Practicing learning and learning in practice: Testing learning tools for energy demand side management projects

The history of energy demand side management (DSM) projects shows that accomplishing lasting energy-behavioural changes is difficult. The CHANGING BEHAVIOUR project aims at a better understanding of energy-related behavioural change, in order to improve the DSM practice. The approach is one of continuous interaction between researchers and...

Insights in using home energy management systems

In an ongoing process, three diverse Home energy management systems (HEMS) have been implemented in the households in the Netherlands. Through a series of questionnaires, interviews, focus groups and usability tests, a wide range of knowledge in being gathered. Because of this broad approach, the insights that are gained are not only limited to...

Reducing drying energy and costs by process alterations at aggregate stockpiles

In the field of bulk solids, handling knowledge on moisture behaviour in aggregate stockpiles can be useful for process optimisation in terms of energy consumption. In the asphalt industry, an increase in moisture content leads to a significant increase in energy consumption. To determine the characteristics of moisture behaviour, correlations...

Optimizing Pneumatics: The design and introduction of a new energy saving system

This report explains the creative journey made by a strategic product designer developing a new energy saving system and its market introduction. In short, the assignment was to design and optimize the components needed in a new energy saving concept, already partly conceptualised by the company Q Plus. Starting with only a raw first idea, my...

Reducing drying energy and costs by process alterations at aggregate stockpiles

Quality assurance for passive houses

For newly built houses national ambitions prescribe increasing levels of energy performances, even including achieving net zero energy or carbon neutral houses. This is in large contrast with the lack of quality in many building processes. The building regulations, processes and control will have to be reshaped to support these ambitions, taking...

Development of District Heating Networks in Urban Areas

The development of district heating networks in urban areas descibes an approach to achieve the goals and targets for energy saving, reduction of CO2-emissions and sustainbale energy that are stated by the government. For the development of district heating networks energy conversion systems are used of generating heat and networks are used to...

Feasibility, beneficiality, and institutional compatibility of a micro-CHP virtual power plant in the Netherlands

Dutch households are responsible for a significant part of the total Dutch energy consumption and CO2 emissions. One option for decreasing household energy consumption and CO2 emissions is to deploy micro-combined-heat-power (?CHP) units. A micro-CHP virtual power plant (VPP) is a cluster of grid connected ?CHP units that is monitored and...

A structured approach to heat exchanger network retrofit design

Process plants have high energy consumption. Much energy can be saved by a proper design of the heat exchanger network, which contains the main heat transferring equipment of the plant. Existing plants can often be made more energy-efficient by a retrofit: the (physical) modification of the equipment and piping in the heat exchanger network....

Het ontwerp van intelligente software voor energiebezuiniging met behulp van patroonherkenning in het elektriciteitsverbruik

This thesis presents software that controls electrical household appliances. It uses an intelligent algorithm that adapts to the use of these household appliances by recognizing patterns of electricity useage.

Designing a lean energy process for resin production, by alternative treatment of process water using freeze concentration or direct vapour incineration
