2. Sustainable Heritage and PPS5Is Sustainable Heritage an Oxymoron?Andrew Tegg – DPP HeritageMary Rawlinson – DPP Sustainability Emerging Contexts for Heritage Conservation 23rd February 2011 Leeds

3. Introduction to DPP LLP • Established in 1973 • 10 offices across the UK and Ireland • 160 Partners and Staff • ISO 9001 registered • Full range of planning services • Planning • Heritage • Sustainability • Urban Design

4. Introduction • Why does heritage planning need to be sustainable? • Requirements of PPS5 • Available guidance • The sustainability viewpoint • Case Studies

5. Why does heritage planning need to be sustainable:

6. Why does heritage planning need to be sustainable: Existing homes will make up 2/3 of the housing stock in 2050, ¼ of the existing stock are what can be considered traditional. 46% of CO2 emissions come from dwellings….

7. Strong foundations…. • Historic settlement layouts reflect sustainable principles in spatial planning (residential, commercial and leisure resources in settlement centres) • Historically heating your property was expensive so thick walls and small openings • Buildings were constructed using local materials • Therefore good foundations for sustainable living within historic assets

8. Two distinct areas of consideration: • Large scale infrastructure projects • Small scale site specific projects

9. Requirements of PPS5: Para 6… Planning has a central role to play in conserving our heritage assets and utilising the historic environment in creating sustainable places… Key policy….. HE1 – Heritage Assets and Climate Change • HE1.1 - Importance of seeking opportunities to mitigate and adapt to the effects of climate change when devising policies and making decisions relating to heritage assets so as to reduce carbon emissions and securing sustainable development. • Opportunities include energy efficiency, improving resilience, better use of renewable energy, sustainable use of water

10. Requirements of PPS5: Key policy….. HE1 – Heritage Assets and Climate Change • HE1.2 – Where proposals that are promoted for the ability to mitigate climate change have a potentially negative impact, LPA should prior to determination and ideally during pre-application help applicant to identify feasible solutions to deliver benefits with less harm to heritage assets. • HE1.3 – Where conflict is unavoidable public benefits should be weighed against potential harm to heritage assets in accordance with other policies in PPS5 and other documents.

11. Assessment process: Potential for pre-app as per HE1 Proposal HER searches/site assessment - identify physical impacts/setting Identify Assets Assess significance of assets and wider settings Assessment of Significance Assessment of Impacts HE7, HE8, HE9, HE10 Does the proposal cause harm – is it substantial? Consideration against PPS5 Policies Consideration against local policies Local policy, SPD etc Do benefits outweigh harm? HE9.2 or HE9.4 Decision

12. Other guidance available Various documents been prepared by English Heritage to provide guidance and advice to applicants and decision makers….

13. Other guidance available

14. Opportunities Historic Environment Planning Practice Guide suggests opportunities to achieve objectives • Production of SPD – using skills and knowledge of heritage and sustainability experts to set out ways in which heritage assets can be modified to improve their environment performance without damaging significance. • Prepare plan policies for particular assets or asset types to manage conflicts. Promote improved standards through design and awards. • Take account of positive role historic environment can make to achieving climate change aims. • Consider best practice through LDF annual monitoring reviews.

15. Opportunities Large scale energy generation and other infrastructure (Para 26 – Planning Practice Guide) • Balancing benefits in renewable energy with potential to impact on large number of differing types of heritage asset. • Importance of early discussion and co-operation between developer and local authority – try to establish acceptable balance. • Scope for LPA’s to prepare specific policies for handling such applications.

16. The sustainability viewpoint Triple bottom line

17. The Oxymoron Draughty old buildings, with untouchable façades… Chandlerkbs.com Sleek and Modern Green Bling RE World.com

18. Blame Cycle Occupiers “We would like to have environmentally efficient buildings to fulfil our policy commitments, but there aren’t any.” Constructors “We can build environmentally efficient buildings but the developers don’t ask for them.” Investors “We would fund environmentally efficient buildings but there is no demand for them.” Developers “We would ask for environmentally efficient buildings but the investors won’t pay for them.” Sir Martin Laing’s Sustainable Construction Task Group

19. National Trust Six L’s Longevity Loose-fit Lovability Low Carbon Liked by Occupiers Location

20. Evidence for Sustainability • RICS study, Doing well by doing good? identified: • energy-efficient buildings attract rental premiums of more than 6%; • "green" buildings worth 16% more than standard stock; • a high Energy Star rating attracted 3% per sq ft more rent compared with non-green buildings of the same size, location and function; • Including rent-free periods and other concessions, the premium rose to 6%; • sale price of "green" buildings was more than 16% higher; • upgrading the average non green building would increase its capital value by £3.85m • Tenants and investors would pay more for an energy-efficient building, but not for buildings that were sustainable in a broader sense. • Non-green buildings will eventually become an outdated model.

21. Return on Investment • 95% of unlisted UK and continental European real estate fund managers believe there is a relationship between environmental performance and financial returns. However, the majority felt this relationship was difficult to quantify at the current time.” Aviva Investors and the Environment Agency Pension Fund survey in May 2009

22. Case studies – The Grange, Seacroft Re-occupation of a long empty site Within a district centre for access Sustainability measures included

23. Case studies – MOJ, Marylebone Technologies included Solar water heating Ground source heating Ground source cooling Rainwater harvesting Courtesy Shove media • Other measures • High performance glazing • Thermal mass • Shading • Air permeability rates

24. Case studies – Tesco Express Signage Issues Character preservation Energy efficiency Emissions Materials • Refrigeration • Water consumption • Recycling • Travel

25. Sustainability Conundrums • Market value of a conserved building • Cost of conservation • Conservation as a catalyst • Building appreciation

26. Summary Important to understand and promote the energy saving credentials of historic assets. Wherever possible early discussions should be completed between all parties. Substantial advice available. Conservation appreciation
