Renewable energy sources have an intermittent character that does not necessarily match energy demand. Such imbalances tend to increase system cost as they require mitigation measures and this is undesirable when available resources should be focused on increasing renewable energy supply. Matching supply …

At the University of Applied Science Utrecht we have been working on optimising the sustainable use of space for a long time. There are various reasons for this, such as the high costs per square meter, the shortage of space at peak times and the vacancy rate at off-peak moments. There are complaints …

The Heating Ventilation and Air Conditioning (HVAC) sector is responsible for a large part of the total worldwide energy consumption, a significant part of which is caused by incorrect operation of controls and maintenance. HVAC systems are becoming increasingly complex, especially due to multi-commodity …

The sustainable energy transition asks for new and innovative solutions in the way society, government, energy market and clients (end users) approach energy distribution and consumption. The energy transition provides great opportunity to develop innovative solutions where in the dense built environment …

In daily life, the amount of carbon dioxide emitted from building heating, cooling and electricity consumption accounts for 47% of the total building carbon dioxide emissions. This makes people pay too much attention to energy conservation and emission reduction, which leads to the neglect of a pleasant …

This report describes how a PV module laminator for high-end flexible PV modules can be made from an existing machine base. In this report, the lamination cycle is explained and lamination tests are performed from which the requirements are set up. This project started with an existing machine base upon …

Machine learning models have proven to be reliable methods in classification tasks. However, little research has been conducted on the classification of dwelling characteristics based on smart meter and weather data before. Gaining insights into dwelling characteristics, which comprise of the type of …

Renewable energy systems are a crucial technological development needed to combat climate change. This thesis covers the design and implementation of a mathematical optimization model, which calculates the lowest cost of hydrogen for certain renewable energy system configurations. The output of the model …

Current methods for energy diagnosis in heating, ventilation and air conditioning (HVAC) systems are not consistent with process and instrumentation diagrams (P&IDs) as used by engineers to design and operate these systems, leading to very limited application of energy performance diagnosis in practice. …

Current symptom detection methods for energy diagnosis in heating, ventilation and air conditioning (HVAC) systems are not standardised and not consistent with HVAC process and instrumentation diagrams (P&IDs) as used by engineers to design and operate these systems, leading to a very limited application …
