An application for planning consent can fix aspects of the design very significantly, depending on the information included. The opportunity for building LCA to guide the design towards lower environmental impacts reduces as a consequence. More credits are, therefore, available for a building LCA submission at ‘concept design’ stage (which must be made before an application for planning consent has been submitted that includes information on external products or materials).
Concept Design Stage Mat 01 submissions
Two factors determine whether a Mat 01 concept design submission is valid: –
• The local authority planning and building control status
• The stage of the project
The table (link below) shows whether a Mat 01 concept design submission is valid according to the status of these two factors.
If a Mat 01 concept design submission has already been made but is now out of date (e.g. due to a change to the client’s brief or planning being refused) it becomes invalid. To achieve the concept design credits, an up-to-date re-submission must be made.
IMPORTANT: This KBCN shall be read in conjunction with KBCN1147 ‘LCA submission stage – ‘Concept design’ and ‘Technical design’’
NOTE: ‘Technical Design’ stage Mat 01 submissions are not affected by the planning status.
NOTE: According to the RIBA Plan of Work, “Planning applications are typically made using the Stage 3 [Developed Design] output”.
