Research interests

Dr Macmillan’s research interests lie in three main areas. First, the tangible and intangible benefits of a well-designed built environment, including its effect on social, economic and environmental outcomes and the different sorts of value that it delivers – whether use value and social value, or cultural value and image value. The second area is concerned with technological innovations particularly to support low energy buildings, such as smart controls, ergonomic interfaces, renewable energy sources, intelligent facades, and combined heat and power systems. The third area is in improvements in the project process, such as interdisciplinary collaboration and effective teamwork, the application of techniques like whole life costing, through to the development and implementation of tools such as Building Information Modelling (BIM).

Strategic themes

Energy, transport and urban infrastructure

Energy efficiency and integration of renewable energy technologies in buildings, energy and environment management techniques, passive design strategies to minimise energy demand in buildings, minimisation of embodied carbon in buildings.

Uncertainty, risk and resilience

Collaboration with Arup engineers on a new framework for assessing urban resilience in tomorrow’s cities.

Dr Macmillan has published extensively in the areas of environmental management of buildings, low and zero carbon building design, interdisciplinary design and integration, leadership and effective teamwork, and the added value of good design. In addition to papers in academic journals and four books, he has written a number of publications to support UK government initiatives in architecture and the built environment and in construction industry reform. Originally trained as an architect, he has worked in architectural practice and as an independent consultant, researcher and writer. He is a member of the Peer Review College of the Engineering and Physical Sciences Research Council, and a regular reviewer for the Technology Strategy Board. He is a regular referee for the journals Building Research & Information, and Design Studies.
