The University seeks to reduce scope 1 carbon emissions from around 18,000 COt pa to 4,000 COt pa by 2035. This can only be achieved by replacing gas plant with lower carbon intensive alternatives. This will generally feature heat pumps arranged individually or as networks. This deployment requires a focus on related estates-wide issues including building performance optimisation, electricity use and supply, system resilience, and metering and control, as well as the practicalities of delivery and cost. The University does not have all the answers, but there is a clear approach and this talk introduces the activities the University is taking to address this challenge.
