AI software to help construction industry reduce embodied carbon

Computer scientists at the University of the West of England (UWE Bristol) are developing software that uses artificial intelligence (AI) to help construction companies reduce the amount of embodied carbon in their projects.

UWE Bristol’s Big Data Laboratory is leading the two-year project, which began in November, in collaboration with Winvic Construction and Costain, as well as working with Edgetrix, a start-up that specialises in cloud and AI solutions.

Together they are developing a programme that radically speeds up the process of determining how to reduce embodied carbon at the planning stages.

Embodied carbon is the amount of energy (measured in CO2) consumed during the project’s construction phase and includes emissions from material extraction or manufacturing, transport of materials, among others.

The £800,000 project is funded by Innovate UK, the UK’s innovation agency that works with organisations to drive the science and technology innovations that will grow the UK economy.

Dr Lukman Akanbi, who is leading the project and works at UWE Bristol, said: “We are going to collect embodied carbon data from previous projects and machine learning models will be developed to learn the patterns from this data. The system will then be able to come up with alternative materials quicker.

“For a large scale project for example, instead of taking 5-10 hours to work out alternatives, it could initially take only one to two hours and further down the road, once more data is gathered, just a few minutes.”

The work, which started in November, will initially use Winvic and Costain’s commercial premises as test sites for the AI solution. The plan is then to roll out the software to building designers and others working in the construction industry.

Dr Akanbi, added: “The objective is to make the system available to building designers and enable them to use it as part of their existing design systems, such as Autodesk Revit. This way they can implement embodied carbon analysis incrementally throughout construction projects’ delivery.

“UWE Bristol is a university that’s environmentally aware and is aiming to be carbon neutral by 2030, so it’s great that we are taking a lead in a project that is looking to help achieve similar aims.”
