1. Introduction 1.1 Climate change refers to changes in long term trends of normal weather patterns. The time scale for this is observed over periods of 30 years, scientifically and spatially from a specific location. 1.2 The impacts of climate change can include extreme weather, flooding and altered habitats. However the effects of climate change can both be mitigated against and adapted to. 1.3 The purpose of this paper is to set out the planning context for climate change and examine what the potential scope of policies should be incorporated in the LAPP DPD. 1.4 The type and extent of policies that could be included within the LAPP DPD, which are being examined in this paper are: • Energy Efficiency: Solid Wall Insulation • Utilising Energy Efficient Supplies: District Heating • Maximising Use of Renewable Energy Generation Systems: Wind Turbines • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Combined Heat and Power • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Solar Thermal • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Biomass • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Heat Pumps • Carbon Offsetting • Green Infrastructure • Sustainable drainage • Flood Risk 1.5 In 2006, Nottingham generated 14.43% of its own heat and power from low or zero carbon generation. The City’s ability to adapt to climate change has also been increased recently, through the development of the Nottingham Left Bank Flood Alleviation Scheme (FAS). 2
2. National Context Climate Change Act (2008) 2.1 The Climate Change Act (2008) puts in place a legally binding target to reduce green house gas emissions by at least 80% by 2050. 2.2 The main provisions of the Act are: • Carbon targets and carbon budgeting: in addition to the long term target of at least 80% reduction in Greenhouse Gas Emissions by 2050, there is also a carbon budgeting system, which caps emissions over five year periods. • The Committee on Climate Change: The Act created an independent body to advise Government of the level of carbon budgets and where cost effective carbon savings can be made. • Trading schemes: It introduced emissions trading schemes to reduce green house gas emissions. • Impact and adaptation to climate change: The Government must report at least every five years on the risks to the UK from climate change, and publish a programme setting out how these impacts will be addressed. Powers for Government to require public bodies to carry out their own climate impact risk assessment and make plans to address those risks were also introduced. Planning and Energy Act (2008) 2.3 This Act enables Local Planning Authorities to set reasonable requirements for: • A proportion of energy used in development to be from renewable sources in the locality of the development; • A proportion of energy used in development to be low carbon energy from sources in the locality of the development; and • Development to comply with energy efficiency standards that exceed the energy requirements of building regulations. National Planning Policy Framework (2012) 2.4 The National Planning Policy Framework (NPPF), which was published in March 2012, sets out a number of requirements for planning and climate change. It requires Local Planning Authorities (LPAs) to adopt proactive strategies to mitigate and adapt to climate change, taking full 3
account of flood risk, coastal change and water supply and demand considerations. 2.5 Paragraph 95 sets out that, to support the move to a low carbon future LPAs should: • Plan for new development in locations and ways which reduce greenhouse gas emissions; • Actively support energy efficiency improvements to existing buildings; and • When setting any local requirement for a building’s sustainability, do so in a way consistent with the Government’s zero carbon buildings policy and adopt nationally described standards. 2.6 In order to increase the use and supply of renewable and low carbon energy, LPAs should recognise the responsibility on all communities to contribute to energy generation from these sources. In accordance with Paragraph 97 they should: • Have a positive strategy to promote energy from renewable and low carbon sources; • Design their policies to maximise renewable and low carbon energy development while ensuring that adverse impacts are addressed satisfactorily, including cumulative landscape and visual impacts; • Consider identifying suitable areas for renewable and low carbon energy sources, and supporting infrastructure, where this would help secure the development of such sources; • Support community-led initiatives for renewable and low carbon energy, including developments outside such areas being taken forward through neighbourhood planning; and • Identify opportunities where development can draw its energy supply from decentralised, renewable or low carbon energy supply systems and for co-locating potential heat customers and suppliers. 2.7 The NPPF also sets out specific guidance with regards planning for flooding. Paragraph 100 states that inappropriate development in areas at risk of flooding should be avoided by directing development away from areas at highest risk. Local Plans should apply a sequential, risk based approach to flooding, taking account the impacts of climate change by: 4
• Applying the Sequential Test; • If necessary, applying the Exception Test; • Safeguarding land from development that is required for current and future flood management; • Using opportunities offered by new development to reduce the causes and impacts of flooding; and • Where climate change is expected to increase flood risk so that some existing development may not be sustainable in the long- term, seeking opportunities to facilitate the relocation of development, including housing, to more sustainable locations. 2.8 Further to this, Paragraph 102 states that, if, following application of the Sequential Test, it is not possible, consistent with wider sustainability objectives, for the development to be located in zones with a lower probability of flooding, the Exception Test can be applied if appropriate. For the Exception Test to be passed: • it must be demonstrated that the development provides wider sustainability benefits to the community that outweigh flood risk, informed by a Strategic Flood Risk Assessment where one has been prepared; and • a site-specific flood risk assessment must demonstrate that the development will be safe for its lifetime taking account of the vulnerability of its users, without increasing flood risk elsewhere, and, where possible, will reduce flood risk overall. 2.9 Both elements of the test will have to be passed for development to be allocated or permitted. National Renewable Energy Action Plan (2009) 2.10 The United Kingdom is legally committed to achieving 15% of the UK’s energy demand from renewable sources by 2020. 2.11 The action plan intends to achieve the 15% target through domestic action. 2.12 It states that the UK could deliver about 30% of electricity, 12% of heat, and 10% of transport energy from renewable sources by 2020 3. City Council Guidance and Policy 3.1 The City Council has produced a number of documents that are relevant to the consideration of climate change issues and future 5
policies for inclusion in the Local Plan. The main documents for consideration are: • Sustainable Community Strategy • The Nottingham Growth Plan • Low Carbon Pioneer City • Energy Strategy • The Municipal Waste Management Strategy • Community Climate Change Strategy • The Aligned Core Strategy – Proposed Submission • The City Council Renewable Energy Requirement • Guidance on the production of Energy Statements The Sustainable Community Strategy (2009) 3.2 The Nottingham Plan to 2020 is the Sustainable Community Strategy. It has three cross-cutting aims – green (which includes climate change), aspiring, fair – and six strategic priorities: 1. Develop Nottingham’s international standing for science and innovation, sports and culture; 2. Transform Nottingham’s neighbourhoods; 3. Ensure that all children and young people thrive and achieve; 4. Tackle poverty and deprivation by getting more local people into good jobs; 5. Reduce crime, the fear of crime, substance misuse and anti- social behaviour; and 6. Improve health and wellbeing. 3.3 Under strategic priority 1, one of the headline targets is to reduce the City’s carbon emissions by 26% of 2005 levels by 2020. The 2005 baseline was 6.5 tonnes of CO2 per capita. The Nottingham Growth Plan (2012) 3.4 The Nottingham Growth Plan was launched in 2012. It sets out the strategy for economic growth within the City. One of the key sectors 6
identified for delivery in the futures ‘clean technology’, which includes companies providing technologies, goods and services that will enable the UK’s transition to a low-carbon economy. Low Carbon Pioneer City 3.5 Nottingham has been recognised by the Department of Energy and Climate Change as a Low Carbon Pioneer City. This is in recognition of Nottingham ambitious plans and investment in green infrastructure and technologies, generation of low carbon jobs, and accelerate reductions in emissions as well as its due to its role as one of the UK’s leading cities in low / zero carbon generation. Being recognised as a Low Carbon Pioneer City means that Nottingham will have access to Government Funding streams to trial initiatives before they become national schemes. 11.1 Nottingham so far has been successful in securing finding via Low Carbon Pioneer Cities programme for Heat Strategy Master Planning, which assesses the feasibility of district heating networks in the Southern Gateway, Boots Enterprise Zone, and the Creative Quarter. This funding is also looking at feasibility to develop pricing mechanisms that offer incentives to develop and connect to heat networks. 3.6 Nottingham has also secured funding for Green Deal go early, which has seen Nottingham deliver solid wall insulation, and Green Deal type assessment and measures in social housing in Nottingham, as well as workshops for the non-domestic sector to outline opportunities available through Green Deal. To continue to secure funding, our policies and strategies must Energy Strategy (2010) 3.7 Lower carbon emissions should be achieved in line with energy strategy targets 3.8 The Energy Strategy (2010-2021) provides an overarching framework for the City’s plans, programmes and initiatives relating to sustainable energy supply and use to 2021: cutting emissions, maintaining energy security, maximising economic opportunities and protecting the most vulnerable citizens. 3.9 The Action Plan prioritises the delivery of: • A 26% reduction of carbon dioxide emissions against 2005 levels, • 20% of the City’s own energy generated from low or zero carbon sources by 2020. 7
3.10 To meet the national and local targets for heat and power, the strategy sets out that the following will be required: • More than doubling the size of the City district heating network; • Development of a local biomass processing and transfer site; • Significant capacity of new biomass CHP plant with associated district heating; • Consideration of a City anaerobic digester; • Increase in low or zero carbon energy measures installed in the domestic and commercial sector. 3.11 The strategy sets out the following energy vision for Nottingham: • A city insulated against high energy prices; • Secure, low carbon energy supply and services available for businesses, public and domestic sector; • A City prepared for climate change and peak oil; • A City leading on growth in low carbon jobs, industries, services and training; • A City exemplar of integrated low carbon heat, power and transport; • An exemplar of neighbourhood community energy solutions; and • A smart City where energy flows are planned, mapped and monitored. 3.12 A detailed action plan sets out a significant number of actions through which to meet the targets and aims. One of these actions is the establishment of an Energy Park to support new and relocating energy related businesses to base their operations here. 3.13 This strategy is currently under review, and a updated version will be issued later in 2013 8
The Municipal Waste Management Strategy (2010) 3.14 ‘A Waste-Less Nottingham – Waste Strategy 2010-2030’ sets out the principles for the management of all Nottingham City’s municipal waste. 3.15 The strategy aims to deliver the following five key actions: • To produce the lowest amount of household waste per person of any Core City in England; • To increase the amount of reuse and recycling from just over a third of our waste at present to the majority of household waste (55+%); • To transform the management of trade waste and other (non household) wastes by providing new services and infrastructure to reduce, recycle and recover energy; • To save an additional 3-6000 tonnes of carbon dioxide per year by recovering energy from waste, helping to combat climate change and making the carbon savings by the waste management service around 16-19000 tonnes of CO2/year, this is 25-30% of the City Council emissions, e.g. from heating buildings, vehicle usage, street lighting etc; • To recover around 47 million kilowatt hours of energy from waste using the Energy from Waste plant at Eastcroft with associated District Heating and electricity generation scheme, and by also processing food and other organic waste in a technology known as Anaerobic Digestion. Nottingham Community Climate Change Strategy (2012) 3.16 The Nottingham Community Climate Change Strategy (2012-2020) has the following vision: • A City where there is access to secure, affordable local energy, where buildings make the most of the natural environment and are adaptable to our future climate; • A City with little congestion and vehicle use, and excellent public transport, and where vehicles are fuelled by renewable energy; • A City where you can buy local affordable food, where you have a place to breathe and enjoy the best of what nature provides; and • A City where you have a secure career at the forefront of the low carbon technology, within a thriving green economy. 9
3.17 The document recognises the links with other City Council strategies, including planning policy and the Core Strategy / Local Plan. 3.18 It also recognises Nottingham City’s plans for investing in the low carbon economy and, in particular, the existing Science City designation and the promotion of an Energy Park in Bulwell. 3.19 The document seeks to achieve behavioural change in the community and has set up a methodology through which to engage communities identify their priorities and develop an action plan. The City Council Renewable Energy Requirement (2007) 3.20 In May 2007, Nottingham City Council Executive Board approved an interim standard requiring 10% of energy supplied in all developments over 1,000 square metres to be gained from on-site or decentralised renewable or low carbon energy source. This interim measure, which is also known as a ‘Merton Rule’ was put in place to bridge the gap until the adoption of the Core Strategy. Energy Statements 3.21 In conjunction with the City Council Renewable Energy Requirement, Nottingham City Council produced guidance on how to complete an energy statement. 3.22 The key information required in these statements is: • How much CO2 will the development emit annually in operation? • Reference to how these emissions have been calculated? • Which technology has (or technologies have) been chosen to deliver a 10% reduction in annual carbon emissions? • How have annual savings from the chosen technology (or technologies) been calculated for this site? The Nottingham City Aligned Core Strategy (2012) 3.23 The Nottingham City Aligned Core Strategy was published for a six week period of formal representations from June 2012. Policy 1: Climate Change sets out the following requirements: 1. All development proposals will be expected to deliver high levels of sustainability in order to mitigate against and adapt to climate change, and to contribute to national and local targets on reducing carbon emissions and energy use. The onus will be on developers to robustly justify why full compliance with policy requirements is not viable or feasible. Sustainable Design and Adaptation 10
2. Development, including refurbishment where it requires planning permission, will be expected to demonstrate the following: a) how it makes effective use of sustainably sourced resources and materials, minimises waste, and water use. For residential development, planned water use should be no more than 105 litres per person per day; b) how it is located, laid out, sited and designed to withstand the long and short term impacts of climate change, particularly the effect of rising temperatures, sustained periods of high temperatures and periods of intense rain and storms; c) that the building form and its construction allows for adaptation to future changes in climate; and d) that the building form and its construction permits further reduction in the building’s carbon footprint, where feasible and viable. Reducing Carbon Dioxide Emissions 3. Development must demonstrate how carbon dioxide emissions have been minimised in accordance with the following energy hierarchy: a) Using less energy through energy efficient building design and construction, including thermal insulation, passive ventilation and cooling. b) Ensuring all energy consuming equipment is as efficient as possible, and well managed b) Utilising energy efficient supplies – including connecting to available and planned heat and power networks c) Maximising use of renewable and low carbon energy generation systems 4. Further guidance on how development should contribute to reducing Carbon Dioxide emissions will be set out in Development Plan Documents, where appropriate. Decentralised Energy Generation 5. The extension of existing or development of new decentralised renewable and low-carbon energy schemes appropriate for the 11
plan area will be promoted and encouraged, including biomass power generation, combined heat and power, and micro generation systems. In line with the energy hierarchy, adjacent new developments will be expected to utilise such energy wherever it is feasible and viable to do so. Flood Risk and Sustainable Drainage 6. Development proposals that avoid areas of current and future flood risk and which do not increase the risk of flooding elsewhere and where possible reduce flood risk, adopting the precautionary principle, will be supported. 7. Where no reasonable site within Flood Zone 1 is available, allocations in Flood Zone 2 and Flood Zone 3 will be considered on a sequential basis. 8. Where it is necessary to apply the Exception Test within the urban areas, the following factors will taken into account when considering if development has wider sustainability benefits to the community that outweigh flood risk:- a) there are exceptional and sustainable circumstances for locating the development within such areas, including the necessary re- use of brownfield sites; and b) the risk can be fully mitigated by engineering and design measures. 9. Where appropriate, further guidance on the application of the sequential and exception test will be set out in Local Development Documents. 10. All new development should incorporate measures to reduce surface water run-off, and the implementation of Sustainable Urban Drainage Systems into all new development will be sought unless it can be demonstrated that such measures are not viable or technically feasible. 3.24 The document, along with the representations received, will be submitted to the Secretary of State for consideration and, following this, will be adopted, if found sound. 4. Other Relevant Publications and Tools 4.1 In addition to the formal Council publications set out above, a number of other evidence base documents / tools have been developed, including: • Towards a Sustainable Energy Policy for Nottinghamshire 12
• Aecom – Greater Nottingham Draft Climate Change Policy and Evidence Base Review • Nottingham City Local Carbon Framework – Energy Calculator and Decision Support System • Allowable Solutions for Tomorrow’s New Homes: Towards a Workable Framework’ • Zero Carbon Strategies for tomorrow’s new homes Towards a Sustainable Energy Policy for Nottinghamshire (2009) 4.2 The document was prepared by Nottinghamshire Sustainable Energy Planning Partnership (NSEPP). As it was prepared in 2009, it was based upon Planning Policy Statement 1: Planning for Sustainable Development, and the companion guide, and Planning Policy Statement 22: Renewable Energy. It also used the 2006 Building Regulations as a baseline and included unregulated emissions in the definition of Zero Carbon. 4.3 The key recommendation of this document was increased carbon reduction targets above those required by building regulations, for both domestic and non-domestic development, until 2016, when the zero carbon requirement would come into force. Greater Nottingham Draft Climate Change Policy and Evidence Base Review (2012) 4.4 This document was produced by Aecom to assess the appropriateness of the Aligned Core Strategy Climate Change policy and the Towards a Sustainable Energy Policy for Nottinghamshire paper. 4.5 The document contained recommendations for changes to the Core Strategy Climate Change Policy, many of which were included in the publication version. The document suggested that the Towards a Sustainable Energy Policy for Nottinghamshire papers robustness could be brought into question on the basis that it included unregulated emissions and was based upon 2006 building regulations requirements. Nottingham City Local Carbon Framework – Energy Calculator and Decision Support System 4.6 In 2010, Nottingham City Council was awarded funding from the Department of Energy and Climate Change (DECC) as part of the Local Carbon Framework (LCF). There were two outputs from the project – an ‘Energy City Tool’ and a ‘Decision Support Tool’. Both 13
tools were developed by ESRI UK in conjunction with Nottingham City Council. 4.7 The Energy City Tool, otherwise known as the Energy Calculator enables citizens and other property owners such as commercial businesses, to better understand potential opportunities and benefits for renewable and low carbon energy investments in their properties. This includes an overview of likely up-front costs and estimated payback of taking up low carbon energy measures. The aim of the Decision Support Tool, also called the Decision Support System (DSS), is to help planners, and potentially other business users to locate opportunities for implementing renewable and low carbon generation technologies and assess their potential impact. More information on these two tools is provided in Appendix 1. Allowable Solutions for Tomorrow’s New Homes (2011) 4.8 In July 2011, the Zero Carbon Hub published ‘Allowable Solutions for Tomorrow’s New Homes: Towards a Workable Framework’. To comply with the 2016 Building Regulations, new zero carbon homes will have to meet on-site requirements for Carbon Compliance (achieved through energy efficiency of the fabric, the performance of heating, cooling and lighting systems, and low and zero carbon technologies). In addition, through Allowable Solutions (AS), they will need to account for the carbon emissions that are not expected to be achieved on site through Carbon Compliance. Carbon Compliance and Allowable Solutions measures will both be needed to meet the zero carbon Building Regulations in 2016, and each will need to be submitted, checked and verified as part of Building Control approval1. 4.9 The key parts of the consolidated framework proposal presented in the report were: • A choice for Local Planning Authorities to develop a policy on Allowable Solutions (Route A); • The opportunity, when working to Route A (i.e. to Local Plans), for housing developers to seek out best value for Allowable Solutions via a Community Energy Fund or by Private contract with a third party provider; • The option of purchasing Allowable solutions from a Private Energy Fund (Route B) when the Local Planning Authority does not have an Allowable Solutions policy; • A Verification and Certification Scheme to show that an investment will achieve the required carbon emissions reductions. The scheme will monitor Allowable Solutions 1 Source: Allowable Solutions for Tomorrow’s New Homes: Towards a Workable Framework, Zero Carbon Hub (2011) 14
delivery and release credits, certificates and finds in a timely way to facilitate Allowable Solutions project development and Buildings Regulations approval; • A single Allowable Solutions Fund Holding to provide a secure ‘Bank’ for the Allowable Solutions investment flow. 4.10 It has been proposed that there will be three routes for Allowable Solutions, on site, near site and off site. Zero Carbon Strategies for Tomorrow’s New Homes 4.11 In February 2013, the Zero Carbon Hub published ‘Zero Carbon Strategies for tomorrow’s new homes’. It sets out three strategic design approaches for complying with the zero carbon definition: • Approach A: Balanced • Approach B: Extreme Fabric • Approach C: Extreme LC (Low Carbon) Technologies Permitted Development 4.12 Many low carbon technologies are permitted development on dwelling houses, however, there are instances where they require planning permissions, for instance, in a Conservation Area with and Article 4 Direction, or where there would be a material increase in the height or appearance of the dwelling, e.g. through retrofitting solid wall insulation or solar panels. 4.13 In instances where an installation is not permitted development, planning permission must be sought. The types of development that are classed as ‘Permitted Development’ can be found in the ‘General Permitted Development Order2’. 5. Sustainable Building Standards 5.1 The Government has announced that all new homes must be zero carbon from 2016 and are considering a similar approach for new non- domestic buildings from 2019. There are several methods through which a building’s sustainability can be increased, above and beyond the Building Regulations requirements. 5.2 The Code for Sustainable Homes (the Code) is the national standard for the sustainable design and construction of new homes. The Code aims to reduce carbon emissions and create homes that are more sustainable. It measures the sustainability of new homes against nine 2 http://www.legislation.gov.uk/uksi/2011/2056/made 15
categories of sustainable design, rating the ‘whole home’ as a complete package. It covers energy / CO2, water, materials, surface water runoff (flooding and flood prevention), waste, pollution, health and well-being, management and ecology. 5.3 The Code uses a six star rating system to communicate the overall sustainability performance of new homes against the nine categories and sets minimum standards for energy and water use at each level. 5.4 The Code is not mandatory, and there is no intention to make it mandatory. The only circumstances where it can be required are: • Where Local Authorities stipulate a requirement in their Local Plans; • Where affordable housing is funded by the Homes and Community Agency (HCA), which requires homes to be built to Code Level 3. 5.5 The Level 3 energy standard is incorporated into the 2010 Building Regulations, the Level 4 energy standard will be incorporated in 2013 and the Level 6 energy standard will be incorporated in 2016. 5.6 The latest cost review for the Code for Sustainable Homes was published in 2011. This document sets out the extra-over costs for each dwelling type and development scenario with the Part L 2006 baseline3. 5.7 The most widely accepted standard for non-domestic development is the Building Research Establishment Environmental Assessment Method (BREEAM). Like the Code, it is not a statutory requirement, however, Local Authorities may incorporate the standard into their Local Plan. 5.8 For newly constructed non-domestic buildings (which include office, industrial, retail, education, healthcare, prisons, law courts and residential institutions), BREEAM looks at the following categories: • Management • Health and Wellbeing • Energy • Transport • Water 3 http://www.communities.gov.uk/publications/planningandbuilding/codeupdatedcostreview 16
• Materials • Waste • Pollution • Innovation 5.9 BREEAM scores are defined as – outstanding, excellent, very good, good, pass and unclassified. The latest guidance on BREEAM new construction was published in 2011. 6. Climate Change Mitigation 6.1 Mitigating means to alleviate some of the force or intensity of something. In terms of climate change, any activity which reduces the effects of climate change, such as energy use reduction, can be said to ‘mitigate’ climate change. 6.2 Given the context set out in Sections 2 to 5 and the energy hierarchy contained within the Aligned Core Strategy Policy, the issues surrounding climate change mitigation considered in this Background Paper are: • Energy Efficiency: Solid Wall Insulation • Utilising Energy Efficient Supplies: District Heating • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Wind Turbines • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Combined Heat and Power • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Solar Thermal • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Biomass • Maximising Use of Renewable and Low Carbon Energy Generation Systems: Heat Pumps • Carbon Offsetting Energy Efficiency: Solid Wall Insulation 6.3 The majority of energy efficient measures that are retrofitted do not require planning permission, however, as set out above, there are 17
instances where this is not the case. Retrofitting solid wall insulation is one instance where planning permission may be necessary. 6.4 Where planning permission is required, planning policies should be in place by which to judge any planning application. Utilising Energy Efficient Supplies: District Heating 6.5 Aligned Core Strategy Policy 1 sets out that energy efficient supplies should be utilised where possible, including connection to available heat and power networks. 6.6 Nottingham City currently has an extensive district heating network, which is run by EnviroEnergy via heat received from the Eastcroft Energy from Waste facility. 6.7 The existing district heating network runs into St Ann’s and the Lace Market, and was recently extended to the south of the City Centre. 6.8 The existing network has capacity at many points, however, it is not possible to connect at all points in the network. Consultation with EnviroEnergy should establish whether it is possible to connect through development. 6.9 Aligned Core Strategy Policy 1 makes it clear that new developments are requested to connect to existing schemes where feasible and viable to do so. However, many schemes expand over time and, whilst it may not be possible to connect to a district heating scheme at present, it may be possible to connect to a scheme in the future. Therefore, new developments should be designed so they are capable of connecting to a district heating scheme in the future. Maximising Use of Renewable and Low Carbon Energy Generation Systems: Wind Turbines 6.10 Aligned Core Strategy Policy 1 sets out that the use of renewable and low carbon energy generation systems should be maximised. 6.11 The development of the Decision Support System (DSS) energy mapping exercise that was undertaken in Nottingham established parameters for which it considered wind technology suitable. However, whilst it sets out ‘suitable, possible and unsuitable’ locations for wind turbines, the following should be taken into consideration: • The tool only details the appropriateness of medium scale wind turbines • Medium scale is defined as 100 to 500kw rating • Other scales of turbine have not been assessed 18
• The tool is a guide only and should not be taken as a definitive answer as to whether wind turbines are suitable in a particular location, or whether they would be granted planning permission in a particular location. 6.12 The following table defines what is unsuitable, possible and suitable (as mapped in the tool): Classification Definition Unsuitable Any areas less than 80m away from buildings, unless only 1 building is affected. Possible Any areas between 80 -100m away from buildings, or less than 80m from a building if only 1 building is affected. Suitable Any areas greater than 100m away from buildings. 6.13 The following constraints were taken into consideration when developing the model: Dataset Constraint parameters Inland Water Exclude areas Electricity Transmission lines Exclude areas within 25m Masts Exclude areas within 25m Pylons Exclude areas within 25m Roads Exclude areas within 15m Railways Exclude areas within 15m Scheduled Ancient Monuments Exclude areas within 80m SSSI Exclude areas within 100m Local Nature reserves Exclude areas within 100m Ancient Woodland Exclude areas within 100m BioSincs Exclude areas within 100m Listed Buildings Exclude areas within 100m Conservation Areas Exclude areas within 100m GeoSincs Exclude areas within 100m Mobile Phone Operators Exclude areas within 25m Tram line Exclude areas within 15m Wind Speed (10m above land) Exclude areas with a wind speed lower than 4.5m/sec 6.14 Whilst the energy map does not consider mircogeneration, small or large scale turbines, it is still important to establish planning policies through which to consider any planning application. 6.15 Microgeneration schemes (less than 1.5kw) are permitted development in most instances. Small scale is defined as 1.5 to 100kw and large scale is defined as over 500kw. The guidelines for minimum distances are 2.5kw to 10kw turbine up to 100m, 10kw to 50kw turbine over 100m from the nearest line of sight. 19
6.16 Regardless of the minimum distances that are required to establish suitability in principle, there are other factors that are required in order to demonstrate the acceptability of a wind turbine. These include the impact on local amenity in terms of: • Noise • Shadow flicker and • Visual dominance 6.17 Other potential relevant impacts can include: • Impact on historic environment • Ground conditions • Natural environment • Air safety (electro-magnetic interference) and • Transport 6.18 It is important that any planning policy addresses the different acceptable distances for each size of wind turbine, as well as the other potential impacts. Maximising Use of Renewable and Low Carbon Energy Generation Systems: Combined Heat and Power 6.19 The Decision Support System (DSS) energy map also shows the potential heat loads within the City, i.e. areas within the City where there are facilities that have large heat requirements. This is an important aspect of the tool, as it enables the identification of areas where a Combined Heat and Power (CHP) scheme may be needed. This is not to say that a scheme would not be suitable in other locations, but that the development of such schemes should be preferred within these areas as there is an identified use for the excess heat. Planning policies should try to locate CHP facilities within those areas where there is an identified need where possible. 6.20 Combined heat and power schemes can take many forms, and include: • Biomass • Gas 6.21 Energy from Waste plants, such as the Eastcroft facility, can also contribute to CHP and district heating. Waste planning is, however, a 20
separate matter and documents are produced jointly with the County Council. Maximising Use of Renewable and Low Carbon Energy Generation Systems: Solar Thermal, Biomass and Ground / Air Source Heat Pumps 6.22 The Nottingham Energy Strategy has targets for the installation of solar thermal hot water systems, biomass systems, and heat pumps 6.23 These technologies should be a viable option where it is not possible to connect to the district heating network. 6.24 These measures should be a viable alternative to grid supplied natural gas, and evidence will be provided where these measures cannot be installed. 6.25 Further information on renewable technologies can be found at Nottingham Energy Partnership at http://www.nottenergy.com/renewables/. Carbon Offsetting 6.26 Whilst the Government has not produced final guidance relating to Allowable Solutions, the guidance produced to date indicates that such a scheme would be used to account for the carbon emissions that are not expected to be achieved on site through Carbon Compliance, i.e. Allowable Solutions will be required in addition to onsite measures to deliver zero carbon by 2016. 6.27 The proposed Core Strategy policy does not require a contribution to carbon reduction above building regulations, therefore, there will be no need to contribute to a carbon offsetting scheme prior to the anticipated introduction of zero carbon in 2016 7. Locally Derived National Standards 7.1 The Code for Sustainable Homes is the nationally recognised sustainability standard for housing, whilst BREEAM is the nationally recognised sustainability standard for other forms of development 7.2 Whilst there is no requirement to adopt a certain level of these standards, planning authorities may do so through planning policies, where justified. The AECOM review of current policy practice highlighted examples where authorities had used standards in policies. 7.3 Viability can be a significant issue when prescribing such standards. The ‘Nottingham Core Affordable Housing Viability Assessment: Final Report’ raised questions regarding the viability of affordable housing within some areas of Nottingham. 21
7.4 It is likely that including a policy requirement to provide a certain level on the Code for Sustainable Homes could have an impact on the viability of development, in some areas. However, this is not to say that a policy could not set out a requirement, subject to site by site viability and technical feasibility. 7.5 Similarly, requiring a particular level of BREEAM could have an impact on the viability of development but a policy requirement could be put in place making any such requirement subject to viability or technical feasibility. 7.6 When developing site specific allocations, consideration should be given to whether any specific requirements can be established, rather than applying the general Development Management policy to the allocation. 8. Climate Change Adaptation 8.1 Adaptation means responding to the impact of a changing climate, i.e. seeking to lower the risks posed by the consequences of climate change through incorporating measures in new development, such as sustainable drainage infrastructure and planting extra trees. 8.2 The Aligned Core Strategy Publication (June 2012) sets out that development should demonstrate: • how it is located, laid out, sited and designed to withstand the long and short term impacts of climate change, particularly the effect of rising temperatures, sustained periods of high temperatures and periods of intense rain and storms; and • that the building form and its construction allows for adaptation to future changes in climate. 8.3 Given the context set out in Sections 2 to 5 and the energy hierarchy contained within the Aligned Core Strategy Policy, the issues surrounding climate change adaptation considered in this Background Paper are: • Green Infrastructure • Sustainable drainage • Flood Risk Green Infrastructure 8.4 Green Infrastructure (GI) is the strategically planned network of multifunctional green spaces and other environmental features. It may 22
run across Local Authority boundaries and the Greater Nottingham Aligned Core Strategies sets out policies for the promotion of GI and maps the strategic network. 8.5 Mapping GI, or the potential for GI, can both help protect the existing features, as well as enabling the expansion of the network through development. Sustainable Drainage Systems (SuDS) 8.6 SuDS are defined as management practices and control systems designed to drain surface water in a more sustainable way than conventional systems. Reducing and decreasing the amount of surface water run-off helps to manage water resources more sustainably and helps meet national planning policy which promotes the control of surface water run-off as near to the source as possible. SuDS also have a role in improving the quality of the run-off from a development and enhancing nature conservation/biodiversity, particularly in densely built up urban areas. 8.7 SuDS schemes can vary in size and composition and can be used in most developments where the flow of water would be large enough to be readily reduced. Preventative measures, such as basic good housekeeping, are always the first stage of the SuDS approach to avert or reduce pollution and run-off quantities. Techniques which can be incorporated in developing SuDS vary from the relatively straightforward such as soakaways and reducing areas of impervious surfaces on a site through to green roofs and using swales, basins, infiltration trenches, filter drains and drainage ponds to collect and store water. Flood Risk 8.8 Policy 1 of the Aligned Core Strategy seeks to allocate sites away from areas of greatest flood risk, i.e. it applies a sequential approach and, where necessary, the exception test. 8.9 The National Planning Policy Framework (NPPF) provides further guidance on the allocation and granting planning permission of sites within areas of flood risk. 8.10 In accordance with the NPPF, where relevant, planning applications for new development should be informed by a site specific flood risk assessment, following the sequential test and, if required the exception test. 9. Sustainability Statements 9.1 Sustainability statements are often produced in order to assess the sustainability measures that are incorporated into development and 23
ensure that they meet policy requirements. At present, Nottingham City Council requires ‘Energy Statements’ to be produced to ensure that development provides the 10% renewable energy requirement, or equivalent from other sources. 9.2 National standards, such as the Code for Sustainable Homes and BREEAM, require that a statement should be produced in order to assess how a development meets the requirements of a given level. Therefore, if these standards are required, it will not be necessary to require a separate sustainability statement. 9.3 If, however, these standards are not required, then it may be necessary to require sustainability statements to demonstrate how the requirements of the Greater Nottingham Aligned Core Strategies and the Local Plan have been met. 10. Viability and Feasibility 10.1 Placing additional requirements on development can add to the cost of a scheme and, in some cases, may make it unviable. Similarly, it may not be technically feasible to provide some measures onsite. 10.2 In order to ensure the deliverability of Local Plans, undue burdens should not be placed on development in accordance with the NPPF. In order to ensure compliance with the NPPF, a plan-wide viability assessment will be undertaken, following consultation on the Preferred Option. 11. Conclusions 11.1 Nottingham is recognised as being a Low Carbon Pioneer City, due to its role as one of the UK’s leading cities in low / zero carbon generation. It has secured funding in the past due to this and, in the future, will be in a good position to receive further funding. The desire for Nottingham to develop low carbon employment is set out in the Growth Plan, which seeks to develop ‘clean technology’, and also the Sustainable Community Strategy (SCS), in which ‘green’ is one of the key themes. 11.2 To date, there have been a number of successful low carbon / sustainable developments and initiatives within Nottingham, including: • 16.7% reduction in City CO2 between 2005 and 2009 • Most energy self sufficient City in the UK, with 11% of heat and power generated from renewables and waste • Solar Photovoltaic Panels: over 1800 installed on social housing 24
• Founding member of the Nottingham Declaration on Climate Change 11.3 Nottingham also has a number of unique assets, including, an extensive existing district heating network. 11.4 Based upon this context, the City is therefore in a good position to provide higher levels of sustainable development in the future than other UK cities and planning policy is one of the key tools for delivering this sustainable development. 11.5 It is, therefore, recommended that, in addition to the Core Strategy policies, future planning policies should seek a higher level of sustainability in development. Measures should include: • Incorporation of the Code for Sustainable Homes into policy; • Incorporation of BREEAM into policy; • Seeking Allowable Solutions contributions in policy; • Setting out requirements for renewable energy development in policy; • Seeking connection to, and expansion of, the district heating network through policy; • Setting our policies surrounding flood risk and climate change adaptation. 25
