Digital Twins for Sustainable Indoor Built Environments: Enhancing Occupant Wellbeing and Environmental Performance

Edinburgh Napier University is offering a PhD project focused on using Digital Twin technology to enhance occupant wellbeing and environmental performance in indoor built environments. The research aims to optimize energy use while maintaining comfort, using real-time data to improve building management. Candidates should have a relevant degree and strong analytical skills, with an interest in sustainability and building performance. This position is based in the United Kingdom.
With people spending the vast majority of their lives indoors, the quality of our homes, offices, and schools has a profound impact on our health, wellbeing, and productivity. Simultaneously, the energy used to heat, cool, and light these spaces is a major contributor to global carbon emissions. This creates a critical challenge for the built environment: how to achieve substantial energy reductions without compromising the health and comfort of building occupants. Traditional, static approaches to building design and operation often fail to dynamically balance these competing priorities.

This PhD project will investigate an innovative solution to this challenge: the application of Digital Twin technology. A Digital Twin is a dynamic, virtual replica of a physical building that is continuously updated with real-time data from sensors and systems. This research posits that these evolving digital models offer a transformative way to understand and optimise indoor environments, moving beyond static design to active, responsive management.

The project aims to develop and test a framework for using Digital Twins to enhance both sustainability and occupant wellbeing. Key research questions will include: How can real-time data on air quality, temperature, and occupancy be used to optimise energy use while maintaining comfort? Can we predict and prevent conditions that lead to poor health outcomes or high energy consumption? How can occupant feedback be integrated into building operations to create more responsive and satisfying environments?

The research will explore the practicalities of implementing this technology, addressing challenges such as integrating data from diverse building systems, ensuring data privacy, and defining the new skills required for facility managers. By combining case studies of real buildings with simulation-based analysis, this project will produce a robust evidence base and a practical roadmap for industry adoption.

This project offers an exciting opportunity to work at the intersection of sustainability, digital innovation, and human-centred design. The successful candidate will contribute to a growing field that is essential for creating future-proof buildings that are not only energy-efficient but also actively promote the health and wellbeing of their occupants.
