Tackling climate change remains a key government priority for the planning system. Woking Borough Council has taken a strong lead on tackling the causes of climate change, and has led the way in developing sustainable energy. Our Climate Change Strategy commits the Council to setting the highest standards for new development.
The Core Strategy, adopted by the Council at its meeting on 25 October 2012, is the main document within the Council's Local Development Framework (LDF) and conforms to national planning policy. The Core Strategy sets out a 'spatial vision' of how the Borough will develop to 2027, alongside 13 strategic objectives for the Borough. Of particular relevance here is the objective to lead the way in high quality sustainable development that minimises the impacts of climate change. This will be achieved through maximising opportunities for implementing renewable energy technologies, maximising the efficient use of energy and water in buildings and managing waste effectively. The Core Strategy includes a number of policies to deliver this objective.
Policy CS22: Sustainable construction sets out the following requirements for new development.
New residential development on previously developed land will be required to meet:
It is expected that all relevant applications will have to provide the necessary information to demonstrate that this requirement can be met, via a 'pre-assessment report'.
New residential development is encouraged to meet the full requirements of each Code level, with particular encouragement for the material and ecology elements.
Where the scale, nature and location of a development would justify a higher Code level, the Council will negotiate with developers to achieve that because of the lower cost of developing such sites.
Code Level Mandatory Minimum Standards
In May 2014, the Department for Communities and Local Government issued a 'Code Addendum' to the Technical Guide November 2010, to reflect changes in Building Regulations. Code Level mandatory minimum standards are now as follows:
|Code level||Minimum % Improvment in Dwelling Emission Rate over 2013 Target Emission Rate (TER)||Maximum Indoor Water Consumption in Litres/Person/Day|
|Level 6||Net zero CO2 emissions||80|

Further guidance on meeting the Code for Sustainable Homes standards is provided in the Climate Change Supplementary Planning Document, adopted in December 2013. It is available to download here.
Further information on the Code for Sustainable Homes is avaible on the Council website and detailed information on the Code including the Code for Sustainable Homes: Technical Guide -Nov 2010, and Code Addendum (2014) is available on the CLG website. The site includes links to the Water Efficiency Calculator which is used as the assessment of indoor water use for New Dwellings and a Water Calculator tool which is available to download free.
Please note the glossary of the National Planning Policy Framework (NPPF) specifically excludes private residential gardens from the definition of previously developed land.
New residential development on greenfield sites will be required to meet the full requirements of Code for Sustainable Homes level 5.
The Council will consider a case based on evidence of viability if an applicant can demonstrate that the requirement for code level 5 cannot be met. This will be considered on a case by case basis.
It is expected that all relevant applications will have to provide the necessary information to demonstrate that this requirement can be met, by way of a 'pre-assessment report'.
The Council considers that achieving full Code level 5 will require careful design from the outset. Code design criteria should be incorporated from the earliest design phases of a project in order to understand the overall design implications. The CLG case study recommendations are that a Code assessor should be included in the project plans from the outset.
The build systems and the design approach should be integrated from the earliest design phases
Renewable energy technologies should be integrated into the overall design concept from the earliest design phases
The Council needs to be satisfied that applicants have given full consideration to meeting the Code requirements at the design stage. Meeting full Code level 5 is not something which can be retro-fitted once a building is near completion. In this regard, the Council expects the relevant information to be submitted for it to be considered as part of the validation process.
The Code for Sustainable Homes: Technical Guidance - frequently asked questions document compiled by the Building Research Establishment states that to achieve Code accreditation, the design stage assessment for the Code for Sustainable Homes is not compulsory. However the design stage assessment is recommended especially for developments where the developer is unfamiliar with the Code requirements and assessment process.
The document goes on to say that a design stage assessment is particularly helpful in demonstrating that the development design will meet the requirements of the desired Code level, and the targets. It allows for any changes required to achieve the desired level to be incorporated as early as possible, and with minimal cost and disruption. If the design stage assessment is not performed, and the post construction assessment highlights shortcomings, then the desired Code level may not be achieved and / or delays and additional costs may occur as a result.
On greenfield sites site where compliance with Code 5 is required, the Council will require applicants to produce the design stage assessment in order to validate applications. If any applications have been validated without this information, the Council will not be able to determine them without this information. As such further information will be required to enable the application to be determined.
Further guidance on on meeting the Code for Sustainable Homes standards is provided in the Climate Change Supplementary Planning Document, adopted in December 2013. It is available to download here.
The Council will encourage proposals for residential extensions to incorporate energy and water efficiency measures.
New non-residential development of 1,000sq.m. or more (gross) floorspace is required to comply with BREEAM very good standards. It is expected that all relevant applications will have to provide the necessary information to demonstrate that this requirement can be met, by way of a 'pre-assessment report'.
The Council will encourage proposals for non-residential developments of 1,000sq.m. or less (gross) floorspace to incorporate energy and water efficiency measures.
On developments where compliance with BREEAM very good standards is required, the Council will require applicants to produce a Pre-Assessment report in order to validate applications. If permission is granted conditions will be applied which require a Design Stage certificate to be submitted prior to commencement of the development and a Post-Construction Stage certificate to be submitted prior to occupation of the development. If any applications have been validated without this information, the Council will not be able to determine them until this information is provided.
Applications for developments with exceptionally high total energy consumption, such as large leisure facilities with a high heat demand or buildings with exceptionally high power/cooling loads (such as data centres), will be required to reduce the total carbon emissions from the development by 10% through the use of renewable energy measures on site.
It is anticipated that BREEAM 2011 for New Construction standards will be used to assess the types of buildings to which this policy applies (including those of less than 1,000sq.m gross floorspace if energy consumption is exceptionally high). Within the scheme, Ene04 'Low and zero carbon technologies' aims to reduce carbon emissions. As a means to, or in addition to, achieving a 'Very Good' rating, the proposed development should achieve at least 3 credits available in Ene04.
As part of BREEAM New Construction 2011, BREEAM Data Centres has been developed. Relevant developments will be required to achieve at least 2 credits in the Ene05 'Low or zero carbon technologies' category, as well as the minimum standards for a 'Very Good' rating.
Further guidance on these requirements is provided in the Climate Change SPD, available to download here.
Where it can be demonstrated that the standards set out in this policy cannot be met on site, permission will only be granted if the applicant makes provision for compensatory energy and COČ and water savings elsewhere in the Borough equivalent to the carbon savings which would have been made by applying this policy.
Combined Heat and Power (CHP) or other forms of low carbon district heating
All new development should consider the integration of Combined Heat and Power (CHP) or other forms of low carbon district heating in the development.
All new development in proximity of an existing or proposed CHP station or district heating network will be required to be connected to it unless it can be demonstrated that a better alternative for reducing carbon emissions from the development can be achieved. Details of the zones where connection will be required are set out in the Climate Change SPD, available to download here, and will be determined by factors such as the capacity of the existing CHP network, distance from it and physical constraints.
The evidence base which supports policy CS22 sets out the locations in the Borough which have significant potential for CHP or other forms of low carbon district heating networks. Subject to technical feasibility and financial viability, all development within these zones will be required to be designed and constructed to enable connection to the future network.
The Council is actively promoting electric vehicle charging points and has already provided a number of these in the Borough. These are of particular value when the electricity source is low carbon. Details of when new development will be expected to provide electric vehicle charging points or when a contribution towards public charging points will be require, are set out in the Climate Change SPD, available to download here.
Design and construction
The design of all new developments will be required to take account of layout, landform, orientation and landscaping to maximise efficient use of energy and adapt to the impacts of climate change.
The design of all new developments should facilitate the reduction of waste and the recycling and composting of the waste produced.
All developments should consider the use of sustainable construction techniques that promote the reuse and recycling of building materials. All development is encouraged to use responsible resourcing of materials and is encouraged to source materials locally. All new residential development is encouraged to meet the `materials' elements of the Code.
All applications for new development should include a completed copy of the Council's 'climate neutral development checklist' (with the exception of very minor development such as minor exterior alterations). The checklist is available to download from C-Plan.
Ecology and biodiversity
All development is encouraged to make biodiversity enhancements such as green roofs and bird and bat boxes. All new residential development is encouraged to meet the `ecology' elements of the Code.
Woking Borough Council expects proposals for all new development to comply with the policy requirements set out.
Development of renewable and low carbon energy provides one of the mainstays of the provisions set out in the Climate Change Act. The Act puts into statute the UK's targets to reduce CO2 emissions through domestic and international action by at least 80% by 2050 and at least 26% by 2020, against a 1990 baseline. The Act is supported by the UK Low Carbon Transition Plan which sets out the UK Government's strategy for climate and energy and proposes measures to reduce carbon emissions across all sectors.
Planning applicants will need to show how the proposed development will meet the low carbon energy requirements set out in Policies CS22 and CS23 of the Core Strategy. In order to help applicants gather all the necessary information for a planning application, the Council has developed 'C-Plan', a web-based service which allows developers to demonstrat and verify compliance with climate change policies.
C-Plan can help by:
The information submitted is automatically assigned to a Planning Officer, who will review the information. There is no charge for developers to use C-Plan, which is available here.
Follow the seven golden rules to successfully integrate sustainable energy in new development:
The Climate Change SPD provides in-depth guidance on meeting the requirements of policies CS22 and CS23 of the Core Strategy. It is available to download here.
The Energy Saving Trust (EST) website contains a lot of information on sustainable building. Housing professionals can access a range of technical services, publications and web tools to help them reach the maximum energy efficiency potential of their new build or refurbishment projects. The website has technical services guidance, web tools and project information for advice on improving the energy performance of new build developments. EST have produced a Fabric First guide, available to download. The guide looks at the degree to which improving fabric and services can achieve higher energy standards, as well as considering the cost effectiveness of incorporating these design improvements.
C-Plan is an online tool that has been developed to enable local planning authorities and developers to achieve fast and effective compliance with sustainable energy planning policies. Configured to meet specific local planning policies, C-Plan uses simple, easy to follow steps to quantify the energy and carbon emissions impact of your development and evaluate renewable/low carbon energy proposals.
