Meridian Water has an ambition to be an exemplar sustainable development. The Environmental Sustainability Strategy sets out a vision and framework for achieving that ambition. The vision is founded on three core goals to address the three most significant global environmental challenges: climate change, mass extinction of species and resource depletion.

Carbon Positive To meet Enfield’s climate commitments Meridian Water will be carbon neutral by 2030, and strive for carbon positive over the whole life of the development. This means Meridian Water will minimise its embodied carbon in construction, use sustainably sourced materials, use only zero carbon power through a combination of on-site generation and renewable power purchase agreements, foster active travel and support high-quality, healthy and low carbon lifestyles.

Environment Positive The natural environment will be restored to promote a radical increase in biodiversity. Continuous green and blue networks will link Meridian Water with the wider Lee Valley Regional Park. The public realm, buildings and streets will be designed to create a safe and welcoming environment and comfortable micro-climate, that is resilient to climate change and supports active and healthy lifestyles.

Zero Waste and Circular Waste will be eliminated through adoption of circular design principles, sharing networks and eco-innovation. Meridian Water will be a regenerative built environment where whole buildings, materials and components will be retained at their highest value for as long as possible.

The framework follows an approach based on Kate Raworth’s ‘Doughnut Economics’, which proposes that true prosperity is only achieved when certain fundamental social needs are met, without exceeding the ceiling of ecological limits. The ‘thriving and innovative economy’ is the area within which inclusive and sustainable development takes place; here, the economy is seen as way of redistributing social and environmental value, rather than a goal in itself.

This section summaries the development and sustainability context for Meridian Water, including locating it within the regulatory and policy framework that is underpinned by the Climate Emergency. It then sets out the environmental sustainability vision for Meridian Water.

. Meridian Water

Meridian Water is one of London’s largest regeneration opportunities. Located between Edmonton, Tottenham and Walthamstow, it is a unique site on the cusp of inner London and neighbouring the Lee Valley Regional Park, in a landscape rich in wildlife as well as industry. The site directly borders the North Circular, and with the new Meridian Water station on the planned Crossrail 2 route, it enjoys excellent rail and road links to Central London and its surrounding airports. Building on carefully crafted placemaking pillars and best practice design principles Meridian Water will be at the forefront of sustainable development worldwide and emerge as a distinctive, inclusive place, designed to nurture economic, environmental and social sustainability. Local people will be the principle beneficaries of Meridian Water, which will deliver up to 10,000 new homes, 6,000 jobs and over 10 hectares of new parkland and vibrant public realm over the course of the 25-year mixed-use development. This will make a significant contribution to lifting Edmonton out of the 20% most deprived wards nationally. The Council is taking control of the vision for Meridian Water and overseeing its delivery. Over the past ten years Enfield Council has secured local planning policy changes that have paved the way for residential-led development at Meridian Water, while assembling a significant land holding Aerial views of the existing Meridian Water site. to enable the comprehensive masterplanning, design and delivery of the vision. The Council has commenced cleaning contaminated land (a legacy of former industrial uses), delivered a new railway station in partnership with Network Rail, achieved planning consent for over 3,000 homes and worked with existing and new partners such as Vibrations Group to deliver an ambitious ‘meanwhile’ programme of uses on site. In 2021 delivery of the first phase of homes will start on site, followed swiftly by a second phase. These two projects, in partnership with Vistry, will deliver over 1,000 homes, of which at least 50% will be affordable and earmarked for residents in the borough. Meridian Water site location. New Meridian Water station, opened in June 2019.

Meridian Water Environmental Sustainability Strategy, V1, September 2020 7 Sustainability Framework and Goals

Delivering the vision will require a systematic approach and solutions that achieve multiple sustainable outcomes. We have framed the sustainability objectives around the following six core goals:

• Carbon Positive • Environment Positive • Zero Waste and Circular • Employment and Skills • Strong Community • Health and Wellbeing

The environmental goals respond to the three most significant global environmental challenges: climate change, mass extinction of species and resource depletion.

The social goals are guided by the understanding that Meridian Water sits in an area of high social deprivation and will contribute to raising socio-economic and health outcomes of local people. Meridian Water will be designed to create meaningful employment, high-quality education opportunities and support healthy and empowered citizens.

This approach is based on Kate Raworth’s conceptualization of ‘Doughnut Economics’, which proposes that true prosperity is only achieved when certain fundamental social needs are met, without exceeding the ceiling of ecological limits. The ‘thriving and innovative economy’ is the area within which inclusive and sustainable development takes place; here, the economy is seen as way to create social and economic value in a way that also preserves and regenerates the environment.

Together, these goals provide a framework against which objectives and requirements can be set and progress monitored and reported. The next sections outline a series of principles and approaches through which the key goals can be met. We then present a series of detailed objectives and requirements for the environmental themes, which are the focus of this strategy.

The Circular Economy is a model for retaining resources Numerous approaches can be taken to design out waste, and the use of secondary, recycled and reused materials to in use and at their highest value. The London Waste and wherever possible. At a strategic level, these include ensuring reduce consumption of virgin materials. Recycling Board estimates that the transition to a Circular that the investment in materials and buildings delivers Economy could contribute between £3 billion and £5 billion maximum benefit, high utilisation of spaces throughout the There may also be an opportunity to establish a local offsite in growth for London by 2036 and create as many as 12,000 day, through colocation of services and spaces that can be construction facility and skills academy. This could enable jobs. Developing and implementing a circular strategy in used in different ways. Buildings should be designed for their the manufacture of prefabricated components for modular Meridian Water can support broader ambitions including job whole life cycle, so they are adaptable to changing needs. construction (MMC). Modular construction can reduce creation and economic development. This means design for low maintenance, adaptability and material waste, reduce programme lengths and provide disassembley.

Meridian Water Environmental Sustainability Strategy, V1, September 2020 16 Policy Context

Implications for Meridian Water While the policies reviewed above already set high standards for sustainable development, the aspiration of Meridian Water is to go beyond policy, by achieving a zero waste, and carbon and biodiveristy positive development.

It is much easier to set the vision and targets, than it is to deliver them in practice. Meridian Water will need to challenge many of the current norms of development, policy baselines and business-as-usual approaches. To be the greenest development in London and achieve climate commitments, a strong delivery strategy will be required. This will include:

• setting a communal governance framework, with clear roles, responsibilities, and accountability structures, • facilitating cultural shifts through deep engagement, to ensure there is widespread buy-in to the vision and goals, • capturing true whole life value by moving beyond traditional financing models, • enabling innovation within the supply chain, • effective use of accreditation, and • strong project management processes including design briefs and reviews, procurement and engagement, risk and change management, oversight, audit and monitoring, sign off and approvals at each stage of the programme.

A strategy for delivering the vision is presented in the ‘Implementing the Vision’ chapter. The next section sets out the detailed objectives and requirements for a sustainable Meridian Water.

The objectives and requirements Strategic Infrastructure Works tender information. These should be reviewed, tailored and embedded in individual requirements should be referred to in addition to this meanwhile project briefs strategy for all Strategic Infrastructure Works projects.

Residential development Meridian Water is a residential-led scheme and the majority of the objectives and requirements set out in this strategy will be applicable to residential development from a phase and building scale through to individual units.

The requirements are applicable to all housing typologies and types including units for private sale or rent, affordable housing, purpose build-to-rent schemes, student housing, co-living, intergenerational and older living schemes.

Given the high level nature and broad scope of the objectives and requirements it will be important that they are reviewed, tailored and embedded in individual residential project briefs.

Meridian Water Environmental Sustainability Strategy, V1, September 2020 38 Social value and co-benefits

This section sets out how adopting this sustainability strategy will deliver value that goes beyond purely environmental benefits. Meridian Water will be home to engaged and empowered citizens, who benefit from high-quality education opportunities and participate in meaningful employment. Community and social value will be enhanced as people lead active lifestyles within a clean and healthy environment, which is well connected, both physically and digitally. Why does this matter in the east of Enfield?

There is an intrinsic link between environmental sustainability and building social value. Taking an integrated approach to applying the three thematic goals set out in the previous sections (carbon positive, environment positive, zero waste and circular) will deliver multiple benefits; this is the most effective way to address the specific challenges found at this site. 1 1

April 2020 Meridian Water Masterplan V02 1 Open Space Value 8/48 Social themes and objectives

In successful developments of this scale, value is created on three levels: what you build (the design), how you build (construction) and operation (in use over whole lifetime). The potential for impact is greatest at the earliest stages of the project (ideally pre-RIBA 0). A clear Social Sustainability Strategy should be developed, based on a needs-based approach. The Sustainability Strategy will set the ‘social foundation’ for the Meridian Water development and could include the themes and KPIs set out below.

As part of the Social Sustainability Strategy, the Council should put in place framework for monitoring these co-benefits, over time. As part of this, it may be beneficial to use the Social Return on Investment (SROI) methodology to set specific targets and monitor progress as the scheme is designed, constructed and inhabited. A key consideration when establishing a framework and setting targets is to ensure that there are at least some KPIs that can be monitored as the project develops, rather than relying on post-completion data.

To deliver the vision, the team need to fully usual approach. At this point, further engagement with including national, understand what the targets are, and the design process contractors and the supply chain should take place, Review of planning context: regional (London) and local including anticipating needs to allow sufficient time for testing, innovation and including through participation in design reviews, to bring any future changes to policies that may impact iterative design development.

Tenders should also include the highest environmental requirements, including an ISO 14001 project management system, and best practice certification and acredditation processes (e.g. BREEAM, FORS, Considerate Constructors etc.).

All social and environmental commitments should then be incorporated into procurement contracts, with appropriate incentives included to encourage innovation and best practice. Tenderers should also be invited to propose how they will carry out meaningful community engagement

Meridian Water Environmental Sustainability Strategy, V1, September 2020 55 Step 4: Construction and commissioning

Leadership and supply chain management Optimising performance in use Contractors and their supply chain are crucial to ensuring There is a known performance gap between design and Construction: Key Actions that best practice in sustainability is achieved. Most of actual environmental performance of buildings, resulting in the innovation in new products, construction processes greater than necessary energy consumption, and reduced and systems comes from the supply chain (see diagram comfort and satisfaction for occupants. Embed Code of Construction Practice Carry out regular monitoring and audit on p.53). The supply chain responds best to clear and (CoCP): against commitments set out in the CoCP, so that well-defined briefs. Having engaged the supply chain An effective comissioning and handover process, in line expectations for the way the contractor will operate early and challenged them to bring their best ideas to with Soft Landings, is essential, to reduce the performance are met, including around social, environmental and the development, the challenge now is to ensure these gap and deliver better project outcomes. This means transport requirements. innovations are embedded and delivered. being clear from the outset what information is required for commissioning, handover, facilities management including Here, the CoCP is a useful tool in holding construction maintenance, and to meet any requirements of Building Environmental Management System (EMS): Contractors to set up and operate a rigorous teams accountable for delivery of all aspects of the Information Modelling (BIM). It is also important that Environmental Management System, to meet the sustainability strategy. While the Development Director procurement models allow for greater involvement with, CoCP requirements, including minimising how its should be responsible for meeting the requirements directly, and maintain a consistent ‘golden thread’ between, design operations affect the environment and comply with this will only be achieved with support from a named head teams and contractors during handover and beyond. all performance standards, policies and regulations. of environment within the construction team.

Getting this right from the get-go is therefore essential. Project Directors are often very risk averse, so steps Follow the Soft Landings process should be taken to adress this, through allowing sufficient Soft Landings: during construction, commissioning and handover, time in individual project progammes for viability testing to minimise the energy performance gap and and feasibility studies, as well as pilot projects to test out deliver buildings and infrastructure which is usable, innovations. maintainable and energy and resource efficient. The requirements of this strategy will not be met if a Establish a management, ‘business as usual’ approach to construction is taken. Project Management: reporting and audit process and provide regular Innovative materials and fabrication methods will need to be updates on performance against the requirements used; this relies on appointing and managing construction of this strategy, the CoCP and any other contractual teams with the right attitute, as well as experience of low requirements. carbon construction techniques.

While taking this approach, it is likely that the need for Delivering the infrastructure As development progresses, it will be important to update projects and initiatives which fall outside the overall These projects mostly fall under the general area of policies and set out requirements for developers so that scope of the development, but which are required to meet infrastructure (alongside innovation like soil remediation, specific neighbourhoods and individual buildings are the sustainability vision, objectives and requirements, demolition reuse and recycling etc.).

Site area: 64 ha No of dwellings: 10,000 Av. density: 156 dph Public green/blue space: 25% PTAL: 3-6 Completion: 2031

Sustainability and the environment were at the heart of London’s successful bid for the 2012 Olympic and Paralympic Games. Key to the successful delivery of the greenest games ever were new standards for environmental performance and regeneration, and legal, contracting and procurement systems that promoted sustainability and innovation as part of creating a culture of collaboration, learning and partnership.

NEC contracts that took a value creation approach to development and required very high sustainability standards. Most importantly, tenders involved several engagement events in which the sustainability goals were set out and design and sustainability criteria were given a very high weighting in the procurement process (70%).

Five new distinct residential neighbourhoods are being created around the Queen Elizabeth Olympic Park that will provide 10,000 new homes. In addition to The Queen Elizabeth Olympic Park itself substantial amounts of public green space has been provided within new residential areas, with a focus on creating biodiversity rich spaces.

The regeneration project is providing employment space for 25,000 new jobs. The commercial strategy places a strong emphasis on working with existing communities to ensure they benefit from economic development, and support new and existing creative industries.

Site area: 13.4 ha No of dwellings: 5,000 Av. density: 373dph Public green/blue space: 25% PTAL: 6 Completion: 2025

The regeneration of Elephant and Castle is aiming to be one of the most environmentally sustainable urban regeneration projects in the world. They have focused their sustainability strategy on three key themes: climate positive, green spaces and sustainable transport.

The development will be climate positive when it completes in 2025. The area is one of ten low carbon zones identified by the Mayor of London tasked with local production of cleaner better value energy to fuel local households and businesses; CHP will deliver zero-carbon heating. New homes will be at least 35% more energy efficient that current regulations and will include 15 accredited Passivhaus homes.

Elephant Park has a commitment to create central London’s new ‘green heart’. Over 11 acres of new and improved public spaces will be delivered, in addition to urban greening elements.

Regeneration is designed to support and encourage sustainle transport: prioritising walking and cycling, access to public transport and electrification of vehicles.

The environmental sustainable placemaking principles are embedded in The Elephant and Castle Supplementary Planning Document, produced in 2012, which will guide the development over the next 15 years, ensuring that regeneration is coordinated and sustainable.

Site area: 52 ha No of dwellings: 5,500 Av. density: 106 dph Public green/blue space: 45% (12% green + 33% blue) PTAL: 4-6 Completion: 2028

The regeneration of Woodbury Down is committed to enhancing the natural environment and has capitalised on the area’s abundant wildlife and existing reservoirs to create a new urban nature reserve as well as a multitude of parks and squares. The development also promotes biodiversity through the incorporation of urban greening elements such as living roofs and natural swales as part of the SUDS.

Master planning for Woodberry Down has focused on creating a sustainable community, with large and improved public open spaces as well as new community facilities.

All new homes will be highly energy efficient. Heating and hot water is supplied through an efficient communal heating network and a CHP system. PVs on roofs supply the development with renewable energy for communal areas.

All homes have with water efficient fittings and rainwater harvesting systems are incorporated in the drainage design to reduce the need for mains water to irrigate planting across the development.

The development is designed to support and encourage sustainle transport: prioritising walking and cycling, access to public transport and electrification of vehicles.

Woodbury Down is a useful precedent for working with Thames Water, local communities and stakeholders to deliver unique and valuable green/blue infrastructure that becomes the heart of the development. Key to the Woodbury Downs regeneration has been the creation of an urban nature reserve, the Woodbury Wetlands.

This plan sets out the action we will take in each of these areas. The first area – the Council’s operations – sets out how we will reduce the Council’s own emissions to zero and we have set targets for how we will achieve this. This section covers how we will reduce carbon emissions the Council creates from the operation of our own buildings Reporting our performance (including our libraries, civic centre, other council buildings and our maintained schools); from the goods and Buildings services we purchase; and from how our staff commute to work and travel during the working day. We will review performance and publish our progress on an annual basis, The remainder of the plan focuses on the actions we intend to using the key performance indicators set out in our plan.
