Waste heat recovery is essential to reduce energy consumption in industry. A heat pump can be used to upgrade waste heat to a temperature level that is suitable for process heat. This study concerns a compression-resorption heat pump. The goal is to optimise the heat pump energetically, while keeping the investment attractive. Entropy production...

The last step in the production of milk powder is drying, a very energy intensive process that demands 30% to 40% of the total energy input of a typical plant. It takes place in Spray Dryers (SD), where concentrated milk is sprayed and placed in direct contact with hot and dry air that cools down and gains humidity as water is evaporated from...

Energy reduction has been on the political agenda since the last couple of decades. One of the most common policies to reduce energy consumption has been improving efficiency. However, the phenomenon called the rebound effect may threaten the effectiveness of policies aiming to reduce consumption by improving efficiency. The rebound effect is...

The building envelope is the interface between the interior of the building and the outdoor environment. A building's energy consumption to a large extent depends on certain envelope design elements. As a consequence, for achieving high levels of energy-saving in buildings, design measures with high impact should be firstly defined and then...

The Airey building blocks in Amsterdam currently don’t meet regulations set for 2020 that state that buildings should operate in an energy neutral manner. The goal of this research is to establish whether addition of greenhouses can improve indoor thermal comfort and reduce total energy use in such a way that they contribute to energy neutrality...

Zero Energy Buildings intend to contribute to a more sustainable world. They approach this problem by reducing energy consumption and generating renewable energy. The considerations that should be taken into account for the design of these type of buildings in low latitudes are explored in the present research.

The existing housing stock plays a major role in meeting the energy efficiency targets set in EU member states such as the Netherlands. The non-profit housing sector in this country dominates the housing market as it represents 31% of the total housing stock. The focus of this paper is to examine the energy efficiency measures that are currently...

A dynamic building stock model is applied to simulate the development of dwelling stocks in 11 European countries, over half of all European dwellings, between 1900 and 2050. The model uses time series of population and number of persons per dwelling, as well as demolition and renovation probability functions that have been derived for each...

Energy efficiency in building heating, ventilating and air conditioning (HVAC) equipment requires the development of accurate models for testing HVAC control strategies and corresponding energy consumption. In order to make the HVAC control synthesis computationally affordable, such control-oriented models are typically a simplified version...

Our present economy is high-energy and demand-intensive, demand met through the use of high energy yield fossil fuels. Energy efficiency and renewable energy sources are proposed as the solution and named the ‘twin pillars’ of sustainable energy policy. Increasing energy efficiencies are expected to reduce energy demand and fossil fuel use and...

Now that it becomes obvious that disregarding the seriousness of climate change and the exhaustibility of fossil fuels would have severe and unpredictable impacts, improvement of the efficiency of urban energy consumption is of utmost importance. Hence, a rather diverse spectrum of policies to encourage this improvement has been put into...

Some systems like RF energy harvesters have power transfer efficiency as one of the most important specifications. Therefore, the efficiency of the matching network, which affects the entire system’s efficiency, plays an important role. When the impedance transformation factor between the antenna and its load is high, the matching network...

The housing stock has a major energy saving potential and is mostly considered to be the sector in which energy efficiency most cost effectively could be achieved. 30% of all energy use is consumed in the housing stock. The European union has formulated targets for a reduction of CO2 emissions to be achieved by a combination of energy efficiency...

For enhancing the performance of automated container terminals, this PhD thesis focuses on improving energy efficiency and implementing more autonomous equipment (e.g., free-ranging AGVs) at the operational level. On the one hand, due to the increased energy price and environmental stress, energy efficiency needs to be improved. On the other...

This paper presents an energy-efficient readout circuit for micro-machined resonant sensors. It operates by briefly exciting the sensor at a frequency close to its resonance frequency, after which resonance frequency and quality factor are determined from a single ring-down transient. The circuit employs an inverter-based trans-impedance...

An important topic to reduce the energy consumption in railways is the use of energy-efficient train control (EETC). Modern trains allow regen-erative braking where the released kinetic energy can be reused. This regener-ative braking has an effect on the optimal driving regimes compared to trains which can only use mechanical braking. This...

This Thesis focussed on what obstacles the refining and (petro)chemical industries are facing in reaching the Energy Efficiency Directive's target. This target means that the industry should become 20% more energy efficient than projected energy efficiency levels. Interviews have been conducted with members of the whole industry chain, e.g. R&D...

The European Union formulated high ambitions of energy reductions to be realised in the built environment. The existing housing stock covers a major share of energy use and is seen as high potential to contribute to the savings. This should be realised in the first place by reducing the energy demand for heating by renovation of the existing...
