Summary

The aim of LoT-NET is to prove a cost-effective near-zero emissions solution for heating and cooling that realises the huge potential of waste heat and renewable energies by utilising a combination of a low-cost low-loss flexible heat distribution network together with novel input, output and storage technologies.

The EU is cutting the availability of hydrofluorocarbons (HFCs) by 79% between 2015 and 2030 due to high Global Warming Potential and alternative fluids must be evaluated. BEIS see heat pumps as part of decarbonisation of space heating but their high cost is noted by BEIS involvement in the global initiative “Mission Innovation: Affordable Heating and Cooling”. The vapour compression heat pump operating in conjunction with lower grade heat networks e.g. below 30°C or solar energy, can uplift such heat to underfloor heating temperatures (<40°C) with a coefficient of performance >10 (very low running costs) and provide domestic hot water temperatures avoiding legionella concerns (~60°C) with a coefficient of performance >5.0 with current refrigerants e.g. R410a and R32. However revised heat exchangers must be developed. Extending the temperature lift further sees fluids such as R1233zd being able to upgrade low grade waste heat to process temperatures.

Thus, this project will focus initially on the development of low temperature lift heat pumps focussing on novel evaporator development and solar augmentation. It will then extend into higher temperature units to address space heating and process applications.

I had an interesting time at Ulster University, Jordanstown. Many thanks to all the lecturers, library staff and research school for their time and effort getting me through my PhD!

My proudest moment was when I was accepted to pursue my PhD in Ulster University. My favourite memory was how I met my group of friends who also pursue their dreams in this foreign country. I'll never forget the tough times I underwent during my study, but thanks to those times that I finally managed to lose weight. I couldn't have got through this without my supervisors' support, kind encouragement and firmest trust. If I could speak to myself at the start of my PhD, the best piece of advice I would give myself would be - do not procrastinate, you gotta learn to move forward in life when you feel stuck.

I came to Ulster University to challenge myself with a PhD study under Vice-Chancellor's Research Studentship at the Centre for Sustainable Technologies in Architecture, Built Environment and Planning. My supervisors helped me much from giving valuable guidance to supporting any difficulties, which makes me feel that I am the luckiest student.I would like to take this opportunity to thank my supervisors, family, friends and colleagues for supporting me tirelessly. Without you, I couldn't have got through my PhD with some great achievements:Best PhD Research Paper in Architecture, Built Environment and Planning, Ulster UniversityBest Student Paper Award at the conference of World Congress on Engineering and Computer Science 2017, San Francisco, USA.Student Registration Grant for demonstrating academic excellence in research at 17th International Conference on Sustainable Technologies (SET 2018), China.

My academic background includes a MSc in Process Safety Technology, in which my topic of thesis involved the use of hydrogen as an energy carrier. This prompted me to further my knowledge in this field by embarking on a PhD at the HySAFER institute at Ulster University. Here, I conducted research on the consequences of stored hydrogen tank rupture in confined space, with the use of computational fluid dynamics.My proudest moment in all of this was informing my parents, not only for being accepted as a PhD researcher at Ulster University, but also after three years that it was indeed completed. It goes without saying that without the guidance and support from my supervisors, the companionship created by my fellow colleagues with whom I shared an office with, and the people otherwise encountered and befriended during this period, the light at the end of the tunnel of it all would have rather been a train. And for that, I will be forever grateful and all the attained memories preserved

I worked for 35 years for the Housing Executive - latterly as its Head of Research. I had completed an MSc in Urban Policy in the 2000s - and it had been a longstanding ambition of mine to complete a PhD that brought together a number of strands of policy-related research that had been of particular interest to me. Undertaking a PhD at Ulster University allowed me to fulfil this ambition in an enjoyable manner.Completing my PhD has brought me an immense amount of personal satisfaction. A major part of this was down to the incredible support I received from my two supervisors Professor Stanley McGreal and Dr Michael McCord. Their ongoing advice, encouragement and support helped take me outside my comfort zone and played a major part in my achievement. Even my viva proved to be an enjoyable experience and enabled me to feel that I had gained a level of expertise in a sphere that could make a small but significant contribution to addressing some of the key housing issues facing policy

I am a senior researcher at Korea Fire Institute which is a state-owned company specialised at fire safety engineering in the Republic of Korea. I obtained BSc and MSc in mechanical engineering. Prior to enter a PhD course at the School of the Built Environment in Ulster University, I worked for over a decade in the engineering industry. With relation to my PhD topic, my current research field is on fire safety using experimental and numerical approaches.Finally, I finished my study in Ulster University and became a Doctor of Philosophy in a field of fire safety!! There were a lot of good memories at Ulster University. I will never forget the rainbow on the Jordanstown campus which helps me to relieve my stress caused by stuck in concrete damaged plasticity theory. I felt great when receiving an annual PhD conference award as the best poster. I was excited to spent time with my officemates, Rumeel, and Emmanuel. I love every moment at Room 4B01 because it was a time to enhance my

I studied my Integrated Masters (MSci) at Jordanstown from 2008-2012. After a few years working as an Estate Agent, I went back to academia to complete my PhD, looking at the broad area of health within the field of planning.Many PhDs are given a topic to begin with, however when I applied for the PhD scholarship I had to create my own research topic. This took me a while to establish, but eventually my hard work paid off and I narrowed my research into an area I am truly proud of - Active living, how the built environment can influence physical activity and how this was interpreted in the domains listed in my thesis title. My favourite aspect of the PhD was presenting my research and getting the acknowledgment from other academics that my research was interesting, robust and well thought out. I submitted an abstract to AESOP, an annual planning conference, and was given the opportunity to present my work in Venice. I also presented my work to the president of RTPI. There is nothing
