Carbon & Energy
For the delivery of Net Zero Carbon School and community buildings applicants should:
• Capitalise on energy efficient and low carbon heating sources that do not use fossil fuels
• Utilise renewable energy sources such as solar panels PV cells to ensure a low operational carbon demand. Large planes of flat/ shallow pitched roofs offer plentiful opportunities for Solar PV capture and on site energy offsetting, as well as large playing field amenity space provision for the potential to use Ground source heat pumps
• Use low embodied carbon materials that are highly sustainable, renewable or made of high recycled content such as timber, GGBS concrete and recycled steel
• Make reference to how materials are being manufactured, procured, transported and constructed onsite to reduce Upfront Carbon figures. Questions should be asked about what are the big ticket carbon saving materials being used, their specifications & strategies for future repair, maintenance & replacement to reduce in-use embodied carbon
• Design simple building forms and thermal fabric: Applicants should provide Form Factor calculations with thermal lines on plan & section drawings
• Consider windows locations and sizes: based on facade orientation, natural light optimisation and inclusion of shading devices, where appropriate
• Be naturally ventilated buildings and dual aspect as a priority, with MVHR where appropriate
Water
The primary focus is to construct buildings to be climate resilience, and minimise potable water use to reduce pressure on water demand. School and community building schemes should demonstrate:
• Reduced appliance and fitting flow rates to minimise water use and use of Waste Water Heat Recovery appliances
• Evidence of blue / green infrastructure and Sustainable Urban Drainage Systems that capture stormwater and mitigate flooding
• Evidence of permeable hard landscape surfaces
• Provision of rainwater collection such as water butts and Grey water recycling measures
• AECB Water Standard Volumes 1 + 2 provide further guidance for non-domestic buildings
Waste & Materials
The primary focus is to construct economy principles, promote materials and opportunities domestic waste streams. Schemes
• Appropriately sized, easily storage provision for recycled waste streams
• Specify reused or recycled materials in dwellings and
• Demonstrate design deconstruction or adaptability and Offsite Construction school term/calendar disruptions
Materials
construct schemes with circular promote sustainable and healthy for occupants to minimise Schemes should evidence: easily accessible and secure recycled food waste and general
recycled and responsibly sourced and landscape treatment for material efficiency, adaptability of homes with DfMA / MMC methods to minimise disruptions and on-site pollution
Health & Wellbeing
In addition to supporting sustainability goals, school and community building designs promote the health and wellbeing of the occupants, staff and children. The primary focus is to develop these facilities within healthy neighbourhoods with active travel and low carbon and pollution infrastructure. Such developments should incorporate:
Transport
• EDC Sustainable Travel Strategy requirements and measures
• Mobility hubs within 400m of front doors to provide building users with an interchange for sustainable modes of transportation to take them further afield. A mobility hub should provide connection between at least two types of sustainable transportation such as bus-to-train or bike-to-bus
• Car Clubs to promote reduced car quantities and pollution
• EV charging points to individual buildings and car hub/parks locations as specified
• A clear public realm design hierarchy of pedestrian, cycle and public transport routes
• Secure Bicycle storage facilities
Building Quality
• Align design proposals with the Design for Ebbsflet Guidance and Community Buildings Design Criteria
• Maximise natural daylight and dual aspect designs for natural ventilation
• Demonstrate design and specification of healthy materials with low emission of Volatile Organic Compounds via EPD datasheets
• Optimise dwelling orientation, density, massing and room locations to maximise natural daylight and limit overshadowing. Allow a distance of 1/1.5 times the building height between buildings
• Demonstrate summer solar gain and overheating mitigation with shading devices and projecting balcony locations
• Specify robust materials that weather & wear well
Natural Environment
The primary focus is to construct schools and community buildings and their surroundings with green infrastructure that contributes to climate resilience and provides opportunities to enable occupants to connect with nature and make sustainable lifestyle choices. Applicants should provide evidence of:
• Diversity of native and drought resistance species of planting
• Creation and provision of habitats in the landscape
• Soft landscaping and Tree Canopy Cover strategies in alignment with EDC’S Public Realm Strategy
• Connect new public realm to existing
• Provision of food growing facilities
• Adoption of minimum 10% Biodiversity Net Gain and target 0.4 or greater Urban Greening Factor opportunities

Community Engagement
Community Engagement
Accessibility
Project has facilitated co-design events early in the design process to up-skill the community on design, and enable them to engage in the codesign of the project.`
Project has utilised a digital engagement platform throughout the design process to provide a portal for all briefing and community engagement activities, and to provide feedback on community proposals and ideas.
Project has included an access consultant to enable best practice accessibility within the project.
Accessibility
Inclusive Growth and Social Value
Arts and Culture
For Public Buildings, the project has applied the public building section of the London Legacy Development Corporation’s Inclusive Design Standards.
Applicants have considered how the project can support the delivery of the Ebbsfleet Inclusive Growth Strategy, and engage with EDC’s Inclusive Growth Manager to identify opportunities, and establish commitments during the pre-application process.
Design teams has reviewed the Ebbsfleet Public Art Strategy, and integrated the Ebbsfleet public art principles into the project.
