The presented research aims to evaluate highly energy-efficient dwellings, in particular Passive Houses (PH), in Flanders and in The Netherlands, based on end-user experiences. In the introduction the definition of PH in the Benelux countries Belgium and The Netherlands is compared with the Nordic countries and certification and comfort issues...

In many countries, the characteristics of the electricity supply system are changing. Important developments that are unfolding in the electricity sector are (i) the growth of generation from renewable sources (PV, wind) that are less controllable than traditional power plants and that for a large part feed in into the distribution grids, and ...

Existing aeolian transport formulae tend to overestimate the sediment transport volumes in coastal environments. Supply limiting factors like moisture content, shell patches, sediment sorting, vegetation and morphological features are believed to explain these overestimations. These supply limitations act on a variety of spatio-temporal scales...

In this paper it is aimed to quantify bulk (surf-zone integrated) alongshore sediment transport using morphological data collected along the Dutch coast. The collected morphological data covers a domain of 18 km alongshore including the beach, the foreshore and the intertidal zone in the cross shore. The measurement domain contains the 20...

In order to understand how companies make investment decisions under conditions of deep uncertainty, we interviewed a number of actors in the Dutch electricity sector. Most of the economic literature that is devoted to this question is prescriptive in nature, describing rational methods to the investment decision process (such as real options...

In this paper, the aeolian transport model DUNE (Sauermann et al., 2001, Kroy et al., 2002) that describes important features and dynamics of typical desert dunes, is extended such that it can be applied in sandy coastal areas. Initial tests explore the limitations of the model in coastal areas after which adaptations are proposed and...

The coastal system consists of a sub-aqueous and a sub-aerial zone which can be separated by a border. At this border sediment exchange takes place from one zone to the other. This paper hypothesizes that conditions and therefore sediment exchange at this border are dependent on active profile characteristics. To analyze morphological...

Typically a beach is out of equilibrium after a nourishment is installed. To observe how a nourished beach behaves on the timescale of storms a monitoring campaign was set up at Vlugtenburg beach after a nourishment in the spring of 2009. Here we show a sediment budget analysis of the first 2.5 years for a coastal domain spanning 1750 m...

This paper presents a critical reflection of the evaluation of learning processes in organizations. Based on learning and evaluation theories and concepts we discuss qualitative and quantitative evaluation processes, and its relationship to short training sessions to foster sustainable development. Short training sessions solve barriers for...

The Houston - Galveston area is at significant risk from hurricane induced storm surges. This paper summarizes ongoing studies on flood risk reduction for the region. Firstly, based on a simplified probabilistic hurricane surge model , the return periods of surges within the bay have been estimated. This model framework can be used to assess the...

This paper describes the validation of the dune erosion model XBeach with laboratory measurement data of dune erosion in the presence of sea walls and revetments. Simulation results show that the essential dune set back processes are captured by the model and that the measurements at most locations are approximated quite well. Some aspects...

Students and staff of the minor ‘Management in a High-tech Context’ at Delft University of Technology reported a lack of integrated learning opportunities in the programme. The minor offered separate courses on financial management, human resource management, innovation, etc., but was not successful in integrating the different courses into a...

This paper describes the development of a rent index for Flanders, Belgium. This annual index, referred to as the huurprijsindex (rent index), is designed to detect changes in the rent of the overall stock of rental homes. We use the matched model methodology based upon repeat tenancy agreements, analogous to Case and Shiller’s geometric repeat...
