Energy geostructures represent a renewable and clean source of energy which can be used for heating and cooling of buildings and de-icing of infrastructures. This technology couples the structural role of geostructures with the energy supply, using the pri ...
Since the beginning of the twenty-first century the limitations of the fossil age with regard to the continuing growth of energy demand, the peaking mining rate of oil, the growing impact of CO2 emissions on the environment and the dependency of the econom ...
When speaking of energy production and consumption in the context of climate change, the interest usually lies in mitigation policies and measures, i.e. the energy system is seen as an emitter of greenhouse gases. This paper takes a different approach and ...
District energy systems can potentially decrease the CO2 emissions linked to energy services, thanks to the implementation of large polygeneration energy conversion technologies connected to buildings over a network. To transfer the energy from these large ...
Energy storage systems are becoming more important for load leveling, especially for widespread use of intermittent renewable energy. Compressed air energy storage (CAES) is a promising method for energy storage, but large scale CAES is dependent on suitab ...
Due to the increase in energy prices and spiralling consumption, there is a need to greatly reduce the cost of electricity within data centers, where it makes up 50% of the total cost of the IT infrastructure. A technological solution to this is using on-c ...
Neighbourhood energy concepts for mixed industrial and commercial sites can be developed by applying energy integration techniques. This study presents an application of these techniques on a concrete site (RTA facility in Vienna, Austria), focussing on th ...
A new type of district energy network capable of providing simultaneously heating and cooling is being investigated. It is based on the use of CO2 as a heat transfer fluid by taking advantage of the latent heat of vaporization, to store and transfer heat a ...
The sun is the biggest known source of energy in our solar system. We feel its strength when it gets hot during the the day and we notice its absence during the night when we feel cold. So as to be less dependent on the sun as an energy source, we implemen ...
Liquid cooling has emerged as a promising solution for addressing the elevated temperatures in 3D stacked architectures. In this work, we first propose a framework for detailed thermal modeling of the microchannels embedded between the tiers of the 3D syst ...
