The application of reusable hollow core slab connections in steel frames: Investigating the behaviour of a newly proposed reusable connection with increased tolerances

To align with the objective of the European Green Deal [46] policy of achieving net-zero greenhouse gas emissions by 2050, the construction sector must transition to a circular built environment. Most of the waste in the Netherlands is related to construction and demolition waste, with the industry accounting for approximately 35% of CO<sub>2<...

A justified decision or a justified symbolic process: Exploring the Relationship Between Procedural Policy Tools, Stakeholder Conflict and Multi-Level Decision-Making in Dutch Infrastructure cases

Policy making and the decision-making process has developed over the past decades to include more (scientific) evidence to support policy construction, such as the Cost-benefit Analysis or Environmental Impact Analysis. However, depending on the perspective of the policymaker as well as the evaluator, successful policies outcomes may be...

Application of Sentinel-1 data to quantify Arctic Coastal Retreat

In the arctic region many coastal areas exhibit rapid erosion, with coastal retreat or erosion rates of 10 meters per year (m/yr.) or higher in places. This poses a threat primarily to all manner of infrastructure built directly on and near the coastline. With climate change the coastal erosion is expected to increase. This effect is expected to...

Circularity in the structural design: The implementation of circular design alternatives for the load-bearing structure in the preliminary design phase

Politicians, scientific researchers and companies all know; the transition to a Circular Economy [CE] should start now, or actually should have started yesterday. The CE is an economic system that replaces the current take-make-waste linear system and replaces this with the reduction, reuse and recovering of resources. The challenge is to build...

Washing as a Service - Quantifying the Environmental Impact of a pay-per-use washing machine through Life Cycle Assessment

In order to live more sustainably on this planet, the world’s population needs to transform the current take-make dispose society towards a society with more maintainable consumption patterns and more sustainable business models. A way to achieve this, is a circular economy in which value is maintained within the product cycle, by sharing,...

Structural sustainability in the early design phase: A parametric environmental impact assessment of various construction materials, including the design for deconstruction and donor structural framework concepts

The Netherlands is currently in the process of transitioning from a linear economy to a circular economy, in accordance with the ”Nederland Circulair 2050” policy. To increase the circularity of buildings, several approaches can be integrated. In this research, the so-called Design for Deconstruction and Donor Structural Framework concepts are...

Comparison between a bottom-up and a top-down approach for the compilation of environmental extensions for the Multi-Region Input-Output database EUREGIO

In this thesis two different approaches for the construction of environmental extensions compatible with the MRIO database EUREGIO are compared alongside with the latest liter- ature on consumption-based accounts. To date, few studies have focused on the provision of sub-national accounts at the NUTS2 level of detail and never production-based...

Digital construction: Parametric structural & environmental design of a 3D printed concrete bridge

The objective of this research project is to verify whether 3D printing of concrete (3DPC) reduces the environmental impact by increasing the structural efficiency. During the literature study, numerous articles were identified that claimed an increase of structural efficiency by using 3DPC to reduce material use. Some of these articles suggest...

Improving Flood Safety and Ferry Navigation in the Changing Environment of Holwerd

Relative sea level rise and climate change represent long-term threats for the ecosystems and flood defence system in the Wadden Sea. Moreover, the flood-dominant tidal basins in the area lead to sedimentation in the navigational channels used by the ferry services that connect the mainland to the Dutch Wadden islands. This report provides flood...
