Holly Castleton

Dr Holly Castleton

Lecturer in Mechanical Engineering


Holly's research has predominantly focused on building energy and renewable technology performance evaluation and how evidence found from case study buildings can inform future design process/design energy predictions. Her background is in building services design and lighting research.


Prior to joining Sheffield Hallam University, Holly was a post-doctoral researcher in the lighting research group and teaching fellow in environmental design at the Sheffield School of Architecture (SSoA, The University of Sheffield).

Holly obtained her PhD and MEng degree in Mechanical Engineering from The University of Sheffield (UK). Her PhD was conducted as part of the EPSRC Energy-Futures Doctoral Training Centre, which included an additional year of research/study in a variety of Energy related topics. Her PhD research was undertaken in collaboration with international building and infrastructure consultancy Mott MacDonald, and the Technology Strategy Board (Innovate UK) Building Performance Evaluation Programme.

Holly's research contributed to the Best Building Operation award at the CIBSE Building Performance Awards (2013), as well as the Enterprise Award, and highly commended for the Field & Laboratory Research Award at the Leeds Sustainability Institute RISE (Research, Innovation, Sustainability, Enterprise) Awards 2015.

Holly also worked as a building services design engineer for international building consultancy Buro Happold prior to completing her PhD.
