SAP Calculations for Extensions

Nowadays many extensions exceed the 25% glazing allowance, in relation to new floor area, stipulated in the L1b Building Regulations. In order to gain compliance and satisfy Building Control you will need to produce SAP Calculations.

In order to do this we will carry out two calculations where we will compare the proposed extension to a notional extension of the same size and orientation to demonstrate that the carbon emissions for the proposed extensions are no worse than a notional extension which would only have he 25% glazing.

We have a 100% pass rate and will provide compliant reports to satisfy Building Control.

Great for you

As we will not charge extra for revisions and will advise you on ways to reach compliance, you don’t need to worry that you are going to be left stranded in a difficult position – we will go that extra mile for our clients.

We will guarantee compliance!

For a mere property developer, Part L of the Building Regulations can be rather overwhelming, however, when you have Natalie of RS Energy to guide you through it, what seems an enormous hurdle, disappears. To anyone and everyone who encounters the complexity, to what many of us would consider the irrelevance of outdated Part L, I cannot recommend Natalie high enough to help navigate you through its complexities. In a word, she is phenomenal.
