3 EXECUTIVE SUMMARY 1. Citycourt Developments Ltd has commissioned Envision Sustainability Ltd (Envision) to provide a Sustainability Statement, incorporating a BREEAM predictive assessment for the proposed new foodstore at White Cliffs Business Park off Honeywood Parkway in Dover. 2. Policy CP5 of the Dover Core Strategy relates to sustainable construction methods and sets a requirement that all new non-residential development over 1,000m² gross floor space should meet BREEAM Very Good standard (or any future national equivalent). 3. This sustainability statement demonstrates that a BREEAM score of Very Good is possible for the development proposals, when made against the 2014 New Construction Criteria relevant for a retail development. As explored within this statement, the scheme will deliver various sustainability benefits: The building s shell will be delivered to a very high standard of fabric energy performance; The contractor would register the site under the Considerate Constructors scheme, and take steps to reduce potential impacts arising through construction; Water leak detection will be installed at the building s boundary to prevent water leaks up to and within the unit; Materials will be procured from manufacturers that are accredited with an EMS; Thermal comfort analysis will be undertaken to ensure that the building can maintain comfortable conditions throughout the year, preventing it from overheating; Building materials will be selected which are highly rated against the BRE s Green Guide; The store will include cycle spaces for staff and customers to encourage cycling; Strict efficiency policies mean that store ordering levels are carefully monitored in order to minimise deliveries to two to three HGV deliveries per day. The returning HGV transports waste and recyclable material from the store to the nearest Regional Distribution Centre for processing. This ensures that the return journey is not a wasted trip and ensures our CO 2 emissions are as low as possible; Store heating and lighting will be controlled by a computerised Building Management System (BMS). This minimises energy consumption by adapting to external temperatures and lighting levels; The chilled food cabinets will incorporate night blinds which trap the chilled air and reduce energy consumption overnight; Refrigeration plant will have low Global Warming Potential emissions ratings and operates without the need for CFCs; All lighting in storage and staff welfare areas will be controlled with motion sensors, ensuring that electricity consumption is strictly controlled; The car park lighting is switched off overnight, and is controlled by a daylight sensor during trading hours

4 4. Should the Council impose a BREEAM condition on the scheme, it is recommended that no pre commencement BREEAM conditions are imposed on the scheme, as the internal details would not normally be finalised until after the enabling works commences, as well as the time taken by BRE to validate the assessment placing unreasonable constraints on the development programme. Instead, should BREEAM be secured by way of a condition this should only be required as a post occupancy planning condition, to be provided 6 months after first trading to enable evidence to be gathered and the BREEAM assessment to be validated by the BRE.

5 1 INTRODUCTION Overview 1.1 Envision Sustainability Ltd (Envision) has been appointed by Citycourt Developments Ltd to prepare a Sustainability Statement and BREEAM predictive assessment for the proposed new Lidl foodstore at White Cliffs Business Park, off Honeywood Parkway in Dover. The statement supports a planning application being made to Dover District Council for the construction of a new retail foodstore and associated car parking and landscaping works. 1.2 Full details of the proposals are provided within the Design and Access Statement which accompanies this application. 1.3 Policy CP5 of the Dover Core Strategy relates to sustainable construction methods and sets a requirement that all new non-residential development over 1,000m² gross floor space should meet BREEAM Very Good standard (or any future national equivalent). Lidl and Sustainability 1.4 Lidl as a responsible retailer is committed to delivering as sustainable a development as possible. The proposed store will meet Lidl s high sustainability standards which are intended to minimise environmental impact over the lifetime of the store. 1.5 The requirements set out in Lidl s Corporate Specification for the design and construction of new foodstores serves to ensure that environmental impacts are limited in accordance with the requirements of relevant planning policy. This specification has been written and updated to reflect the requirements of BREEAM New Construction 2014.

6 2 THE PROPOSED DEVELOPMENT 2.1 The development will deliver a new neighbourhood foodstore with associated carparking. The development has been designed as a modern high quality building incorporating a fully glazed shopfront that will provide a gateway feature at this entrance to White Cliffs Business Park. 2.2 Further details in the extent of the scheme is available within the Design and Access Statement and accompanying scheme plans which have been prepared in support of the planning application. Figure 1 shows the proposed site layout. 2.3 The building is to be constructed on two storeys with a rectangular footprint and the main entrance doors located to the far right hand side. The northern elevation and shop front will be fully glazed, with the rest of the elevations a mixture of Alucobond rainscreen cladding and render. Figure 1 Proposed Development Approach to BREEAM 2.4 Policy CP5 of the Dover Core Strategy relates to sustainable construction methods and sets a requirement that all new non-residential development over 1,000m² gross floor space should meet BREEAM Very Good standard (or any future national equivalent). BREEAM assessments provide a sustainability rating for non-domestic buildings by giving consideration to a range of criteria. This includes principles of Management, Health & Well Being, Energy, Transport, Water,

7 Materials, Waste, Land Use & Ecology and Pollution. Innovation credits are also available, representing new or exemplary performance in a specific sustainability issue. 2.5 This predictive assessment is made against the BREEAM New Construction criteria (2014 v3), as a fully fitted development. Target Level 2.6 As required by Policy CP5, the target for the proposed works is Very Good which is equal to or greater than 55. BREEAM scoring bands are shown below. Target Score UNCLASSIFIED <30 PASS GOOD V GOOD EXCELLENT OUTSTANDING Mandatory Credits 2.7 The majority of credits within BREEAM New Construction are tradable, meaning that there is some flexibility to how a specific target can be achieved. BREEAM also includes a number of mandatory standards, which must be met in order to achieve Very Good. These credits are shown in the table below. The predictive assessment makes reference to these where appropriate. BREEAM issue Very Good Ene 02 Energy Monitoring One Credit Sub Metering Wat 01 Water Consumption One Credit Wat 02 Water Monitoring Criterion 1 Mat 03 Responsible Sourcing Criterion 1 LE 03 Minimising Impact on Ecology One Credit Approach 2.8 A BREEAM predictive assessment has been undertaken for the proposed scheme. The main findings of the assessment are discussed in further detail in the following sections, including details of the efforts that will be taken to achieve individual credits. The assessment is based on an evaluation of site constraints, liaison with the design team, an understanding of Lidl s corporate specification for new foodstores, and on the assumption that various measures and activities can be adopted in detailed design and construction. The BRE s predictive assessment estimator summary is provided in Appendix 1.

8 2.9 The process is iterative, and involves an initial assessment of the site and proposals, before considering additional sustainability measures to enhance the environmental performance of the scheme most practically and cost effectively. Assessment Scope 2.10 In order to complete the assessment, a number of parameters need to be fixed. These define the criteria, and effectively remove erroneous credits for the assessment procedure. The following scope has been selected for this purpose. Parameters Building Type Building Type Sub Group Project Type Heating and Cooling Commercial Scale Refrigeration Internal / External Soft Landscaping Lifts / Escalators Vehicle Wash Retail Retail A1 New Construction Yes Yes Yes No No 2.11 The following section provides a summary of performance and key issues of the building against the BREEAM Criteria.

9 3 BREEAM - MAIN FINDINGS Predictive Assessment Summary Rating 3.1 The BREEAM predictive assessment demonstrates that a score of Very Good is technically achievable for the development, albeit that the performance is marginal over the 55% threshold. It is normal practice that during the more detailed design development further analysis is given towards BREEAM with a view to maximising the achievable score. 3.2 The scoring summary is shown overleaf and provided in Appendix 1.

11 4 PREDICTIVE ASSESSMENT PROPOSALS Management 4.1 BREEAM encourages good practice both in construction site management and for the operation of the building. Lidl s corporate specification requires the implementation of a series of procedures as standard practice when managing new construction and refurbishment projects. These limit the impacts of construction projects on the neighbours and the surrounding area. Construction Management 4.2 In terms of construction management, the following would be undertaken, delivered via the proposed Construction Management Plan: The Principal contractor would registered the project with the Considerate Constructors Scheme and achieve a score 35 or more; Energy use would be monitored during construction using the BREEAM reporting tool, based on kwh consumption per 100K of project value. Water use would be monitored and recorded during construction. 100% of the timber would be sourced in accordance with Government Timber Policy. The contractor will hold an EMS. A sustainability champion will oversee the setting of targets for the project. The building fabric will be commissioned prior to handover of the unit to the tenant. Operational Management 4.3 Lidl will produce a Building User Guide relevant to the proposed development, which will be given to the facilities management team upon building completion. This will provide an understanding of the principal sustainability design features incorporated and how to minimise impacts during operation. Health and Wellbeing 4.4 BREEAM 2014 includes various credits which assist to make buildings accessible and promote health. It includes standards for natural daylight, the control of glare, lighting levels and occupant controls. More broadly credits are awarded for adopting security standards which align with the Secured by Design. Artificial lighting levels and thermal comfort 4.5 New internal and external artificial lighting will be required as part of the works. Lighting standards for the external works will be in accordance with BREEAM and internal lighting will meet to relevant CIBSE standards including the CIBSE Code for Lighting 2009 for internal lighting. 4.6 In due course dynamic energy modelling will be used to assess energy demands and emissions for the building. This will be carried out at detailed design to ensure that appropriate internal comfort

12 conditions can be maintained for building occupants. This will be demonstrated using the CIBSE AM11 standard. The internal comfort levels will be in accordance with temperature ranges recognised by CIBSE Guide A. Security 4.7 The Lidl Corporate Specification requires the main contractor, as part of their initial design work, to liaise with and seek advice from the local police Architectural Liaison Officer on designing out the opportunity of crime, in accordance with the principles and guidance of Secured by Design. Energy 4.8 BREEAM credit Ene 01 requires that improvements are made against 2013 building regulations. A triple metric calculation methodology is used in BREEAM 2014 and promotes a 'fabric first' approach to building design. Credits are awarded based on the following triple metric hierarchy: Heating and cooling energy demand (influenced by factors such as building fabric performance and air permeability); Primary energy consumption (influenced by the efficiencies of building services systems and energy generation and transmission); CO 2 emissions (influenced by factors such as distribution efficiency and fuel source/renewable energy technologies). 4.9 The building's heating and cooling energy demand is influenced primarily by fabric efficiency and air tightness. In accordance with Lidl s corporate specification, the u-values for all envelope parts of the building will be as follows:- Windows / shop front/ lobby Alucobond façade Brickwork external walls Ceiling/roof Floor 1.10 W/m²K 0.25 W/m²K 0.25 W/m²K 0.19 W/m²K 0.25 W/m²K Thermal Construction 4.10 During detailed design consideration will be given to the thermal performance requirements of the unit. A thermal model of the proposed design will be developed, using software selected and applied in accordance with CIBSE AM11 Building Energy and Environmental Modelling. The software will be used to carry out a simulation of the detailed design, with a full thermal dynamic analysis Consideration has also been given to air leakage. The design air permeability rate will be lowered as far as practical. The Lidl corporate specification requires the APR to be reduced to at least 4 m 3 /h/m 2.

13 Efficiency measures 4.12 Energy efficiency measures will be incorporated in the design. Store heating and lighting will be controlled by a computerised Building Management System (BMS). This minimises energy consumption by adapting to external temperatures and lighting levels. The chilled food cabinets will incorporate night blinds which trap the chilled air and reduce energy consumption overnight. All lighting in storage and staff welfare areas will be controlled with motion sensors, ensuring that electricity consumption is strictly controlled. The car park lighting is switched off overnight, and is controlled by a daylight sensor during trading hours. Transport 4.13 BREEAM awards credits for accessible developments that make provision for sustainable forms of transport The proposed site is well placed to encourage access by sustainable modes of transport, being within walking and cycling distance of the existing residential settlements in Whitfield and the commercial and retail facilities to the west of the site. There are good pedestrian and cycle facilities along Honeywood Parkway providing direct routes to White Cliffs Business Park and Whitfield The site is also well places in terms of public transport, in particular bus services, with bus stops located immediately adjacent to the southern perimeter of the site on Honeywood Parkway. There are four services an hour operating from these bus stops Monday Saturday and two services an hour on Sundays Pedestrian access to the store will be from a dedicated pedestrian route from Honeywood Parkway. There will be crossing provided within the site to ensure a safe and direct route for pedestrians to the store. The proposed vehicular and cycle access to the site will be via a new arm at the existing Honeywood Parkway roundabout BREEAM Credits are also available if a compliant Travel Plan and cycle storage are in place. Lidl will prepare a Travel Plan for this proposed site, and suitable cycle storage is proposed as part of the development. Water Use 4.18 Under BREEAM 2014 credits are awarded for reductions in water use, measured against a percentage reduction from a notional baseline. The building would include low water fittings compliant with BREEAM Lidl will install a leak detection system for the unit on the buildings main water main. This will provide leak detection capability at the buildings boundary, and within the floor slab of the unit. In addition, as included in Lidl s corporate specification, solenoid valves will be installed on the water supply to each toilet area in the building to control the flow of water.

14 4.20 The new landscaping proposed will be watered manually from a bowser, particularly during warmer times as plants establish. The landscaping will not require any formal irrigation strategy to be put in place. Materials 4.21 The materials section within BREEAM 2014 awards credits for the specification of sustainable major building elements which are highly rated under the Green Guide to Specification. BREEAM 2014 also awards additional credits if life cycle carbon emissions are considered in material specification, through the application of Environmental Product Declarations. Credits are also available for durability studies. Procuring Materials Responsibly 4.22 Throughout further stages of design following the appointment of a contractor, consideration will be given to the responsible sourcing of main construction materials. For example, material suppliers will preferentially hold an Environmental Management System (EMS), where possible accredited to ISO At this stage it is assumed that the main building elements including the roof, glazing, and cladding can be procured from suppliers that have a robust EMS in place All timber will be FSC and procured in accordance with the UK Government s Timber Procurement policy. Waste 4.24 With regards to construction and demolition waste, prior to commencement of works, targets will be established within the Site Waste Management Plan which accords with the UK Waste Hierarchy. 90% of non-demolition waste (by tonnage) will be diverted from landfill. A target for waste generation 6.5 tonnes per every 100m 2 of floor area will be established for construction waste. Waste will be managed in accordance with the requirements of Lidl s corporate specification. Land Use and Ecology 4.25 BREEAM awards credits for locating development on areas of low ecological value. The site of the proposed development is currently greenfield but is used for mono agriculture and there are no ecological features to preserve, therefore it is considered to be of limited ecological value The incorporation of landscaping and ecological enhancements into a scheme. A suitable landscaping strategy will be developed which incorporates the specification of native species where feasible. Pollution 4.27 BREEAM awards credits for design measures which reduce pollution from the building. The section covers a number of areas including impacts from refrigerants on level of greenhouse gas

15 emissions, NOx emissions to reduce pollution of the local environment, SuDS, light pollution and noise. The external lighting design will follow the ILE guidance on the Reduction of Obtrusive Light. Refrigeration plant will have low Global Warming Potential emissions ratings and operates without the need for CFCs The site is in a low risk for flooding. To achieve credits in this section the drainage details will be expected to achieve greenfield run off rates and be protected from sources of pollution prior to any discharge off site to nearby water courses. A drainage strategy has been included with the application which confirms the strategy.

16 5 CONCLUSION AND RECOMMENDATIONS 5.1 Citycourt Developments Ltd and Lidl are together committed to ensuring the development s construction is environmentally sustainable. They are therefore committed to incorporating reasonable sustainable design and construction measures. The BREEAM predictive assessment demonstrates that a score of Very Good is achievable for a development, meeting the requirements of Policy CP5 of the Dover Core Strategy. 5.2 The main attributes of the development that will support BREEAM and Policy CP5 are as follows: The building s shell will be delivered to a very high standard of fabric energy performance; The contractor would register the site under the Considerate Constructors scheme, and take steps to reduce potential impacts arising through construction; Water leak detection will be installed at the building s boundary to prevent water leaks up to and within the unit; Materials will be procured from manufacturers that are accredited with an EMS; Thermal comfort analysis will be undertaken to ensure that the building can maintain comfortable conditions throughout the year, preventing it from overheating; Building materials will be selected which are highly rated against the BRE s Green Guide; The store will include cycle spaces for staff and customers to encourage cycling; Strict efficiency policies mean that store ordering levels are carefully monitored in order to minimise deliveries to two to three HGV deliveries per day. The returning HGV transports waste and recyclable material from the store to the nearest Regional Distribution Centre for processing. This ensures that the return journey is not a wasted trip and ensures our CO 2 emissions are as low as possible; Store heating and lighting will be controlled by a computerised Building Management System (BMS). This minimises energy consumption by adapting to external temperatures and lighting levels; The chilled food cabinets will incorporate night blinds which trap the chilled air and reduce energy consumption overnight; Refrigeration plant will have low Global Warming Potential emissions ratings and operates without the need for CFCs; All lighting in storage and staff welfare areas will be controlled with motion sensors, ensuring that electricity consumption is strictly controlled; The car park lighting is switched off overnight, and is controlled by a daylight sensor during trading hours 5.3 It is material to note that for the White Cliffs Business Park permission (ref Dov/15/00815); BREEAM was not made a formal planning condition of the project, as it was considered inappropriate for the scale of project proposed. Should the Council choose to impose a BREEAM condition on the scheme, it is recommended that no pre commencement BREEAM conditions are imposed on the scheme. It is important for Citycourt Developments Ltd to commence enabling

17 works on site during the period when the internal layout designs are still being finalised and as such the full suite of evidence required to sign off the BREEAM Design Stage assessment would not be available prior to commencement on site. In addition, BRE are currently taking between 4-6 weeks to validate a BREEAM assessment and supply interim certification. This period, which is outside of the control of both the project team, and as such, could cause unreasonable delays to the project programme. It is recommended instead, should BREEAM be secured by way of a condition, this should only be required as a post occupancy planning condition, to be provided 6 months after first trading to enable evidence to be gathered and the BREEAM assessment to be validated by the BRE. Suitable wording of such a condition could be: The premises shall not be occupied until a copy of an interim BREEAM certificate in accordance with the BREEAM Sustainability Standard demonstrating compliance with a minimum standard of BREEAM Very Good rating has been submitted to and receipt acknowledged in writing by the Local Planning Authority. No later than 3 months after the building is occupied a copy of a Final BREEAM Certificate in accordance with the BREEAM Sustainability Standard following a post-construction stage review carried out by a licensed assessor shall be submitted to and receipt acknowledged in writing by the Local Planning Authority, demonstrating that the development has attained as a minimum the standard of Very Good.
