Our MSc Building Diagnostics for Energy and Environmental Performance aims to give students a solid foundation in the evaluation of the operational performance of buildings for energy and environmental aspects. The programme will focus on the diagnostics of energy and environmental performance, integrating technical and occupants’ data. It will prepare you for a future career across a range of roles in facilities and building management, consultancy, energy and environmental performance assessment and research. Most existing programmes in this subject area focus on the design of new buildings. However, the efficient operation of existing buildings is becoming more important. There is a need to improve the quality of environments and, at the same time, to reduce the energy that they consume and their carbon dioxide emissions. You will learn from interdisciplinary approaches, as the programme draws on bodies of theories from building science, social sciences and humanities. On successful completion of the programme, you should be able to conduct sound evidence-based environmental and energy performance assessments of buildings in operation. You should also be able to analyse and integrate technical and social aspects of performance using methods of energy and environmental monitoring and human studies. Our structured curriculum will enable you to develop essential knowledge and practical skills in building diagnostics. We will support you to become an independent learner, able to undertake and understand the industry and policy challenges and to respond to them effectively. The Welsh School of Architecture at Cardiff University is a friendly, supportive and culturally diverse environment in which to study.
