Residential energy
SAP for new builds
A clear energy strategy for new houses and apartments, from the first drawings to the completed dwelling.
What this service helps you do.
Bring the energy assessment into the design conversation early. Ordellis reviews the proposed building fabric, heating, ventilation and renewables together, so the specification and the calculations develop as one coordinated package.
What’s included.
- Design-stage SAP calculations and Part L compliance outputs for the agreed regulatory route.
- Review of fabric, glazing, heating, ventilation and renewable energy inputs.
- Practical specification feedback and agreed design updates.
- As-built calculations using the completed building information and evidence.
What we need to get started.
- Location, site plan, plans, elevations and sections.
- Wall, floor and roof build-ups, plus window and door specifications.
- Heating, hot water, ventilation and renewable energy specifications.
- For completion: final specifications and supporting site evidence.
The applicable regulations, methodology and transitional arrangements are confirmed for the individual project. Design-stage outputs are updated when the final building information is available.
Your questions, answered.
When should SAP calculations begin?
At concept or early design stage, when changes to glazing, construction and building services can still be coordinated efficiently.
Can you assess a development with several dwellings?
Send the site layout, dwelling types and unit schedule. The quotation will identify the assessments and outputs required for the agreed development scope.
