DEV32
Helping design teams create highly sustainable, low carbon and compliant schemes
DEV32 Planning Policy
As local planning authorities strengthen their stance on carbon reduction in the drive towards netzero, the South West Devon Joint Local Plan (JLP) – specifically Policy DEV32 – is a requirement for development proposals to actively reduce carbon emissions across the full lifecycle of the building, not just through operational performance.
For replacement dwellings, this introduces a new layer of rigour into the planning process.
Design teams must now demonstrate a robust, evidence-led approach to reducing whole life carbon (WLC) from the initial design stages of a project, which Mesh can assist with.
The New Planning Policy
The DEV32 policy mandates that new developments must:
- Minimise carbon emissions throughout the life of the building, including embodied carbon and operational, maintenance, and end-of-life impact.
- Incorporate passive design and low-carbon technologies.
- Demonstrate a clear understanding of the carbon implications of material choices and construction methods.
The policy prioritises retention and retrofit over rebuild, unless it can be clearly justified.
If this is not feasible, then the replacement building must be demonstrated as the most sustainable solution and incorporate:
- High levels of energy efficiency, such as to Passivhaus standards
- Use of sustainable building materials
- Low or zero carbon impact
- Adaptability and resilience to climate change.
How Mesh can help?
Whole life carbon assessments
We can provide clear justification by undertaking RICS-compliant WLC assessments to support planning applications where new build is proposed. This would provide clear insight into:
- Embodied carbon from both materials and construction
- Operational carbon from energy use
- Lifecycle impact scenarios, including refurbishment cycles and end-of-life deconstruction.
Optimisation of materials and building engineering systems
Our building performance consultants have an indepth working knowledge of DEV32 policy, and partner closely with architects and clients to inform the material selection process and achieve the optimum balance between building performance, durability, and embodied carbon. By using a combination of energy performance and specialist expertise in building services, we can significantly improve the likelihood of a design meeting DEV32 targets – cost efficiently and without overengineering.
Informed support for the planning and design process
We can provide clear and compelling evidence and apply technical rigour to demonstrate that the planning submission goes beyond minimum compliance and actively aligns with the intent of DEV32 policy. Our aim is to strengthen planning applications and reduce the risk of delays resulting from re-submissions or amendments.

Whole Life Cycle Carbon assessments – true picture of a building’s carbon impact on the environment
In this 1st webinar of 2024 Mesh Energy's Richard Bowman provides:
1) An introduction to whole life carbon counting structure,
2) where in the UK the policy applies,
3) how it feeds into Part Z - a proposed amendment to the Building Regulations
4) draw upon findings from The Low Energy Transformation Initiative
5) how we take BIM info from IES into the carbon software and the outcomes
Richard Bowman is an experienced building performance consultant undertaking Dynamic thermal modelling, CBDM, overheating, CFD analysis, design cost+carbon benefit analysis, energy hierarchy design, whole life carbon analysis at Mesh Energy.
