For architects
Resolve energy, overheating and fabric requirements while the design can still change. Get clear findings to carry into the drawings and specification.
From the first design question to technical deliverySAP · Overheating · Building compliance
Building performance, from design to completion.
SAP calculations, overheating assessments and practical compliance advice. We help architects and housebuilders make the right decisions early and carry them through to the finished building.

Advice that fits the way you work
Your project. The right support.
Different teams need different answers. Find the information, assessments and support relevant to yours.
For housebuilders
Keep house types, plot variations and specification changes aligned. Connect the design-stage assessments with site testing and final EPCs.

The calculations matter. So do the connections.
Fabric, glazing, ventilation and energy choices affect one another. We look beyond an individual assessment to the decisions the project needs.

How we work
Clear at design. Clear on site. Ready for completion.
The useful result is not just a report. It is knowing what has been checked, what needs to change and what information is still outstanding.
Understand the brief
Confirm the assessment route, current drawings and decisions that need to be made.
Make the findings useful
Set out the options, assumptions and actions for the design and project teams.
Carry the work through
Review agreed changes and connect the final assessment with testing and evidence.
