What is a Sustainability Statement?
So – what is a Sustainability Statement, and how are they different to Energy Statements and SAP Calculations? Essentially, a Sustainability Statement is a comprehensive document that covers all aspects of the environmental impact of a planned development. While Energy Statements, SAP and SBEM Calculations are only concerned with energy, a Sustainability Statement includes everything from:
- Water Efficiency Calculations.
- Flood Risk Analysis.
- Drainage Strategy.
- Community Impact.
- Transport Impacts.
- Daylight Assessments.
- Thermal Comfort.
- The Sourcing of Materials.
- Impact on Pollution.
- Impact on Ecology.
This is not an exhaustive list of what your Sustainability Statement may cover. In addition, the report can include any other aspects of your project’s sustainability plan relevant to your planning application.
Why do I need one?
Usually, Sustainability Statements are needed to undertake projects on greenbelt land. Since 2012, the National Planning Policy Framework outlines that local authorities should only allow building on greenbelt land in exceptional circumstances. Therefore, the local authority may grant a house with exceptional sustainability qualities planning permission.
However, a local authority may also request Sustainability Statements in other circumstances. For example, this is especially the case with large-scale developments.
How are they done?
- Site Plan
- Insulation type/thickness
- U-value of openings
- Specification of heating systems
- Hot water generation
- Percentage of low energy lighting
- Specification of ventilation system
- Renewable technologies
- Accredited construction details
- Flood drainage strategy
- Wider site details
- Traffic counts
- Information about how materials are sourced
- Information about the wildlife and plants in the area
Once we have assessed this information, UKBC will write your Sustainability Statement. This document will include a comprehensive report about which sustainability options you are considering, as well as the impact they will have on cutting carbon emissions and the wider environment.
