What does SAP mean?

SAP stands for Standard Assessment Procedure and is the united kingdom government’s procedure for determining the energy efficiency of dwellings. These calculations are necessary to demonstrate your building conforms with specified energy targets laid down in the building regs.

As a brief summary, that’s basically it.

 

When Are SAP Calculations Needed?

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

1. For all new homes
2. For a dwelling change of use, e.g altering a single family home to residential flats.
3. For extensions that have more than 25% glazing

The sap calculations are required to show that the dwelling emission rate (DER) and the dwelling fabric energy efficiency (DFEE) comply with certain targets.

A good set of construction drawings must be given to the Assessor, because all the calculations are done from the building drawings ,so there is no need to visit the property. Your Assessor will advise you of precisely what is needed. An EPC or Energy Performance Certificate can be produced once the computations are finished.

If the sap calculations reveal that your property isn’t compliant, the Assessor will give you recommendations on improvements that can be made to make it so. It may be expensive if you find out at a late phase in the construction that the building is not compliant. So it is wise to liaise with your Assessor as early on during the project as possible.

Here we have presented the most frequent questions asked about SAP Calculations in Tipton.

So, What Exactly Are Sap Calculations

This really is probably the most common query asked. Take a look at Andrea’s video explanation above, or read the full explanation here on the right.

Sap Calculations, How Much Are They

If there are various properties with similar forms of constructions, then discounts may apply. For single properties you would be looking in the range of £120 – £300 depending on the intricacy of the construction and also the size. By supplying the plans, it will be possible to get yourself a fixed quote.

What Is The Difference Between Sap and EPC

Before we explain the difference, this is what you will need 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 computations of pre defined data set of a properties design that’s put together to show the energy effectiveness of a property. An EPC or Energy Performance Certificate is a summary report created from the Sap calculations that produces a SAP score from 0 to 100. This score is shown on the EPC as A the highest to G the lowest. It will also list recommendations that would enhance the rating of the dwelling.

There are actually two kinds of EPCs. The first is a SAP EPC which is created from building plans where all of the elements of the construction are known. This would normally be required by building control to show that the dwelling satisfies specified targets essential to the building regulations. Building control would also need to see the SAP calculations which shows in greater detail whether all of the elements going into your property comply with the building regulations.

The second type of EPC is the regular one that would be needed for anyone who is marketing, or renting out a property. This type of EPC uses what’s called rdSAP, which means Reduced Data Standard Assessment Procedure, which is used where specified thermal values of, such as, the walls, roof, floors, etc, usually are not precisely known on an established property. In this situation assumed thermal values are used based on the age of your property. This particular EPC would be no use to show compliance with any building regulations. Sometimes building control would simply ask you to get an EPC, however what they would really need are the Sap calculations (which is the information behind the EPC) and the SAP EPC (which is a summary report from the Sap calculations).

Still confused, then phone us to get more advice.

What Are As Built SAP Calculations

These are the finished set of SAP calculations generated once the dwelling has been completed to confirm that it is compliant with Part L1A of the building regulations. Ahead of the project starting, it ought to have had a set of “Design Sap” calculations to show that the planned building, on paper at least, would be compliant with Part L1A.

 

 

Can I Do The Sap Calculation Myself

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

What Info is Required 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

All new dwelling need to have Sap calculations to prove compliance with Part L1A (Conservation of fuel and power in new dwellings) of the building regs.

 

Sap Calculations For Extensions

It’s now trendy to get large bi-folding doors, sky lights and large amounts of glazing on new extensions. However with the existing building regulations the amount of glazing must be no more than 25percent of the floor area of the new extension. Therefore over compensations in the thermal elements in other parts within the property will have to be made to show the CO2 emissions coming from the current house along with the planned extension is no worse when compared to the existing house and an extension whose glazing is within the permitted amount judged against Part L1B of the building regulations.

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

 

Sap Calculations For Conversions

For anybody who is 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.}

 

Will 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. If you’re not certain whether you require them, then give us a call.
