Presentation on The Impact of Listed Building Legislation on Energy Efficiency given by Jennifer Gregory, University of Edinburgh (and based upon her MSc thesis) at the JISC GECO/STEEV Green Energy Tech Event (#e3vis) on Thursday 13th October 2011.

1. The Impact of Listed Building Legislation on Energy Efficiency Presentation of Dissertation Findings 13/10/2011 Jennifer Gregory 1

2. Structure of Presentation Energy efficiency in existing buildings Method Results: Energy Efficiency of Public Buildings Energy Efficiency of Listed Buildings and Conservation Areas Case Studies University of Edinburgh 2

3. Energy Efficiency in Existing Buildings Buildings account for around 45% of the UK’s carbon emissions. 80% of the buildings used in 2050 will have already been built today. Potential energy savings in commercial buildings are 50-75%, potentially even higher in listed buildings. 3

4. Method Analyse a database of DEC certificate data for the City of London 2. Time series analysis 3. Case Studies Performance Indicators: EPOR/ Asset Ratio CO2 emissions/m2 4

5. Energy Efficiency of Public Buildings in England and Wales Average EPOR in 2008/09: 112 Percentage of buildings in each EPOR band: Emission reduction potential of public buildings is over 2.7Mt EPOR’s reduced on average by 7.6% over the last 3 years 5

6. Energy Efficiency Performance in Listed Buildings and Conservation Areas Percentage of Buildings in each EPOR band: 6

7. Time series analysis: On average the EPOR’s of the City of London sample increased by 9.8% from 2008/09 to 2010/11. EPOR’s of L&C buildings increased by 60% EPOR’s of non-L&C buildings increased by 2% Energy Efficiency Performance in Listed Buildings and Conservation Areas 7

10. Discussion DEC Database Potential for further research Non-availability of the informationand use EPC’s in Scotland Use Non-availability of the information The way forward: More discussion, earlier Better guidance 10

11. Conclusions Planning Legislation acts as a barrier to climate change mitigation in buildings by: Preventing the installation of energy efficiency measures Adding to the resources needed in the planning process A balance between the conservation of the building and the conservation of the environment needs to be found 11
