Retrofit & Decarbonisation Support
Full Retrofit Feasibility & Technical Partnership Services
At Focus 360 Energy, we provide specialist residential or commercial retrofit feasibility, decarbonising support, and technical partnership services. Our consultancy integrates PAS 2035 / ECO4 modelling, EPC improvements, payback analyses, and total carbon-cost studies. We’re your trusted partner for delivering data-driven, future-proofed retrofit planning.
Residential Retrofit & Decarbonising (SAP-based)
What We Offer:
- Retrofit feasibility reports: Assess the whole fabric of a building using SAP calculations, identifying areas of missing insulation, overheating risk, ventilation, and EPC improvement potential.
- Expertise in PAS 2035 compliant retrofit design and assessment, applying a fabric-first approach, first addressing insulation and airtightness, then upgrading the heating system
- ECO4 modelling to model grant-eligible retrofit options and view incentives related to achieving EPC C or better.
- Lifecycle payback period for retrofit technologies: from heat pumps to insulation, we balance initial cost against future energy and carbon savings.
- Comprehensive cost-of-carbon saving reports: quantify CO₂ avoided, financial return, and environmental impact.
- Practical assistance for Retrofit Coordinators: We deliver feasibility assessments, retrofit strategy, compliance documentation, and post-project verification, to PAS 2035 standards
Why It Matters:
- Needed for grant eligibility under ECO4 and other schemes.
- Empowers landlords and developers with robust data for financial performance and regulatory compliance.
- Streamlines the compliance path for PAS 2035‑aligned retrofit delivery, avoiding missteps in deep retrofit projects
Commercial Retrofit & Decarbonising (SBEM-based)
What We Offer:
- SBEM calculation-based retrofit feasibility studies: Analyse building energy performance, determine retrofit priorities, and define embodied vs. operational carbon.
- Bespoke EPC improvements evaluation to uplift certification and market value.
- PAS 2035 methodologies applied to commercial counterparts, systems thinking, whole-building decarbonisation, and integrated assessment.
- Economic breakdowns, including payback periods, cost of carbon savings, and investment justification for low-carbon technologies like insulation, HVAC, and renewables.
- Technical partnerships for developers and estate managers, providing easy, actionable retrofit recommendations with ongoing monitoring of performance.
Why It Matters:
- Assists landlord and developer decision-making, demonstrating return on retrofit investment.
- Guarantees regulatory compliance with Building Regulations Part L and broader sustainability goals.
- Maximises portfolio value through sustainable, efficient building assets.
Our Process Flow
1. Initial Retrofit Feasibility
Feasibility testing via SAP (domestic) or SBEM (non-domestic), with PAS 2035 / ECO4 modelling for retrofit pathways.
2. Retrofit Strategy & Modelling
Identify fabric, HVAC, and renewables combinations for optimal EPC improvements and carbon-cost payback profiles.
3. Technical Design Support
In-depth retrofit strategy and compliance report, including PAS 2035-compatible risk route studies and coordinator liaison.
4. Implementation Support
Support through procurement, installation, and handover, including energy monitoring advice and commissioning.
5. Performance Verification
Report outcomes, provide cost-of-carbon savings reports, and lessons for future improvement feedback, closing the PAS 2035 loop.
