SAP Calculations and New Dwellings
If you are building a new home in the UK, the Building Regulations will require a SAP Calculation for each new property and we will work with you to establish a compliant design. We will help make Building Regulation compliance easier by offering solutions and guidance throughout the design and build process. The Building Regulations requirement is that your new build design does not exceed a unique target for both carbon emissions and thermal performance of the fabric.
We can save you money by assessing from architects drawings the building materials and heating products specify to model your new build, meaning that there’s no need for costly site visits. We will never fail a project and will always provide solutions and feedback for achieving a pass.
Appoint EAC South West as early as possible; it is important to involve us as early as possible; if we become involved in a scheme half way through a build it can be difficult to change the energy performance of the building.
The SAP assessment process is split into two stages:
Design Stage
- Design Draft – the initial production of all the SAP documentation should be carried out at the same time as the design of the dwelling or extension. This is when any changes to the building design can be made before either a Planning or Building Regulation application is made.
- Design Final – when the design is agreed we will produce a SAP report showing compliance with the Building Regulations and a Predicted Energy Assessment which is required by Building Control.
As Built Stage
- As Built Draft – during the build, should any design elements be changed we will need to be informed so that we can check that compliance with SAP and the Building Regulations is maintained and if not discuss options available.
- As Built Final - once the project build has been completed, any final corrections to the SAP can be made and the As Built Final SAP Energy Performance Report and the Energy Performance Certificate (EPC) can be lodged with Land Mark and issued.
- Air Pressure Test – the result (copy of certificate) is sent to EAC South West and we will replace the assumed Design Air Leakage with the actual As Built Air Leakage rate
- Design Draft SAP calculations are produced
EAC South West will require the following to carry out a SAP calculation
- Site address and post code
- Site plan to include a north direction point
- Scaled floor plans, building elevation and section drawings
- Construction details of floors, walls and external walls
- Details of windows and doors
- Details of the heating and hot water system
- Ventilation
- Lighting and any renewable technology used
We will require the details to be emailed to enquiry@eacsouthwest.co.uk or posted to EAC South West, 12 Mount Lidden, Penzance TR18 4PA
We can make a Building Regulation application on your behalf
We will take time to understand what you want and then deliver what is required for Building Regulation compliance.
