and most sustainable sources as well, have one thing in common: Direct Current. The Dutch research and educational programme ‘DC – road to its full potential’ studies the impact of feeding these appliances from a DC grid. An improvement in energy efficiency is expected, other benefits are unknown and practical considerations are needed to come to a proper comparison with an AC grid. This paper starts with a brief introduction of the programme and its first stages. These stages encompass firstly the commissioning, selection and implementation of a safe and user friendly testing facility, to compare performance of domestic appliances when powered with AC and DC. Secondly, the relationship between the DC-testing facility and existing modeling and simulation assignments is explained. Thirdly, first results are discussed in a broad sense. An improved energy efficiency of 3% to 5% is already demonstrated for domestic appliances. That opens up questions for the performance of a domestic DC system as a whole. The paper then ends with proposed minor changes in the programme and guidelines for future projects. These changes encompass further studying of domestic appliances for product-development purposes, leaving less means for new and costly high-power testing facilities. Possible gains are 1) material and component savings 2) simpler and cheaper exteriors 3) stable and safe in-house infrastructure 4) whilst combined with local sustainable generation. That is the road ahead. 10.1109/DUE.2014.6827758

In this project, a consortium of Fraunhofer Innovation Platform (FIP-AM@UT), Connec2 and Walraven will investigate the possibility of two-way communication between production machines and an XR (eXtended Reality) platform. This communication can benefit the installation, commissioning and maintenance of specialty machines by connecting remote experts to local technicians and the machine in a virtual environment. This can reduce the necessity for travelling of remote experts (machine builders, programmers, process engineers), which leads to faster respond times and improves the well-being of these experts. Through the XR platform of Connec2, which is already used in the market for online meetings, presentations and collaboration, we can enable monitoring as well as (managed) control of a machine. For this we need to extend the production machine control with an interface that allows for remote connections. Special attention will be given to the safety and security aspects of the system. At all times, the machine should be safe for its direct users and surrounding. Things like loss of connectivity or network latency may not lead to dangerous situations. Another thread to the safety of the machine might be unauthorized access to the system. A secure system design will have to prevent this. The project not only aims to design such a system, but also to create a demonstrator of the development. Cooperation between local and remote users of a machine can be tested and validated at the shopfloor of the Advanced Manufacturing Center, a fieldlab for innovating digital production techniques.
