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 …

Residential electricity distribution grid capacity is based on the typical peak load of a house and the load simultaneity factor. Historically, these values have remained predictable, but this is expected to change due to increasing electric heating using heat pumps and rooftop solar panel electricity …

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 …

There is an urgent need for energy renovation of the existing building stock to reach the climate goals, set in Paris in 2016. Unfortunately, energy renovation rates across the EU remain at a low level of 1% per year. Moreover, the depth of the achieved energy renovation is in most cases rather shallow. …

Droop control is used for power management in DC grids. Based on the level of the DC grid voltage, the amount of power regulated to or from the appliance is regulated such, that power management is possible. The Universal 4 Leg is a laboratory setup for studying the functionality of a grid manager for …

Het doel van dit rapport is meer zicht te krijgen op de vraag in welke mate en hoe burgerinitiatieven rond collectieve warmtenetten erin slaagden resultaat te boeken. Sinds enige jaren ontstaan steeds meer van dit soort initiatieven in Nederland, in navolging van wind- en zonne-energiecoöperaties, en …

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. …
