Bristol Temple Quarter Sustainable Energy Masterplan
A zero-carbon urban regeneration project
Project duration: May 2013 to October 2014
Bristol City Council (BCC) commissioned the Centre for Sustainable Energy (CSE) to develop the basis for a sustainable energy masterplan for the development of the Temple Quarter Enterprise Zone (TQEZ). There is an aspiration for the project to be a Zero Carbon development; this called for a review of options for installing low and zero carbon energy supply technologies within the TQEZ at both the micro and district scale, and recommendations for their effective delivery.

TQEZ covers approximately 70 hectares of land in central Bristol, and its development forms one of the largest urban regeneration projects currently underway in the UK.
CSE was well suited to the task having developed the National Heat Map to support the planning and deployment of low-carbon energy projects in England, providing advanced understanding of district heating options. Additionally, area- and site- based assessment work has given our team extensive experience of microgeneration options, including solar, biomass and heat pumps.
The study included a review of:
- Baseline energy demands and related carbon emissions arising from existing and proposed buildings within the TQEZ.
- Available renewable energy resources and constraints.
- Low and zero carbon energy supply opportunities, including modelling of various potential scenarios.
- Planning policy considerations and delivery options.
- Stakeholder engagement activities undertaken within the study.
The modelled carbon reduction scenarios were combinations of building-integrated renewables and combined heat and power (CHP) district energy systems. Large scale biomass CHP was found to be the most promising supply option in terms of contributing to the zero carbon target. Technically and financially viable building-integrated renewables could also contribute to significant emission savings and used alongside the district CHP systems.
The key recommendations for refining the TQEZ masterplan were to prioritise stakeholder engagement to develop a model that reflects a shared vision and strategy, and provide zero carbon support to developers to make investing in the delivery of decarbonisation requirements an attractive option. In order to achieve this, CSE recommended that BCC:
- Facilitate a more detailed energy masterplanning process (with the STEEP process) to engage stakeholders
- Define and further investigate the most suitable district heating network option
- Provide Zero Carbon support to developers
- Embed Zero Carbon infrastructure across all TQEZ developments
- Maximise use of local sustainable energy resources
