Residential energy
SAP for renovations
Plan improvements to your home with a clear view of the fabric, heating and energy assessment requirements.
What this service helps you do.
Renovation projects bring existing construction and proposed improvements together. Ordellis reviews the work, the available survey information and the building control brief, then agrees the appropriate calculation route. Where SAP is suitable, the assessment helps coordinate insulation, glazing and building services decisions.
What’s included.
- Review of the renovation scope and the appropriate energy assessment route.
- SAP calculations or comparison assessments where appropriate and included in the quotation.
- Review of retained construction and proposed fabric and building services improvements.
- A report recording the agreed inputs, assumptions and assessment results.
What we need to get started.
- Existing and proposed plans, elevations and sections.
- Survey information for retained walls, floors, roofs and building services.
- Proposed insulation, glazing, heating and ventilation specifications.
- Building control requirements and details of any related extension or conversion.
Not every renovation requires a SAP calculation. The assessment route depends on the proposed work, the existing building and the applicable requirements.
Your questions, answered.
Can you assess insulation and heating improvements together?
Yes. Share the existing information and proposed specifications so the agreed assessment can consider how the improvements work together.
What if my renovation includes an extension?
Send drawings covering the complete proposal. We will agree a coordinated scope for the existing dwelling and the new work.
