Net Zero Carbon Supplementary Planning Document
2. Validation Checklist
2.1 To demonstrate compliance with the NZC DPD policies the following documentation will be required to be submitted with planning applications of the relevant type and size. On adoption of this guidance these requirements will be added to the Council's Local Validation List that sets out the information required for validation, assessment and determination of planning applications.
New development of one or more dwellings (C3 or C4 use class) and/or 1,000sqm or more of new non-domestic floorspace – Gross Internal Area (GIA) including non-residential floorspace, hotels (C1 use class) or residential institutions (C2 use class).
A statement should be submitted which outlines technical information relating to the compliance with energy efficiency and carbon emissions reduction requirements of the Net Zero Carbon DPD.
Applicants should provide within their Energy Statement:
- A completed Energy Pro-Forma – see Annex of this SPD. This includes the calculation of the Building Regulations Part L Target Emission Rate (TER) for the building type, the % reductions achieved against this TER, and if required a carbon offset calculation.
- Description of the proposed energy efficiency measures (including passive measures), their suitability and effectiveness for the development proposed, and the energy efficiency benefits they impart to the design to comply with Policy NZC2A.
- Description of the proposed zero- or low-carbon energy sources, their suitability and effectiveness for the development proposed and carbon emission reductions they impart to the design to comply with Policy NZC2B and achieve on site net zero regulated carbon.
- Where Policies NZC2(A), NZC2(B) and on-site net zero regulated carbon are not achieved, justification for why this is not feasible having regard to the development proposed.
More information on how to demonstrate compliance against each of the NZC DPD policies is provided throughout this SPD.
New major development should demonstrate in the energy statement how the embodied carbon of the proposed materials to be used in the development has been considered and reduced where possible, including with regard to the type, life cycle and source of materials to be used.
Proposals for development of 50 or more new dwellings and/or 5,000sqm or more of new nonresidential floorspace should be accompanied by a whole-life embodied carbon assessment of the construction.
Existing Buildings (householder, extensions and conversions) to demonstrate compliance with Policy NZC4 using Energy Proforma – see SPD Annex Part 2.
