1. Low-temperature based thermal micro-grids: operation and performance assessments
Abstract : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. READ MORE

4. Exploiting the Synergies from Coupled Electricity and Heat Distribution Networks : Modelling, simulation and optimization based on an extended energy hub approach
Abstract : Recent literature shows that there is a significant potential of decarbonisation and efficiency improvement that can be achieved through the synergy from multi-energy systems (MESs). Coupling technologies, such as co-generation plants, heat pumps and thermal storages are widely recommended as means of unlocking additional flexibility and increasing the penetration of renewables in the heating and electricity sectors.

5. Vertical Display Cabinets in Supermarkets - Energy Efficiency and the Influence of Air Flows
Abstract : This thesis concerns investigations of the performance of vertical refrigerated display cabinets. Such cabinets are in widespread use and account for a considerable proportion of the energy used in shops. The open front is important for the shop-owner, who wants the chilled items in the cabinet to be well exposed and easily accessible. READ MORE
