What does SAP mean?

SAP is short for Standard Assessment Procedure and its the united kingdom government’s method of calculating the energy efficiency of dwellings. Sap calculations are needed to show that your building complies with specified energy targets set down in the building regulations.

That’s pretty much it in a brief overview.

 

When Are SAP Calculations Needed?

Here are most of the reasons you may well be asked for sap calculations

1. For extensions that have more than the permitted amount of glazing
2. For all new properties
3. For a dwelling change of use, e.g altering a commercial building to residential flats.

The 2 main areas that the sap calculations will look at is that the carbon emissions from the dwelling are within set tolerances and that certain elements of the property, for example the windows, roof, floors and walls comply with specified thermal energy targets.

Sap calculations are done by a certified and accredited On Construction Domestic Energy Assessoror OCDEA for short. There is no need to visit the property because all of the calculations are carried out from the building drawings ,so a good set of plans are required. An EPC or Energy Performance Certificate can be produced once the calculations are finished.

If the sap calculations reveal that your property is not compliant, then your Assessor will give you recommendations on upgrades that can be made to make it so. It could be costly if you realise at a late phase in the construction that the building isn’t compliant. So it’s wise to liaise with your Assessor as early on in the project as possible, ideally before any building commences.

Rather than trawl through a entire website to find the explanations you’re looking for, we have offered explanations to the ten most usual queries asked about SAP in Barnet.

Sap Calculations, Just What Are They?

This really is probably the most common query asked. Check out Andrea’s video explanation above, or read the full explanation here on the right.

How Much Do Sap Calculations Cost

We will be pleased to offer discount rates, especially for multiple dwellings that are of the same or very similar design. But typically for a single property the charge will be in the area of £120 – £300. By supplying the plans, it will be possible to get yourself a fixed quote.

What’s The Difference Between Sap and EPC

Before we explain the difference, here is what you will require depending on your project.

For a new build property you’ll need – SAP calculations and an EPC.

For dwelling change of use or conversion you’ll need – Sap Calculations and an EPC.

For overglazing on an existing dwelling you’ll – Sap calculations only.

SAP or Standard Assessment Procedure are the calculations of pre defined data set of a buildings design that’s put together to display the energy performance of a dwelling. EPC stands for Energy Performance Certificate and it’s a summary statement from the SAP calculations in an straightforward document, that can also be used to market or rent a property.

There are really 2 kinds of EPCs. The first is a SAP EPC that is created from building plans when all of the elements of the construction are known. This will normally be needed by building control to show that the property complies with specified targets essential to the building regulations. Building control would also have to see the SAP calculations which shows in detail whether all of the components going into your property comply with the building regulations.

The second type of EPC is the standard one that would be required for anybody who is selling, or renting a property. This type of EPC uses what’s called rdSAP, which stands for Reduced Data Standard Assessment Procedure, and is used where certain thermal values of, for instance, the walls, roof, floors, etc, usually are not precisely known on an existing property. In this case assumed thermal values are used depending on the age of your property. This particular EPC will be no use to show compliance with any building regulations. Sometimes building control would simply ask you for the EPC, however what they would really require are the Sap calculations (which is the data behind the EPC) and the SAP EPC (which is actually summary report from the Sap calculations).

Still perplexed, then call us to get more assistance.

What Are As Built SAP Calculations

These will be the final set of SAP calculations generated after the dwelling has actually been completed to hopefully demonstrate that it is compliant with Part L1A of the building regulations. Prior to the construction starting, it ought to have had a set of “Design Sap” calculations to show that the planned dwelling, in theory at least, will be compliant with Part L1A.

 

 

Can I Do The Sap Calculation Myself

No, this is not something that can be done by yourself. Sap calculations must be carried out by an On Construction Domestic Energy Assessor or OCDEA, using approved Government software. The Assessor has to be approved under one of the certification schemes and is regularly audited to maintain their accreditation.

What Information is Needed For Sap Calculations

Your Assessor would advise you of exactly what is needed. Typically you would need the following:

  • Floor Plans to include sections and elevations
  • Orientation of the property
  • Construction specification of walls, roof and floors
  • Specification for all doors and windows
  • Primary and secondary heating
  • Provision for providing  hot water
  • Any renewable technology (if any)

 

Sap Calculations For New Build

Every new property require Sap calculations to prove compliance with Part L1A (Conservation of fuel and power in new dwellings) of the building regulations.

 

Sap Calculations For Extensions

It’s now quite fashionable to get large bi-folding doors, sky lights and large quantities of glazing on new extensions. However with the latest building regulations the quantity of glazing can be a maximum of 25percent of the floor area of the new extension. Therefore over compensations in the thermal elements in other areas of the property will have to be made to show the CO2 emissions from the existing house along with the planned extension is not any worse than the existing house and an extension where the glazing is within the allowed amount judged against Part L1B of the building regulations.

You should have SAP calculations to find solutions and illustrate compliance.

 

Sap Calculations For Conversions

When you are modifying the use of a dwelling, you will need Sap calculations. {The new dwelling will have to comply with Part L1B of the building regulations.}

 

Do I Need Sap Calculations

You will need Sap calculations for any of the following: 

  • Building a new property
  • Changing the use of an existing property (e.g, a barn conversion, commercial building to residential)
  • Extensions with more than 25% glazing
  • Opening up the main house to an existing conservatory
  • Extension where the extension is more than 50% of the original property wall area
  • Garage conversions
  • If requested by building control

This list is not exhaustive. Phone us, if you are not certain if you require them.
