SAP Calculations

The Process

If you are building a new dwelling or converting a building to form a dwelling you need to demonstrate compliance with Part L of the Building Regulations by providing SAP Calculations & an Energy Performance Certificate. This shows the predicted energy efficiency of the dwelling.
At Oakland Energy we can guide you through the complete SAP process.
There are essentially two stages:

Design Stage

Upon receipt of construction drawings and specification we can provide you with all of the relevant SAP documentation to be submitted to Building Control as part of your Building Regulations application.

As Built Stage

Once the dwelling has been built and the construction methods and specification are confirmed, we can then release the Energy Performance Certificate. The EPC is required to sell the property.
Please feel free to contact us to discuss your requirements.

Excessive Glazing Calculations

If you are constructing an over glazed extension with total external openings in excess of 25% of the extension floor area then calculations must be provided to Building Control to demonstrate compliance with Part L1B of the Building Regulations.

At Oakland Energy we can assist you through this process by either an ‘area weighted’ u value method or by a full sap calculation including the existing property.
Please feel free to contact us to discuss your requirements.

Energy Statements

Many Local Authorities are placing energy related requirements on new build dwellings and extensions. At Oakland Energy we can assist you with understanding what is required and how to cost effectively meet the planning obligation.
